PURPOSE: Gastric cancer (GC) is among the leading causes of cancer mortality worldwide. The objective of this study was to investigate the association between dietary fiber intake and GC. METHODS: We pooled data from 11 population or hospital-based case-control studies included in the Stomach Cancer Pooling (StoP) Project, for a total of 4865 histologically confirmed cases and 10,626 controls. Intake of dietary fibers and other dietary factors was collected using food frequency questionnaires. We calculated the odds ratios (OR) and 95% confidence intervals (CI) of the association between dietary fiber intake and GC by using a multivariable logistic regression model adjusted for study site, sex, age, caloric intake, smoking, fruit and vegetable intake, and socioeconomic status. We conducted stratified analyses by these factors, as well as GC anatomical site and histological type. RESULTS: The OR of GC for an increase of one quartile of fiber intake was 0.91 (95% CI: 0.85, 0.97), that for the highest compared to the lowest quartile of dietary fiber intake was 0.72 (95% CI: 0.59, 0.88). Results were similar irrespective of anatomical site and histological type. CONCLUSION: Our analysis supports the hypothesis that dietary fiber intake may exert a protective effect on GC.

Emerging evidence suggests that gut bacteria‐derived trimethylamine N‐oxide (TMAO) elevates the risk of cardiovascular disease, and dietary fiber holds the potential to attenuate TMAO formation. However, the effectiveness of dietary fiber, such as inulin, in inhibiting TMAO formation remains controversial. Therefore, this study investigated the effect of inulin supplementation on TMAO formation in mice with high TMAO levels induced by a high‐fat diet (HFD) combined with choline and L‐carnitine. Results showed that HFD treatment significantly elevated blood TMAO concentrations and increased the abundances of TMAO formation‐associated gut bacteria, as well as the abundances of functional genes responsible for TMA formation. While the supplementation of choline and L‐carnitine greatly enhanced blood trimethylamine (TMA) and TMAO levels, inulin supplementation did not significantly affect TMAO levels and had limited impact on TMA‐associated gut bacteria, except for Desulfitobacterium hafniense.

This study aims to investigate the effect of different ratios of soluble and insoluble dietary fiber (0/100, 25/75, 40/60, 55/45, 70/30, 85/15, 100/0) in rice bran treated with or without extrusion cooking on the physicochemical and structural properties of rice starch. As the ratio of soluble dietary fiber (SDF) increases, the PV (peak viscosity), FV (final viscosity), SB (setback value), and BD (breakdown value) of starch are significantly decreased, indicating that a higher SDF ratio can delay the short‐term retrogradation of starch. Compared with the unextruded rice bran SDF/IDF starch gel, the content of weak bond water and free water in the extruded rice bran SDF/IDF starch gel is higher while the content of strong bond water in the starch gel is lower at the same SDF/IDF ratio. Meanwhile, for the results X‐ray diffraction (XRD) and fourier transform infrared spectrum (FTIR), the rice starch with the extruded rice bran SDF/IDF ratio of 25:75 shows the lowest relative crystallinity of 3.48% and the lowest peak to height ratio of FTIR (1047 cm−1/1022 cm−1) of 1.0746, suggesting that the inhibition effect on rice starch retrogradation is better. This may be beneficial for the utilization of different ratios of SDF/IDF from extruded rice bran and physicochemical properties improvement of rice starch gel. [ABSTRACT FROM AUTHOR]

Green technology, encompassing sustainable practices in food production, extends to dietary fiber extraction. This study aimed to enhance dietary fiber extraction from the selected barley varieties (Jou‐17, Sultan‐17, and Pearl‐21) using the ultrasonic‐assisted extraction (UAE) technique. This process involved washing, drying, de‐fatting (using ethanol as green solvent), and protein removal steps. The response surface methodology (RSM) technique was used to optimize the yield of soluble dietary fiber (SDF; β‐glucan) with time, temperature, and power. Optimal conditions yielded the highest SDF (5.21%) in all selected varieties after 17.5 min at 41.70°C with 130.5 W. FTIR pattern confirmed the functional group in the tested sample. TGA and DSC spectra determined the thermal of SDF (β‐glucan). Monosaccharide composition confirmed that SDF (β‐glucan) is glucose in nature. Proximate analysis indicated that Jou‐17 had the highest moisture (13.4%) and crude fiber (10.10%) content. Sultan‐17, on the other hand, had the maximum levels of ash (2.75%), crude fat (1.22%), and protein (8.84%). The NFE, water‐holding capacity, oil‐holding capacity, and foaming capacity of extracted SDF (β‐glucan) in the “Pearl‐21” barley variety were determined to be 78.37%, 14.07 g/g, 6.99 g/g, and 126.17%, whereas highest foaming‐stability (96.26%) was observed in Jou‐17 variety. PCA also confirmed the association in studied variables. In a nutshell, optimizing the extraction of SDF (β‐glucan) from the selected barley varieties using green technology and its favorable properties opens up promising paths for future endeavors and contributes to the advancement of sustainable and health‐conscious practices in the food industry.

Background: Little is known on the prospective associations between an empirically derived dietary pattern (DP) and life satisfaction among adolescents. This PUTRA-Adol follow-up study aimed to assess the prospective associations between the empirically derived DP and life satisfaction during adolescence. Methods: A total of 585 and 262 adolescents participated in the baseline PUTRA-Adol study in 2016 and PUTRA-Adol follow-up study in 2019–2020, respectively. These adolescents were recruited from three southern states in peninsular Malaysia, namely Negeri Sembilan, Melaka and Johor. Dietary assessments were estimated using a validated food frequency questionnaire (FFQ) while a Multidimensional Students' Life Satisfaction Scale (MSLSS) was used to measure life satisfaction at baseline in 2016 as well as at follow-up in 2019–2020. A DP characterised by foods high in free sugar and energy dense was identified using reduced rank regression (RRR), cross-sectionally at baseline and was reported elsewhere. Similar RRR analysis was used to find a DP that best explained the variation in response variables linked to poorer life satisfaction, including dietary energy density (DED), fiber density, and percentage of energy from total fat and sugar at the PUTRA-Adol follow-up study. Prospective relationship between adherence to the identified DPs and overall life satisfaction scores as well as its domains between 2016 and 2019–2020 were evaluated using generalized estimating equation models (GEE). Results: A DP characterized by high intakes of percentage energy from sugar, fibre and low in DED and percentage energy from total fat was identified at the 2019–2020 follow-up. The identified DP explained 11% of total variations in the response variables and was characterized by high intakes of sweets, sugar sweetened beverages (SSB) and fruits. Female adolescents [67.6(8.9)] had a mean (SD) of life satisfaction that was higher than male adolescents [67.5(10.8)] p < 0.05 in 2019–2020. Prospective analysis found a significant positive association between the identified DP and school domain, in male adolescents (β = 0.117; 95% CI 0.001, 0.234) and an inverse relationship between the DP z-score and self-domain in all adolescents (β = − 0.060; 95% CI − 0.115, − 0.005) from 2016 to 2019–2020. Conclusions: An increasing score for the predominant 'High sugar and High fibre' DP was prospectively associated with increasing life satisfaction score for the school domain in male adolescents and decreasing score for self-domain in both male and females during adolescence. A lifestyle intervention targeting reduced dietary intakes, particularly sugar, may improve life satisfaction in adolescents and promote healthier future without compromising dietary intakes for chronic disease prevention later in life.

Consumers are increasingly looking for healthier and sustainable diets. Plant-based diets rich in legumes satisfy this demand. Legumes contain protein, dietary fibers and starch. Technological processes can separate these fractions, which can be used as supplements, or as ingredients. Nonetheless, legumes are susceptible to fungal infection, causing a potential health concern, since some fungi can produce mycotoxins: toxic secondary metabolites. The aim of this work was to analyze the fate of mycotoxins during different stages of the production process of legume derived products from the raw materials to final products. An extraction followed by liquid chromatography-tandem mass spectrometry was used for the analysis, revealing the presence of enniatin B (ENN B), alternariol monomethyl ether (AME), deoxynivalenol, T2-toxin, nivalenol, fumonisin B1 and sterigmatocystin in raw materials, intermediate products and side streams. The alkaline solubilization steps, were effective in reducing ENN B; however, AME was found in one of the final products. [ABSTRACT FROM AUTHOR]

Purpose: Obesity is a primary risk factor for knee osteoarthritis (OA). Prebiotics enhance beneficial gut microbes and can reduce body fat and inflammation. Our objective was to examine if a 6-month prebiotic intervention improved physical function in adults with knee osteoarthritis and obesity. We also measured knee pain, body composition, quality of life, gut microbiota, inflammatory markers, and serum metabolomics. Methods: Adults (n = 54, mostly women) with co-morbid obesity (BMI > 30 kg/m2) and unilateral/bilateral knee OA were randomly assigned to prebiotic (oligofructose-enriched inulin; 16 g/day; n = 31) or isocaloric placebo (maltodextrin; n = 21) for 6 months. Performance based-tests, knee pain, quality of life, serum metabolomics and inflammatory markers, and fecal microbiota and short-chain fatty acids were assessed. Results: Significant between group differences were detected for the change in timed-up-and-go test, 40 m fast paced walk test, and hand grip strength test from baseline that favored prebiotic over placebo. Prebiotic also reduced trunk fat mass (kg) at 6 months and trunk fat (%) at 3 months compared to placebo. There was a trend (p = 0.059) for reduced knee pain at 6 months with prebiotic versus placebo. In gut microbiota analysis, a total of 37 amplicon sequence variants differed between groups. Bifidobacterium abundance was positively correlated with distance walked in the 6-min walk test and hand grip strength. At 6 months, there was a significant separation of serum metabolites between groups with upregulation of phenylalanine and tyrosine metabolism with prebiotic. Conclusion: Prebiotics may hold promise for conservative management of knee osteoarthritis in adults with obesity and larger trials are warranted. Clinical Trial Registration: Clinicaltrials.gov/study/NCT04172688. [ABSTRACT FROM AUTHOR]

Practical Application Grape pomace (GP) is a waste product of the winemaking process and has been proposed as a nutritionally beneficial ingredient, as it contains phenolic compounds, dietary fiber, and antioxidant activity. It can be a polarizing ingredient due to its flavor components. Familiarity has been found to influence consumers’ preferences and sensory perception of food. A sensory test was conducted to evaluate the acceptance, sensory perception, and emotional response to pasta sauces containing GP (3% [3GP], 6% [6GP], 9% [9GP] by volume and control without GP addition). The sensory trials included wine consumers (n = 44) and nonconsumers of wine (n = 58) to determine how consumers’ familiarity with the flavor properties of GP influenced their perception of the pasta sauce. Overall, the addition of GP decreased the liking scores of the GP‐containing sauces, but the wine consumers’ hedonic scores for the control, 3GP, and 9GP were significantly higher than the nonconsumers. Both consumer groups identified that the samples with a higher amount of GP addition were associated with sour, bitter, astringency, grainy, and gritty attributes. However, the wine consumers used more positive emotions to describe their emotional response to the GP‐containing samples. The study identified that GP led to off‐flavors and textures in the pasta sauces.GP is currently a waste product, but it has many nutritional benefits. Consumers are increasingly looking for nutritional benefits from their food. When incorporated into pasta sauces, GP decreased the acceptance of the pasta sauce and negatively impacted the flavor and texture. Familiarity has been found to impact consumer acceptance, and wine consumers had a more positive emotional response and higher hedonic scores in response to the GP‐containing pasta sauce than nonconsumers of wine.

Citrus fruits are widely consumed for their nutritional and health benefits. They belong to the Rutaceae and have many varieties, such as sweet orange (Citrus sinensis), which is the most popular. Citrus fruits are rich in water (>80%), dietary fiber, and vitamins. They also contain bioactive components, which may modulate energy metabolism and lipid oxidation through various mechanisms. These mechanisms include stimulating β3-adrenergic receptors, increasing mitochondrial biogenesis and thermogenesis, activating AMP kinase and peroxisome proliferator-activated receptor-gamma coactivator-1α pathways, inhibiting lipogenesis and lipid accumulation, and inducing browning of white adipose tissue. This review summarizes the mechanisms and outcomes of citrus fruits and their metabolites on energy metabolism and body weight in different experimental models. The literature was searched for in vitro and in vivo animal and human studies that investigated the effects of citrus consumption on energy expenditure, thermogenesis, adipogenesis, and lipid accumulation. Citrus fruits and their metabolites have shown promising effects on energy metabolism and lipid oxidation in in vitro and in vivo animal studies. However, the evidence from human studies is limited and inconsistent. Possible reasons for the discrepancy are briefly discussed, and knowledge gaps and research needs are identified for future studies. Citrus fruits may have beneficial effects on energy metabolism and body weight, but more rigorous and well-designed human trials are needed to confirm their efficacy and safety.

Objective: Limited studies have been conducted on insulin index/load, with inconsistent results regarding the glycemic index/load in relation to cardiometabolic risk factors among people with diabetes. The present study aimed to reveal the association of dietary glycemic index and load and dietary insulin index and load with cardiometabolic risk factors among people with diabetes. Method: This cross-sectional study was performed on 88 adults with diabetes who enrolled in the Cohort Study of Employees of Shiraz University of Medical Sciences. The scores of dietary glycemic index (DGI), dietary glycemic load (DGL), dietary insulin index (DII), and dietary insulin load (DIL) were measured using a 116-item food frequency questionnaire (FFQ). Multivariate linear regressions were used to associate each dietary score with fasting blood glucose (FBG), triglyceride, total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and systolic and diastolic blood pressure. Results: DGI was significantly associated with serum FBG (β; 0.24, 95% CI; 0.02, 0.46) and triglyceride (β; 0.53, 95% CI; 0.002, 1.06) levels but not TC, HDL, LDL, or blood pressure after adjusting for age, sex, education, marital status, smoking, body mass index, energy intake, physical activity, having other diseases, and family history of diabetes. Neither DGL, DII, nor DIL was significantly associated with each of the cardiometabolic risk factors after controlling for the confounders. Conclusion: A diet with a higher glycemic index accompanied by a higher serum FBG and triglyceride level. Further studies are needed to determine the association of DGL, DII, and DIL with cardiometabolic risk factors. [ABSTRACT FROM AUTHOR]

BACKGROUND: Ulcerative colitis (UC) refers to an idiopathic chronic inflammatory bowel disease that starts with inflammation of the intestinal mucosa. Dietary fiber plays a crucial role in maintaining the normal architecture of the intestinal mucosa. In this study, the protective effect and potential mechanism of soluble dietary fiber from Rosa roxburghii Tratt residue (SDFR) on dextran sulfate sodium (DSS)‐induced UC mice were explored. RESULTS: The results revealed that SDFR could ameliorate body weight loss and pathological injury, improve the structure and crypt destruction in colon in DSS‐induced mice. Moreover, the levels of NO, IL‐1β, TNF‐α, MPO and protein expression of iNOS and COX‐2 were decreased after administration of SDFR. Notably, nontargeted metabolomics analysis indicated that there were significant differences in 51 potential metabolites in serum between the DSS and control groups. SDFR intervention could regulate aberrant alterations of these metabolites and mitigate UC via regulating metabolic pathways, including arachidonic acid and glycerophospholipid metabolism. CONCLUSION: This study provides novel evidence that SDFR could be used as a potential modulator to relieve UC. Also, the results provide a theoretical basis for the utilization of byproducts in Rosa roxburghii Tratt fruit processing. © 2024 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

The rampant use of antibiotics has led to the emergence of multidrug resistance and is often coupled with gut dysbiosis. To circumvent the harmful impact of antibiotics, probiotics have emerged as an effective intervention. However, while the new probiotics are being added to the list, more recently, the nature and role of their counterparts, viz. prebiotics, postbiotics and parabiotics have also drawn considerable attention. As such, intricate relationships among these gut-biotics vis-à-vis their role in imparting health benefits is to be delineated in a holistic manner. Prebiotic dietary fibers are selectively fermented by probiotics and promote their colonization in the gut. The proliferation of probiotics leads to production of fermentation by-products (postbiotics) which affect the growth of enteropathogens by lowering the pH and producing inhibitory bacteriocins. After completing life-cycle, their dead remnants (parabiotics e.g. exopolysaccharides and cell wall glycoproteins) also inhibit adhesion and biofilm formation of pathogens on the gut epithelium. These beneficial effects are not just endemic to gut but a systemic response is witnessed at different gut-organ axes. Thus, to decipher the role of probiotics, it is imperative to unravel the interdependence between these components. This review elaborates on the recent advancements on various aspects of these gut-biotics and the mechanism of potential attributes like anti-oxidant, anti-inflammatory, anti-neoplastic, anti-lipidemic and anti-hyperglycemic benefits.

Fermentable oligo-, di- and monosaccharides and polyols (FODMAP) comprise several previously unrelated carbohydrates, such as fructans, fructo-oligosaccharides, galacto-oligosaccharides, fructose (in excess of glucose), mannitol and sorbitol, and among others. For many patients with gastro-intestinal disorders, such as irritable bowel syndrome, the ingestion of FODMAP triggers symptoms and causes discomfort. Among the main contributors to the dietary FODMAP intake are baking products, in particular bread as a major global staple food. This is primarily due to the fructan content of the cereal flours, but also process induced accumulation of FODMAP is possible. To provide low-FODMAP baking products, researchers have investigated various approaches, such as bio-process reduction by yeast, lactic acid bacteria, germination of the raw material or the use of exogenous enzymes. In addition, the selection of appropriate ingredients, which are either naturally or after pretreatment suitable for low-FODMAP products, is discussed. The sensory and nutritional quality of low-FODMAP baking products is another issue, that is addressed, with particular focus on providing sufficient dietary fiber intake. Based on this information, the current state of low-FODMAP baking and future research necessities, to establish practical strategies for low-FODMAP products, are evaluated in this article.

Wine pomace (WP) is a major byproduct generated during winemaking, and skin pomace (SKP) comprises one of the most valuable components of WP. Since SKP differs in composition and properties from seed pomace (SDP), precise knowledge of SKP will aid the wine industry in the development of novel, high-value products. The current review summarizes recent advances in research relating to SKP presents a comprehensive description of the generation, composition, and bioactive components, primarily focusing on the biological activities of SKP, including antioxidant, gastrointestinal health promotion, antibacterial, anti-inflammatory, anticancer, and metabolic disease alleviation properties. Currently, the separation and recovery of skins and seeds is an important trend in the wine industry for the disposal of winemaking byproducts. In comparison to SDP, SKP is rich in polyphenols including anthocyanins, flavonols, phenolic acids, stilbenes, and some proanthocyanidins, as well as dietary fiber (DF). These distinctive benefits afford SKP the opportunity for further development and application. Accordingly, the health-promoting mechanism and appropriate application of SKP will be further elucidated in terms of physiological activity, with the progress of biochemical technology and the deepening of related research.

Gut microbiota (GMB) in humans plays a crucial role in health and diseases. Diet can regulate the composition and function of GMB which are associated with different human diseases. Dietary fibers can induce different health benefits through stimulation of beneficial GMB. β-glucans (BGs) as dietary fibers have gained much interest due to their various functional properties. They can have therapeutic roles on gut health based on modulation of GMB, intestinal fermentation, production of different metabolites, and so on. There is an increasing interest in food industries in commercial application of BG as a bioactive substance into food formulations. The aim of this review is considering the metabolizing of BGs by GMB, effects of BGs on the variation of GMB population, influence of BGs on the gut infections, prebiotic effects of BGs in the gut, in vivo and in vitro fermentation of BGs and effects of processing on BG fermentability.

There is increasing attention on the modification of dietary fiber (DF), since its effective improvement on properties and functions of DF. Modification of DF can change their structure and functions to enhance their bioactivities, and endow them with huge application potential in the field of food and nutrition. Here, we classified and explained the different modification methods of DF, especially dietary polysaccharides. Different modification methods exert variable effects on the chemical structure of DF such as molecular weight, monosaccharide composition, functional groups, chain structure, and conformation. Moreover, we have discussed the change in physicochemical properties and biological activities of DF, resulting from alterations in the chemical structure of DF, along with a few applications of modified DF. Finally, we have summarized the modified effects of DF. This review will provide a foundation for further studies on DF modification and promote the future application of DF in food products.

Hempseed (Cannabis sativa L.) is a valuable source of oil and a quality vegetable protein source, but little is known about its fiber composition. This study provides the most extensive characterization of hempseed cell wall polysaccharides to date. Quantification of total dietary fiber (TDF) and acetyl bromide soluble lignin (ABSL), monosaccharide composition through two complimentary hydrolysis methods (Saeman hydrolysis and methanolysis), and linkage analysis via derivatization of monosaccharides to partially methylated alditol acetates (PMAAs) were done. More detailed profiling of hempseed xyloglucans and pectic arabinans and galactans was performed via targeted enzymatic generation and quantification of characteristic oligosaccharides. Hempseed's cell wall polysaccharide profile is consistent with the primary cell walls of dicots, but it is particularly abundant in linear xylans, presumably from secondary cell walls. The hempseed water-insoluble cell wall material was mostly composed of cellulose and xylans, but pectins (including arabinans with a low degree of branching and galactans), xyloglucans with L- and F-motifs and a relatively low substitution rate, and mannans were also present. These data show that hempseed is a good source of complex dietary fiber for human diets and a potential fiber additive for herbivorous livestock diets. Potential consequences of these carbohydrate structural details on hempseed's microbial fermentability are discussed. [ABSTRACT FROM AUTHOR]

Apple (Malus domestica) is a reliable source of nutrients to increase the bioactive compounds intake in the human body. In the market, the development of apple is still growing, not only in the hybridization of new cultivars, but also in the functional food products, based on apple's bioactive compounds. In this paper, we review the recent studies about the chemical composition of apples, including carbohydrates, proteins, lipids, dietary fibers, minerals, vitamins, phenolics, and other compounds, from various cultivars, grown in different countries or regions. Among the bioactive compounds in apple, the phenolic compounds, including hydroxybenzoic acids, hydroxycinnamic acids, flavanols and their oligo- and polymeric structure, flavonols, dihydrochalcones, and anthocyanins, majorly contribute to beneficial biological impacts. Therefore, the extraction process might be the most critical step to recover all the phenolics from apple and could be used in various food product developments. In this paper, the comparison of conventional and developed phenolic extraction methods is also reviewed in various apple products (flesh, peel, pomace, pulp, etc.). The selection of food grade and green solvents in the optimal phenolic extraction methods could reduce the environmental issues, thus supports sustainability and can be safer for consumers. To sum up, this paper may help the readers, both at general household and industrial levels, to understand the nutritional composition of various apple cultivars from different regions and to select the optimum conditions for apple's phenolic extraction, based on recent studies.

Background and Objectives: While the beer style expresses beer's diversity by its sensory properties, ingredients, production method, recipe, and history, fibrous fraction and functional properties of Brewers' spent grain (BSG) vary according to the beer style. To investigate the effects of beer style, the physicochemical and technological properties of BSG breads containing 10% of dry BSG from beers Baltic Porter (BP), India Pale Ale (IPA), and Weissbier (W) were evaluated according to their sensory quality, firmness, staling rate, crumb color and structure, proximal composition, and dietary fiber content. Findings: All evaluated parameters of BSG breads were significantly affected, but differed according to the BSG source. All investigated BSG significantly increased the dietary fiber levels of breads, while only BP bread presented enhanced protein content. Conclusions: Higher deleterious BSG effects in bread quality were verified in IPA bread, which presented the highest dietary fiber content, while the fiber content of BP and W breads were inconsistent with bread quality. Significance and Novelty: Although BSG incorporation up to 10% was reported as a limit for obtaining acceptable BSG breads, beer style must also be considered because specific volume, staling rate, and acceptance of breads may be negatively affected by its fiber content.

Carao honey is a potential functional ingredient that can generate added value to food products enriched by reducing waste. In many countries, carao has been utilized for therapeutic purposes since this type of plant extract can inhibit the growth against the most common dermatophytes, a pathogenic fungus that grows on the skin, mucous membranes, hair, nails, feathers, and other body surfaces, causing ringworm and related diseases. The physicochemical characteristics of the cookies were also investigated, which included aW, proximate analysis, hardness, and color. A sensory study was carried out to determine the rejection threshold, acceptability, purchase intent, and general taste of 90 consumers. The gluten-free cookies were prepared with carao honey as a partial substitute for rice flour in different percentages (0%, 2.5%, 5%, and 10%). The carao honey proximate composition, rheological properties, and pasting properties were analyzed. It was emphasized that incorporating carao honey into cookies improves the ingredient's sustainability. The impact of carao on the physicochemical and sensory properties of cookies was evident in color, flavor, and smell. According to the results, only samples with 2.5% carao were accepted regarding flavor and smell. Overall, liking scores, age, and flavor were the most significant predictors of purchase intent. The information given to panelists did not significantly (p < 0.05) influence liking scores only for cookies. According to physicochemical analysis, carao honey flour was high in carbohydrates (88%). The incorporation of carao produced cookies with darker colors and a softer texture. The study demonstrated that carao flour could be included to produce sensorial accepted cookies at a 2.5% addition level as an alternative in the food industry that benefits from environmental sustainability and, at the nutritional level, improves the availability of nutrients, mainly sugars and proteins.

Legume flours are an increasingly popular food ingredient. Thermal treatments applied prior to milling legumes and granulometry can modify flour properties, altering sensory, digestibility and functional attributes. Raw and treated (soaked and cooked) lentil flours of different granulometry were produced. The applied treatment resulted in an increase in fiber content (25.4 vs. 27.6% for raw and treated lentil flour, respectively) and water absorption capacity. It also led to a decrease in ash content (3.3 vs. 1.8% for raw and treated, respectively) and a darker flour. Treated lentil flour was mainly composed of fractions of high granulometry, which could be beneficial for products where a lower glycemic index is sought, as they demonstrated higher fiber and lower carbohydrate content than the finer fractions. Treated flour may be used as an ingredient in the development of raw products, including beverages and desserts, due to its reduced anti-nutritional compounds' content and enhanced organoleptic aspects. The obtained results allow an in-depth characterization of raw and treated lentils flour with different particle sizes to consider a formal and complete standardization of these flours and for understanding their utility and specific food applications.

Very low energy diets (VLEDs) contain <800 kcal/day and typically comprise formulated meal replacement products with adequate protein and micronutrients. Food-based VLEDs are an alternative approach, but it is uncertain whether they can provide adequate nutrition within an 800 kcal/day restriction. This analysis aimed to assess the nutritional adequacy of food-based VLEDs compared with formula VLEDs. A systematized literature review was conducted to identify balanced food-based VLEDs by searching five scientific databases from inception to 23 March 2023 and online sources between 1 and 7 May 2023. Ultimately, nine diets were analyzed for nutritional content and compared with Codex Alimentarius standards for formula foods, and Australian estimated average requirement and adequate intake (AI) for adults 19–50 years. Optifast® was used as a comparator. None of the VLEDs met all nutritional benchmarks. Three food-based diets had nutrient profiles similar to formula VLEDs, with one being adequate for all nutrients except thiamine, magnesium and zinc in men and iron in women. All VLEDs, including Optifast®, did not meet AI for dietary fiber, except one. In general, food-based VLEDs offered more fiber than Optifast®. In conclusion, food-based VLEDs were inadequate in certain micronutrients but offered more dietary fiber than formula VLEDs. These nutritional deficits do not preclude food-based VLEDs from being recommended, provided they are addressed. [ABSTRACT FROM AUTHOR]

Nowadays, prickly pears are increasingly being processed into juices, and a variety of processed products are offered to consumers. As a consequence, a significant amount of by-product is generated, possessing a large potential for utilization as a source of dietary, and functional fibers. This work aimed to study and compare the effect of the incorporation of red prickly pear by-products (RPPBP) and green prickly pear by-products (GPPBP) from fruit processing as potential ingredients in cakes to promote them as high-value products. The proximate, morphological, and physical characteristics of powders of prickly pear by-products (PPBP) were investigated. The results indicated that the lipid content was approximately 5% for the two prickly pears by-products, and the protein content was between 12.7% and 15.31%. RPPBP and GPPBP are rich in total dietary fiber and exhibited a good water retention capacity (WRC) and oil retention capacity. RPPBP demonstrated better functional properties compared to GPPBP in terms of WRC and swelling capacity, with values of 6.37 g/g and 4.0 ml/g, respectively. In comparison, GPPBP showed a higher least gelation concentration that could enhance texture within products. We investigated the aptitude of RPPBP and GPPBP [1%, 2%, 5%, 10%, and 15% (g/100 g)] to be mixed with wheat flour for cakes preparation through the analysis of the physical characteristics, color, and texture properties of cakes and through sensory evaluation. Compared to the respective control, incorporation of PPBP in wheat cakes increased the cakes' hardness whereas L* and a* color values decreased. Incorporating GPPBP resulted in better acceptability of wheat flour cakes compared to those containing RPPBP. PPBP up to 10% level can successfully be used to obtain delicious and healthy nutritious fiber-enriched cakes. Valorization of prickly pears processing by-product could be a promising step towards a zero-waste in the juice processing industry. [ABSTRACT FROM AUTHOR]

Context The relationship between carbohydrate quality intake and metabolic syndrome (MetS) is of growing interest. Objective We aimed to assess the association between the adherence to a dietary carbohydrate quality index (CQI) with the occurrence of MetS in a Spanish cohort of working adults. Methods A cross-sectional study was conducted of 2316 middle-aged men, aged 50.9 (SD 3.9) years, with no previous cardiovascular disease, and pertaining to the Aragon Workers' Health Study (AWHS) cohort. Diet was collected with a 136-item semiquantitative food-frequency questionnaire. The CQI (range 4-15) was based on: dietary fiber intake, a low glycemic index, the ratio of whole grains/total grains, and the ratio of solid carbohydrates/total carbohydrates. The higher the CQI, the healthier the diet. MetS was defined by using the harmonized National Cholesterol Education Programme–Adult Treatment Panel III (NCEP-ATP III) definition. The associations across 3-point categories of the CQI and the presence of MetS were examined using logistic regression. Results An inverse and significant association between the CQI and MetS was found. Fully adjusted odds ratios (ORs) for MetS risk among participants in the 10- to 12-point category (second highest CQI category) was 0.64 (95% CI, 0.45-0.94), and in the 13- to 15-point category (highest category) was 0.52 (95% CI, 0.30-0.88), when compared with the 4- to 6-point category (lowest category). Participants with 10 to 12 and 13 to 15 points on the CQI showed a lower risk of hypertriglyceridemia: OR 0.61 (95% CI, 0.46-0.81), and 0.48 (95% CI, 0.32-0.71) respectively. Conclusion Among middle-aged men, a higher adherence to a high-quality carbohydrate diet is associated with a lower prevalence of MetS. Triglyceridemia is the MetS component that contributed the most to this reduced risk. [ABSTRACT FROM AUTHOR]

The improved efficacy and generally favorable safety profile of recently approved and emerging antiobesity medications (AOMs), which result in an average weight reduction of ≥15%, represent significant advancement in the treatment of obesity. This narrative review aims to provide practical evidence‐based recommendations for nutritional assessment, management, and monitoring of patients treated with AOMs. Prior to treatment, clinicians can identify preexisting nutritional risk factors and counsel their patients on recommended intakes of protein, dietary fiber, micronutrients, and fluids. During treatment with AOMs, ongoing monitoring can facilitate early recognition and management of gastrointestinal symptoms or inadequate nutrient or fluid intake. Attention should also be paid to other factors that can impact response to treatment and quality of life, such as physical activity and social and emotional health. In the context of treatment with AOMs, clinicians can play an active role in supporting their patients with obesity to improve their health and well‐being and promote optimal nutritional and medical outcomes.

Arabinoxylan (AX) and resistant starch (RS) are essential components of dietary fiber, that affect the nutritional value, health benefits, and end-use quality of wheat. Fully understanding their genetic basis is crucial for enhancing wheat quality through marker-assisted selection or other means. In this study, a genome-wide association study of AX-related traits i.e., total-arabinoxylan (TAX), water-extractable arabinoxylan (WEAX), and water un-extractable arabinoxylan (WUAX) of whole wheat flour (WWF) and refined wheat flour (RWF), as well as RS content was conducted using 205 elite wheat varieties (lines) with a composite map (24,355 SNPs) constructed with 90 K single nucleotide polymorphism (SNP) arrays. The broad-sense heritability (H2) of RS was 48.50%, whereas that of AX-related traits ranged from 55.66 to 77.23%. A total of 115 loci for RS and AX related traits, comprising 322 marker-trait associations (MTAs), were identified on all 21 chromosomes across four environments, explaining 5.52–12.40% of the phenotypic variance. Among them, 19 stable loci were significant in two or more environments, including one for RWF-TAX, six for RWF-WEAX, four for RWF-WUAX, three for WWF-TAX, two for WWF-WUAX, and three for RS. Furthermore, 17 co-located chromosomal regions related to the measured traits were stably detected in multiple environments. These findings may be used for further research and to improve wheat quality in wheat breeding programs. [ABSTRACT FROM AUTHOR]

In 2018, the authors reported estimates of the number and proportion of cancers attributable to potentially modifiable risk factors in 2014 in the United States. These data are useful for advocating for and informing cancer prevention and control. Herein, based on up‐to‐date relative risk and cancer occurrence data, the authors estimated the proportion and number of invasive cancer cases (excluding nonmelanoma skin cancers) and deaths, overall and for 30 cancer types among adults who were aged 30 years and older in 2019 in the United States, that were attributable to potentially modifiable risk factors. These included cigarette smoking; second‐hand smoke; excess body weight; alcohol consumption; consumption of red and processed meat; low consumption of fruits and vegetables, dietary fiber, and dietary calcium; physical inactivity; ultraviolet radiation; and seven carcinogenic infections. Numbers of cancer cases and deaths were obtained from data sources with complete national coverage, risk factor prevalence estimates from nationally representative surveys, and associated relative risks of cancer from published large‐scale pooled or meta‐analyses. In 2019, an estimated 40.0% (713,340 of 1,781,649) of all incident cancers (excluding nonmelanoma skin cancers) and 44.0% (262,120 of 595,737) of all cancer deaths in adults aged 30 years and older in the United States were attributable to the evaluated risk factors. Cigarette smoking was the leading risk factor contributing to cancer cases and deaths overall (19.3% and 28.5%, respectively), followed by excess body weight (7.6% and 7.3%, respectively), and alcohol consumption (5.4% and 4.1%, respectively). For 19 of 30 evaluated cancer types, more than one half of the cancer cases and deaths were attributable to the potentially modifiable risk factors considered in this study. Lung cancer had the highest number of cancer cases (201,660) and deaths (122,740) attributable to evaluated risk factors, followed by female breast cancer (83,840 cases), skin melanoma (82,710), and colorectal cancer (78,440) for attributable cases and by colorectal (25,800 deaths), liver (14,720), and esophageal (13,600) cancer for attributable deaths. Large numbers of cancer cases and deaths in the United States are attributable to potentially modifiable risk factors, underscoring the potential to substantially reduce the cancer burden through broad and equitable implementation of preventive initiatives.

Background: Mycoprotein is a high-fibre food previously shown to reduce postprandial glucose concentrations when ingested within a mixed-meal. We applied a dual stable isotope tracer approach to determine whether this is due to a reduced rate of appearance of glucose, in participants of ranging BMI. Methods: Twenty-four adults (F = 8, BMI 30 ± 6 kg·m−2) attended 2 trials in a double-blind, randomised, cross-over design. Participants ingested two energy and macronutrient matched milk-based drinks (enriched with 1000 mg [U-13C6] glucose in a subset of 12 participants), containing 50 g glucose and either 0 (CON) or 20 g (MYC) mycoprotein. A primed continuous intravenous infusion of D-[6,6-2H2] glucose determined plasma glucose kinetics over 6 h. Postprandial time-course, and AUC, of glucose and insulin concentration, rate of disappearance (RdT) and appearance of exogenous (RaEx), endogenous (EGP), and total (RaT) plasma glucose were assessed using two- and one-way ANOVA. Results: Drink ingestion increased blood glucose and serum insulin concentrations (P < 0.05) and were comparable between conditions (P > 0.05). Both RaT and RdT were higher with MYC compared with CON over 6 h (mean 6 h glucose appearance and disappearance increased by 5 and 9%, respectively, P < 0.05). RaEx was not affected by MYC ingestion over 6 h (P > 0.05). The mean contribution of EGP to total glucose appearance was 15% greater with MYC, with a trend towards significance (P = 0.05). There was no relationship between BMI and the response to MYC ingestion for any of the variables (P < 0.05). Conclusion: The ingestion of mycoprotein within a mixed-meal impacted postprandial glucose kinetics, but not blood glucose or serum insulin concentrations, in individuals of ranging BMI.

Practical Application Functional dietary fiber ingredient (FDFI) functionality can depend on the fibers’ chemistry, composition, size, botanical origin, and microstructure. However, such claims have never been generalized for a broad range of fibers in one study before. To support these claims, 23 FDFI were characterized based on 11 physicochemical, physical, and compositional property measurements: Water‐ and oil‐holding capacity (WHC and OHC), water absorption and solubility indices (WAI and WSI), flour‐swelling potential (FSP), particle size distribution (D10, D50, and D90 values), and soluble, insoluble, and total dietary fiber content. Multivariate statistical techniques were employed to partition fiber ingredients into functional categories based on these quantitative data, and scanning electron microscopy was used to examine the microstructure of the FDFI. Strong correlations (p < 0.05) were found among many of the physicochemical properties measured, and five categories based on quantitative physicochemical functionality, size, and fiber composition were ultimately found. Distinct patterns emerged between these quantitative partitions and the latent microstructure features and botanical origins of the FDFI. These results can be combined into one intuitive summary of FDFI functionality based on the described quantitative and qualitative observations. Such summaries are useful for ingredient suppliers or product developers with limited resources to infer the general functionality, structure, and food applications utility of their materials based on a subset of the information provided here.The quantitative and qualitative relationships among a range of commercially available functional dietary fiber ingredients are documented. Industry may utilize this information to predict the general functionality of their ingredients based on a subset of the information provided here by assuming that the same relative relationships will exist. This can save time during the ingredient screening process, either for product developers looking to optimize a formulation or for ingredient suppliers doing new ingredient applications testing.

Practical Application This research explored the impact of incorporating various levels of whole soybean pulp (WSP) (10%, 20%, 30%, 40%, and 50%) into wheat flour on the physical and nutritional qualities of steamed bread. In comparison with the traditional steamed bread, the substitution of up to 20% WSP did not significantly alter the specific volume, hardness, and chewiness of the steamed bread. Additionally, the crumb texture of the steamed bread with 20% WSP maintained small and uniform pores, with optimal springiness and cohesiveness. Nutritionally, the substitution of 10%–50% WSP enhanced total dietary fiber, total phenolics, and protein by 9.40%–89.79%, 14.96%–116.31%, and 3.45%–34.36%, respectively. Isoflavones in the steamed bread increased markedly from 22.92 µg/g to a range of 140.12–997.12 µg/g. The expected glycemic index showed a decrease from 90.24 to between 85.85 and 70.75, whereas amino acid scores improved from 59.22 to a range of 64.58–65.08, with lysine (Lys) scores notably increasing from 59.22 to between 64.96 and 88.80. In conclusion, partially replacing wheat flour with WSP is an effective method for enhancing the nutritional profile and addressing the essential amino acid imbalance in steamed bread.This study partially replaced flour with WSP to improve the steamed bread's nutritional quality. The optimal substitution level was determined to be 20% WSP, which improves the bread's nutritional value without significantly impacting its physical qualities. Furthermore, WSP is produced from soaked soybeans through hot water milling. This process simplifies soybean processing, lowers energy consumption and costs, and reduces pollution. It also effectively retains essential nutrients, such as protein, dietary fiber, polyphenols, and soy isoflavones, ensuring the full utilization of soybeans. [ABSTRACT FROM AUTHOR]

Foxtail millet (FM) and green banana (GB) are rich in health-promoting nutrients and bioactive substances, like antioxidants, dietary fibers, and various essential macro and micronutrients. Utilizing GB and FM flour as prebiotics is attributed to their ability to support gut health and offer multiple health benefits. The present study aimed to evaluate the impact of incorporating 10% GB flour (GBF) and different proportions (10–40%) of FM flour (FMF) on the prebiotic potential, antioxidant, nutrient, color, cooking quality, water activity and sensory attributes of noodles. The prebiotic potential, antioxidant, and nutrient of the produced noodles were significantly improved by increasing the levels of FMF. Sensorial evaluation revealed that noodles containing 30% FMF and 10% GBF attained comparable scores to the control sample. Furthermore, the formulated noodles exhibited significantly (p < 0.05) higher levels of protein, essential minerals (such as iron, magnesium, and manganese), dietary fiber (9.37 to 12.71 g/100 g), total phenolic compounds (17.81 to 36.35 mg GA eq./100 g), and total antioxidants (172.57 to 274.94 mg AA eq./100 g) compared to the control. The enriched noodles also demonstrated substantially (p < 0.05) increased antioxidant capacity, as evidenced by enhanced DPPH and FRAP activities, when compared to the control noodles. Overall, the incorporation of 30% FMF and 10% GBF led to a noteworthy improvement in the nutritional and antioxidant qualities of the noodles, as well as the prebiotic potential of the noodles with regard to L. plantarum, L. rhamnosus, and L. acidophilus. The implementation of this enrichment strategy has the potential to confer a multitude of health advantages. [ABSTRACT FROM AUTHOR]

Background: Perinatal depression and anxiety (PDA) is prevalent in new and expectant mothers, affecting millions of women worldwide. Those with a history of mood and anxiety disorders are at the greatest risk of experiencing PDA in a subsequent pregnancy. Current safety concerns with pharmacological treatments have led to a greater need for adjunctive treatment options for PDA. Changes in the composition of the microbiome have been associated with various diseases during pregnancy, and these changes are thought to play some role in perinatal mood disorders. While the relationship between PDA and the microbiome has not been explored, evidence suggests that nutritional interventions with fiber, fish oils, and probiotics may play a favorable role in neuropsychiatric outcomes during and after pregnancy. The primary objective of the present study is to assess the feasibility and acceptability of a combination of nonpharmacological interventions to maintain stability in pregnant women who have a history of depression and/or anxiety. This study will also aim to understand ease of recruitment and protocol adherence in this cohort. Methods: This is a single-centered, partially randomized, placebo-controlled, double-blind feasibility trial. One hundred pregnant women with a history of depression and/or anxiety/PDA will be recruited and randomized into one of four arms, which could include the following: receiving a daily dose of both investigational products and dietary counseling on increasing dietary fiber, receiving a daily dose of both investigational drugs only, receiving fish oil investigational product and placebo, and a control arm with no intervention. The study involves six study visits, all of which can be conducted virtually every 3 months from the time of enrollment. At all study visits, information on diet, mental health, physical activity, and sleep quality will be collected. Additionally, all participants will provide a stool sample at each visit. Discussion: It is anticipated that pregnant women with a history of depression and anxiety will be particularly interested in partaking in this trial, resulting in favorable recruitment rates. Given the positive findings of omega-3 fatty acids (O3FAs) and probiotic supplements on mental health symptoms in nonpregnant adults, we expect a similar trend in PDA symptoms, with a low likelihood of adverse events. This study will build the foundation for larger powered studies to further contribute evidence for the efficacy of this potential preventative treatment option. Trial registration: This trial was registered at ClinicalTrials/gov on October 6, 2023; NCT06074250. Trial Sponsor: The Canadian College of Naturopathic Medicine, 1255 Sheppard Ave E, Toronto, ON M2K 1E2, 416-498-1255. [ABSTRACT FROM AUTHOR]

Bamboo shoot is a healthy food rich in dietary fiber (DF). However, its highly insoluble DF and fibrous texture limit its application in industrially processed foods. To achieve industrial processing of bamboo shoot, cellulase was used to improve the physical characteristics of bamboo shoot DF in this study. After enzymatic hydrolysis, the content of soluble DF (SDF) of bamboo shoot increased by 99.28% (from 5.53% to 11.02%) significantly (p < 0.01). At the same time, the effect of enzymatic‐modified bamboo SDF (EMBSDF) on streptozotocin‐induced type 2 diabetes rats was explored. Results demonstrated that the high dose of EMBSDF (312.8 mg/kg) treated rats showed significant improvements in terms of glucose tolerance and insulin sensitivity (p < 0.01) compared with the diabetes rats. Meantime, it was observed that the levels of glucagon‐like peptide‐1, adiponectin and interleukin‐4 of high dose of EMBSDF compared with diabetes rats were increased (p < 0.01) by 57.79%, 159.13%, and 6.17%, respectively. The tumor necrosis factor‐α, C‐reactive protein, and leptin levels were decreased (p < 0.01) by 62.89%, 31.53%, and 7.84%, respectively. Furthermore, apparent kidney and pancreas histology improvements were found in high‐dose and mid‐dose EMBSDF‐treated diabetes rats. These results indicated that the modified DF significantly improved diabetes. [ABSTRACT FROM AUTHOR]

Simple Summary: Comparative analysis of the gut microbiota in wild grazing (WG) and domestic grazing (DG) yaks reveals distinct differences in bacterial diversity, with WG animals exhibiting a higher diversity than DG animals. Firmicutes dominate both groups, with a greater abundance in the WG type, indicating a stronger fiber-degrading capacity. WG yaks have a higher abundance of Ruminococcaceae and Rikenellaceae families, which are known for their role in fiber degradation, and genus-level differences show a greater presence of fiber-degrading microbes, such as Ruminococcus and Rikenella. In contrast, DG yaks have a higher abundance of Prevotellaceae, Alloprevotella, and Succinivibrio, associated with protein and carbohydrate degradation, reflecting their different dietary habits. These differences in gut microbiota composition suggest that feeding patterns are crucial in shaping the microbial community, influencing yak health and environmental adaptation. The findings presented herein have significant implications for livestock production, highlighting the importance of considering the impact of grazing practices on gut microbiota, and providing valuable insights for developing prebiotics and microbiological agents tailored to specific dietary needs. The gut microbiota is a diverse and complex population, and it has a key role in the host's health and adaptability to the environment. The present study investigated the fecal bacterial community of wild grazing (WG) and domestic grazing (DG) yaks on natural grazing pastures, analyzing the gut microbiota using 16S rRNA sequencing to assess bacterial diversity. A total of 48 yak fecal samples were selected from two different grazing habitats. The DG group had more crude proteins and non-fiber carbohydrates. The WG group had more OM, insoluble dietary fiber such as NDF, ADF, ether extract, and TC. There were 165 and 142 unique operational taxonomic units (OTUs) in the WG and DG groups, respectively. Shannon index analysis revealed a higher bacterial diversity in the WG group than in the DG group. At the phylum level, Firmicutes were the dominant bacterial taxa in both groups. The relative abundance of Firmicutes in the WG group was higher than in the DG group. At the family level, the WG group had a significantly higher abundance of Ruminococcaceae (p < 0.001) and Rikenellaceae (p < 0.001) than the DG group. The abundances of Alloprevotella and Succinivibrio were more pronounced in the DG group than in the WG group at the genus level. This study presents a novel understanding of the bacterial communities of ruminants and their potential applications for livestock production. [ABSTRACT FROM AUTHOR]

The study pertains to preparing value added frozen yoghurt through use of orange peel powder (OPP). The quality aspects of medium-fat (6.0% fat) frozen yoghurt prepared using OPP at three levels (1.5, 2.5, 3.5% as T1, T2 and T3 respectively) was studied. Frozen yoghurt was prepared by freezing blend of fermented yoghurt base with ice cream mix (25:75 w/w); other ingredients were sugar, stabilizer-emulsifier and orange crush. Inclusion of OPP in frozen yoghurt impacted the orange flavour favorably and enriched product with β-carotene and dietary fiber. The control product (TC) was prepared in similar manner, avoiding OPP. As the level of OPP was raised in formulation, there was a marked increase in the protein, carbohydrate, ash and total solids when compared with TC. Presence of OPP markedly affected the acidity, viscosity, overrun and melting resistance of the product; maximum overrun was associated with TC. Product T3 had the maximum acidity and viscosity; T2 had maximum total sensory score. It is recommended to prepare medium-fat frozen yoghurt utilizing 2.5% OPP along with orange crush as flavouring. Such inclusion of peel solids enriched the product with β-carotene and dietary fiber, contributed to stabilization of product and enhanced the products sensory acceptance. [ABSTRACT FROM AUTHOR]

The current trend focuses on reducing food waste, with scientific studies exploring the nutritional value of discarded food components to identify potential health benefits. Beetroot (Beta vulgaris L.) is highly consumed, but its stems and leaves are often discarded. This work aims to characterize the chemical properties and bioactive compounds in beet stems and leaves and assess their applicability in food products. The stems and leaves were subjected to different drying temperatures (50 to 70 °C) to determine the optimal temperature for preserving their bioactive compounds. They are then nutritionally and physiochemically characterized and incorporated into a food matrix. The optimal drying temperature was 60 °C. The leaves and stems contain approximately 30 and 15 g/100 g of protein, 30 and 32 g/100 g of dietary fiber, 4 and 0.45 g/100 g of lipids, and 24 and 25 g/100 g of ash, respectively. Both provide approximately 50% of the amino acid requirements established by the WHO/FAO/UNU and are rich in iron and potassium. The stems presented 53% more betalainic compounds (0.58 mg/g) and a higher nitrate content (359 mg/kg) than did the leaves, which presented a higher polyphenol content. The incorporation of flour from beet stems and leaves into food products is economical, reduces food waste, and enhances nutrition and health. [ABSTRACT FROM AUTHOR]

Dietary fiber incorporation in bread offers potential health benefits but poses challenges due to its impact on dough rheology and bread quality. This study evaluated the effects of pea, cocoa, and apple fiber on wheat-based dough and bread properties using rheological methods (farinograph, alveograph, pasting, and proofing) and baking trials. Substituting flour with fiber at 1%, 5%, or 10% increased water absorption and affected dough development, stability, and extensibility, particularly at high fiber concentrations. Pasting properties showed varying gelatinization behaviors influenced by fiber type and concentration. Principal component analysis (PCA) highlighted the clustering of dough and bread characteristics based on fiber concentration and type. At low fiber concentrations (up to 5% of flour replacement), negative effects were minimal, suggesting no need for comprehensive compositional analysis. However, high fiber concentrations (10%) introduced significant variability and complexity in dough properties. New farinographic parameters (FU4, FU6, FU8, FU10, and FU12) improved the explanatory power of PCA, enhancing the understanding of fiber-rich dough dynamics. The significant alterations in moisture content and texture underscore the intricate relationship between type of fiber, concentration, and dough functionality. Optimizing rheological parameters for fiber-enriched flour is crucial for adapting the bread-making process to produce high-quality bread with desired characteristics and enhanced nutritional benefits.

High-value resources beyond oil extraction for the olive industry need to be developed due to increased olive production. Soluble dietary fibers (SDFs) and olive proteins (OPIs) are important components of olives. However, the commercial production process partially damages OPIs' emulsifying and foaming properties. Thus, the preparation of SDF-OPI complexes would help protect and even improve the emulsifying and foaming properties. The effects of pH and thermal–ultrasonic treatment on the complexation were explored, which showed that the SDF-OPI complexes prepared at pH 5 exhibited superior solubility (p < 0.05). SDF addition noticeably improved OPI thermal stability, emulsifying properties, and foaming properties. Moreover, the complexes prepared by thermal–ultrasonic treatment exhibited higher emulsion stability and lower emulsification activity than those prepared without thermal–ultrasonic treatment. In the acidic system, the electrostatic interaction was considered the main driving factor, assisted by the hydrophobic interaction. Additionally, after thermal–ultrasonic treatment, the covalent binding was observed by infrared spectroscopy. These results revealed the interaction mechanism between SDF and OPI, and the complexes significantly enhanced the functional properties of OPI. This study provides a reference for the high-value utilization of olives, thus broadening their potential uses in the food sector and beyond. [ABSTRACT FROM AUTHOR]

Cocoa bean shells (CBSs) are a byproduct of the chocolate production process, representing the external layer of the cocoa bean. CBSs exhibit many interesting chemical and nutritional characteristics resulting in a very rich content of dietary fiber (DF) and antioxidant compounds such as phenolic acids and flavan-3-ols. The DF fraction of CBSs is notably rich in soluble dietary fibers (SDFs), which may be associated with fermentability and prebiotic properties. The objective of this study was the valorization of CBSs through enzymatic treatments, thereby increasing the solubility of DF and potentially augmenting fermentability. CBSs were treated both raw and defatted. Three sets of carbohydrases were used in order to impact the dietary fiber profile. Cellulase, xylanase, pectinase and their combinations were used to perform enzymatic treatments. The application of cellulase, xylanase and a combination of both enzymes proved effective in achieving a high SDF destructuring of the insoluble dietary fiber (IDF) fraction in both defatted and raw CBSs. Notably, the SDF/IDF ratio was significantly elevated in the enzymatically hydrolyzed samples (1.13–1.33) compared to the untreated CBSs (0.33). Furthermore, the various treatments did not affect the antioxidant activity or the content of the main bioactive compounds. These results provide a foundation for new opportunities in the biovalorization of CBSs through green techniques for a range of potential industrial applications in the food and nutraceutical sectors.

Bread, a staple food consumed worldwide, plays a pivotal role in nutrition. Nevertheless, it is to be underlined that white bread is classified as a high glycemic index food, and its frequent consumption can lead to rapid increases in blood glucose, potentially causing metabolic stress and contributing to insulin resistance and type 2 diabetes. So, there is a growing interest in bread formulations with ingredients that can lower its GI. With this view, bread was formulated, substituting wheat with chickpea flour, red chicory powder, and three distinct types of resistant starch. The results showed the different resistant starches' impacts on the glycemic index reduction. Specifically, chemically modified tapioca RS IV produced a bread formulation with a low predicted glycemic index (pGI < 55). Retrograded starch from tapioca (RS III) allows the bread to reach a pGI value of 55, the upper value for classifying a food as low pGI. The retrograded starch from corn (RS III) allows a decrease in the bread's glycemic index, but the product is still classified as 'high pGI' (>70). Moreover, the addition of by-products rich in polyphenols contributes to a lowering of the pGI. Concerning the technological parameters, the outcome revealed an increase in the moisture content across all the newly formulated samples compared to the control. At the same time, the volume and specific volume showed a decrease. The newly formulated samples exhibited a higher baking loss, particularly when incorporating resistant starch, which increased the hardness and chewiness with decreased cohesiveness. In conclusion, incorporating chickpea flour, red chicory powder, and tapioca-resistant starch (RS III and IV) offers a promising strategy for producing high-fiber bread with a low glycemic index, catering to health-conscious consumers.

Rye grain is a good source of dietary fiber, phenolic compounds, vitamins, and mineral compounds. To prevent the staling process of bread, semi-finished bakery products are subjected to cooling or freezing, and this process is called the postponed baking method. The aim of this study was to examine the influence of rye arabinoxylans differing in molar mass on the properties of rye bread baked using the postponed baking method. The breads were baked from rye flour types 720 and 1150, without and with a 1% share of unmodified or cross-linked rye arabinoxylans (AXs). The molar mass of the unmodified AXs was 432,160 g/mol, while that of the AXs after cross-linking was 1,158,980 g/mol. The results of this study show that the 1% share of AXs significantly increased the water addition to both types of rye flour and dough yield, and this increase was proportional to the molar mass of the AXs used.
