This study is aimed at analyzing, evaluating, and optimizing the pectin hydrolysis process to improve the quality of carbonated beverages made from red dragon fruit combined with mint flavor. Red dragon fruit, rich in nutrients and antioxidants, presents challenges in beverage processing due to its high pectin content, which affects clarity and anthocyanin stability. The research investigates the impact of various parameters, including enzyme concentration, hydrolysis time, and temperature, on juice clarity and anthocyanin content. Using a central composite design model, optimal conditions were determined to maximize juice clarity and anthocyanin content. Sensory evaluation during the blending process was also conducted to assess consumer acceptance, focusing on clarity, color, flavor, taste, and total acceptability. The optimum conditions were found to yield maximum clarity (52.763%) and anthocyanin content (224.414 mg C3G/L). Sensory evaluation indicated that 20% dragon fruit juice concentration with 0.12% citric acid, 13°Bx, and 0.30% mint flavor provided the best consumer acceptance. This research demonstrates the potential for producing high‐quality, appealing, and nutritious carbonated beverages from red dragon fruit, contributing to healthier and more sustainable consumption trends.

This research aimed to assess the influence of drying temperature (50, 60 and 70 °C), honey/oat flour ratio (60:40, 50:50 and 40:60) and cocoa contents (5, 6.25 and 7.5 g/100 g) on the physical (color, moisture content, bulk density, flowability (Hausner ratio, Carr index), dispersibility, solubility, and particle size), chemical (total dissolved solids, conductivity, pH, amount of sugar, color, total polyphenolic content, and antioxidant activity), and sensory properties (powder appearance, color, odor; and beverage appearance, color, odor, sweetness, bitterness, taste, texture) of a newly developed cocoa powder mixture in which honey was used as a sweetener and oat flour as a filler. Also, a further aim of this study was to optimize the composition of the mixture based on chemical, physical and sensory properties. Based on the optimization results, the highest total polyphenolic content and antioxidant activity were achieved at 70 °C with a honey/oat ratio of 50% and a cocoa content of 7.5 g. Drying temperature has a significant effect on powder odor and beverage odor, as well as on beverage bitterness, while the honey/oat flour ratio has a significant effect on color, with primarily values L* and a*. The cocoa contents mostly affect total polyphenolic content and antioxidant activity. [ABSTRACT FROM AUTHOR]

Vanilla is one of the most widely used flavors in the food and beverage industry; however, it is thermally unstable and volatile. In this study, microparticles consisting of ternary complexes of vanillin/γ-cyclodextrin/dextran (V/C/D) were prepared, in which vanillin served as a crosslink between the γ-cyclodextrin and dextran. One end of vanillin was inserted into the interior of γ-cyclodextrin through hydrophobic interactions and hydrogen bonding, while the other end was bound to dextran through hydrogen bonding. The encapsulation efficiency of vanillin in the microparticles increased from around 59 to 92% when the mass ratio of dextran in the complexes increased (V/C/D ratio ranging from 1:9:0 to 1:5:4). Moreover, the crystallization peak of vanillin disappeared in complexes with higher dextran contents. The dispersibility of vanillin in cold water (4 ℃) increased as the dextran content in the complexes increased, with the highest value being 15 mg/mL. Encapsulation of vanillin within the microparticles protected it from volatilization during storage, with more than 90% being retained after holding at 60 ℃ for a month, as well as increasing its resistance thermal processing. The release of vanillin during baking (200 ℃, 30 min) could be controlled by altering the composition of the microparticles. Our findings provide a novel strategy for improving the stability and controlling the release of aromas. [ABSTRACT FROM AUTHOR]

AbstractConsumers are increasingly interested in additive-free products with a fresh taste, leading to a growing trend in high pressure processing (HPP) as an alternative to thermal processing. This review explores the impact of HPP on the properties of juices, smoothies, and purees, as well as its practical applications in the food industry. Research findings have explained that HPP is a most promising technology in comparison to thermal processing, in two ways i.e., for ensuring microbial safety and maximum retention of micro and macro nutrients and functional components. HPP preserves natural color and eliminates the need for artificial coloring. The review also emphasizes its potential for enhancing flavor in the beverage industry. The review also discusses how HPP indirectly affects plant enzymes that cause off-flavors and suggests potential hurdle approaches for enzyme inactivation based on research investigations. Scientific studies regarding the improved quality insights on commercially operated high pressure mechanisms concerning nutrient retention have paved the way for upscaling and boosted the market demand for HPP equipment. In future research, the clear focus should be on scientific parameters and sensory attributes related to consumer acceptability and perception for better clarity of the HPP effect on juice and smoothies/purees.

There is a growing market for craft beverages with unique flavors. This study aimed to obtain a palate-pleasing mead derived from Pichia kudriavzevii 4A as a monoculture. Different culture media were evaluated to compare the fermentation kinetics and final products. The crucial factors in the medium were ~200 mg L−1 of yeast assimilable nitrogen and a pH of 3.5–5.0. A panel of judges favored the mead derived from Pichia kudriavzevii 4A (fermented in a medium with honey initially at 23 °Bx) over a commercial sample produced from Saccharomyces cerevisiae, considering its appearance, fruity and floral flavors (provided by esters, aldehydes, and higher alcohols), and balance between sweetness (given by the 82.91 g L−1 of residual sugars) and alcohol. The present mead had an 8.57% v/v ethanol concentration, was elaborated in 28 days, and reached a maximum biomass growth (2.40 g L−1) on the same fermentation day (6) that the minimum level of pH was reached. The biomass growth yield peaked at 24 and 48 h (~0.049 g g−1), while the ethanol yield peaked at 24 h (1.525 ± 0.332 g g−1), in both cases declining thereafter. The Gompertz model adequately describes the kinetics of sugar consumption and the generation of yeast biomass and ethanol. Pathogenic microorganisms, methanol, lead, and arsenic were absent in the mead. Thus, Pichia kudriavzevii 4A produced a safe and quality mead with probable consumer acceptance.

The diversity of alcohol beverage microorganisms is of great significance for improving the brewing process and the quality of alcohol beverage products. During the process of making alcoholic beverages, a group of microorganisms, represented by yeast and lactic acid bacteria, conducts fermentation. These microorganisms have complex synergistic or competitive relationships, and the participation of different microorganisms has a major impact on the fermentation process and the flavor and aroma of the product. Strain selection is one of the key steps. Utilizing scientific breeding technology, the relationship between strains can be managed, the composition of the alcoholic beverage microbial community can be improved, and the quality and flavor of the alcoholic beverage products can be increased. Currently, research on the microbial diversity of alcohol beverages has received extensive attention. However, the selection technology for dominant bacteria in alcohol beverages has not yet been systematically summarized. To breed better-quality alcohol beverage strains and improve the quality and characteristics of wine, this paper introduces the microbial diversity characteristics of the world's three major brewing alcohols: beer, wine, and yellow wine, as well as the breeding technologies of related strains. The application of culture selection technology in the study of microbial diversity of brewed wine was reviewed and analyzed. The strain selection technology and alcohol beverage process should be combined to explore the potential application of a diverse array of alcohol beverage strains, thereby boosting the quality and flavor of the alcohol beverage and driving the sustainable development of the alcoholic beverage industry.

The present study aimed to prepare and evaluate a new probiotic functional beverage, using single‐probiotic and compound probiotic fermentation on okara. Four different forms of fermentation microorganisms used were Lacticaseibacillus rhamnosus S24 (Lr), Lacticaseibacillus paracasei 6244 (Lp), Lactobacillus acidophilus 11,073 (La), and mixed fermentation (Lr + Lp + La). The physicochemical properties, antioxidant activity, flavor change, and storage period of fermented okara beverages with probiotics were investigated. The results showed that different fermentation schemes could significantly improve the physicochemical properties, antioxidant activity, and sensory quality of the okara beverages. The number of viable bacteria in the Lp group (3.53 × 108 CFU/mL), isoflavone content (0.514 μg/mL) were the highest; total phenol and flavonoid content were 3.32 and 5.68 times higher than in the CK group, respectively. DPPH and ABTS+ free radical scavenging rates were increased by 11.32% and 20%, respectively (p <.05). Through SPME/GC–MS analysis, 44 volatile compounds were identified in the Lr + Lp + La groups, mainly as a result of changes in alcohols and aldehydes produced by fermentation metabolism. It enhances the floral and fruity aroma of the okara beverage. All probiotic‐fermented okara beverages can be stored at 4°C for 15 days, with probiotic activity greater than 107 CFU/mL. This study can obtain a probiotic okara beverage rich in soybean isoflavones and with good flavor. Overall, okara can be used to develop functional beverages containing probiotics and contribute to a zero‐waste approach in the food industry. [ABSTRACT FROM AUTHOR]

The aim of this study was to extract vanillic acid from an aqueous solution through reactive extraction. Vanillic acid is utilized in the food and beverage industry as a flavoring agent. Tri-n-butyl phosphate (TBP) served as the reactive extractant, while natural oils like sesame oil and groundnut oil acted as diluents. The recovery of vanillic acid from fermentation broth or wastewater poses challenges due to toxicity concerns. However, employing natural solvents in the extraction process can significantly reduce toxicity. Various parameters, such as extraction efficiency, loading ratio, distribution coefficient, and equilibrium complexation constant, were determined to evaluate the extent of extraction achieved. Groundnut oil emerged as more effective than sesame oil as a diluent, exhibiting a maximum distribution coefficient of 13.31 and an extraction efficiency of 93.01 % at 5.27 mmol L-1 of acid concentration and 40 % v/v of TBP. Additionally, the number of theoretical stages required for the reactive extraction system was calculated, resulting in five stages for groundnut oil and four stages for sesame oil.

Sensory discrimination testing is conducted for many reasons, including—but not limited to—flavor matching initiatives. When conducting these tests on carbonated beverages, there is not an established protocol on the best way to differentiate these multifaceted products. This is in part due to the formulations exhibiting a spectrum of carbonation (CO2) levels, flavors and ingredients. This research conducted tetrad tests at four time points of CO2 dissipation (0, 5, 10, and 15 min) and at two temperatures (refrigerated and ambient) to determine the sample preparation scenarios for which the "high discrimination" and "low discrimination" sample differentiation occurred. Subsequently, a select beverage pair was assessed in the "high discrimination" and the "low discrimination" preparation scenarios using multi‐sip Temporal Check‐All‐That‐Apply (TCATA). The objective of this research was to assess if identifying optimal sample preparations that enhanced sample differentiation from a series of tetrad tests allowed for a more discriminatory TCATA assessment. Results indicated that sample preparation significantly affected the ability to differentiate beverages for select attributes, but the "high discrimination" scenario was not always the more differentiating condition. Future work will aim to increase the knowledge of these interactions with additional carbonated products to further validate and generalize these findings. Practical Applications: Sensory professionals will gain knowledge on how to optimize sample preparation for discovery of scenarios in which carbonated product flavors might be better differentiated.

BACKGROUND: Fermentation is known to enhance the nutritional profile and confer unique flavors to products. However, the resultant effects on stability and physicochemical properties remain unexplored. RESULTS: This study aims to elucidate the influence of fermentation on the stability and organoleptic characteristics of a rice protein beverage stabilized by carboxymethyl cellulose (CMC). The findings revealed that the average aggregate size escalated from 507 to 870 nm, concurrently exhibiting a significant increase in surface potential. The aggregation enhancement was substantiated by evident morphological changes and confocal laser scanning microscopical (CLSM) observations. A negative correlation was discerned between the physical stability of the beverage and fermentation duration. Moreover, flavor analysis of the beverage post a 3 h fermentation period highlighted an increase in aromatic ester compounds, thereby intensifying the aroma. CONCLUSION: The study corroborates that fermentation can detrimentally influence product stability while concurrently improving its flavor profile. By establishing a mix ratio of 10:1 for rice protein and CMC and forming a relatively stable system through electrostatic interaction at a pH of 5.4, a flavorful rice protein beverage can be derived post 3 h‐fermentation process. These findings offer insights into the impact of varying fermentation durations on the stability and flavor of polysaccharide‐based rice protein beverages. © 2023 Society of Chemical Industry.

Chia seeds are rich in polyunsaturated fatty acids and dietary fiber. Cranberry is wealthy in nutrients and phytochemicals that are beneficial for maintaining human health. In this study, chia seeds-cranberry beverage powder (SC-B) were obtained by wet granulation method, and its optimal ratio was 17.4% chia seeds powder, 17.4% cranberry powder, 34.9% maltodextrin, 29.1% xylitol, and 1.2% xanthan gum. The sensory score of the powder was 90.18, the molding rate was 96.05%, the dissolving time was 45.71s, the moisture absorption rate was 4.10%, and the setting volume ratio was 97.48%. The odor of beverage powder was evaluated by electronic nose combined with principal component analysis and Loading analysis before and after dissolution. It was found that the volatile substances of SC-B mainly included broad-methane and inorganic sulfides. The difference in odor was related to whether chia seeds powder is added or not before dissolution, while the difference was decided by cranberry powder after dissolution. The total flavonoids, phenols, and procyanidin contents of SC-B were 2.7, 1.1, and 3.4 mg/g, respectively. The antioxidant capacity to the hydroxyl radical scavenging activity was 97.3% for SC-B at the concentration of 15.0 mg/mL. This study could provide the development and application of chia seeds-cranberry beverage powder. [ABSTRACT FROM AUTHOR]

The internet has become a mainstay of modern‐day life, with people worldwide using social media platforms to discuss ideas and exchange opinions. In recent years, social media platforms have become a data source for research focusing on consumers' natural and spontaneous lexicons. The increased use of social media and virtual meetings means people can exchange ideas, and cultural boundaries have blurred. Thus, this study aims to investigate how culture influences the use of the beverage descriptor "floral" on social media for four different beverages when people share the same language. A social media study was performed, collecting data over 1 year in 13 English‐speaking countries: Australia, Canada, South Africa, the United Kingdom, Singapore, New Zealand, and seven Caribbean Islands. Words associated with four beverages (beer, cocktails, tea, and wine) and floral were filtered on social media mentions. A total of 258,221 mentions were obtained from different types of social media such as Twitter, Instagram, Facebook, and so forth. The mentions were filtered to obtain the frequency of words by country. Each beverage was analyzed separately, and contingency tables were arranged by country and descriptor. A correspondence analysis was performed on each contingency table to identify relative similarities and dissimilarities between the countries in the study. Overall, rose was the most cited floral descriptor, and there was a link between beer and wine descriptions. However, for cocktails and tea, the floral descriptors varied per country. Thus, it suggests that the impact of culture on the use of floral descriptors depends on the beverage being discussed. Practical Applications: The results obtained in this study have relevance for people interested in sensory and specifically in beverage descriptions, as well as those involved in the alcohol industry, particularly those involved in beer and wine, and the non‐alcohol industry (tea). These results can drive the construction of applied and effective marketing strategic plans for the beverage and flavor industry in the areas covered by the study. [ABSTRACT FROM AUTHOR]

BACKGROUND: Sweetened beverages (SBs) have been linked to attention deficit hyperactivity disorder (ADHD), possibly because they contain sugar, caffeine, artificial colors, sweeteners, and preservatives. OBJECTIVE: The goal of this study was to show how SBs affect ADHD and to investigate the potential contribution of the various ingredients in SBs to this effect. METHODS: The study consisted of 239 children, ranging from 6 to 10 years old, divided into two groups: 111 with ADHD, diagnosed by a doctor in the Child and Adolescent Psychiatry Clinic, and 128 in the control group, who were selected from schools. The modified Food Consumption Frequency Questionnaire (FFQ) with 17 sweetened beverages was used in the assessment of beverage consumption. The consumption record was taken together with the brands of the beverages and the label information of the products was examined and the amounts of sugar, caffeine, artificial colors, sweeteners and preservatives in the beverages were calculated. Maximum food additives consumed (mg/day/kg b.w.) values of food additives were calculated according to body weight. To establish the relationship between ADHD and beverage consumption, logistic regression analysis was conducted. RESULTS: Children with ADHD consumed more fruit juice, carbonated beverages, flavored beverages, sugary milk, sugar, caffeine, sodium benzoate and potassium sorbate compared to their healthy peers (p < 0.05). The logistic regression analysis revealed that drinking fruit juice, sugary milk, carbonated beverages, and flavored drinks was significantly associated with ADHD (p < 0.01). CONCLUSION: The consumption of sweetened beverages containing sugar, caffeine, and food additives could potentially effect children's behavior. [ABSTRACT FROM AUTHOR]

Intellectual property pervades all aspects of life. Sustaining intellectual creations is often debatable. The abounding atmosphere of progress and development encompasses other industries as well. Tourism is a major economic driver that promotes social and cultural exchange while directly and indirectly employing millions of people. Destination branding is promoted by tourism. After the 2010 Eyjafjallajökul eruption, Iceland's reputation as a safe tourist destination plummeted. Iceland's government promoted the "Inspired by Iceland" brand to attract tourists. The brand is a symbol, mark, logo, name, word, or sentence used to distinguish one product from another. The paper examines the relationship between intellectual property rights (IPR) and tourism. Geographical indications (GI) have a huge impact on regional tourism. The GI manufacturing process and cultivation tend to attract tourists. Travelers often want to sample regional foods, flavors, aromas, and beverages and buy them directly from consumers, resulting in a tourist influx. The capitalist notion of destination branding is abandoned as the IPR‐based tourism sector is revived. It also promotes the best way to develop the tourism industry while protecting IPRs. The link is also heavily emphasized to promote tourism. Regional development and eco‐tourism policies should be promoted. The tourism industry benefits greatly from protecting indigenous communities and their traditional knowledge. [ABSTRACT FROM AUTHOR]

Aloe vera (Aloe barbadensis Miller) gel is a frequently used ingredient in many food pro-ducts, particularly beverages, due to its reported health benefits. Studies have identified acemannan, a polysaccharide rich in mannose units which are partially or fully acetylated, as the primary bioactive compound in Aloe vera gel. The acemannan content and its degree of acetylation (DA) were measured in 15 different commercial beverages containing Aloe vera at varying concentrations (from 30% to 99.8%) as listed on the label. Other biopolymers such as pectins, hemicelluloses, and cellulose were also evaluated. Flavoured beverages (seven samples labelled as containing from 30% to 77% Aloe vera) presented low levels of acemannan (<30 mg/100 g of fresh sample) and were fully deacetylated in most cases. These samples had high levels of other polymers such as pectins, hemicelluloses, and cellulose, likely due to the addition of fruit juices for flavour. Unflavoured beverages (eight samples, with Aloe vera concentrations above 99% according to their labels) had variable levels of acemannan, with only three containing more than 160 mg/100 g of fresh sample. In fact, four samples had less than 35 mg acemannan/100 g of fresh sample. DA levels in all but one sample were lower than 35%, possibly due to processing techniques such as pasteurization causing degradation and deacetylation of the acemannan polymer. Legislation regarding Aloe vera products is limited, and manufacturers are not required to disclose the presence or quality of bioactive compounds in their products, leaving consumers uncertain about the true properties of the products they purchase.

BACKGROUND: There are sufficient scienctific studies that support the benefit that fermented dairy products produce in those who consume them. Traditionally, cow's milk has been the most commonly used milk but there is a growing interest in the development of new dairy products, substituting cow's milk with milk from other sources, as well as in the use of microorganisms in fermentation to replace artificial preservatives or treatments that may affect the chemical and organoleptic characteristics of the product. For these reasons, the aim of the present work was to understand the behavior of five potential probiotic yeasts during the fermentation of ewe's milk and to consider their potential use as biocontrol agents. RESULTS: Saccharomyces cerevisiae 3 and Hanseniaspora osmophila 1056 provided the most promising kinetic parameters in the different salt, temperature and pH conditions tested in their technological characterization. The profiles of organic acids and volatile compounds after the fermentation period was noteworthy for contributing to the final aroma of the dairy product. Sensory analysis revealed the sour taste of all samples, and S. cerevisiae 3, Lachancea thermotolerans 1039, and H. osmophila 1056 stood out for an accentuated cheese flavor. In addition, all strains showed biocontrol activity; they reduced the mycelium of the mycotoxigenic molds. CONCLUSION: Saccharomyces cerevisiae 3 and H. osmophila 1056 could be inoculated along with bacterial starters to provide a functional fermented beverage with improved flavor. These strains also have an added value as they act as biocontrol agents. © 2022 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

This study employs a multidisciplinary approach to evaluate consumers' perceptions and acceptance of Moringa oleifera Lam. beverages, examining sensory attributes, chemical composition, and bioactivities. High-performance liquid chromatography with diode array detection (HPLC-DAD) analyses revealed significant chemovariation in phenolic compositions among commercial moringa beverages. A soluble moringa powder drink exhibited the greatest concentrations of phenolic and flavonoid compounds, along with powerful antioxidant capacity powers assessed with ABTS•+, DPPH•, FRAP assays, •NO, and H2O2 scavenging activities. However, this sample was the least preferred and presented high Cd levels, exceeding WHO-acceptable values of 0.3 mg/kg. Sensory testing indicated that sweet and floral flavors contributed to beverages being liked, while green, grass, herbal flavors, sour, bitter, and precipitate presence were considered unfavorable sensory attributes. Health claims positively influenced acceptance, particularly among women. Consumers associated feelings of health, wellness, relaxation, and leisure with moringa beverages. During purchase, the most observed information included the ingredient list, health benefits, and type/flavor. These findings emphasize the importance of consumer awareness in reading labels, verifying product origins, and ensuring the absence of contaminants. By understanding consumer preferences and the impact of health claims, producers can better tailor M. oleifera beverages to meet consumer expectations while maintaining safety and quality standards.

The aim of this study was the elaboration of isotonic drinks rich in bioactive compounds and antioxidant activity using organic ingredients and without synthetic additives. Grape juice was used as a natural source of sugars and phenolic compounds, combined with lemon juice and natural flavors from herb and spice extracts. The ingredients were diluted in two types of water with different mineralization, to which three different determined concentrations of salts (sodium chloride and potassium chloride) were added. The beverages had a sugar content ranging from 72.73 ± 0.23 to 78.43 ± 0.06 g/L, total soluble solids between 4.23 ± 0.06 and 4.83 ± 0.29 °Brix, and total acids from 1.75 ± 0.02 to 2.39 ± 0.08 g/L. Generally, antioxidant activity was higher in the beverages flavored with herb and spice extracts, ranging from 3.28 ± 0.01 to 4.27 ± 0.09 µmols Trolox equivalent/mL. Color intensity showed an increase of up to 129.39% in all samples during the storage period, being higher in beverages prepared with high-mineral water and having high pH values. The results of sensory analysis revealed that the flavored beverages had higher values of global perception than the controls. Thus, the functional properties of grape juice have been increased, and these beverages can be alternative natural and healthy products because their formulation is based only on organic and natural ingredients.

The flavor of foods and beverages is generally composed of a mixture of volatile compounds, however not all the molecules that form an aroma are sensorially relevant. The odor-active compounds present in a mixture are different for each subject, both in quantitative and qualitative terms. This means that the ability of the human nose to act as a chemical sensor varies among individuals. In this study, we used the headspace of roasted coffee beans as a complex olfactory stimulus and, by means of the coupled Gas Chromatography-Olfactometry (GC-O) technique, the single components of coffee flavor were separated. Each subject, previously classified for his/her olfactory status (normosmic, hyposmic or anosmic) by means of the Sniffin' Sticks battery (composed of Threshold, Discrimination and Identification subtests), had to identify and evaluate each smelled molecule. The results show that the individual ability to detect individual compounds during the GC-O experiments and the odor intensity reported during the sniffing of pen #10 (the pen of the identification test) containing coffee aroma were related to TDI olfactory status (based on the score obtained from the sum composed of Threshold, Discrimination and Identification scores). We also found that the number of total molecules and of molecules smelling of coffee is linearly related to the TDI olfactory score. Finally, the odor intensity reported when sniffing pen #10 containing coffee aroma is positively correlated with the number of molecules detected and the average intensity reported. In conclusion, our findings show that the human perception of both individual compounds and complex odors is strongly conditioned by the olfactory function of subjects. [ABSTRACT FROM AUTHOR]

The article "What are Caracas residents looking for in a craft beer?" talks about the popularity of craft beer in Venezuela and the consumers' search for trying new flavors and styles of this beverage. Craft beer is characterized by its versatility and the possibility of modifying the recipe according to people's preferences. Consumers of craft beer in Caracas mainly buy it in bars and restaurants, and they are willing to pay more for it due to its higher quality and taste. Additionally, it was found that women value the taste and recommendation of the product more, while men give more importance to the color and alcohol content. Consumers consider craft beer to be more genuine and natural than commercial beer. [Extracted from the article]

"Plant-based beverages," "plant-based milk" and "milk alternatives" are terms commonly used to refer to drinks made from plants, such as legumes, cereals, pseudocereals, and nuts. This study aimed to evaluate the perception and consumption of nut-based beverages by Brazilian consumers. An online questionnaire was prepared with socioeconomic and consumption questions and disseminated in digital media following established ethical standards. The almond beverage was the drink most consumed by the respondents and the Brazil nut beverage was the one that most aroused the most interest among the respondents. Nut beverages were elected as the healthiest, most sustainable, and nutritionally best beverages in comparison with soy beverages and cow's milk. Fruits such as strawberries and bananas were cited as alternatives for flavoring these beverages. Consumers considered the possibility of fully and partially replacing cow's milk and soy drinks with nut beverages. Interest in these along with plant-based milk was not restricted to the vegan segment, and these products were indicated as having strong potential for inclusion in the diets of omnivorous consumers. More studies on buying, purchase intention, acceptance, knowledge, and neophobia among Brazilian consumers are necessary for the development of these beverages, especially with more representative samples of society.

Coffee is an important agricultural product grown worldwide and one of the most consumed beverages in the world. However, its consumption produces a large amount of waste that can be used in industry, benefiting the environment. Thus, the objective of this work was to pyrolyze spent coffee ground generated through the extraction of the coffee beverage (hot aqueous extraction) using two types of coffee, the traditional and the decaffeinated one, and subsequently apply the acid‐base‐neutral extraction technique to produce bio‐oils. This approach aims to isolate nitrogenous compounds, based on the industrial and pharmacological importance of this class of compounds. The acid‐base‐neutral extraction technique used is simple, of low cost, and aims to pre‐concentrate the nitrogenous compounds based on the basic character given by the nitrogen present in these molecules. The analysis of crude bio‐oils (before the fractionation) and the respective fractions was performed by gas chromatography‐Quadrupole‐mass spectrometry. The bio‐oils showed high levels of fatty acids, hydrocarbons, and other oxygen compounds, with only traces of nitrogenated compounds being identified. The acid‐base‐neutral extraction, after solvent recovery, allowed pre‐concentration of these compounds and their identification, highlighting quinolines among the most important compounds and with the greatest biotechnological application.

The relationship between olfactory dysfunction and alcohol intake is unobvious. Chronic alcohol intake results in reduced olfactory acuity and olfactory discrimination and addiction in humans. However, alcohol is a beverage with distinctive odors, which usually works as a cue to induce addictive memories and craving behavior. Whether olfactory impairment increase or decrease alcohol consumption remains an important but unclear issue. In this study, we measured ethanol (EtOH) consumption in the two-bottle choice EtOH drinking test, two bottle choice EtOH/sucrose drinking test and the drinking in the dark (DID) test during the olfactory loss. We also recorded local field potentials (LFPs) from the brain reward system, the ventral tegmental area (VTA), nucleus accumbens (NAc), and piriform cortex (Pir) one and four weeks after the induction of olfactory epithelium lesions using zinc sulfate (ZnSO 4) in mice. The results showed that the EtOH consumption and preference were increased during the period of olfactory dysfunction. 1 week after the olfactory injury, LFP powers in the reward system at low- and high-gamma bands decreased significantly, coherence between the Pir and the reward system was also decrease. 4 weeks after the ZnSO 4 treatment, LFP powers were reversed, but the coherence between VTA and NAc was decreased, indicating lasting effects post-recovery. This study demonstrates that olfactory dysfunction increased EtOH consumption in mice, which was accompanied by decreased LFP power and coherence in the reward system, which suggest that olfactory deficits changed activities in the reward system and could alter reward-seeking behaviors, which provide insights into the neurobiology of alcohol addiction. • Olfactory dysfunction decreased LFP powers in VTA and NAc. • Olfactory dysfunction decreased LFP coherence between VTA and NAc after olfactory recovery. • Olfactory dysfunction increased both ethanol intake and preference in mice. • Ethanol preference was observed not only during the period of olfactory impairment but also endured subsequent to recovery.

Carbonated beverages initiate the swallowing reflex earlier than water and have a shorter pharyngeal transit time. However, the effects of carbonation in thickened beverages of the same flavor on swallowing dynamics have not been reported. Therefore, we investigated the effects of thickened carbonated beverages on swallowing in patients with dysphagia by comparing the swallowing dynamics between thickened carbonated and thickened non-carbonated beverages. We enrolled 38 patients with dysphagia and divided them into two groups. Thickened carbonated and thickened non-carbonated beverages were used. Videoendoscopic swallowing evaluations were performed. Aspiration, penetration, pharyngeal residue, and initiation position of the swallowing reflex were evaluated. The reduction in the amount of residue in both the vallecula (p = 0.007) and pyriform sinus (p = 0.004) was greater after ingestion of thickened carbonated cola than thickened non-carbonated cola. The onset of the swallowing reflex was significantly earlier after ingestion of thickened carbonated cola than thickened non-carbonated cola (p = 0.007). There were no significant differences in the extent of penetration. Thickened carbonated beverages positively affected swallowing compared with thickened non-carbonated beverages. Thus, the use of thickened carbonated beverages may be helpful for patients with dysphagia. [ABSTRACT FROM AUTHOR]

Essential oils (EO) obtained from plants have proven industrial applications in the manufacturing of perfumes and cosmetics, in the production and flavoring of foods and beverages, as therapeutic agents in aromatherapy, and as the active principles or excipients of medicines and pharmaceutics due to their olfactory, physical-chemical, and biological characteristics. On behalf of the new paradigm of a more natural and sustainable lifestyle, EO are rather appealing due to their physical, chemical, and physiological actions in human beings. However, EO are unstable and susceptible to degradation or loss. To tackle this aspect, the encapsulation of EO in microporous structures as zeolites is an attractive solution, since these host materials are cheap and non-toxic to biological environments. This overview provides basic information regarding essential oils, including their recognized benefits and functional properties. Current progress regarding EO encapsulation in zeolite structures is also discussed, highlighting some representative examples of essential oil delivery systems (EODS) based on zeolites for healthcare applications or aromatherapy.

BACKGROUND: After the harvest, green coffee beans are dried on the farm using several methods: the wet process, natural process, pulped natural process, or mechanical demucilaging. This study evaluated how the choice of a specific processing method influenced the volatile organic compounds of the coffee beans, before and after roasting, and the sensory characteristics of the beverage. Coffea arabica beans of two varieties (cv. Mundo Novo and cv. Catuai Vermelho) were subjected to these four processing methods on a single farm in the Cerrado area of Brazil. RESULTS: Analysis by gas chromatography–mass spectrometry headspace solid‐phase microextraction identified 40 volatile organic compounds in green coffee beans and 37 in roasted beans. The main difference between post‐harvest treatments was that naturally processed green beans of both varieties contained a different profile of alcohols, acids, and lactones. In medium‐roasted beans, those differences were not observed. The coffee beverages had similar taste attributes but distinct flavor profiles. Some of the treatments resulted in specialty‐grade coffee, whereas others did not. CONCLUSION: The choice of a specific post‐harvest processing method influences the volatile compounds found in green beans, the final beverage's flavor profile, and the cupping score, which can have a significant impact on the profitability of coffee farms' operations. © 2022 Society of Chemical Industry.
