The importance of functional foods, Except for their nutritional role, is due to providing physiological benefits or reducing the risk of chronic diseases. Cake is a popular product among consumer meals. Therefore, reducing the amount of sucrose in the cake by making it functional with citrus fiber and essential oils is an effective step in the grain industry. The breakfast cakes containing isomalt, orange fiber and cinnamon essential oil were prepared in 8 groups. The physicochemical, color and sensory properties of breakfast cakes were investigated. The results showed that the pH of the prepared cakes was not significantly different from the control group (p>0.05). While the variables of orange fiber, isomalt, and cinnamon essential oil were effective in maintaining the moisture content of cakes (p<0.05). As expected, the fiber content of breakfast cakes increased with the addition of orange fiber (p<0.05). The fat and protein content of the treatments was lower than the control sample The protein of the treatments did not have a significant difference (p>0.05); however, they showed a significant difference with the control treatment(p<0.05), but their ash was significantly higher than these groups (p<0.05). A significant decrease in sucrose content was reported by replacing part of it by isomalt (p<0.05). Improvement in baking volume and weight loss of breakfast cakes containing orange fiber, isomalt, and cinnamon essence was also reported (p<0.05). Examining the color index of breakfast cakes showed an increase in the L* and b* values while the a* value decreased (p<0.05). Sensory evaluation showed an increase in the acceptability of cakes containing orange fiber, isomalt, and cinnamon essential oil compared to the control sample. Considering the total results, the breakfast cake containing 2% orange fiber, 2% isomalt, and 0.1% cinnamon essence was introduced as the best treatment in this research. [ABSTRACT FROM AUTHOR]

The aim of the current study was to investigate the suitability of Ziziphora tenuior essential oil (ZEO) as a preservative. For this purpose, the effect of free and microencapsulated ZEO, combined with orange fiber, was determined on the chemical and microbial qualities of cooked beef sausage. In this study, modified starch was used for encapsulation of essential oil, and subsequently, 0.5% ZEO and 1% orange fiber were used for preparing cooked beef sausages during 60 days of storage at 4°C. To assess the microbial quality of samples, total viable count (TVC), psychrophilic count (PSY), and lactic acid bacteria (LAB) were analyzed. Furthermore, peroxide value (PV) and thiobarbituric acid reactive substances (TBARS) were tested to examine lipid oxidation. The most components of ZEO were pulegone (47.12%), isomenthone (14.57%), and 1,8‐cineole (12.84%) according to GC–MS analysis. The reducing power, DPPH radical scavenging activity, MIC, and MBC of ZEO were 16.44 (EC50), 8.36 (IC50), 0.625–2.5, and 1.25–5 mg/ml, respectively. Moreover, sausage containing 0.5% microencapsulated ZEO in combination with 1% orange fiber showed the best results with the following values (p ≤.05): TVC (3.69 log CFU/g), PSY (3.51 log CFU/g), LAB (3.1 log CFU/g), PV (10.41 meq/kg lipid), and TBARS (3.1 mg MDA/kg). This is due to the antimicrobial and antioxidant properties of microencapsulated essential oil. Therefore, the results of the present study can be applied in the meat industries as a new natural preservation method. [ABSTRACT FROM AUTHOR]

In this study, the effect of orange fiber (dietary fiber source) addition on gluten free batters from rice flour and buckwheat flour rheological properties was investigated by using LAOS method. The effect of different amount dietary fiber on some quality parameters (textural properties, specific volume) of gluten free cakes were also investigated. Gluten-free cake batters were formulated by replacing buckwheat flour with orange fiber at different levels (0%, 4%, 8%, 12% and 16%). Results showed an increase in storage (G') and loss (G") moduli values with the addition of dietary fiber in the gluten free batter. All gluten-free cake batter samples showed linear viscoelastic properties at small strain amplitudes but rheological properties enters the non-linear region by increasing strain amplitude. Increaing the dietary fiber amount caused to increase in specific volume (P <0.05) of gluten free cakes and decrease in hardness value (P <0.05) of cakes. [ABSTRACT FROM AUTHOR]

In this study, sucuk samples with different orange fiber (0%, 2% and 4%) and fat (sheep tail fat) levels (10%, 15% and 20%) were produced and textural parameters were investigated during ripening time. Use of orange fiber significantly affected hardness, chewiness, gumminess and resilience parameters in all groups (P<0.01). The highest hardness score was detected in samples containing 4% orange fiber. In contrast, no statistically significant effect of fat usage was observed on hardness (P>0.05). While textural parameters, adhesiveness, springiness, chewiness, gumminess and resilience, were affected (P<0.01) by fat level, cohesiveness was not significantly affected by fat level (P>0.05). However, ripening time was the most effective factor on all textural parameters (P<0.01). While a permanent increase was observed in hardness, adhesiveness, gumminess and chewiness values of all samples during ripening the highest value (increase) was determined in hardness.

In this study, the effects of fat (10, 15 and 20%) and orange fiber (0, 2 and 4%) levels on volatile compounds of sucuk (Turkish dry-fermented sausage) were investigated. The volatile compound profile of sucuk samples was analyzed by gas chromatography/mass spectrometry (GC-MS) by using a solid phase microextraction (SPME). 75 volatile compounds were identified in the sucuk samples. The volatile compounds identified were 11 aldehydes, 7 aliphatic hydrocarbons, 2 acids, 10 esters, 1 furan, 5 alcohols, 8 aromatic hydrocarbons, 6 ketones, 6 sulphur compounds, and 19 terpenes. It was determined that the use of orange fiber had significant (P<0.05) effects on a few volatile compounds (allyl methyl sulfide, copaene and caryophyllene). Alpha-thujene was significantly affected by fat level (P<0.05). Fat level also showed very significant effect on p-xylene and allyl methyl sulfide (P<0.01). As result, orange fiber and fat level had no significant effects on volatile profile of sucuk samples. [ABSTRACT FROM AUTHOR]

The demand for healthier foods by consumers has driven the food industry to develop foods that contain less fat, however without altering the sensory characteristics and nutritional products. The ice cream industry is one that uses more fat in their formulations, containing on average 10% of this ingredient. An alternative to the replacement of fat is the fiber of citrus fruits, which has been used successfully by reducing the fat content in the meat industry, for example. Thus, the objective of this study was to evaluate the sensory characteristics and physical-chemical ice cream made with fiber commercial bitter orange peel as a substitute for fat. Two formulations with different concentrations of orange fiber (F1 and F2 with 0.74% to 1.10% fiber) and a control formulation (with fat) were used. The two formulations were found consistent with the literature values for the chemical composition of ice cream. Regarding the energy value of ice cream was observed reduction of more than 25%, indicating that the product may claim "light". For the fiber content of the cream, the values were 1.4% of F1 and F2, 2.0%, can consider ice cream formulation F2 as a source of fiber. The attributes of color, odor and texture didn't differ between samples. Already flavor, after taste and overall acceptability differences between samples obtained with fiber and control. Ice cream prepared with fiber obtained orange peel acceptance rates of 78% [ABSTRACT FROM AUTHOR]

Abstract: Combined use of Lactobacillus casei CECT 475 and orange fiber for the production of Spanish non-fermented dry-cured sausage (Longaniza de Pascua) was studied. Quality and safety characteristics of four “Longaniza de Pascua” types (control, 1% fiber, L. casei and 1% fiber + L. casei) were evaluated during 8 days of dry-curing. At the end of the dry-curing process pH of all types of sausages was higher than pH 5.3 and water activity was below Aw 0.91. The incorporation of 1% orange fiber favored the growth of lactic acid bacteria. The addition of orange fiber and L. casei CECT 475 accelerated the decline in pH and the release of organic acids and glycerol. Sausages containing both orange fiber and L. casei CECT 475 obtained the best sensory scores and provided the best guarantees of food safety, low pH and water activity, decreased counts of Enterobacteria and reduced residual nitrite compared to the other type of sausages.

Abstract: The effects of orange fiber and fat levels on the physical, chemical and microbiological properties of sucuk (Turkish dry-fermented sausage) were investigated. Different levels of orange fiber (0, 2 and 4%) were added to sucuk batters with different levels of fat (10, 15 and 20%). Sucuk samples were analyzed during ripening. Lactic acid bacteria, Micrococcus/Staphylococcus and pH value were effected very significantly by orange fiber. Orange fiber caused a decrease in residual nitrite levels and an increase in the TBARS values. L ∗ and b ∗ values of sucuk samples increased with the use of fiber. Fiber use also decreased the cooking loss. No statistically significant difference was found between control and 2% fiber groups in terms of texture, color, odor taste and general acceptability scores. While fat levels had significant effects on cooking loss, taste and L ∗ values, ripening time effected all analyzed parameters. [Copyright &y& Elsevier]

The aim of this study is to investigate the effect of dietary fiber enrichment on non-linear viscoelastic behavior of gluten-free cake batters by using Large Amplitude Oscillatory Shear (LAOS) analysis. Textural properties and specific volume of gluten-free cakes were also determined to investigate the possible correlations with LAOS parameters. Gluten-free cake batters were formulated by replacing buckwheat flour with two different dietary fiber sources, namely orange fiber (OF) and orange pomace powder (OPP) at five different levels (0%, 4%, %8, %12 and 16%). All gluten-free cake batter samples exhibited linear viscoelastic properties at small strain amplitudes but rheological properties enters the non-linear region by increasing strain amplitude. The Lissajous-Bowditch curves revealed that stored energy increased by increasing dietary fiber amount and gluten-free cake batters became more elastic in the non-linear region. The normalized elastic Chebyshev coeffients (e 3 /e 1) indicated the strain hardening behavior of cake batters at small strain amplitudes shifted to strain softening in the non-linear region. The e 3 /e 1 and v 3 /v 1 ratios as a function of strain amplitude indicated that non-linearity is more pronounced in the elastic component compared to the viscous component. The S and T values calculated at 50% strain amplitude showed strong correlation with water retention capacity, hardness and specific volume of gluten-free cakes enriched with OF whereas softer correlations were obtained for the OPP-containing ones due to elastic instability of the batters. Principal component (PCA) and hierarchical cluster analysis (HCA) were performed to provide basic graphical comparison of the differences/similarities between non-linear rheological properties of gluten-free cake batters by considering LAOS parameters. The viscoelastic properties of the cake batters containing 16% OPP were found to be suitable for high gas retention capacity since the highest cake specific volume was obtained. • Effect of different dietary fiber addition on rheological properties of cake batters was investigated. • Rheological characterization of gluten-free cake batters were carried out by LAOS analysis. • Quality properties of cakes were also determined to investigate correlation with LAOS data.
