The aim of this study was to examine the quality characteristics of extruded red Jasmine rice flour (RJF) noodle that had been prepared with hydrocolloids, namely guar gum (GG), carboxymethyl cellulose (CMC), and xanthan gum (XG) at the concentrations of 0.0 (control sample), 0.2, and 0.4% (w/w), respectively. The use of hydrocolloids had no effect on total phenolic contents, antioxidant properties (DPPH, ABTS, and FRAP), color, and X-ray diffraction patterns (p > 0.05). In contrast, the hydrocolloids tended to increase the expansion ration of the noodle. GG and CMC improved cooking, textural, and sensory properties. Ultimately, 0.2%-GG showed the lowest cooking loss (5.07%) when compared with others. Moreover, it also provided the noodle with better textural properties such as tensile strength, extensibility, hardness, cohesiveness, and chewiness (p < 0.05). For these reasons, the highest acceptability (6.75) for the noodle was achieved with GG02. XG resulted in lower overall acceptability (5.05), particularly the 0.4%-XG recipe (p < 0.05). Thus, usage of 0.2%-GG was the best option for improving the qualities of extruded RJF noodle. XG was deemed ineffective for improving the noodle.

In this study, physical (cooking time, water ab-sorption, cooking loss and color), chemical (proximate composition, pH, total phe-nolic content, mineral mat-ter (Ca, K, Fe, Mg and Zn)), textural (hardness and adhe-siveness) and sensory (col-or, taste, flavor, appearance, hardness, adhesiveness and overall acceptability) attrib-utes were determined in dif-ferent types of noodles pro-duced from siyez wheat flour, kale powder and chia seed mucilage. Results were statistically evaluated using SAS software. The optimal cooking time for the noo-dles were 20 min and cook-ing loss varied between 8.36-12.22%. Kale powder and chia mucilage addition decreased L* and a* values of the noodles. Ash, crude fiber, mineral matter and total phenolic contents of the noodles were higher and fat contents of the noodles were lower than the control sample. Hardness and adhe-siveness of the noodles were decreased by addition of the kale powder at 10%. The noodles with higher hard-ness and lower adhesiveness were preferred by the panel-ists in sensory evaluation. Increasing the kale powder level in the noodle formula-tion from 5% to 10% result-ed in higher color scores. However, the control sam-ple was the most preferred sample in terms of taste.

The effect of the addition of three types of tropical edible seaweeds, Kappaphycus alvarezii (KA), Sargassum polycystum (SP), and Caulerpa lentilifira (CL), on sausages were studied. Nine sausage formulations with three levels of inclusion (2%, 4%, and 6%) of each seaweed were prepared, analysed, and compared with the control sample (without seaweed) in terms of their physicochemical properties, total phenolic content, and lipid oxidation. The modified sausages had low moisture and fat content (p < 0.05) but high ash and dietary fiber content (p < 0.05) compared to the control sausage. The addition of seaweed powder changed the texture of the sausages, mainly its hardness and chewiness (p < 0.05), but no significant difference in cohesiveness and springiness was found (p < 0.05). The modified sausages were shown to have high water holding capacities and cooking yields. The different types of seaweed modified the colour of the chicken sausages differently. In general, the L* (brightness) and b* (yellowness) values was low for all sausage samples containing seaweed powder (p < 0.05), while the a* (redness) value increased with the addition of the KA and SP seaweed powder but decreased for the sausage sample with added CL seaweed powder (p < 0.05). Moreover, the modified sausages have higher total phenolic contents and high antioxidant capacities, which contributed to slowing the oxidation of lipid in sausages during storage (p < 0.05). Sensory evaluation showed that the panellists found up to 4% of KA and 2% of SP to be acceptable. Overall, the seaweeds, especially KA and SP, could potentially be developed as excellent additives for the manufacture of highly technological high-quality meat products.

Our group showed that crude ethanol (CE) and butanol (BUT) extracts ofCapsicum baccatumpresented anti-inflammatory and antioxidant properties. Furthermore, the flavonoid and total phenolic contents were positively correlated with both of these properties observed forC. baccatumextracts. The present study demonstrated that 60 days of oral administration of CE and BUT (200 mg/kg) in mice did not cause significant differences in the following parameters evaluated: hematological profile, body weight and relative weight of visceral organs, systemic lipid profile, glucose homeostasis (GTT), kidney and hepatic biochemical markers, and spontaneous locomotion and anxiety-like behavior. Altogether, these results indicate for the first time that the long-term oral administration ofC. baccatumextracts does not affect specific aspects of CF1 mice physiology, suggesting their safety, building up the venue to test their efficacy in animal models underlying persistent activation of oxidative and inflammatory pathways.

The polyphenolic contents and the antioxidant activity of the skins and pulps of different grape cultivars were estimated using HPLC and DPPH antioxidant assay, respectively. The phenolics and flavonoids identified were quercetin, kaempferol, caffeic acid, p-coumaric acid, cinnamic acid, and (−)-epicatechin. The total phenolic contents were found to be the highest in the grape skin of Flouxa (>400 mg/100 g), followed by Campbell Early and Tamnara (>300 mg/100 g), and then by Red Globe and Ruby Seedless (>250 mg/100 g), and the total phenolic content was the lowest in Italia and Delaware (<60 mg/100 g). The antioxidant activities of the grape extracts varied from 12.5% (Ruby Seedless) to 60.2% (Hongiseul) for skins, whereas the antioxidant activities of the grape extracts varied from 35.4% (Campbell Early) to 84.5% (Hongiseul) for pulps. The grape pulps have stronger antioxidant activities than those of the grape skins. Our results suggest that the phenolic and flavonoid contents in extracts of grape skins and pulps showed statistically significant correlations with the free radical scavenging activity.

Hom Nil (Oryza sativa), a Thai black rice, contains polyphenolic compounds which have antioxidant properties. The objective of this study was to investigate physicochemical properties of Hom Nil rice flour (HN) and its application in gluten free bread by using Hom Mali 105 rice flour (HM) as the reference. The results demonstrated that HN flour had significantly higher average particle sizes (150 ± 0.58 μm), whereas the content of amylose (17.6 ± 0.2%) was lower than HM flour (particle sizes = 140 ± 0.58 μm; amylose content = 21.3 ± 0.6%). Furthermore, HN contained higher total phenolic compounds (TPC) (2.68 ± 0.2 mg GAE/g flour), total anthocyanins (293 ± 30 mg cyanidin-3-glucoside/g flour), and the ferric reducing antioxidant power (FRAP) (73.5 ± 1.5 mM FeSO4/g) than HM flour (TPC = 0.15 mg GAE/g flour and FRAP = 2.24 mM FeSO4/g flour). In thermal properties, the onset temperature (To), the peak temperature (Tp) and the conclusion (Tc) temperature of HN flour were similar to the values of HM flour. However, HN flour had lower enthalpy change (ΔH) than HM flour. The results showed that HN flour had lower swelling power and higher solubility than HM flour at the temperature between 55 °C and 95 °C. In pasting properties, HN flour also showed lower peak, trough and breakdown viscosity than HM flour. In addition, the bread samples prepared by HN flour had higher value of hardness and lower value of cohesiveness than the bread prepared from HM flour. Taken together, the findings suggest that HN flour could be used as an alternative gluten-free ingredient for bread product.

This study aims to develop nutraceutical beverages containing food processing by-products in their formulation, and determine the opinion of consumers. This is done by testing whether they know that the main ingredients of the product are by-products, performing an overall acceptability test of the developed beverages, and evaluating the emotions induced by the newly developed beverages for consumers. The main ingredients used for the preparation of added-value beverages were fermented milk permeate (containing galactooligosaccharides), extruded and fermented wheat bran (WB) (containing ≥6.0 log10 CFU g−1 viable antimicrobial properties showing lactic acid bacteria (LAB) strains), and different fruit/berry by-products (FBB) (as a source of compounds showing antioxidant properties). The definition of the quantities of bioactive ingredients was based on the overall acceptability of the prepared beverages, as well as on emotions induced in consumers by the tested beverages. Functional properties of the developed beverages were proofed by the evaluation of their antimicrobial and antioxidant properties, as well as viable LAB count during storage. Desirable changes in extruded and fermented WB were obtained: Fermentation reduced sugar concentration and pH in samples with predominant lactic acid isomer L(+). In addition, the viable LAB count in the substrate was higher than 6.0 log10 CFU g−1, and no enterobacteria remained. By comparing the overall acceptability of the beverages enriched with WB, the highest overall acceptability was shown for the samples prepared with 10 g of the extruded and fermented WB (7.9 points). FBB showed desirable antimicrobial activity: Shepherd inhibited—2, sea buckthorn—3, blueberries—5, and raspberries—7 pathogens from the 10 tested. Comparing different beverage groups prepared with different types of FBB, in most cases (except sea buckthorn), by increasing FBB content the beverages overall acceptability was increased, and the highest score (on average, 9.5 points) was obtained for the samples prepared with 5.0 and 7.5 g of blueberries FBB. Moreover, a very strong positive correlation (r = 0.8525) was found between overall acceptability and emotion “happy” induced in consumers by the prepared beverages enriched with extruded and fermented WB and FBB. By comparing the samples prepared with the addition of WB with samples prepared with WB and FBB, it was observed that most FBB increased total phenolic compounds (TPC) content (on average, by 9.0%), except in the case of samples prepared with sea buckthorn. A very high positive correlation (r = 0.9919) was established between TPC and antioxidant activity. Finally, it can be stated that the newly developed nutraceutical beverages were acceptable for consumers, induced positive emotions, and possessed desirable antimicrobial and antioxidant properties, while being prepared in a sustainable and environmentally friendly manner.

In Tunisia, despite the large annual production and the numerous citrus varieties under cultivation, citrus processing industries lack product diversity. Products based on dietary properties are a new trend aiming to develop innovative foods and to meet the requirements of the new customer class. In the present study, formulations of reduced sugar jelly products using antioxidant rich-fruit, citrus, were carried out. The effects of citrus juices on the jelly’s antioxidant properties, colour, consistency, and sensory evaluation were also investigated. Results showed that all citrus jellies maintain their antioxidant activity, correlated with phenolic content presence. In fact, total phenolic contents ranged between 123.16 and 192.76 mg GAE/100 g, while flavonoid content varied between 1.54 and 9.06 mg QE/100 g for grapefruit jelly and blood orange jelly, respectively. Results illustrated that antioxidant activity varies according to the variety. A sensory evaluation employing hedonic scale technique exhibited satisfactory acceptance of the reduced sugar blood orange and blond maltase jellies. These results highlight and promote the potential use of these citrus varieties in jelly industry as they present a rich source of phenolic compounds and may generate numerous phytochemicals with potential health promoting properties.

Aims: The aim of the work is to investigate the effect of soybean and Plantain flour fortification on the nutritional, microbial and sensory qualities of rice flour paste (Tuwo) fortified with soy and plantain flour blends. Methodology: White rice was cleansed, sorted and soaked in water for 12hrs and dried at 60OC for 12hrs.  White rice was fortified with soybean and plantain flour at 10, 15, 20, 25% respectively while 100% white rice flour serve as the control. Nutrient, microbial and sensory qualities of the samples were determined using standard methods. Results: There were significant differences (p≤.05) and increase in values of all the nutritional properties with increase in substitution of soy-plantain flour. The protein content ranges from (2.19 – 21.46%), Fat content (1.67 – 18.51%), Fiber (0.68 – 6.78%), Ash content (1.37 - 2.26%), Moisture content (10.16 – 12.47%) of the blends respectively, while the carbohydrate contents of the blends was significantly lower to that of the control sample. The mineral content increased where the abundant mineral was potassium (29.22 – 45.57 mg/100g) and zinc (2.66 – 3.34 mg/100g) been the least mineral element. The microbial analysis shows a lower microbial counts of prepared tuwo samples, which makes it safe for consumption. Mean total viable count range from 1.10 to 3.50 x102 cfu/g, Staphylococcus count range from 0.00 to 1.03 x102 cfu/g. fungi count range from 0.00 to 0.60  102 cfu/g with no growh of salmonella from all the samples respectively. The sensory evaluation result shows that the sample from whole rice was highly rated but sample B with 80% rice flour, 10% soy flour and 10% plantain flour has the highest preference in terms of taste, colour, aroma, texture, smoothness and overall acceptability. Conclusion: This fortification highly improve its nutrient contents and slightly improves microbial and organoleptic properties of rice tuwo, which can serve as alternative protein supplement.
