ABSTRACT
Bread is a staple food for billions of households around the world; yet, some of its nutritional value is reduced during the manufacturing process. With this in mind, this work was carried out with the objective of improving the nutritional and functional properties of white bread by using cinnamon in breadmaking in order to contribute to the prevention of certain diseases related to eating habits. Therefore, bread-making trials by incorporating 0%, 0.5%, and 1% of cinnamon powder were carried out. From then on, the breads produced underwent physicochemical, biochemical, and organoleptic analyses. Thus, the results showed that the biochemical composition of the bread containing 1% cinnamon powder and the bread containing 0.5% cinnamon was 11.96 ± 0.02% and 11.22 ± 0.02% for protein, 1.70 ± 0.01% and 1.41 ± 0.07% for fiber, respectively, compared to 10.76 ± 0.014% protein and 1.36 ± 0.17% fiber for the bread without cinnamon. In terms of phytochemical composition, the bread containing 1% cinnamon powder recorded the highest contents of polyphenols, flavonoids, and condensed tannins (551.295 ± 25 µg EAG/g DM, respectively; 53.117 ± 1.36 µg EQ/g DM and 269.837 ± 39.2 µg EC/g DM) compared to the bread containing 0.5% of cinnamon powder and the bread with 1% cinnamon. From the nutritional and phytochemical point of view, the results of this work showed the positive impact of the incorporation of cinnamon powder in wheat flour-based bread with beneficial properties on the health of consumers.
ABSTRACT
Beer is a world-famous beverage that is universally popular. This might be as an effect of its sensory, nutritional, and therapeutic qualities. To date, in Côte d'Ivoire, no study has been carried out focused on the eventual health benefits of industrial beer consumption. In this study, the bioactive compounds (total phenols, total tannins, total flavonoids, total anthocyanins) and corresponding antioxidant activities of two industrial beers from maize and rice from two different breweries were investigated. Results showed that for all phenolic compounds, contents were not statistically different (P > 0.05). However, antioxidant activities (antiradical activity and ferric reducing antioxydant power) were more important in industrial beer from rice (57.57 ± 0.62% and 109.46 ± 0.39 µg/mL ascorbic acid irrespectively) than industrial beer from maize (39.19 ± 1.02% and 103.51 ± 0.62 µg/mL ascorbic acid). Total phenols, total flavonoids, and total anthocyanins were mostly responsible for the antioxidant activities (antiradical activity and ferric reducing antioxydant power) of two beers, with correlation coefficients ranging from r = 0.614 to r = 1. Globally, the two industrial beers were similars but differents from local traditional sorghum beer. Occurrence of phenolic compounds in beers coupled with antioxidant activities shows that beer consumption could have health benefits to condition that beers have a low-alcohol content and light-to-moderate consumption. However, further investigations aims health benefis aspect are necessary.
