Assessment of Sourdough Fermentation Impact on the Antioxidant and Anti-Inflammatory Potential of Pearl Millet from Burkina Faso. Foods 2024; 13:704.

Abstract
Millet, a gluten-free cereal, has received attention for its environmental friendliness and higher protein content than other grains. It represents a staple food in many African countries, where fermentation is traditionally used for preserving food products and preparing different cereal-based products. This study aimed to assess the impact of sourdough fermentation on bioactive compounds and antioxidant and anti-inflammatory properties of pearl millet from Burkina Faso. Phenolic compounds were investigated spectrophotometrically and by HPLC-DAD. The antioxidant activity of unfermented (MF) and fermented (FeMF) millet was evaluated in vitro by spectrophotometric and fluorometric assays and ex vivo on oxidized human erythrocytes for hemolysis inhibition. Finally, the potential anti-inflammatory effect of FeMF and MF was evaluated on human adenocarcinoma cell line (HT-29) exposed to TNF-α inflammatory stimulus. Results revealed significantly higher levels of polyphenols, flavonoids, and in vitro antioxidant activity following millet fermentation. Notable differences in phenolic composition between FeMF and MF are observed, with fermentation facilitating the release of bioactive compounds such as gallic acid, quercetin, and rutin. A dose-dependent protection against oxidative hemolysis was observed in both FeMF- and MF-pretreated erythrocytes. Similarly, pretreatment with FeMF significantly reduced the levels of inflammatory markers in TNF-α-treated cells, with effects comparable to those of MF. Fermentation with sourdough represents a simple and low-cost method to improve the bioactive compounds content and in vitro antioxidant activity of millet flour with promising nutraceutical potential.

Abstract
Barley is one of the world's oldest cereal crops forming an important component of many traditional diets. Barley is rich in a variety of bioactive phytochemicals with potentially health-promoting effects. However, its beneficial nutritional attributes are not being fully realized because of the limited number of foods it is currently utilized in. It is therefore crucial for the food industry to produce novel barley-based foods that are healthy and cater to customers' tastes. This article reviews the nutritional and functional characteristics of barley, with an emphasis on its ability to improve glucose/lipid metabolism. Then, recent trends in barley product development are discussed. Finally, current limitations and future research directions in glucolipid modulation mechanisms and barley bioprocessing are discussed.

Abstract
Phenolics are a group of compounds derived from plants that have displayed potent biological activities and health-promoting effects. Fermentation is one of the most conventional but still prevalent bioprocessing methods in the food industry, with the potential to increase phenolic content and enhance its nutritive value. This review details the biotransformation of different classes of phenolics (hydroxycinnamic and hydroxybenzoic acids, flavonoids, tannins, stilbenoids, lignans, alkylresorcinols) by various microorganisms (lactic acid bacteria, yeast, filamentous fungi) throughout the fermentation process in plant-based foods. Several researchers have commenced the use of metabolic engineering, as in recombinant Saccharomyces cerevisiae yeast and Escherichia coli, to enhance the production of this transformation. The impact of phenolics on the metabolism of microorganisms and fermentation process, although complex, is reviewed for the first time. Moreover, this paper highlights the general effect of fermentation on the food's phenolic content, and its bioaccessibility, bioavailability and bioactivities including antioxidant capacity, anti-cancer, anti-diabetic, anti-inflammation, anti-obesity properties. Phenolics of different classes are converted into compounds that are often more bioactive than the parent compounds, and fermentation generally leads to a higher phenolic content and antioxidant activity in most studies. However, biotransformation of several phenolic classes is less studied due to its low concentration and apparent insignificance to the food system. Therefore, there is potential for application of metabolic engineering to further enhance the content of different phenolic classes and bioactivities in food.

J Food Biochem 2020; 44:e13471. [PMID: 32985001 DOI: 10.1111/jfbc.13471] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 08/14/2020] [Accepted: 08/24/2020] [Indexed: 02/06/2023]
Abstract
Fermented barley (FB) flour by Lactobacillus plantarum is richer in dietary fiber, polyphenols, gamma-aminobutyric acid, and other biologically active ingredients. This study aimed to determine the impacts of fermented barley - wheat flour compound noodle (FBWN) on glucose and fat metabolism in subjects with metabolic syndrome. This was a single-blinded and parallel 10-week clinical trial study. Subjects were randomly assigned into the trial group (FBWN) and whole wheat noodles group (WWN), and were measured on the beginning of week 3 and the ending of week 10. The glucose level at 30 and 60 min was significantly decreased after FBWN intervention. Levels of fasting blood glucose, HbA1c, and TG were all declined after FBWN intervention compared to before in the trial group. Moreover, the fat mass, fat rate, and visceral fat were decreased by 6.48, 7.19, 6.3 kg after FBWN intervention, respectively, while muscle mass and basal metabolic rate rose 7.44 kg and 252.60 kcal. PRACTICAL APPLICATIONS: Many studies have illustrated that the extraction of fermented barley held the activities of anti-obesity, antitumor, and so on. Moreover, this present study evaluated the effects of fermented barley by Lactobacillus plantarum on patients with metabolic syndrome. Results indicated that FB benefits the subjects on improving plasma glycolipids and insulin sensitivity, decreasing visceral fat level, and increasing satiety. The findings showed that the products of FB may be beneficial to dietary manipulations, thus, reducing the burden of patients.
