Bioactive properties of peptide fractions from Brazilian soy protein hydrolysates: In silico evaluation and experimental evidence

Comparative Assessment of Nutritional Metabolites in Yellow Soybeans at Different Growth Years and Their Antioxidant and α-Glucosidase Inhibition Properties

“…Other soybeans exhibited significant differences over three years (2019 → 2021): Neulchan (62.4 → 57.7 → 56.1%) > Daewon (49.6 → 61.7 → 53.9%) > Saedanbaek (37.6 → 50.9 → 35.8%) > Taekwang (49.7 → 38.0 → 30.4%) (Figure 3D). These findings may be remarkably influenced by the isoflavone contents, as observed in previous studies [2,32,39]. The minor phenolic phytochemicals (phenolic acid, flavonoid, and pterocarpan) in soybean extracts may also be associated with the main portion of the α-glucosidase inhibition [10,40].…”

“…Although recent studies have documented that soybean extracts play an excellent role in α-glucosidase inhibition [2,10,13,39], no reports on the variations of inhibitory capacities against this enzyme in various yellow soybeans have been found. The potential application of α-glucosidase inhibition functions for the development of new excellent soybean cultivars and human health food sources has also not been extensively investigated.…”

Simultaneous production of proteases and antioxidant biopeptides by solid-state fermentation

“…The radical also does not seem to be appropriate to mediate the antioxidant capacity in reaction media that become proteins. Farias et al 60 achieved the characterization of peptides obtained from soybean (a substrate also used in our study) using several methods. The higher molecular weight peptide fractions showed the highest antioxidant activities by three of the methods used, including ABTS, and did not show a good antioxidant activity result for DPPH, which worked better for the lower molecular weight fractions.…”

Anti-Obesity Effect and Signaling Mechanism of Potassium Poly-γ-Glutamate Produced by Bacillus subtilis Chungkookjang in High-Fat Diet-Induced Obese Mice

“…Soybean fermentation can produce bioactive peptides that have a variety of physiological benefits, including the ability to prevent obesity. These peptides may function as inhibitors of pancreatic lipase, an enzyme involved in the digestion and absorption of lipids, resulting in decreased absorption of fat [ 20 , 36 ]. Additionally, they might influence hormones that control hunger and increase fullness, which would lower calorie consumption.…”
