Common Names: reseeding soybean, soybean, wild soybean
Solid-state fermentation of soybeans increases polyphenol content, which can combat Alzheimer's disease. Conditions: 12 days fermentation, 15% inoculation, initial pH 2. Results: 4.98x free polyphenols, 2.38x bound polyphenols, 4.16x total phenols compared to unfermented soybeans. Free polyphenols inhibit acetylcholinesterase by 91.51%.
A study hydrolyzed soy isolate protein with five enzymes and evaluated their effects. The alcalase hydrolysate showed the highest potential in terms of antioxidant and hypoglycemic activities. It also had the greatest biological activities overall.
This study explores using Deep Eutectic Solvents (DES) for extracting flavonoids from soybean and okara. The DES [Ch]Cl: acetic acid with 30% water showed the highest flavonoid content and antioxidant activity. The COSMO-SAC model helped in solvent screening. DES can be a more eco-friendly alternative to traditional solvents.
High temperatures during soybean flowering lead to pollen abortion and fertilization failure. The miR156b-GmSPL2b gene module regulates male fertility and affects gene expression related to pollen development and thermotolerance. This discovery could help breed heat-tolerant soybean varieties.
