(S)-Equol Is there a risk of introducing estrogens through soybean fermentation? Will it introduce other phytoestrogens?

Is there a risk of introducing estrogens through soybean fermentation? Will it introduce other phytoestrogens? Instead of directly fermenting soybeans, daidzein is used as the raw material for fermentation. (1) Neither the fermentation raw materials nor the production process contains animal estrogens, meaning there is no risk of their introduction. (2) Since the raw material

What is the solubility of (S)-equol?

Property Category Details Water Solubility Low; it is a fat-soluble compound. Under weakly alkaline conditions (e.g., pH > 8), it can dissociate to form phenolate ions, leading to an increase in solubility. Solubility in Organic Solvents Freely soluble: Ethanol, methanol, DMSO (dimethyl sulfoxide) Slightly soluble: Ethyl acetate, acetone Practically insoluble: Non-polar solvents such as n-hexane
