Metabolic tracking of isoflavones in soybean products and biosamples from healthy adults after fermented soybean consumption.

Fermentation may enhance the nutritional properties of foods by increasing metabolite bioactivity or bioavailability. This study explored the effect of fermentation on isoflavone bioavailability and metabolism. Isoflavone metabolites were tracked in foods and biospecimens of healthy adults after fermented soybean (FS) or non-fermented soybean (NFS) consumption in a randomized, controlled, crossover intervention study.

Optimal conditions for the encapsulation of Weissella cibaria JW15 using alginate and chicory root and evaluation of capsule stability in a simulated gastrointestinal system.
