Soy whey: More than just wastewater from tofu and soy protein isolate industry

摘要

Background: Soy whey is a by-product generated from both tofu and soy protein isolate production. This by-product contains a substantial amount of nutrients consisting of proteins, simple sugars, oligosaccharides, minerals, and soy isoflavones. Soy whey is commonly disposed of into the sewage after it is generated, and this pollutes water bodies.
