Abstract:
Soybean protein isolate processing and production produces a large amount of soybean whey wastewater, which causes environmental pollution and waste of resources directly discharged. Soybean whey wastewater contains soybean whey proteins (SWP), soybean isoflavones, soybean oligosaccharides and other nutrients, of which soybean whey proteins application value is extremely high, rich in trypsin inhibitors,
β-amylase, soybean hemagglutinin, lipoxygenase and other functional factors. Therefore, with regard to the recycling of soy whey proteins, this paper sumerizes the main components in soybean whey proteins, analyses functional properties and research purposes of each component, and sortes out the recovery methods and applications of soy whey proteins. The aim of this paper is to provide a theoretical and technical reference for high value utilisation in industrial production practice.
