Structural properties, antioxidant and immune activities of low molecular weight peptides from soybean dregs (Okara)

In this study, a method for preparing low molecular weight peptides (HPH-VAP) from okara using high-pressure homogenization assisted double enzymes was proposed. In order to explore its advantages, the effects of various methods on protein extraction rate and on the structure, antioxidant and immune...
