Slit divergent ultrasound pretreatment assisted watermelon seed protein enzymolysis and the antioxidant activity of its hydrolysates in vitro and in vivo

Watermelon seed, a watermelon processing industry by-product, is a good protein source for the preparation of antioxidant peptides due to its high protein content, low cost, special amino acid composition. Antioxidant hydrolysates obtained from watermelon seed protein (WSP) after slit divergent ultrasound (SDU) treatment were studied. The stepwise multiple linear regression model verified that the reducing power of watermelon seed protein...
