Abstract:
... In this experiment, Gracilariopsis lemaneiformis proteins were hydrolyzed by different proteases (trypsin, pepsin, papain, α-chymotrypsin, alcalase) to prepare antioxidant peptides. Comparing with other hydrolysates, α-chymotrypsin hydrolysates displayed the highest antioxidant activity. The hydrolysis conditions of α-chymotrypsin were further optimized using response surface methodology (RSM), an ...
