| Abstract: | The enzymatic preparation of flavor peptides and amino acids from abalone viscera(Haliotis Discus Hannai Ino) by neutral protease,papain,and trypsin was studied,in which the hydrolysate derived from neutral protease showed the highest hydrolysis degree(DH),peptide yield and the highest flavor amino acid concentration,and the best taste.Single factor test and response surface methodology for neutral protease suggested that the optimum hydrolysis was at 3 000 U/g of enzyme,4% of substrate,46 ℃,pH 7.8 and 3 h,in which the predicted and measured value of DH was 29.81% and 29.98% respectively. |
