Oyster was hydrolysed with six kinds of commercial proteinases including pepsin, trypsin, bromelin, papain, 3942 neutral proteinase and Alcalase 2.4L. Three enzymes of better hydrolysis effect were chosen as the target enzymes, taking the α-amino nitrogen in the hydrolysates as the index. The hydrolysis conditions of the three enzymes were investigated by single factor experiment and orthogonal test.

选取胃蛋白酶、胰蛋白酶、菠萝蛋白酶、木瓜蛋白酶、3942中性蛋白酶、Alcalase碱性蛋白酶等对牡蛎进行水解，以水解液中氨基酸态氮的含量为指标，确定了3种水解效果较好的酶：Alcalase碱性蛋白酶、胰蛋白酶和菠萝蛋白酶。

Some of the commercial sources of enzymes that you might want to have on hand would be Bromelain, a protein-digesting enzyme found in many parts of the pineapple.
