Preliminary Studies on Oyster Protein / 中国海洋药物

Oyster protein was extracted from fresh oyster using salting-out method. It was determined by Kjeldahl procedure that the protein content was about 38. 6% and free amino-ni-trogen content of total nitrogen was about 21. 6%. Hydrolytic characteristic of oyster protein was analyzed by hydrolytic enzymes. SDS-PAGE results showed there were 4 types of protein zones. And the average molecular weight was 16172, 17633, 43227 and 57909, respectively.
