Preparation and application of soybean polypeptides;

Using AN as standards, the optimized conditions of one enzyme hydrolysis, the order of double enzymes hydrolysis and the best condition of low molecular weight polypeptides have been found , with capillary electrophoresis,the molecular weight of soybean polypeptides were determined.

As a new prodution of soybean,soybean polypeptides has specially properties and physiologically function.
