Abstract: A kind of nutritious oligo-peptide liquid.containing rich nutrients and oligo-peptides whose average molecular weight is 538 Dalton,was prepared by means of the controlled enzymic hydrolysis technlogy on the snake meat and the correct refining technolgy on the crude product.The optimal technical parameters are as follows:the weight ratio of fresh meat to water is 1 to 2,the added enzymic activity unit is 3600 units per gram meat,the used enzyme kind is the mixture of papain 60 and Asl.398 with the same activities ,the pH value is 6.5~6.8,the reaction temperature is 55 degree centigrade and the reaction time is 6 hours.
