Polypeptide powder is made of edible gelatine and vegetable protein by enzyme ferment and spray-dry method. At present, Polypeptide powder has become an essential protein resource of food for Chinese food manufacturers and nourishment experts. Its features: high protein assay 2, it contains polypeptide 3, good taste and solubility ( Adopting the peculiar method, it has no smell, the solubility is 99.9%) 4, It has several kinds of amino acids and good application 6, good security; It is filtered by special method, the assay of pathogenic bacteria can meet the standard. 6, it can help us to digest Ca, Fe and Zn. It can offer two functions: one, it can offer two-way immunoloregulation to the human cells; two, It can offer strong radiation hardening capacity.
