Beschreibung
Zusammenfassung:	The invention relates to the technical field of extraction of sea-buckthorn protein polypeptide, in particular to a preparation method of sea-buckthorn protein polypeptide. The sea-buckthorn polypeptide product with various biological activities is mainly prepared from sea-buckthorn protein as a raw material through protease enzymolysis, centrifugation, concentration and drying. The maximum yield of the sea-buckthorn polypeptide prepared by the method reaches 65.09%. The sea-buckthorn protein is extracted by using an efficient extraction method of alcohol extraction, alkali extraction, acid precipitation and enzymolysis, and the product purity is obviously improved; according to the two-step method of alkaline extraction and enzymatic hydrolysis for extracting the sea-buckthorn protein, the step of enzymolysis is added on the basis of an alkali extraction and acid precipitation method, and protein in separated residues after protein extraction is further extracted, so that the aim of comprehensive utilization
