Method for extracting hippophae rhamnoides seed protein from hippophae rhamnoides seed meal

The invention relates to the technical field of extraction of hippophae rhamnoides seed protein, in particular to a method for extracting hippophae rhamnoides seed protein from hippophae rhamnoides seed meal. The hippophae rhamnoides seed meal is mainly used as a research object; high-quality hippophae rhamnoides seed protein is prepared by an efficient extraction method of alcohol extraction, alkali extraction, acid precipitation and enzymolysis, so that the taste, solubility and the like are improved, wherein the product purity is obviously improved by utilizing an alkali extraction and acid precipitation method; the step of enzymolysis is added on the basis of the alkali extraction and acid precipitation method for extracting the hippophae rhamnoides protein by utilizing an alkali-enzyme two-step method; the protein in the separated residues after the protein is extracted is further extracted, so that the purpose of comprehensive utilization is achieved; furthermore, the extraction rate of the hippophae rh
