The invention relates to a seabuckthorn oligopeptide powder and a preparation method and application thereof. The content of the oligopeptide powder peptide is more than 70wt%, and the molecular weight of more than 75% of the seabuckthorn peptide is less than 700 Dalton. The method includes extracting seabuckthorn protein by using a high-efficiency countercurrent extraction method, filtering and enzymatic hydrolysis, then efficiently separating and purifying the protease hydrolyzate through membrane equipment, and finally concentrating and spraying to obtain oligopeptide powder. The method of the invention has the advantages of simple operation, high yield and low cost, stable product quality, green process and environmental protection, and is suitable for large-scale production. |
