The invention discloses a novel method for preparing high-activity collagen peptide from cow placentae. The method comprises the following steps: maintaining mammal placentae at a low temperature, chopping, soaking and rinsing, grinding into pulp, extracting, centrifuging, performing enzymolysis, filtering, desalting, concentrating and freeze-drying. The method disclosed by the invention has the characteristics that the extraction effect is good, the high-activity collagen peptide prepared by using the method is high in purity, the activity is high, a product containing the collagen peptide is easy to absorb, and the like. The method can be simply operated, is low in production cost and is applicable to on-scale industrialization production, and the purpose that the high-activity collagen peptide is efficiently prepared from cow placentae is achieved. |
