The invention discloses a full nutritional silkworm pupa peptide functional foodstuff, a preparation method thereof and a novel method for juice extraction and peeling of silkworm pupas. Protamex composite protease and Flavourzyme flavor protease are adopted for zymohydrolysis step by step, so that the efficiency and the polypeptide yield are high; the pH value is not required to be adjusted, so that chemical residue is avoided; and raw materials are subjected to sterilized treatment, so that the product is safe and sanitary; the method for juice extraction and peeling is simple and convenient, has high efficiency, and is complete in separation of slag crust; and more than 90 percent of proteins in the product are converted into micromolecular peptide, and the micromolecular peptide with more than 80 percent of molecular weight is distributed between 100 and 4,000 Dalts. The product comprises the following compositions: 46 to 55 percent of polypeptide, 5 to 10 percent of free amono acid, 22 to 33 percent of fat, 2 to 7 percent of carbohydrate and 3 to 8 percent of ash, and contains various mineral matters, microelements and vitamins. The product has the efficacies of reducing blood lipid, reducing blood pressure, preventing cardiovascular and cerebrovascular diseases, improving the immunity, resisting fatigue, prolonging senility and so on.
