Composite oligopeptide nourishment and preparation method thereof

The invention relates to a composite oligopeptide nutriment and a preparation method thereof, the composite oligopeptide nutriment comprises the following raw material components in percentage by mass: 74.5-85% of vegetable protein, 13.5-25% of animal protein and 0.5-1.5% of compound protease, and the sum of the content percentages of all the components is 100%. The composite oligopeptide nutrient solution is obtained through liquid mixing, enzymolysis, filtration separation, molecular sieve separation, mixing and concentration, or the composite oligopeptide nutrition powder is obtained through further drying. The obtained composite oligopeptide product has uniform molecular weight, and oligopeptide sources comprise plant sources and animal sources. The oligopeptide nutrient provided by the invention has the characteristics of uniform peptide molecular weight, rich amino acids, no bitter taste and the like. 一种复合短肽营养品及其制备方法，其原料组分及质量百分数为：植物蛋白74.5-85％，动物蛋白13.5-25％，复合蛋白酶0.5-1.5％，各组分含量百分数之和为100％。经过调液、酶解、过滤分离、分子筛分离
