Preparation process of intestinal active polypeptide composition

The invention discloses a preparation process of an intestinal active polypeptide composition. The preparation method comprises the following steps: processing tuna raw materials through an antioxidant treatment procedure or an anti-gelling treatment procedure, separating moisture and fat in the tuna raw materials, retaining proteins in the raw materials, and performing enzymolysis on the proteins to obtain intestinal active polypeptides; meanwhile, the intestinal active polypeptide is mixed with astaxanthin and xanthophyll, and the intestinal active polypeptide composition is prepared. A special preparation process is adopted, the problem of raw material oxidation in the protein processing process is solved, and the peculiar smell of a finished product is reduced; and the gelatinization phenomenon of the protein in the enzymolysis process is solved, and the enzymolysis can be smoothly carried out. 本发明公开了一种肠道活性多肽组合物的制备工艺。本发明将金枪鱼原料经抗氧化处理工序或防胶凝处理工序加工，分离金枪鱼原料中的水分及脂肪，保留原料中的蛋白质，将蛋白质酶解得到肠道活性多肽；同时将肠道活性多肽与虾青素、叶黄素混合，制
