The invention discloses a method for evaluating the digestion characteristics of bovine bone collagen polypeptide, which comprises the following steps: (a) preparing digestive juice, including preparing simulated saliva SSF, simulated gastric fluid SGF and simulated intestinal fluid SIF, and performing simulated in-vitro digestion process by using a GI20 in-vitro simulated digestion system, including i oral cavity, ii stomach and iii small intestine; (b) determining the digestion characteristics of collagen polypeptides of different molecular weights comprising determining the digestibility of the digest in step (a) before and after digestion in the mouth i, stomach ii and small intestine iii. The digestion characteristic evaluation method of the bovine bone collagen polypeptide provided by the invention is used for measuring the digestion characteristics of the collagen polypeptides with different molecular weights under different enzymolysis conditions, and rapidly acquiring data by adopting a complete simulation mode, thereby providing an effective means for large-scale production of the collagen polypeptides with different molecular weights for enterprises. |
