More Information
Summary:The invention discloses a preparation method and application of cowhide gelatin, and relates to the technical field of gelatin preparation, the preparation method sequentially comprises the steps of neutralizing and washing, enzymolysis, extraction, filtration, concentration and freeze forming, the extraction comprises the steps that a dilute gelatin solution is obtained after extraction is conducted through a three-time gelatin extraction process, the extraction temperature is 50-90 DEG C, and the pH value is controlled to be 4.5-6.5; compared with traditional one-time high-temperature submission, the submission mode of multiple gradient heating has the following advantages that extraction is conducted for 4-6 hours at the temperature of 50-70 DEG C for the first time, the three-dimensional structure of gelatin is protected to the maximum extent through submission, and the obtained gelatin has high congelation strength; extracting for 4-6 hours at the temperature of 70-80 DEG C for the second time, so that t
