摘要: Described is a method for the preparation of a gelatin hydrolysate having a decreased endotoxin content, comprising the steps of incubating a solution of gelatin of gelatin hydrolysate at a temperature of 70-125° C. at a pH of 3.5 or less for a time period of at least 15 minutes, and recovering the gelatin hydrolysate. Further a gelatin hydrolysate thus obtained is described.

摘要: The present disclosure is directed to processes for reducing the endotoxin level in gelatin and the resulting gelatin with low endotoxin content. The process includes dissolving a salt in a gelatin solution and filtering the gelatin-salt solution using anion exchange to reduce the endotoxin level. After reducing the endotoxin level of the gelatin-salt solution, the low endotoxin gelatin-salt solution is desalted to remove the salt, thereby producing a low endotoxin gelatin solution.

摘要: A method of preparing a sturgeon skin gelatin with antioxidant activity includes: 1) soaking sturgeon skin in water, and sonicating the sturgeon skin; 2) cutting the sturgeon skin, soaking the sturgeon skin in a NaOH solution, and soaking the sturgeon skin in an HCl solution; 3) washing the sturgeon skin of step 2) to neutral, placing the sturgeon skin in an extraction solution for extracting sturgeon skin protein; and 4) obtaining the sturgeon skin gelatin. A method of preparing a sturgeon skin gelatin film includes: 1) dissolving sturgeon skin gelatin in water to obtain a sturgeon skin gelatin solution; 2) adding glycerine to the sturgeon skin gelatin solution; and 3) obtaining the sturgeon skin gelatin film.
