The impact of animal species on the adhesion of industrial gelatin, collagen peptides of different animals such as cattle, sheep, pigs and dogs are also different. Therefore, the quality of the products of gelatin manufacturers near the cattle and sheep slaughterhouses and pig scraps as raw materials for gelatin will definitely There are differences.

The crystallization water of collagen is similar to the crystallization water of metal salts. The different crystallization water content is different, which causes the actual net content of gelatin to be reduced, which is also the reason for the difference in the adhesion of industrial gelatin. The raw material composition affects the cohesiveness. The raw materials of industrial gelatin are mainly animal skin, bones, tendons. The collagen peptide chain and amino acid of each raw material are slightly different. The collagen peptide chain of tendons is the most stable, so the tendons The produced industrial gelatin has strong adhesion, and the skin produced industrial gelatin has poor adhesion. However, general industrial gelatin manufacturers order raw materials uniformly at the slaughterhouse, and the proportions of tendons, skin, and skin are all matched according to the overall proportion of animals, so this has little effect.
