2. Collagen is a macromolecule, and hydrolyzed collagen is a kind of collagen that can be hydrolyzed into small molecular collagen peptides. Probiotic collagen short peptide capsules can keep intact short peptide molecules without hydrolysis, and the capsule protection is more stable, which can be directly absorbed by the intestine.
3. Collagen peptides with relatively small molecular weight are mainly formed after hydrolysis of collagen molecules. Because of the unique triple helix structure of collagen, its properties are very stable, which can not be decomposed at general processing temperature and short-time heating, and it is difficult to be digested, absorbed and fully utilized by human body.
Hydrolysis can greatly improve its absorption and utilization rate, and promote the absorption of other protein in food.
4. Collagen polypeptide contains not only the uncondensed terminal carboxyl and amino groups at both ends of the peptide chain, but also ε-NH2 of side chain Lys and -COOH of Asp and Glu. Collagen polypeptide can be completely dissolved in water (cold water can also be dissolved), and the aqueous solution has low viscosity, fluidity at a high concentration of 60%, good acid and alkali resistance and no precipitation in the presence of acid and alkali;
Good high temperature resistance, no precipitation when heated at 200℃, good oil absorption, foaming and water absorption.

Hydrolyzed collagen is a natural biological product, which is rich in bioactive substances such as various peptides necessary for human metabolism, especially hydroxyproline (>: 12%), which is the main material basis of connective tissue.
Second, a brief introduction to collagen:
Collagen is a biopolymer, the main component of animal connective tissue, and the most abundant and widely distributed functional protein in mammals, accounting for 25% ~ 30% of the total in protein, and even more than 80% in some organisms.
Animal tissues from livestock and poultry are the main way for people to obtain natural collagen and collagen peptides. However, due to related animal diseases and certain religious beliefs, people have restricted the use of collagen and its products from terrestrial mammals, and now they are gradually turning to marine life for development.
The European Food Safety Agency (EFSA) has confirmed that even collagen from animal bones is unlikely to be infected with mad cow disease and other related diseases.
Due to the differences in amino acid composition and crosslinking degree, aquatic animals, especially their processing wastes, such as skin, bone and scales, contain rich collagen, which has many advantages that livestock collagen does not have. In addition, collagen from marine animals is obviously superior to collagen from land animals in some aspects, such as low antigenicity and hypoallergenicity.
Therefore, aquatic collagen may gradually replace terrestrial collagen.
