What is fish collagen powder, and what are the ways to distinguish it?
1. Solubility: Collagen is insoluble in water. Only the powdered fish collagen powder extract will dissolve slowly in warm water after the molecular weight structure is reduced by low-temperature enzymatic degradation technology. Stirring makes it dissolve more uniformly. It is beneficial to gastrointestinal absorption, and the better the extraction process, the easier it is to dissolve.
2. Taste: The pure fish collagen powder extract has a light fishy smell, similar to the taste of fishy fish and soy flour, except for those with added flavoring agents.
3. Color: The fish collagen powder extract will appear transparent and pale yellow when dissolved in water, because a few molecules of collagen powder react with hydrogen molecules in the water and become a kind of chlorine-based acid.

4. Source: In terms of safety, the safety of fish extraction is the highest;
5. Molecular weight: namely: polypeptide or oligopeptide. In terms of absorption rate, oligopeptide has obvious advantages over polypeptide.
6. State: The purity of powder is the highest, and oral liquid, tablet, capsule, etc. will be added.
7. Color: The fish collagen powder is white instead of milky white; the solution is colorless or light yellow.
8. Odor: slightly fishy smell, not fishy smell.
