Collagen can be extracted from foods rich in collagen. There are many foods that contain collagen in our life, such as silver fungus, tendons, pig’s feet, etc. Collagen extraction is usually performed through collagen hydrolysis and enzymatic hydrolysis, producing collagen powder that is white. When you brew collagen powder with water, you will find the solution very clear if you use a glass.

Collagen is a biopolymer that is a major component of animal tissue. It is also an abundant and widely distributed functional protein in mammals, accounting for 25%-30% of total proteins and even up to 80% in some organisms. Due to differences in amino acid composition and cross-linking, aquatic animals,

especially the rich collagen contained in its processing waste - skin, bones and scales - has many advantages not found in collagen from livestock. In addition, collagen from marine animals is significantly better than that from terrestrial animals in terms of low antigenicity and hypoallergenicity. As a result, collagen from aquatic products may gradually replace collagen from terrestrial animals.

After collagen is absorbed by the skin, the skin’s ability to lock in water is enhanced, and the skin’s water-oil balance is always maintained to avoid high oil secretion, long-term blockage and enlarged pores. With good biocompatibility, biodegradability and bioactivity, collagen has been widely used in food, medicine, tissue engineering, cosmetics and other fields.
