How Is ZGL Collagen Obtained?

Collagen can be extracted from foods rich in collagen. There are many collagen-containing foods in our daily lives, such as white fungus, tendons and pig's trotters. Collagen is usually extracted through collagen hydrolysis and enzymatic hydrolysis, and the resulting collagen powder is white. When you brew collagen powder in water using a glass, you will find the solution is very clear.

Collagen is a biopolymer and the main component of animal tissue. In mammals it is also an abundant and widely distributed functional protein, accounting for 25%-30% of total protein and even up to 80% in some organisms, varying among aquatic animals due to differences in amino acid composition and degree of cross-linking.

In particular, the abundant collagen contained in processing by-products —— skin, bone and scales — has many advantages that livestock collagen lacks. Moreover, the collagen of marine animals is clearly superior to that of land animals in terms of low antigenicity and low allergenicity. As a result, collagen from aquatic products may gradually replace that of land animals.

After collagen is absorbed by the skin, the skin's ability to retain moisture is enhanced, maintaining the skin's water-oil balance and helping to prevent excessive oil secretion, long-term clogging and enlarged pores. With good biocompatibility, biodegradability and bioactivity, collagen is widely used in food, medicine, tissue engineering, cosmetics and other fields.
