What Are Collagen Peptides Extracted

Collagen peptide is a kind of collagen-rich fresh animal tissue (including skin, bone, tendon, tendon, scale, etc.) as raw materials, through extraction, hydrolysis, refining and production, the relative molecular weight is less than 10000Da products. Collagen peptides contain a variety of nutrients and collagen, after drinking, you can replenish enough collagen peptides for the skin, and at the same time can increase skin elasticity, which can play a very good role in delaying skin aging, improve fine lines and sagging symptoms on the skin, and make the skin look more youthful and beautiful.

 

The sources of collagen peptide raw materials are as follows:

1. The skin, bones, tendons, tendons and scales of fresh cattle, pigs, sheep and fish and other animals that have passed the quarantine provided by slaughterhouses, meat factories, canning factories, vegetable markets, etc.

2. Before the tanning process, the sheared skin with raw edges or the inner layer of skin under the cut.

3. Clean bones and naturally dried aggregates processed by bone processing plants.

4. Edible aquatic animals swim bladder, edible echinoderms, jellyfish, etc.

 

The main sources of collagen extraction available in the market are divided into two categories: bovine/porcine collagen and fish collagen. Fish collagen is divided into freshwater fish skin collagen, freshwater fish bone collagen, deep-sea fish skin collagen, and deep-sea fish scale/fish bone collagen according to the raw material part and growing water.

 

Bovine and pig collagen: It is extracted from the bones and skins of pigs, cattle and other animals. Its production is high and its price is low. However, the fat content of pig original protein is high, and it is easy to gain weight after long-term use, and the same cattle and pig breeding environment is uncontrollable, and the feed is easy to contain hormones, and there is a risk of viruses such as mad cow disease and foot-and-mouth disease, so the safety of raw materials is relatively low.

 

Fish collagen: It is extracted from fish bones, fish scales or fish skin, among which fish skin collagen is the best for the skin, it belongs to type I collagen, the amino acid composition is closest to human collagen, with a high concentration of glycine, hydroxyproline and proline. When ingested in fish skin collagen, hydroxyproline is not completely digested and decomposed by free high amino acids, but directly enters the bloodstream, stimulates cell activation, and promotes collagen synthesis. At the same time, the molecular weight is much smaller than that of bovine and pig collagen, which can be directly absorbed into the bloodstream by the small intestinal wall, so the bioavailability (absorption rate) is higher, about 15 times that of other collagen.

 

In addition, the marine ecological pollution is serious, so the freshwater fish in the ecological lake reservoir are safer than the deep-sea fish, and the ecological restoration project of the lake and reservoir makes the fish growth environment cleaner, without water pollution, and there will be no hormonal influence. Due to its high requirements for ecological restoration technology and more complex extraction process, fish skin collagen has a slightly higher cost and selling price, which is suitable for beauty lovers with higher health requirements.
