Collagen is a biopolymer, the main component in animal connective tissue, and it is also the most abundant and widely distributed functional protein in mammals, accounting for 25%-30% of the total protein, and some organisms can even reach more than 80%. .

There are many types of collagen, the common types are type I, type II, type III, type V and type XI.

Collagen is widely used in food, medicine, tissue engineering, cosmetics and other fields because of its good biocompatibility, biodegradability and biological activity.

Among Chiti’s hot-selling products, collagen peptides are the most important component. The selection of materials mainly comes from "deep sea cod" and "lake whitefish".

High quality from marine life

In the early days, animal tissues derived from livestock and poultry were the main way for people to obtain natural collagen and collagen peptides. However, related animal diseases and certain religious beliefs restricted the use of terrestrial mammalian collagen and its products.

With the development of science and technology, it is now gradually turning to the development of marine organisms. The European Food Safety Agency (EFSA) has confirmed that even collagen derived from animal bones is not likely to be infected with mad cow disease and other related diseases. To

Due to differences in amino acid composition and degree of cross-linking, the abundant collagen contained in aquatic animals, especially their processing wastes-skin, bones, and scales, has many advantages that livestock collagen does not have.

In addition, collagen derived from marine animals is significantly better than collagen derived from terrestrial animals in some aspects, such as low antigenicity and hypoallergenic properties. Therefore, aquatic collagen may gradually replace terrestrial animal collagen.

Hot-selling lake whitefish in the American market

Lake whitefish is a species of whitefish unique to North America. It is widely distributed in lakes, reservoirs and rivers in the 40-70°N latitude area of North America. Mainly distributed in Canada and the United States.

Through scientific determination, the muscle nutrition of the lake whitefish (Coregonus cluncaformis) shows that the meat content of the lake whitefish is 60.82%, the crude protein content in the muscle (fresh sample) is 16.85%, the crude fat content is 4.39%, and the moisture content is 77.06%. , The ash content is 1.13%. The fish muscle contains 17 amino acids, the total amount is 62.00% (mass fraction, dry sample), of which 7 are essential amino acids (excluding tryptophan), the total amount is 28.16%, accounting for 45.42% of the total amount of amino acids; the composition ratio of its essential amino acids basically meets the FAO/WHO standards. The restrictive amino acids of lake whitefish are (methionine + cystine), threonine and (phenylalanine + tyrosine) ), the essential amino acid index is 59.80, and the total amount of 4 kinds of umami amino acids is 19.94%.

The abundant protein content and the essential amino acid reserves of the human body make the lake whitefish a good collagen raw material.

Uncontaminated arctic cod

Cod is a relatively common type of production and daily diet. Many people know its deliciousness but do not know that it has a high health value. In addition to fishing in the Atlantic Ocean, the quality of cod from the Arctic Ocean in Russia is the best, because the waters are less polluted and not small, ensuring the quality of collagen extraction.

Value the quality

Chiti always pursues product quality and walks in the forefront.

Imported lake whitefish from America uses enzymatic hydrolysis to extract high-quality collagen, scientific testing and experiments, precise formula, non-denatured.

Strictly selected Arctic deep-sea cod, high nutritional level, specific antifreeze protein, the marine environment is protected by international nature, no antibiotics, no heavy metal pollution, no animal diseases, it is an excellent choice for collagen material.

Chiti's scientific research team has visited North America and Russia many times, strictly selecting suppliers of collagen raw materials and establishing long-term cooperative relationships. The collagen produced has undergone multi-stage testing before being introduced to the market, and the quality of the products is guaranteed from the raw materials. All efforts and efforts stem from the team's respect and awe for the cause of human health, but also from the commitment and love to customers.
