collagen, accounting for about 20% of the total protein of mammals, is also a very important protein in the human body. It is mainly found in connective tissues, and is not found in plant tissues. It has a strong stretching ability, is a major component of ligaments, collagen is also a major component of the extracellular matrix. It keeps the skin elastic, and the aging of collagen causes the skin to wrinkle. Collagen is also the main component of the cornea of the eye, but it is composed in crystalline form. Like other proteins, collagen cannot be absorbed directly by the body and is broken down into amino acids when taken orally.

Application:

1 Fresh cow skin is used as raw material, after high temperature degreasing treatment, the protein is separated by enzyme combined with advanced high-frequency assisted extraction technology, and the products with high peptide content are prepared by directed enzyme digestion, decolorization, flavor removal, concentration and drying. Most of the products retain the activity of collagen polypeptide, and have the characteristics of high activity, good absorption, good stability, high solubility and high purity.

2 It is mainly extracted from tilapia, cod fresh skin and fish scale by enzymatic directed shearing technology. Mainly Type I collagen, the product is rich in 19 kinds of amino acids, and the molecular weight is between 2000-5000D length.
