The knowledge and application of collagen protein in humans can be considered to have a long history. Collagen protein from different tissues can be extracted and purified by corresponding appropriate processes, but there are also some collagen protein that are in the primary research stage and complete extraction and isolation protocols have not been found yet. So, what animals can collagen protein come from?
Source of collagen protein: Cattle
In a large number of beef production and consumption process, cattle bones and hides as the main byproducts, is widely used to extract collagen protein. Organic collagen protein is the main protein in cattle bones, containing more than 90%. It has a good ability to scavenge free radicals and inhibit the oxidation of polyunsaturated fatty acids cells.
Source of collagen protein: Pig
Study of the chemical composition of pig skin found that pig skin contains 70% water, 28% protein, ash 0.6% and chondroitin sulfate and other components. Pig skin protein collagen protein accounts for 87.7%, in addition to a small amount of keratin and elastin. Pig skin has a high homology with human skin tissue and the structure is relatively close. Therefore, the extraction of collagen protein from pig skin is beneficial to human absorption and use, and is often processed into beauty and moisturizing dressings.
Sources of collagen protein: Fish
Mainly from the flounder, sea eel, yellowfin tuna, Juncao fish, carp, tilapia, red drum fish, cod and other aquatic animals. The marine fish live in a high-pressure, high-salt environment, and this special living environment has created barrier tissues such as their skin and fish scales that have a natural advantage in promoting the healing of human skin wounds.
Fish skin is rich in collagen protein, with collagen protein content accounting for about 80% of the total protein content, much higher than other parts of the fish body. Marine-sourced collagen peptides like fish collagen protein peptide has the effect of relieving body fatigue, enhancing immunity, etc., with good development and utilization value.
Source of collagen protein: Frog
A study shows that the skin of the forest frog is rich in collagen protein. And other bioactive peptides in frog skin also gradually get people's attention, it can not only promote the body's absorption of amino acids, to meet the body's demand for nutrients but also for the treatment of hypertension, tumors and other diseases have a unique therapeutic effect.
Source of collagen protein: Donkey
The donkey skin from the donkey gum and gum because of its nourishing qi and blood, fetus, refreshing and educational effects in the market has been well-known. In fact, the main component of donkey and gum is collagen protein, organic collagen protein plays a major role.
The source of collagen protein: Deer
In addition to its high ornamental value, the deer also has a high medicinal value. The crude protein content in deer antler accounts for more than 50% of the dry weight mass, and collagen protein is the highest protein content in deer antler. In addition, from the deer bone, deer skin, deer placenta can be extracted from the collagen protein that can effectively enhance the body, strengthen the muscles and slow down the aging of the body.
Source of collagen protein: Chicken
Mammals are now the main source of collagen protein extraction, at the same time, people are beginning to pay more and more attention to the development of non-mammalian sources of collagen protein. Chicken feet, rich in protein (mainly collagen protein) and low fat content, is a good raw material for the preparation of collagen protein. In addition to chicken feet, chicken small intestine, chicken cartilage and egg membranes are also seen as promising candidates for collagen protein development.
