Collagen Chemical Properties
 
Application

1. Application in the medical and health industry Collagen is mainly used as a scaffold material, skin and bone in tissue engineering. With the application of collagen in tissue engineering, bioengineered membranes are also used more widely, such as vascular membranes, heart valves and ligaments. Collagen has good biocompatibility and biodegradability, can be degraded and absorbed, and has good adhesion. Therefore, it has a unique skin repair function, which can be used to make skin graft materials after modification. Collagen can form the skeleton of the extracellular matrix, is an important component of the cell, anchors and supports the cells, and provides a proper microenvironment for cell proliferation and growth, and provides a good nutritional supply. Therefore, whether the collagen is absorbed into the host as a skeleton of the new tissue or absorbed into the host before being absorbed, it becomes a part of the host tissue, and has a good coordination effect with the matrix surrounding the cell, which is beneficial to the proliferative repair of the epithelial cells, thereby promoting the wound. Healing, which can be used for burns, wound repair, treatment and care, can reduce and alleviate the degree of burns and burns. Collagen biological dressing has two advantages: First, the preparation method is simple, convenient and easy to process; Secondly, it has good adhesion, suitable for granulation tissue and epithelial cell formation, can reduce wound contracture and antigen reaction, and hemostasis Good, easy to absorb tissue exudates and other characteristics. Collagen can also be used in the treatment of ophthalmic diseases because of its unique characteristics. Collagen can promote the repair and cell growth of corneal epithelial cell damage, and can be dissolved in tears, and has the ability to guide epithelial cells into the defect area. At the same time, its degradation products can be utilized by new cells to synthesize new collagen and act as a connecting cell. Therefore, it is widely used in the treatment of ophthalmic diseases. Collagen can also be used as a carrier for eye administration, and has the effects of increasing drug concentration, prolonging the action time of the drug, and reducing the systemic drug toxicity of the drug, and has broad development prospects. Collagen is also widely used in clinical medicine for cosmetic orthopedics, treatment of periodontal diseases, hard tissue repair, nerve repair and regeneration, periodontal nerve repair wrapping materials, artificial organs, pacemakers, and human internal organs. Add things and so on.

2. Application in cosmetics Collagen can be extracted from animal skin. In addition to collagen, animal skin contains proteoglycans, chondroitin sulfate and other proteoglycans, which are natural moisturizing factors and are important for maintaining skin moisture. Substance, and has the effect of preventing the conversion of tyrosine in the skin to melanin. Collagen is similar to the collagen structure in the skin and the stratum corneum of the skin. It promotes the proliferation and repair of epithelial cells, supplements nutrients such as amino acids, improves the environment in which skin cells survive, promotes the metabolism of skin tissues and enhances circulation, causing damage and aging. The skin is filled and repaired, and has good compatibility, affinity and permeability with the skin, and can be fully absorbed by the skin, so that the skin is full, wrinkles are stretched, and the skin density and tension are increased. Therefore, collagen has pure natural moisturizing, whitening, freckle, anti-wrinkle and other effects, and can be widely used in the cosmetics industry. Today, many cosmetics such as facial masks, eye creams, skin creams and the like are contained in the market.

3. Application in the food industry Collagen has two applications in food: one is function, and the other is nutrition. Collagen peptides can be directly consumed as functional foods, such as chewable tablets, protein powders for athletes, and enteral nutrition preparations. People who eat foods rich in collagen can effectively delay the aging of the body, strengthen the bones and strengthen the body, and also play a health-care effect such as weight-reducing blood pressure and calcium supplementation. When collagen is treated with a specific enzyme, it can destroy the hydrogen bonds in its molecule and destroy its original tight supercoiled structure. The loosely formed small molecular substance can be added to the meat to improve connective tissue and increase protein. The content is good and nutritious. The enzymatic hydrolysate of collagen can also be used as a modifier for frozen foods, as a tackifier, with a low melting point, easy to dissolve, and has the characteristics of being imported. Therefore, collagen is widely used in foods such as jelly, cheese, ham, canned food, and bread. Further, by utilizing the film forming property of collagen, it can be used as a film material for curing enzymes and a meat food label. Collagen can also be used as a food adhesive synthetic fiber film and as a food protective layer. It is used as a wrapper for meat, fish, etc. As a food protective layer, it has antioxidant properties and keeps the color of the meat food bright.

4. Applications in other fields With the continuous research on collagen, the application of collagen in other fields is increasing and has a good development prospect. For example, if the remaining waste in the tanning process is rich in collagen, it can be used as an animal protein resource for feed to realize resource utilization. After denaturation of collagen, it can be used in the textile industry to improve its textile properties. At the same time, collagen has been used more and more in light industry such as paper industry, leather industry and daily chemical industry. With the continuous development and advancement of research technology, the research on collagen will continue to deepen, and collagen will be applied more widely.
