Chitosan, chitosan oligosaccharide commercial products has spread all over the various fields, mainly related to the functional food and medical supplies (artificial skin, artificial ligament, artificial blood vessel, surgical sutures), the main function of chitosan in human health is reflected by the chitosan oligosaccharide and polysaccharide chitosan oligosaccharide metabolic end product of glucosamine and N-acetylglucosamine is substances necessary for human cells. In the absence of the substance, the body's own immune function will decline, leading to hypertension, cardiovascular disease, cancer, and other modern difficult disease. People within the mother's body has a self synthesis of the two substances of instinct, adult after the function disappeared, the must be from the food intake.
In the 1970s, scientists in the nutrition of cells, structure and function studies in the process found that due to the industrialized production, pesticide and fertilizer, greenhouse technology, no soil cultivation technology etc. a lot of use and chitin material disappeared in the human food chain, human from food not in time to make up, must be artificially added.
The chitosan oligosaccharide will synthesis of these two substances in the human body (part of the effect of lysozyme in vivo). Therefore, the medical profession will oligochitosan called after the fat, protein, sugar, minerals, vitamins maintain physical alkaline elements, so called the sixth life element. Scientists pointed out, people should be like the uptake of top five substances, the moderate daily intake of oligochitosan. So the application of chitosan in the aspects of the most remarkable.
