Scientists have discovered that chitin, the sixth element of human life, is the sixth life element besides protein, fat, sugar, vitamins and minerals, which was discovered by French scientist Brakno. It is widely found in the cell walls of crustaceans such as shrimp, crab, insects and algae. Experts say that chitin has a special chemical structure, which has six functions: regulating immunity, activating cells, inhibiting aging, preventing diseases, promoting healing and regulating human physiological functions. In recent years, tumors, diabetes, physiological dysfunction and cardiovascular and cerebrovascular diseases have increased year by year. Medical experts say that the main reasons for this phenomenon are environmental pollution and the destruction of biological chain, which makes it impossible for people to obtain chitin from food.

Chitin is the only animal dietary fiber and a rare alkaline polysaccharide with positive charge in nature. It not only has various characteristics and functions of dietary fiber (such as participating in metabolism without producing energy, being beneficial to the reproduction of normal intestinal flora, defecation and regulating energy metabolism, and being used in the diet of diabetic patients), but also has important physiological and pharmacological significance. In recent ten years, Chinese and foreign scientists have taken it as the sixth life factor for research and development. The life value of chitin was discovered by a large number of conquerors, and the news media rushed to report it. A large number of medical and health institutions, colleges and universities have repeated experiments and papers, and the conclusions are surprisingly similar. However, the molecular weight of chitin is too large to be easily absorbed by human body, while chitooligosaccharides degraded by biochemical technology (smaller and purer than chitosan) are easily absorbed and utilized by people, which is a good healthy food, but it may be more expensive!
