As the third generation of the latest biotechnology sugar biological engineering, biological sciences with a series of "most" give high evaluation: glycobiology is the new frontier of life science disciplines, the maximum life information is sugar chain and the smartest immune substance is an oligosaccharide, the most active, the most effective oligosaccharide material chitosan oligosaccharide is.

Chitosan is chitin derivatives (Ji Dingzhi) high-end materials, containing amino oligosaccharides. Its chemical structure and plant fiber is very similar, so it is called the edible cellulose animals, it is natural polysaccharide only with positive charged low molecular weight substances, and has a stable three-dimensional structure, special physiological activity, is highly functional food, is the perfect fourth generation health products (functional health products).

So in foreign countries, especially the developed countries, the chitosan oligosaccharide (chitin) and the use of development has been emphasized by the. Since 1811 French scholar branno first from crustacean shell isolated from chitin, the United States, Europe, the medical profession, universities, nutrition and food research institutions have been put into the study. Japan will be the first of chitin, chitosan and chitosan oligosaccharide by clinical practice to the identity of the functional food market, and become the Japanese Ministry of health and welfare (equivalent to China's Ministry of Health) only permitted to propaganda effect of functional food, also the Japanese government also invested a huge sum of money to be development and market promotion. Its sales have accounted for Japan's first health food. The result is: in just 30 years to the average life expectancy in Japan ranked first in the world!
