Its appearance is light beige to white, nature dissolved in concentrated hydrochloric acid, phosphoric acid, sulfuric acid, alkali and other insoluble in organic solvents chitin shelf life, not soluble in water. Chitin is the only positive dietary fiber positively charged. It is widely used in industrial, medical, cosmetic and other fields. Chitin exists in nature in the lower plants fungi, algae cells, crustaceans shrimp, crab shell chitin insects, higher plant cell walls, etc., in an amount not less than the rich in cellulose, cellulose is in addition Another important category of polysaccharides outside. It is estimated that in nature Weifang chitin, chitin biosynthesis annual amount of up to 100 billion tons. Chitin is the application from crab, shrimp in genetic engineering of animals to extract cellulose polymer chitin specifications, is the reputation of the scientific community as "sixth element of life" and therefore the government has been identified in Europe and America for functional immune substances. In the fungus, Cordyceps and other plants also contain trace "chitosan", but the content is only between 2% -7%. Chitin is positive dietary fiber in the universe only positively charged.
