【Abstract】 The chitin can be obtained with the technique of proteinase ferment decomposition, decalcifying with the organic acid, and decolorizing with the ethyl alcohol from the crab shell. The new process can also synthetically use enzymolysis, acidolysis barren liquor. We can obtain top grade amino acid condiment with strong seafood flavor in which contain 8% amino acid, and obtain calcium citrate crystalloid which is used extensively in foodstuff industry. The barren liquor can be used circularly.更多还原
