Abstract: PURPOSE: A method for preparing a water-soluble free amine chitosan is provided, to obtain a pure water-soluble free amine chitosan with a molecular weight of 1,000-100,000 Dalton. CONSTITUTION: The method comprises the steps of treating a solution of salts of an organic acid or an inorganic acid of chitosan oligosaccharide with a trialkylamine; adding an organic solvent to the solution to recover the chitosan oligosaccharide by removing an organic acid or an inorganic acid in the form of a trialkylamine salt; and treating the chitosan oligosaccharide solution with an inorganic acid and purifying the solution with an activated carbon/ion exchange resin column. Preferably the organic acid is selected from the group consisting of lactic acid, acetic acid, propionic acid, formic acid, ascorbic acid and tartaric acid; and the inorganic acid is selected from the group consisting of HCl, HNO3 and H2SO4.

Abstract: PURPOSE: A method for preparing a soy sauce or soybean paste using chitooligosaccharides is provided to use a chitooligosaccharide solution with molecular weight of 13,000 or less as water. CONSTITUTION: A method for preparing a soy sauce or soybean paste using chitooligosaccharides comprises a step of using a chitooligosaccharide solution as water in a producing process of soy sauces or soybean paste. The average molecular weight of the chitooligosaccharide is 13,000 or less. A method for preparing the chitooligosaccharide solution comprises the following steps of: dissolving chitosan in hydrochloric acid to obtain a chitosan-hydrochloride solution; adding a chitosanase to the chitosan-hydrochloride solution to form a chitosanoligosaccharide; filtering the chitosanoligosaccharide-containing solution to remove unreacted materials and refining with a ultrafiltration membrane; and adding caustic soda to the refined solution to neutralize it and desalting and concentrating the neutralized solution.
