How to stabilize chitosan partial decomposition products, how to store chitosan partial decomposition products and preservatives for foods

摘要

PROBLEM TO BE SOLVED: To stabilize and store a chitosan partial decomposition product which can be stably stored without reducing the bacteriostatic activity of the chitosan partial decomposition product even if the chitosan partial decomposition product is stored at room temperature or high temperature, and to be stable. To provide a preservative for foods containing a partially decomposed product of chitosan as an active ingredient. SOLUTION: A method for stabilizing a chitosan partial decomposition product and a method for preserving the chitosan partial decomposition product, including coexistence of the chitosan partial decomposition product with cyclodextrin and / or trehalose, and a method for preserving the chitosan partial decomposition product, and the chitosan partial decomposition product, cyclodextrin and / or It is a preservative for foods containing trehalose and a stabilized partially decomposed chitosan as an active ingredient.
