FIELD: natural compounds, chemical technology and biotechnology.
SUBSTANCE: invention describes a method for preparing chitosan oligosaccharides. Method involves enzymatic depolymerization of chitosan with chitosanase in an aqueous solution in the presence of acetic, ascorbic, succinic acid or their mixtures followed by filtration and drying. After drying prepared chitosan oligosaccharides are subjected for low-temperature treatment with liquid nitrogen. Method provides preparing chitosan oligosaccharides without unfavorable after tasting.
EFFECT: improved preparing method.
