FIELD: medicine, pharmaceutics.
SUBSTANCE: invention refers to medicine, more specifically to producing chitosan oligomers possessing biological activity and applicable in food industry and medicine. In a method for producing chitosan oligomers, a chitosan solution is taken in the concentration of 0.025-0.075% (weight/volume) and exposed to low-frequency ultrasound of the intensity of 92-460 Wt/cm2 for 5-30 minutes.
EFFECT: reduction in price of the chitosan oligomers production combined with promotion of higher medium viscosity molecular weight of the product within the range 25 ÷ 120 kDa.
