| titleOfInvention | Process for the preparation of powdered chitosan oligomers |
| abstract | A process for preparing powdered chitosan oligomers, comprising The formation of a chitosan solution in an acid; The introduction of ferments into the resulting chitosan solution, which ensures fermentative hydrolysis of the chitosan to produce a reaction mixture; - Carrying out a fermentative hydrolysis of the reaction mixture, which ensures the preservation of the chitosan oligomers and a complex salt formed by organic acid and chitosan oligomers; The filtration of the reaction mixture to isolate the resulting hydrolysis products therefrom; - the drying of the isolated products; characterized in that the formation of the chitosan solution takes place with a chitosan concentration of 3-4% in the aqueous solution of an organic acid at a pH of 3.5 to 4.4, the hydrolysis with an enzyme complex comprising chitosanase used in combination with papain at a ratio of 1: 1-1,2 until a dynamic viscosity of the reaction mixture of 1.50 to 1.58 mPa ยท s (1 , 50 to 1.58 cP), ... |
