FIELD: fodder production. SUBSTANCE: waste of gauze in the capacity of cellulose-containing raw material is subjected to hydrolysis with hydrochloric-acid mother liquor of α-isoleucine followed by electrodialysis of hydrolizate at current density of 10-25 mA/cm2 to complete removal of chlorine ions and steaming down the material to a dry powdered state. Electrodialysis is conducted in installation with the following arrangement of membranes: cation-exchange membrane - concentration chamber - anion-exchange membrane - chamber with source solution (desalination chamber) - anion-exchange membrane - chamber with sodium hydroxide solution. EFFECT: higher efficiency. 2 cl
