METHOD FOR OBTAINING HIGHLY DIGESTIBLE CHELATE COLLOID FORM OF ESSENTIAL MICROELEMENT OF ZINC

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to a method for obtaining highly digestible chelate colloid form of essential zinc microelement. Method is two-step synthesis. First stage involves preparation of solution of 0.3 n. sodium hydroxide, in which riboflavin and lysine hydrochloride are dissolved, then to obtained reaction mixture is added zinc sulphate zinc and formed pulp consisting of residues of zinc riboflavinate and lysinate and their solutions, mechanically mixed on a magnetic mixer with continuous barbotage with nitrogen for 10 hours at a boiling point of a water bath, the finished product is filtered, washed with cold water and dried in air in a darkened place. At the second step, zinc lysinate-riboflavinate is dispersed in water to obtain a colloidal solution under ultrasonic radiation exposure conditions with following values of parameters: working solution sounding frequency of 20–48 kHz; ultrasonic modulation frequency 5–100 Hz; working solution sounding time of 5–60 minutes; relative power of US-radiation 50–100 W/l.;EFFECT: high biological activity and safety of the zinc microelement.;1 cl, 10 dwg, 3 ex
