COATED VITAMIN C PREPARATION FOR FEED, PRODUCTION THEREOF AND USE THEREOF

摘要

PURPOSE:To obtain the subject coated preparation excellent in covering properties, shielding light, outer air, etc., and capable of maintaining a high activity by bringing a specified coating material into contact with a vitamin C-containing powdery core material, making the coating material to collide with the core material and forming a powdery coating material layer on the whole surrounding surface of the core material. CONSTITUTION:With (A) a core material containing >=10wt.% vitamin C and having 0.1-1000mum particle size, (B) a coating material composed of a powdery lipid containing 0.1-10wt.% vitamin E and having >=40 deg.C melting point and 0.1-100mum particle size is brought into contact and the coating material is made to collide with the core material. An objective coated preparation having 0.1-50 weight ratio of the component (A) to the component (B) is obtained thereby.
