Coated vitamin c preparation for animal feed, production and use thereof

Abstract

A coated vitamin C preparation for animal feed comprises a particulate core containing vitamin C and a coating material composed of one or more fine powdery lipids having a melting point of at least 40.degree. C. and containing vitamin E. The coating material is present as an agglomerated coating layer surrounding the entire circumference of each particle of the particulate core. The coated vitamin C preparation is produced by a process, which comprises a step of bringing particles of a particulate core containing vitamin C into colliding contact with particles of a coating material composed of one or more fine powdery lipids having a melting point of at least 40.degree. C. and containing vitamin E, so as to form a coating layer of agglomerated particles of the coating material surrounding the entire circumference of each particle of the core. The coated vitamin C preparation is useful as a supplement to feeds for animals, such as, livestock, poultry and marine animals, by admixing same with the feed. The coated vitamin C preparation is superior, as compared with conventional coated preparations, in the coverage performance, vitamin C isolation effect against external influences of, such as, light, heat, moisture and atmosphere, and gives better preservation of the vitamin C activity, even upon admixing with feed mixtures, and enables the high absorbability of vitamin C by organisms.
