process for the preparation of mixtures for use in food and feed comprising active substances distributed in a uniform way.

摘要

Mixtures for human or animal feed use comprising active substances are prepared by applying the active substance to a granular support of mineral or vegetable type and fixing the active substance to the support by coating the granules supporting the active substance with a polymer substance which disgregates in an aqueous environment. The active substance applied in this manner does not come into contact with other components of the mixture. The product thus obtained is mixed with flour or meal for human or animal feed use to obtain the final mixture. The active substance is uniformly distributed in the final mixture.
