METHOD OF PROTECTING ACTIVE INGREDIENT FROM DEGRADATION DURING PELLETING

摘要

Systems for protection against degradation during pelletization of one or more physiological or pharmacologically active substances include, in particular, microparticle or granular compositions for use in the livestock sector and / or the veterinary sector. The microparticles comprise a core comprising one or more substances having pharmacological action, a food supplement or diagnostic medium, said one or more substances being characterized by the presence of a basic functional group comprising an amine functional group in a chemical structure . The core also comprises one or more carboxylic acids and / or salts thereof, and ultimately one or more excipients. The core is coated by an outer layer of fat or wax, and preferably by a mixture of glycerides of fatty acids.
