The present invention describes a process for the preparation of an enzyme- containing granulate wherein an aqueous enzyme-containing liquid is, optionally supplemented with a solid carrier and/or additive ingredients, processed into granules, dried and subsequently coated with a polyolefin, preferably polypropylene and/or polyethylene. This coated enzyme granulate is suitable for the manufacture of animal feed compositions by mixing the granulate with feed ingredients, treating with steam and pelleting. The coated granulates show high enzyme stability during pelleting conditions and during storage. At the same time, the dissolution time of the granule is very short so that the bioavailability of the enzyme to the animal is improved.

L'invention concerne un procédé de préparation d'un granulé renfermant des enzymes consistant à traiter un liquide aqueux renfermant des enzymes, éventuellement administré conjointement avec un excipient solide et/ou des ingrédients additifs, en granulés, à les sécher et à les enrober ensuite d'une polyoléfine, de préférence, du polypropylène et/ou du polyéthylène. Ce granulé d'enzymes enrobé est conçu pour la fabrication de compositions alimentaires animales, par mélange du granulé avec des ingrédients alimentaires, par traitement à la vapeur et par boulettage. Les granulés enrobés présentent une stabilité élevée des enzymes à l'état de boulettage et pendant le stockage. Le temps de dissolution du granulé est très court, de manière à améliorer la biodisponibilité de l'enzyme pour l'animal.
