ABSTRACT:
A process for the preparation of an enzyme-containing granulate is disclosed where an aqueous enzyme-containing liquid is mixed with a solid carrier and optionally additive ingredients and is mechanically processed into granules, dried and subsequently coated with polyethylene glycol. The solid carrier preferably essentially consists of an edible carbohydrate polymer. Additive ingredients that could be further incorporated in the formulation of the granules are a gel-forming or slow dissolving compound such as polyvinyl alcohol, water soluble inorganic salts comprising divalent cations and trehalose. This enzyme granulate is suitable for the manufacture of animal feed compositions by mixing feed ingredients with the granulate, treating with steam and pelleting. The compositions show improved enzyme stability during the pelleting process 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.
