Benefits of technology

[0008]One object of the present invention is to provide an enzyme granule with good pelleting stability.
[0009]A second object of the present invention is to provide a simple process for obtaining enzyme granules with good pelleting stability.
[0010]It has surprisingly been found that zinc salts of organic acids have a very positive effect on enzyme stability during pelleting, and per se stability if formulated together with the enzyme.

Problems solved by technology

Active compounds present in the feed such as enzymes are not very stable at high temperatures and humidities, and thus, a large surplus of enzymes has to be used, or enzyme free feed components are pelletized and steam treated, where after an enzyme containing slurry or solution is coated onto the steam treated pellets.
However, this coating process is cumbersome and is often not compatible with feed mill equipment.

example 1

[0251]A powder consisting of:

1.5kgfibrous cellulose, Arbocel BC2000.75kgcarbohydrate binder, Avedex W8011.362kgfinely ground sodium sulphateis granulated in a Lödige mixer FM 50with a granulation liquid consisting of:0.75kgcarbohydrate binder, Avedex W800.3kgwheat starch1.7kgphytase concentrate1.275kgwater

[0252]The granulation is performed in a manner as described in U.S. Pat. No. 4,106,991, Example 1.

[0253]The obtained granulate is dried in a fluid bed to a water content below 1% and sifted to obtain a product with the particle range 250 μm to 850 μm. Finally, the product is coated with 11.5% palm oil and 22% calcium carbonate in a manner as described in U.S. Pat. No. 4,106,991, Example 22.

Abstract

The present invention is related to feed granules comprising a feed enzyme and a zinc salt of an organic acid.

Description

FIELD OF THE INVENTION[0001]The present invention relates to enzyme granules especially for animal feed. The present invention further relates to the manufacturing of said granules.BACKGROUND OF THE INVENTION[0002]In the art concerning animal feed it is a well known fact that pelleting of feed is a desideratum, as pelleting of feed increases the digestibility of especially the starch fraction of the feed. Furthermore, it is known that pelleting of animal feed reduces dust problems.[0003]In the process of producing feed pellets it is considered necessary to steam treat mash feed in order to kill pathogenic micro-organisms if present and to partly gelatinize starch in order to improve the physical properties of the feed, whereby a steam treatment of around 70-120° C. is appropriate. Active compounds present in the feed such as enzymes are not very stable at high temperatures and humidities, and thus, a large surplus of enzymes has to be used, or enzyme free feed components are pelleti...
