COATED ENZYME GRANULES.

摘要

The present invention relates to coated enzyme granules and a method of preparing coated enzyme granules including the steps of (i) contacting enzyme granules with a coating material which is either (a) a non-aqueous liquid or aqueous emulsion thereof, or (b) an unctuous mixture comprising at least one liquid as in (a) having dissolved therein a second component having a melting point in the range 30 to 90 °C, said contacting being carried out so as to provide a substantially uniform coating on said granules of said coating material at less than 25 wt.percent, and (ii) contacting the granules formed in step (i) with an anti-caking agent so as to obtain free-flowing granules having a dust figure of less than 2 'mu'g as determined by the Heubach attrition test.
