PURPOSE:To encapsulate enzyme without lowering the activity thereof, by dispersing a liquid mixture consisting of an aqueous solution having a water-soluble polymer dissolved therein and enzyme or an enzyme-containing composition in liquid hydrocarbon and subsequently adding acetone to the resulting dispersion. CONSTITUTION:A liquid mixture consisting of an aqueous solution having a water-soluble polymer constituting a capsule wall dissolved therein and enzyme or an enzyme-containing composition is dispersed in liquid hydrocarbon and acetone is subsequently added to the resulting dispersion to prepare an enzyme- containing microcapsule. As the embodiment of the water-soluble polymer, there are polyvinyl alcohol and carboxy methyl cellulose, etc., and, as the embodiment of enzyme, there are protease, amylase, glucoamylase and liperse, etc. As the liquid hydrocarbon, there are n-hexane, n-heptane, n-octane and liquid paraffin, etc. |
