Abstract

A process is presented for producing stable multi-enzyme containing granules. The process involves the steps of mixing a reversible competitive inhibitor with a first enzyme, adding a second incompatible enzyme, adding a carrier, extruding and granulating the resulting mixture and reducing the moisture content if necessary.
