Abstract
Methods for use of select organic compounds for the activation and stabilization of thermally labile enzymes, including proteases, are disclosed. The invention further relates to compositions of certain organic compounds with enzymes to enable the use of such enzymes at high temperature conditions, such as for warewash temperatures and conditions. In particular, organic activator-stabilizers including heat-deactivated proteases and zwitterionic materials are combined with enzymes according to the invention. As a result, the invention provides enzyme cleaning efficacy for various high temperature conditions, including warewash applications.
