Abstract
The isomerase activity of a dry isomerase preparation (e.g., glucose isomerase) is enhanced by initially pretreating the isomerase in an aqueous solution which contains an activating amount of a metal ion activator and/or a thiol generating reducing agent and/or a monosaccharide which the isomerase is capable of isomerizing. Pretreatment temperature and time periods are most suitably conducted in such a manner so as to minimize isomerase deactivation. The pretreatment increases total isomerase activity and thereby renders it more effective for use in an isomerization process (e.g., glucose isomerization).
