Process for preparing a stabilized, aqueous enzyme dispersion, a stabilized, aqueous enzyme dispersion which is prepared in this process, and a clear solution which comprises an enzyme and a water-soluble polymer for use in the process
A convenient method for preparing a stabilized aqueous enzyme dispersion comprises: (1) precipitating a water-soluble polymer from aqueous solution to form an aqueous dispersion, and (2) before, during or after (1), contacting the dissolved or dispersed polymer with an aqueous solution or fine aqueous dispersion of enzyme. Using this method, substantial improvement of the enzyme stability during storage can be obtained with surprisingly little polymer (relative to enzyme). And enzyme stabilization can, surprisingly, even be obtained by contacting precipitated polymer with dissolved enzyme. The stabilizing effect therefore appears not to be due (or at least not primarily due) to encapsulation.
