An immobilized enzyme product is produced by contacting an inert particulate support with an aqueous enzyme solution containing preferably at least 25% dissolved solids and with a water miscible organic solvent, and crosslinking the enzyme to insolubilize the enzyme on the support as a gel containing 50-90% water. The water miscible organic solvent is in substantial excess of the amount of water mixed with the support in the process. The solvent may be contacted with the support before or after contacting with the enzyme solution. The resultant immobilized enzyme product has a bulk volume 5 to 300% greater than the bulk volume of the support material. A least a portion of the gel is external to the support and constitutes at least 3% by volume of the immobilized enzyme product.
