text: Based on the consideration that the immobilization of glucanase may lead to a reduction in activity change with time, it is presumed that, if glucanase is immobilized with apatite used as the polishing agent for dentifrice by the physical adsorption method, immobilized glucanase might be obtained easily and it might then be possible to obtain a desirable dentifrice material which combines a polishing capability with a polysaccharide-decomposing capability, and dispenses with any selection of stabilizer.
