PURPOSE:To obtain a stable modified protease composition, excellent in thermal and preservation stabilities and useful as a cosmetic, a detergent, a medicine, etc., by adding calcium to a modified protease prepared by binding a protease to polysaccharides through a triazine ring. CONSTITUTION:This composition is obtained by reacting polysaccharides with cyanuric chloride, further reacting the resultant active polysaccharides with a protease and adding a trace amount of calcium to the prepared modified protease. The obtained composition is stable even in a wet state and capable of manifesting the stability even when dissolved in an aqueous medium without causing the turbidity or precipitates even in aspects of properties as a product. The calcium is added in an amount of preferably about 0.01-1wt.%. |
