u201c wiped 100 times u201d experiments were performed to examine which of glasses prepared by coating with the enzyme together with a gel matrix in the same manner as described in example 3 or by adding a different hydrolase other than the lipase exhibits more excellent performance to decompose various contaminants three kinds of samples including a sample prepared by adding a lipase alone a sample prepared by adding an amylase with a lipase and a sample prepared by adding a protease with a lipase were prepared to confirm a degree of removal of each contaminant by measuring a haze value a contaminant prepared by mixing oil and starch was transferred and then the change in haze with time was observed the results are shown in fig9 a contaminant prepared by mixing oil and the white of an egg was transferred and the change in haze with time was observed the results are shown in fig1 according to the two experiments it was confirmed that the performance of removing the mixed contaminants was improved when another hydrolase was added with the lipase compared to when the lipase alone was added from the result it was seen that the present invention.
