摘      要：The activity of lipase was determined by alkaline titration method and the conditions for the determination of lipase activity were studied. The results showed that the lipase activity was stable when the volume fraction of olive oil was 25% and the temperature was at 40℃ with PH=7.5. Under the proper conditions, the effects of anionic and nonionic surfactants were investigated. The effect of nonionic surfactants on the activity of lipase was less than that of anionic surfactants. Finally, the analysis method was used to determine the activity of the lipase in the commercial detergent products. The results showed that the method can be used for the determination of lipase activity in both liquid detergent and laundry powder. However, the temperature and pH value of the detergent solution should be controlled strictly during the conduction of the determination.
