Effects of γ-irradiation on the enzymatic activity of raw pepsin and some saccharated pepsin preparations were studied in the dose range from 0 to 260kGy. The reduction rate of saccharated pepsin preparations has been found to be less than that of raw pepsin. This is due to radiolytic products of lactose in the preparation. Some of the radiolytic products of lactose change their structure with time, so that the product appearing in the early stage seems to be the cause for the overestimation of activity. Therefore, it is recommended that the sample is used after the lapse of two weeks since irradiation when enzymatic activity of irradiated saccharated pepsin preparations is measured by the protein digestive test described in J. P.
