摘要

用,60,Co γ辐射对木瓜蛋白酶制剂进行灭菌试验，吸收剂量8 kGy和12 kGy，杀菌率分别达到98.8%和99.9%，酶活力相应地下降26%和32%。在木瓜蛋白酶制剂中加入碘化钾和维生素C时（均为0.1%），经8 kGy剂量照射，酶制剂达到完全灭菌，酶活力下降15%。

Abstract

This paper reports the result of radiation sterilization and the change of enzyme activity of papainase under the action of γ-rays. when KI and vitamin C were added to the papainase, radiation strilized efficiency reached 100%, but enzyme activty reduced 15% at the dose of 8 kGY.
