PURPOSE: To store food, drink and feed for a long period without impairing quality and taste by suppressing growth of heat-resistant bacteria in food, drink and feed or killing these bacteria. ;CONSTITUTION: An agent for suppressing growth of heat-resistant bacteria containing a hydrolase, preferably a proteolytic enzyme, especially (a) an exo type proteolytic enzyme or (b) an endo type proteolytic enzyme, each produced by a microorganism belonging to Rizopus-hangchow or (c) a prepared enzyme having 1:1 to 100:1 activity ratio of the ingredient (a): the ingredient (b) as an active ingredient. The agent for suppressing growth of heat-resistant bacterium has an effect for suppressing growth of the heat-resistant bacteria originated in a raw material of food, drink and feed or mixed during the production process or during storage of the product or sterilizing the heat-resistant bacteria and is especially useful for killing the heat-resistant bacteria of food and drink packed in heating part of automatic bending machine. Furthermore, a blending amount of the agent with food, drink and feed is preferably 0.01-0.5W/W% based on total solid content as the active ingredient.;COPYRIGHT: (C)1993,JPO&Japio
