The present invention provides a new inhibitor for Bacillus cereus which has been designated officially as a pathogen of food poisoning, which comprises a protamine or its salt as an essential component.

Multiplication inhibitor for Bacillus cereus

A liquid bactericide for foods and food processing machines or utensils, said bactericide comprising as active ingredients 98.0 to 2.3% (W/V) of ethyl alcohol, 1.0 to 96.7% (W/V) of an organic acid selected from the group consisting of lactic acid, acetic acid, citric acid, tartaric acid, gluconic acid, malic acid, ascorbic acid and phytic acid and 1.0 to 96.7% (W/V) of phosphoric acid; said bactericide being capable of sterilizing within 30 seconds when used in an aqueous solution, such that the concentration of active ingredients in solution consists of 14 to 1% (W/V) of ethyl alcohol, 13.0 to 0.3% (W/V) of said organic acid and 0.7 to 0.03% (W/V) of phosphoric acid.

Liquid bactericide for foods and food processing machines or utensils,

An aqueous sterilizing agent for foods or food processing machines and utensils, comprising an aqueous solution containing about 0.5 to 75% by weight ethanol, an alkali carbonate selected from the group consisting of sodium carbonate and potassium carbonate and a trialkali phosphate selected from the group consisting of trisodium phosphate and tripotassium phosphate wherein the combined amount of the carbonate and phosphate is about 0.5 to 40% by weight; and a method of sterilizing foods or food processing machines and utensils, which comprises contacting the foods or food processing machines and utensils with the above aqueous sterilizing agent.
