Germination inhibitor of thermostable spore-forming bacteria

An object of the present invention is to provide a germination inhibitor that has a germination-inhibiting effect on heat-resistant spore-forming bacteria but has little bitterness peculiar to sucrose fatty acid esters and does not impair the flavor of food and drink. It is. The above-mentioned problems are solved by using, as an active ingredient, a sucrose fatty acid ester in which 90 mol% or more of the constituent fatty acid is palmitic acid.
