The active antimicrobial substances used according to the invention are one or more sugar fatty acid esters, the monoester content of which must be at least 30%. The fatty acid component of the active substances is formed by one or more, saturated or unsaturated fatty acids having 6-22 carbon atoms, which fatty acids are straight-chain or branched and also can contain one or more hydroxyl groups. The sugar component of the active substances is, for example, sucrose, glucose, fructose, sorbitol or a mixture thereof.
