In addition, by preference, the composition may contain, furthermore, at least a second food-grade preservative additive with antifungal properties selected from the group of polyene macrolides. A further subject matter of the present invention is the application method for the composition in order to control environmental fungal growth, principally at food-industry facilities for producing, storing, drying and/or curing foods such as, for example, cheese, ham and sausages.
