Testování antifungální aktivity obalových materiálů s rostlinnými extrakty

This diploma thesis deals with testing of antifungal activity of packaging materials with plant extracts. First part is a literature review, consisting of three chapters. First chapter contains basic characteristics of filamentous fungi and their metabolic products. Second chapter describes properties of packaging materials used in the food industry with a focus on active packaging. Last chapter of the literature review discusses the essential oils of plants. There are described the properties of essential oils, chemical composition and samples of plants from which the essential oils are most often obtained. The practical part of this thesis deals with the microbiological analysis of selected food stored in the packaging with active foil. This foil was enriched by spray with a mixture of plant extracts. The aim of this experimental determination was to find out if the active foil has an antifungal impact. Tested microorganism was Penicillium chrysogenum
