Absztrakt (kivonat)
The model for numerical comparison of the influence of essential oils and herbal extracts on the moulds growth, as exponential function with three parameters (S, A, A), was proposed in this work. The model's basis is the functional relationship of the colony diameter dependent of the time and concentration of essential oils or herbal extracts. Three basical types of inhibition have been defined: inhibition to the Abscissa (IAb), inhibition of the Intensity (Iln), and inhibition to the Asymptote (lAs). The practical aplication of proposed model was done according to the results obtained after examination of the influence of different concentrations of Allium ampeloprasum (elephant garlic) essential oil on the growth of food spoilage causing moulds Aspergillus tamarii, Penicillium griseofulvum and Eurotium amstelodami. Function parameters of antifungal activity were calculated in view of 16-days time series of colony diameters, with 0, I, 4, 7, 10 and 15% v/v essential oil of A. ampeloprasum. All obtained functions have high coefficient of correlation. By comparison of parameters of obtained exponential functions, the activity of A. ampeloprasum essential oil to the Aspergillus tamarii, Penicillium griseofulvum and Eurotium amstelodami is numerically comparable. The defined functions could be used in matrix of inhibition and optimization of activity time and minimum inhibitory concentracione (MIC time) of antifungal agens.
