Absztrakt (kivonat)

As forecasted by the Intergovernmental Panel on Climate Change (IPCC) of the UN, the World Meteorological Organization, the Hungarian VAHAVA (Change-Effect-Response) project, as well as the National Climate-Change Strategy accepted by the Hungarian Parliament, the expected climate change in the Carpathian Basin will have unfavourably impacts on the Hungarian agriculture, food security and food safety, causing increasing risks of human and animal health. Particular attention should be given to toxigenic moulds and their toxins. Concerning locally grown agricultural crops, the mycological safety of cereal grains, spice paprika, some fruits (apples and grapes) and their processed products might be increasingly contaminated while pistachia, peanuts, cocoa- and coffee-beans represent the main sources of mycotoxin risks of imported commodities. Toxigenic moulds and their toxic secondary metabolic products are important from points of view of both microbiological and chemical food safety, thus, their detection/investigation is one of the main challenges of food analysis in the XXIth century. The mycotoxin problem is of particular importance due to the fact that the mycotoxins are much more resistant to effects of food processing than the microscopic moulds generating them. Thereby products which don’t contain any more viable mould propagulas may still contain mycotoxins. The presence of low concentrations of mycotoxins in food or feed are not recognizable to the consuming persons and animals, while the accumulation of this toxic compounds in the body could cause long term very serious and chronic health problems. A serious difficulty in controlling this sítuation is sampling and sample preparation to obtain representative test portions due to the very uneven distribution of mycotoxins in the most frequently contaminated commodities. Because the time- and labour-intensity of „classical” microbiological and conventional food analytical methods, there is a need for rapid, sensitive, easy-to-use and non-destructive means for detecting moulds and mycotoxins in large number of samples. The paper briefly summarizes analytical methods for determination of mould biomass or detection of mycotoxins in such complex matrices as foods. Such techniques are: impedimetric estimation of mould contamination of food, NIR spectroscopic detection of mouldiness of paprika powder, NIRs estimation of mycotoxins in grains, detection of volatiles of mould-origin by chemical sensor arrays (electronic noses), estimation of various mycotoxins by different high performance chromatographical and immunochemical methods, application of immuno- or nano-sensors utilising the optical waveguide lightmode spectroscopy, or, the surface plasmon resonance method. The correlative instrumental methods must be calibrated first against reference properties and the instrumental data are evaluated with the help of chemometric methods. Related to the last aspect, certain software developments as qualitative classification tools made by Hungarian scientists are pointed out.
