[Determination of Alternaria mycotoxins in selected raw and processed fruit and vegetable products].
The purpose of the study was the assessment of Alternaria-mycotoxins contamination in some raw and processed plant products. The analytical method for detection of alternariol (AOH) and alternariol methyl ether (AME) is described. After extraction and purification of sample crude extracts by column chromatography on silica gel, the qualitative and quantitative analyses were carried out by two-dimensional TLC. There were 110 samples analyzed -44 (included 32 moulded) raw plant samples and 56 processed plant products. Levels of alternaria-mycotoxins found in fruits and tomatoes visibly decayed ranged between 3 to 420 micrograms/kg for AOH and 10 to 100 micrograms/kg for AME. Trace amounts of AOH were detected in 3 samples of processed products.
