Original language description

Erucic acid, alfa-linolenic acid and brassaicasterol were tested as markers proving the adulteration of sunflower and soybean oils with rapeseed oil. The results of the analyses of plant oils showed that erucic acid can only be used as a marker of such adulteration by massive additions of rapeseed oil. Thereason of this is its low and fluctuating content in oils produced from non-erucic rapeseed (rapeseed oils in quality "00" - averaging 0.4 % of total fatty acids).This was a source of difficulties in cases where low additions of rapeseed oil were determined and the content of erucic acid fluctuated near the detection limit of the analytical method used. Similarly, alfa-linolenic acid can only be used as a supporting marker of the presence of rapeseedoil, due to the permitted range of its content in suflower oil. Brassicasterol appeared as a highly indicative marker, which was lacking in both sunflower and soybean oils, but was found in rapeseed oil, averaging 1400 mg/kg. oybean oils,
