Since TGOOH and its subsequent oxidation products cause not only the deterioration of oil quality but also various toxicities, preventing the oxidation of edible oils is essential.

Great differences in the headspace compositions of both samples were found due to the different oxidation levels reached.

The aim of this work was to determine the level of contamination of different groups of vegetable oils available on the Polish market with polycyclic aromatic hydrocarbons, i. The research materials were refined rapeseed oils, sunflower oils, olive pomace oil, rapeseed oils with olive oil and unrefined soybean and coconut oils. The research methods included process of saponification of the vegetable oils, extraction of the polycyclic aromatic hydrocarbons fraction, clean-up by use a column packed with aluminum oxide and elution by petroleum ether, and then quantitative and qualitative determination of by high performance liquid chromatography with fluorescence detection method. Values of limit of detection and limit of quantification obtained during validation of the method were 0. The highest polyaromatic hydrocarbons content was found in unrefined coconut and soybean oils. Vegetable fats are recognized as important components of the human diet.

    A gas chromatography-mass spectroscopy GC-MS method was developed to assess the infant exposure assessment from four important polycyclic aromatic hydrocarbon PAH markers in infant formula powder: benzo[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene collectively referred to as PAH4.

    In vegetable oils, the isolation of the hydrocarbon fraction is usually performed by means of alkaline hydrolysis of the oil sample [19]. The.
