Sažetak
Fats as the main energy source are an important part of the diet. Extra virgin olive oil (EVOO) has special value among fats thanks to its composition, especialy monounsaturated fatty acids and minor components (phenolic compounds, tocopherols, and carotenoids), which are associated with health benefits. Therefore it is a vital part of the Mediterranean diet. EVOO production is demanding, but storage is an even greater challenge. Due to high levels of unsaturated fatty acids, EVOO is prone to lipid oxidation generating lipid peroxides, potentially toxic compounds that can cause cellular damage. The Dalmatian region is the largest olive oil producing area in the Republic of Croatia. Over the years it has become an increasingly important tourist center. Therefore, apart from being an important food product, EVOO becomes an important part of tourism promotion. For this reason, during two tourist seasons (May-September 2021-2022), samples were collected at local markets where the local population, as well as visitors, usually shop. In 37 samples, quality parameters were analysed in accordance with Regulation 2568/91 [peroxide value, free fatty acid (as oleic), apsorbance in UV area, ethyl esters, waxes, as well as stigmastadienes]. Analyses were performed using standardized and accredited methods. The results are extremely worrying considering that 73 % of the samples did not meet the requirements of the Regulation. Analysing the results that indicate a high degree of oxidation and adulteration, it is clear that there can be no question regarding the beneficial effect of EVOO ; in fact, quite the opposite is true.
