Cold-pressed oils as a rich source of polyunsaturated fatty acids and various valuable health promoting compounds, e.g. tocopherols, sterols, squalene, are recommended to be included into diet. An essential limitation to the broad commercialization of these products is their susceptibility to oxidation, which negatively affects safe consumption. In the conducted study 6 commercially available samples of sunflower, rapeseed, pumpkin seed, flaxseed, false flax, blessed milk thistle cold-pressed, non-refined oils were stored at +4 °C for 12 weeks, regularly opened and poured out to simulate real consumers’ storage conditions. The peroxide value, p-anisidine value, iodine value, acid value and colour were determined. The results suggest that refrigerator storage might preserve physicochemical properties of analyzed cold-pressed oils for at least 12 weeks.
