Abstract:		"In order to study the oxidative stability of hazelnut oil stored at room temperature, hazelnut oil accelerated oxidized at 62 degrees C was used to determine peroxide value (POV), p-anisidine value (p-AV), total oxidation value (TOTOX), the content of fatty acids and volatile oxidative products. The correlation between the content of fatty acids or volatile oxidative products and three peroxidation indexes was analyzed. The results showed that the relative content of linoleic acid in hazelnut oil decreased significantly at the duration of accelerated oxidation (p < 0.05), which was in line with the zero-order oxidation kinetics model. The absolute content of four fatty acids all accorded with the zero-order oxidation kinetics model. Both relative and absolute content of linoleic acid can set up a slightly negative linear correlation with POV, p-AV and TOTOX, respectively (p < 0.05). The oxidation of unsaturated fatty acids in hazelnut oil produced a variety of volatile oxidation products, among which hexanal, 2-octenal, 2-decenal and 3-octene-2-one could establish a significantly positive correlation with POV, p-AV and TOTOX at a certain period of time, which could be used as a new index to evaluate the oxidative decomposition of unsaturated fatty acids in hazelnut oil during storage"
