[Quality of the various vegetable oils available on the Polish market].
The aim of this work was the examination of the quality of 17 different vegetable oils (13 refined and 4 extra virgin olive oils) available on the domestic market. The quality of oils was expressed by the following factors: conformity of fatty acid composition that as declared by manufacturer, content of oxidation products (PV, AnV, Totox), content of free fatty acids (LK) and oxidative stability. It was found that 40% of oils did not comply with the requirements concerning oxidative stability. The fatty acid composition of only 1 oil out of 17 investigated did not comply with the declaration by manufacturer. The oxidative stabilities of extra vergin olive oils: 6.44-8.24 hrs., were considerably higher that of other refined oils 2.34 to 8.24 hrs.
