Abstract

For the stability determination of different kinds of edible oils (sunflower, corn and soybean) various methods have been applied: Fluorescent light test, AOM‐method, Oventest and Stability at room temperature. The fatty acid composition, the tocopherol content and the quality characteristics (peroxide value, anisidine value, content of dienes and trienes) were determined before testing of the stability. Special attention has been given to the determination of stability by the Fluorescent light test. This test seems to be very interesting in the determination of oil stability because the action of light is the main factor for the deterioration of the oil, while it is in the supermarkets in clear glass or plastic bottles (oil is not packed in brown glass in Yugoslavia). Oil in 1 liter original glass or plastic bottles or in 50 cm^3^ jars was exposed to the influence of the light of four 40 W fluorescent cool‐white tubes of 1 m. Oxidation rate of the samples was followed by measuring the peroxide value. For the organoleptic evaluation, a three‐member panel judged the flavor on a 10 point scale. The obtained results show that, under the conditions of this test, corn oil has the best stability. Sunflower oil has two and half time better stability than soybean oil. Some correlation has been established between the stability obtained by all applied methods.
