Popis: Changes in the quality of two commercial brands of cooking oil were studied under the frying conditions traditionally used in the Portuguese hospitality trade. Three hundred rissoles were fried at a temperature of 160-170°C for 1 hour. Values of peroxide, p-anisidine, Totox, acidity and total polar compounds were determined. Isomeric cis and trans fatty acids were quantified using CP-Sil 88-packed capillary column via gas chromatography.
