Study of the behavior and properties of frying oil on repetitive deep frying.

ABSTRACT: The current work focused on the effect of repetitive frying on the physicochemical characteristics of palm oil (PO)and sesame oil (SO) during the preparation of french fries by deep fat frying. A total of 16 frying cycles were carried out and the effect on various parameters was evaluated. The repetitive frying caused higher damage to sesame oil as compared with PO as observed from changes in FFA and PV which increased to 0.63 ± 0.12, 1.31 ± 0.16%, and 2.71 ± 0.02, 7.21 ± 0.01 meq/kg from an initial value of 0.28 ± 0.00, 0.93 ± 0.16% and 0.19 ± 0.00, 0.71 ± 0.00 meq/kg for PO, SO respectively. The fatty acid composition of SO showed significant change with a decrease in linoleic acid and oleic acid content from 42.7 ± 0.01 to 28.1 ± 0.03 and 36.2 ± 0.01 to 25.1 ± 0.01 after 16 frying cycle
