  abstract = {{T}he kinetics of trans-beta-carotene and trans-lutein degradation were individually investigated in palm olein and {V}egetaline ({R}), at four temperatures ranging from 120 to 180 degrees {C}. {HPLC}-{DAD} analysis was carried out to monitor trans and cis carotenoid variations over the heating time at each temperature. {I}n both oils, initial trans-beta-carotene and trans-lutein degradation rates increased with temperature. {T}rans-lutein was found to degrade at a slower rate than trans-beta-carotene, suggesting a higher thermal resistance. {T}he isomers identified were 13-cis- and 9-cis-beta-carotene, and 13-cis-, 9-cis-, 13'-cis-, and 9'-cis-lutein. {I}n spite of the higher number of lutein cis isomers, their total amount was lower than that of beta-carotene cis isomers. {T}rans and cis carotenoids were involved in degradation reactions at rates that increased with temperature. {A}ll degradation rates were generally found to be lower in {V}egetaline ({R}) than in palm olein. {T}hese results were explained by the initial composition of the two oils and especially their peroxide and vitamin {E} contents.},
