Effects of natural catalysts, isothiocyanates and polysulfides, on Z-isomerization and decomposition of (all-E)-carotenoids (lycopene, β-carotene, astaxanthin) following heat treatment were investigated. When isothiocyanates were added to (all-E)-carotenoid solutions and heated, Z-isomerization and decomposition of carotenoids were enhanced, and the degree differed depending on isothiocyanate type. Interestingly, when polysulfides were applied in the same manner, in addition to promoting the Z… Expand

Lycopene inhibits the isomerization of β-carotene during quenching of singlet oxygen and free radicals.
Lycopene protected β-carotene against isomerization during reactions with singlet oxygen and radicals, which can explain the pattern of carotenoid isomers analyzed in fruits and vegetables, where lycopene containing samples showed higher (all-E)/(9Z)-β- carotene ratios, and also in in vivo samples such as human blood plasma.
