Due to its conjugated system of double bonds, β-carotene is susceptible to isomerization and degradation during processing. Unfortunately, β-carotene cis-isomers have a decreased provitamin A activity and an altered antioxidant activity (Schieber and Carle, 2005). Furthermore, although some of the first oxidation products of β-carotene (e.g., apocarotenals) are suggested to be biologically active as anticancer agents (Sharoni et al., 2012), complete degradation of β-carotene results in a complete loss of its healthrelated properties (Rodriguez-Amaya, 2001).
