Technical Abstract: Tyrosol and hydroxytyrosol are the antioxidant molecules abundantly found in olive oil. Transesterification of tyrosol and hydroxytyrosol with cuphea oil results in medium chain alkyl esters with antioxidant properties. Membrane partitioning, antioxidant capacity, and membrane location of these novel lipids were measured within phospholipid liposomes. Findings demonstrate that both novel lipids partition well within the membrane, possess similar antioxidant characteristics as their parent molecule, and position themselves as typical aliphatic lipids. Our findings demonstrate that these two novel antioxidant lipids may serve as food additives that prevent spoilage through oxidation of fats and oils.
