Abstract
Effects of cis/trans free fatty acids on oxidative stability in riboflavin and chlorophyll photosensitized oil-in-water (O/W) emulsions were determined using analysis of depleted headspace oxygen and lipid hydroperoxide contents. Addition of cis/trans fatty acids significantly (p<0.05) accelerated consumption of headspace oxygen and formation of lipid hydroperoxides in O/W emulsions, compared with controls, indicating prooxidative properties of free fatty acids. Cis oleic acid is a more prooxidative factor than trans elaidic acid based on consumption of headspace oxygen under riboflavin photosensitization, while trans elaidic acid acted as a prooxidant for lipid hydroperoxides. Emulsions with oleic and elaidic acids under chlorophyll photosensitization did not show significant (p>0.05) changes in headspace oxygen and lipid hydroperoxide contents after 24 h of treatment. Prooxidative properties of free fatty acids in O/W emulsions were influenced by types of photosensitizer and assay.
