Abstract
Singlet oxygen produced by photochemical sensitizers may play an impor tant role in the oxidation of lipids in foods. Therefore, we studied t he singlet oxygen oxidation of lipids and the scavenging ability of an tioxidants. Singlet oxygen was generated using the photosensitizer ros e bengal. The oxidation products of lipids and antioxidants were separ ated by high-performance liquid chromatography and monitored using pos t-column chemiluminescence and/or iodometric detection. The competitiv e reaction rates of various antioxidants and lipids were studied to el ucidate the roles played by antioxidants in the prevention of food oxi dation by singlet oxygen.
