Effects of chlorophyll and visible light exposure on the volatile formations and headspace oxygen content werestudied in lard model systems at 55oC. Samples with or without addition of chlorophyll under light underwent photosensizationor photooxidation, respectively. Total volatiles (TI) in lard with 5 ppm chlorophyll photosensization were 19 times higher thanthose in visible light photooxidized samples for 48 hr while TI in lard with chlorophyll in the dark were not significantlydifferent from those in photooxidized samples (p>0.05). Headspace oxygen content in photosensitized lard decreased from 21to 15% for 48 hr but that in photooxidized lard or that in lard with chlorophyll in the dark did not change significantly(p>0.05), which indicates that lard system used in this study is a photosensitizer-free model system and the presence ofchlorophyll accelerated the lipid oxidation only under visible light. Oxidation mechanisms of photooxidation with or withoutpresence of photosensitizers under visible light were not the same based on the difference of oxidized volatile profiles andheadspace oxygen depletion.
