Virgin olive oil was used as substrate to study the influence of chlorophylls on its oxidative stability in light and darkness. Chlorophylls a b were added this substrate, after which oils stored at 36 ± 2°C for three months under artificial (1340 lux) or The effect greater than that additives. prooxidant action presence other pigments not observed assay. During early storage, rate peroxide formation lower samples with chlorophylls, but later it equalled control. In darkness, containing indicating slight antioxidant effect, more marked chlorophyll a.
