In fresh fruits and vegetables, O2 is the main causative agent for ill-defined biochemical changes leading to loss of flavour and colour. Lipoxygenases have been demonstrated to be responsible for these changes. In this study, the ability of lactic acid bacteria metabolites to inhibit lipoxygenase activity was studied. An inhibitor of plant lipoxygenase from culture filtrates of Lactobacillus casei was purified by column chromatography and shown to be benzoic acid. The isolated compound had an IC50 of 350muM against purified soybean lipoxygenase at pH 9. Results indicate that L. casei may have the potential to be used as a preservative against the oxidation of unsaturated fatty acids, thereby preventing development of undesirable flavours in foods.
