Oxidative decay of oil is causing changes in its chemical, sensory and nutritional properties and is considered a major problem effecting loses in quality and nutritional value. This paper investigated the influence of the Lamiaceae plant extracts addition on oxidative stability of fish oil. The test was performed under accelerated oxidation by Rancimat method where different concentrations of herb extracts (basil, thyme and oregano) as well as effect of different temperatures were studied.
