This study was carried out to investigate the effects of roasting conditions on initial Peroxide Value(PV) and Free Acidity% (FA) content of sesame oil. The recorded minimum and maximum PV were 3.9 and 15.4meq KOH/kg oil, while FA was 0.12 and 0.82% as oleic acid, respectively. The PV and FA increased duringstorage for 5 weeks.
