Abstrakt: Oxidative stability of the purified common Kilka triacylglycerols ( PKO) as affected by 1-8% w/w of bene kernel ( BKO) and hull ( BHO) oils was studied and compared with that of 100 mg kg−1 of BHT and α-tocopherol. Lipid oxidation was measured by monitoring peroxide value till the minute 80 ( PV80, meq kg−1) and also by determining the oxidative stability index at 60 °C ( OSI60, h). In the Rancimat test, the OSI60 of the PKO (1.66 h) was significantly increased by some of the added antioxidants, and the BKO 8% (7.98 h) had the highest antioxidant activity with no significant differences among the BHT, α-tocopherol and the BHO 8%. Furthermore, an exponential regression curve with a good coefficient of determination (R2 > 0.94) was observed between the changes in the PV80 and OSI60 values of the PKO. [ABSTRACT FROM AUTHOR]
