Abstract
In this paper, the antioxidative property of sesamol for tea-seed oil was studied by camparing that with BHT( Butylated Hydroxy Toluene ) and VE(Vitamin E). The experimental procedures were carried out as follows. The tea-seed oil with antioxidant was preserved at 60 ℃±2 ℃ for ten days and the POV of the tea-seed oil was determined by iodometry to investigate the antioxidative effect of sesamol on tea-seed oil. The result indicated that the POV of tea-seed oil with 0.10 %(w/w) sesamol was 7.94 mmol/kg at 10th day compared that of 32.16 mmol/kg with black control. It was good as that of BHT and better that that of vitamin E under same concentration(0.01 %-0.10 %, w/w) .
