Assessing the Antioxidantive Activities of Four Food Antioxidants by Two Methods

Abstract

Abstract: A study of the antioxidant activities of four antioxidants was carried out by DPPH•method and TBARS method. The results showed the tested antioxidants all could screen the DPPH•and inhibit the lipid pro-oxidation of linoleic acid effectively. The orders of their antioxidant activities were TBHQ>TP>VE>BHT and BHT>VE>TBHQ>TP by DPPH•method and TBARS method respectively. It was worth notice that the different antioxidant activities were associated with the different assays.

Key words: antioxidant, antioxidantive activity, DPPH•, TBARS(Thiobarbituric acid reactive substances)
