Abstract

Three kinds of different polar solvents were used to obtain Jietan tea extracts by ultrasonic-assisted extraction. A systematic study on antioxidation and frying properties of Jietan tea extracts on edible oil was tested by the Schaal oven method and frying test. The results showed that three kinds of extracts all showed certain antioxidative activities and the best one was the ethanol extract. All extracts were better than synthetic BHT, and some performances such as p-anisidine value 36.55 and acid value 1.22 KOHmg/g were even better than that of synthetic antioxidant TBHQ p-anisidine value of 50.80 and acid value of 1.52 KOH mg/g.

Key words: Jietan tea; extracts; antioxida;
