Abstract

Sweets made with jaggery and peanut (50 : 50) keep for a longer time as compared to the corresponding samples made with sugar. Jaggery suppresses the formation of peroxide in oxidising oils at a concentration between 10 and 50% on the weight of oil. Ethyl ether extracts, 85% alcohol extracts and tannins of jaggery show the peroxidesuppressing effect to varying extent. The major effect seems to reside in the portions insoluble in ether, alcohol and ethyl acetate. Addition of citric acid does not enhance the antioxidant effect of jaggery but antioxidants like B.H.A. and Tenox-II supplement the action of jaggery. The petroleum ether extract of jaggery behaves as a pro-oxidant. Jaggery has been shown to suppress the peroxide formation in oxidised oi l.
