Abstract:
      With peroxide value as an evaluation index, the antioxidant effects of Eleocharis tuberosa peel extracts on edible oils and fats were studied by Schaal oven method.The results showed that the 0.2% Eleocharis tuberosa peel extracts had certain antioxidant effects on lard,soybean oil and rapeseed oil;the antioxidant effect of 0.2% Eleocharis tuberosa peel extracts on lard was weaker than 0.2% ascorbic acid, stronger than 0.2% citric acid and better than 0.2% BHT before 8 d; the antioxidant effects of 0.2%,0.6%,1.2% and 1.8% Eleocharis tuberosa peel extracts on lard had dose-dependent relationship; 0.1% ascorbic acid, 0.1% citric acid and 0.1% tartaric acid could intensify the antioxidant effect of 0.1% Eleocharis tuberosa peel extracts on lard.
