Resumo

This study evaluated the protective effect of ground aroeira (Schinus terebinthifolius Raddi) fruit addition against fatty acids and cholesterol oxidation in model systems containing sardine oil (Sardinella brasiliensis) during heating (150 and 180 degrees C). High temperatures reduced the amount of essential polyunsaturated fatty acids and caused the formation of oxidized products. Total cholesterol oxides content increased from 58.9 +/- 0.26 to 577.5 +/- 2.14 mu g/g oil, after heating at 180 degrees C. However, aroeira significantly protected lipids from oxidation. Although the synthetic antioxidant applied as standard (butylated hydroxytoluene) showed greater results, it was used in the maximum concentration permitted by Brazilian legislation (0.01%), suggesting that aroeira fruit could be used as a natural antioxidant for the food industry. The protective effect of aroeira may be correlated to its antioxidant capacity and the presence of bioactive compounds which were identified by UHPLC-ESI-MS in the aroeira extract. (AU)
