LUZIA, Débora Maria Moreno  y  JORGE, Neuza. Antioxidant activity of lemon seed extract (Citrus limon) added to soybean oil in accelerated incubator-storage test. Quím. Nova [online]. 2009, vol.32, n.4, pp. 946-949. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422009000400022.

The aim of this work was to evaluate antioxidant activity of lemon seeds added to soybean oil, submitted to accelerated incubator-storage test and to determine its synergistic effect with the synthetic antioxidant TBHQ. The treatments Control, TBHQ (50 mg/kg), LSE (2,400 mg/kg Lemon Seed Extract), Mixture 1 (LSE + 50 mg/kg TBHQ) and Mixture 2 (LSE + 25 mg/kg TBHQ) were prepared and subjected to the accelerated incubator-storage test at 60 ºC for 12 days; samples were taken every 3 days and analyzed regarding peroxide value and conjugated dienes. The results showed that antioxidant activity of the tested treatments were: TBHQ = Mixture 1 = Mixture 2 > LSE > Control.
