MORENO ALVAREZ, Mario José et al. Evaluación de la actividad antioxidante de extractos de flavonoides de cáscara de naranja en el aceite de soja desodorizado . INCI [online]. 2004, vol.29, n.9, pp.532-538. ISSN 0378-1844.

The antioxidant activity of aqueous and organic flavonoid extracts from orange peels was evaluated. Orange peels were transformed into flour and flavonoids were extracted employing flour/solvent ratios of 1/2, 1/1.33 and 1/1. Final extracts were dried at reduced pressure in a rotaevaporator at 60ºC. Dry products were dosed to deodorized soybean oil in the proportions 0.01, 0.05 and 0.10%. Then, the samples were placed in an air stove at 60 ±1ºC and every 24h peroxide was determined until a maximum value of 100meq O₂/kg. The largest antioxidant activity was found with the 0.10% aqueous extract (P<0.05).
