Abstract
This study was performed for assessing the antioxidant activity of different concentrations of coriander extract and of ascorbyl palmitate, in order to determine those most efficient amounts to be added into sunflower oil. Coriander extract in concentrations of 400, 800, 1,200, 1,600 and 2,000 mg/kg, and ascorbyl palmitate in concentrations of 100, 200, 300, 400 and 500 mg/kg were added into sunflower oil. The antioxidant activity of each concentration was evaluated through oxidative stability using Rancimat equipment, and the concentrations were determined by polynomial regression. The concentrations of 1,600 mg/kg of coriander extract and 500 mg/kg of ascorbyl palmitate were those that presented the best oxidative stability for sunflower oil. The coriander extract and the ascorbyl pamitate showed a positive effect in promoting oxidative stability, which make them an alternative choice for preserving vegetal oil.References
