Abstract
The POV was used as an index,the influences of temperature,light,TBHQ,BHA,BHT and complex antioxidant on the stability of sunflower seed oil were discussed by Schaal oven-storage test.The results showed that light and temperature could accelerate the oxidation of sunflower seed oil,and the effect of temperature was more conspicuous.The separate effect of TBHQ,BHA or BHT could improve the stability of sunflower seed oil markedly,and TBHQ was the best.Under the same dosage of antioxidants,with the exception of TBHQ the effect of complex antioxidant was better than that of single antioxidant.In addition,a combinations of antioxidants with citric acid had synergistic effect.
