Abstract
The objective of this study was to evaluate the antioxidant capacity of ginger ethanolic extract in soybean oil exposed to the accelerated incubator-storage test. Four treatments were prepared and analyzed by means of accelerated storage test in incubator at 60ºC during 12 days: synthetic antioxidant substance free - refined soybean oil (RSO) (control), soybean oil supplemented with 2500 mg/kg of ethanolic ginger extract – RSO + EG, soybean oil supplemented with 50 mg/kg of synthetic antioxidant substanceTBHQ Terc-butilhidroquinone) – RSO + TBHQ, and soybean oil supplemented with 2500 mg/kg of ethanolic ginger extract and 50 mg/kg of TBHQ – RSO + M. Samples from each treatment were collected at 0, 3, 6, 9 and 12 days of storage, and peroxide index and conjugated dienes were determined. The results from this analytical determination showed that the antioxidant capacity in ethanolic ginger extract decreases according to exposed treatment in the following order: OSR + M = OSR + TBHQ > OSR +EG > OSR.References
