Resumen
O objetivo deste trabalho foi avaliar a capacidade antioxidante do extrato etanólico de gengibre em óleo de soja, submetido ao teste de estocagem acelerada. Quatro tratamentos foram preparados e submetidos a um teste de estocagem acelerada em estufa, a 60ºC durante 12 dias: óleo de soja refinado (OSR) isento de antioxidantes sintéticos – OSR (controle), óleo de soja adicionado de 2.500mg/kg de extrato etanólico de gengibre – OSR + EG, óleo de soja adicionado de 50 mg/kg do antioxidante sintético TBHQ (tercbutilhidroquinona) – OSR + TBHQ e óleo de soja adicionado de 2.500mg/kg de extrato etanólico de gengibre mais 50 mg/kg de TBHQ – OSR + M. Amostras de cada tratamento foram recolhidas nos tempos 0, 3, 6, 9 e 12 dias de estocagem, e analisadas quanto ao índice de peróxidos e dienos conjugados. Os resultados das determinações analíticas mostraram que a capacidade antioxidante no extrato de gengibre decresce de acordo com os tratamentos utilizados e na seguinte ordem: OSR + M = OSR +TBHQ > OSR + EG > OSR.Citas
