چکیده
RESUMO: O trabalho teve como objetivo avaliar o potencial antioxidante do extrato de Curcuma longa L. na estabilidade oxidativa óleo soja. Para isso, os tratamentos Controle (óleo soja), TBHQ100 soja com 100 mg TBHQ/kg), Extrato100 β-caroteno extrato/kg) e TBHQ50+Extrato50 50 TBHQ/kg + foram submetidos ao teste acelerado em estufa (60 ºC/20 dias). apresentou 51,17% atividade pelo método DPPH• 98,74 μM Trolox.g-1 FRAP, além 457,9 μg β-caroteno.g-1. Embora, inicialmente, todos tenham apresentado baixos valores índice peróxidos (0,55-0,65 meq.kg-1), 20 dias, mostrou maior degradação oxidativa, 46,15 meq.kg-1. apresentaram menores p-anisidina. Apesar ter (8,25 h), (6,41 h) que (3,86 h). Todos elevadas concentrações isômero γ-tocoferol. sintético provou ser mais eficiente prevenção da reação oxidação natural, visto possui elevado grau pureza. Entretanto, resultados satisfatórios, sendo segundo melhor tratamento capaz reduzir as alterações soja, possibilitando a aplicação para redução concentração sintético.
 PALAVRAS-CHAVE: Atividade antioxidante, Carotenoides, Tocoferóis.
