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.
