Effect of Tween 20 on the Oxidative Stability of Sodium Linoleate and Sodium Docosahexaenoate

Abstract

Sodium linoleate (LA) and sodium docosahexaenoate (DHA) were oxidized in an aqueous phase with or without Tween 20. The oxidative stability of LA with Tween 20 was slightly less than that of LA without Tween 20. In contrast, when DHA was dispersed in a buffer containing Tween 20, the stability of DHA was markedly increased, suggesting a specific effect of Tween 20 on protecting DHA against oxidation in aqueous micelles.
