Atmospheric oxidation of ascorbic acid in nonionic surfactant systems

In our study we investigated the kinetics of atmospheric oxidation of ascorbic acid in the aqueous solutions of two non-ionic surfactants TRITON X-100 and commercial sugar ester C1616 (the most suitable emulsifier for food). For each surfactant the concentrations below and above the CMC were investigated. It was found that the micellar solutions of both surfactants showed faster oxidation rate than pure water. Less pronounced effects were observed with particular surfactant concentration change.
