[Autoxidation rate increase of linoleic acid in the presence of tocopherol in aqueous medium ; study of the transformation of tocopherol].
Linoleic acid in aqueous emulsion is spontaneously autoxidized and product hydroperoxides. In vitro the autoxidation of the cis-9, cis-12, octadecadienoic acid with DL-alpha-tocopherol, both emulsified in water, shows an important increase of the hydroperoxides. During this time the tocopherol quickly disappears.
