Antioxidative Activity of a Cathodic Solution Produced by the Electrolysis of a Dilute NaCl Solution

Abstract

  The effectiveness was evaluated of a cathodic solution prepared by the electrolysis of an NaCl solution in inhibiting the aqueous oxidation of ethyl linoleate and ethyl docosahexaenoate. The decrease in unoxidized substrate and the formation of total peroxides during oxidation indicate that the cathodic solution completely inhibited the oxidation of both ethyl esters, while these lipids were easily oxidized in an NaCl solution and in distilled water. The antioxidative activity of the cathodic solution was confirmed after open incubation for 3 days and 7 days at 37°C, although the scavenging ability of the cathodic solution toward DPPH radicals disappeared during this incubation.
