In combination of free radical
scavenger and metal chelator, the chelator decreases the oxidation rates
by inhibiting metal-catalyzed oxidation; resulting in, fewer free
radicals generated in the system. Inactivation of antioxidants via
termination reaction or participation in autoxidation occurs to a lesser
extent in such situations. The concentration of antioxidant, available
to scavenge free radicals, will always be greater at a given time than
when no metal chelator is present. The combination of chelator and
radical scavenger decreases free radical generation and increases
radical scavenging potential . Synergistic activity has been observed in
the mixtures of natural tocopherols and citric acid. The synergistic
effect of this mixture is caused by the chain-breaking ability of
tocopherols and metal chelation of citric acid .
