How much lower the system is may be related to the level of completion to which the reaction is carried. Surprisingly, as pointed out by Nojeim (56), the study of reduction potentials as possible predictors of the chemical fate of iron in food has largely been neglected. In fact, literature discussing any effects of redox potential on food chemistry is sparse. Most of... 

Nojeim et al (utilized an electrolytic cell model system, free of oxygen, buffered with phthalate to pH k.2 and designed to provide a redox potential between +300 and +650 mv to evaluate the effect of redox potential on the ionization and valence of four iron compounds El, FS, FOP, and SFEDTA, described previously (1+3.). Data obtained were used to predict ionization and valence trends in actual food systems of different redox potentials. Redox potential was found to have no significant effect on the ionization of any of the four compounds evaluated. However, in the case of El and FS lower potentials in the environment favored the reduced form of iron. This is to be expected since a greater difference between the +770 mv potential of the ferric to ferrous couple and the potential of its chemical environment would cause the reduction to be more spontaneous.
