HYDROGEN PEROXIDE
Prepared at 63rd JECFA (2004) and published in FNP 52 ADD 12 (2004) superseding specifications prepared at the 29th JECFA (1985), published in FNP 52 (1992). No ADI was allocated by the 24th JECFA (1980) with comment "may be used only where better methods of milk preservation are not available". Small residues of hydrogen peroxide on food (which has been treated with antimicrobial washing solutions) at the time of consumption would not pose a safety concern (63rd JECFA, 2004).
DEFINITION The principal method for the manufacture of hydrogen peroxide is the catalytic reduction by hydrogen of a substituted anthraquinone dissolved in a mixed aromatic hydrocarbon solvent, to anthraquinol. The hydrogenation catalyst is removed and the anthraquinol solution is subjected to aerial oxidation, to yield anthraquinone and hydrogen peroxide. The anthraquinone is recycled and the hydrogen peroxide, extracted with water, is purified and concentrated. The dilution of the concentrate is adjusted and a tin based stabilizer added.
