    I would suspect if ozone where used to treat a product already having
    sulfite in it that the sulfite would simply be oxidized to sulfate and
    that's it.
    I suppose there could be some interactions with the bound sulfite and or
    thiosulfates that could cause some off odors etc.
    but my best guess would be most of the sulfite would simply be converted to
    sulfate

    Dear listers,

    Does anybody have any information about the use of ozone to disinfect the
    water for the shrimp Head On process. I would like to be sure that it is no
    risk of interaction between the oxidative action of the ozone and the
    anti-oxidative action of the metabisulfite?

    Thanks very much
