Reaction of hydrogensulfite ion (HSO3-) by the dissolved oxygen (O2) in aqueous solution was remarkably enhanced under the freezing process, in which hydrogensulfite ion was changed to sulfuric ion (SO42-). When the concentration of hydrogensulfite ion was fixed at 2.0×10-4moldm-3, the time profile of pH value was reduced 6.0 to 4.5 under the freezing process, in which the change of acidity was accelerated to the later stage in freezing.
