This figure shows that at most wine and beer pH levels, SO 2 is predominantly in the bisulfite ion form, with a higher fraction of molecular SO 2 as pH declines.. Mathematically we can calculate the amount of molecular SO 2 based on the measured free SO 2 and pH: [Molecular SO 2] = [Free SO 2] / ( 10 (pH - 1.81) + 1 ) . Note that the pK 1 value for sulfite is generally accepted as 1.81 for ...

PRESERVATIVES

Sulphiting uses sulphite salts such as sodium or potassium sulphite or metabisulphite. The fruit or vegetable is either soaked in a sulphite solution or, if the commodity is being blanched in water, sulphite can be added to the blanching water. Adding sulphite to the blanching water is attractive since it combines two operations into one.
