    Sodium Metabisulfite effects fading function by addition reaction of sulfite. So as to achieve the purpose of bleaching.

This action is reversible, sulphurous acid can be removed by heating or acid treatment, to make anthocyanin regenerate and resume the original red.

     

     

    Sodium Metabisulfite is widely used in food industry. Besides bleaching effect, Sodium Metabisulfite also owns the following functions:

    1) Sodium Metabisulfite in food has anti-browning effects. 

    2) Sodium Metabisulfite in food has antiseptic effect.  

    3) Sodium Metabisulfite in food has loosen machine effect, Sodium Metabisulfite can be used as the constituent of loosen machine.

    4) Sodium Metabisulfite in food has oxidation resistance effect.  

     

    The mechanism Sodium Metabisulfite effects: Decolorizers can be divided into two types by its function: oxidation type bleaching agent & reducing type bleaching agent. Sodium Metabisulfite belongs to reducing type bleaching agent.
