Sodium Metabisulfite and Your Health The powder is highly irritating to skin and tissue and is toxic to inhale, per the NCBI. It’s also corrosive when mixed with water. As a food preservative, sulfites — including sodium metabisulfite — can cause respiratory symptoms for some people, particularly people with asthma
Sodium bisulfite releases sulfur dioxide gas when added to water, killing yeast, fungus, and bacteria, roughly 24 hours before fermentation, when added to wines. It may also be added after fermentation to prevent vinegar production and protect the color and flavor of wine.
As doses of potassium metabisulfite or Campden tablets are added throughout the wine making process, the amount of bound sulfite builds up. If it builds up too much you can actually taste it in the wine.
