Sodium and potassium metabisulfite have many major and niche uses. It is widely used for preserving food and beverages.. Sodium metabisulfite is added as an excipient to medications which contain adrenaline (epinephrine), in order to prevent the oxidation of adrenaline. [6]
The compound sodium metabisulfite is used in almost all commercial wines to prevent oxidation and preserve flavor, sodium bisulfite is sold by some home winemaking suppliers for the same purpose. [6] In fruit canning, sodium bisulfite is used to prevent browning (caused by oxidation) and to kill microbes.
The sodium metabisulfite in the Campden tablets will trap oxygen that enters the wine, preventing it from doing any harm. It is a common misconception that Campden tablets can be used to halt the ferment process in wine before all the available sugars are converted by the yeast, hence controlling the amount of residual sweetness in the final ...

[8] Sulfites are implicated in asthmatic reactions and may also cause symptoms in non-asthmatic individuals, namely dermatitis , urticaria , flushing ...
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite is not a real compound, [ 2 ] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
Sulfites are used as a food preservative or enhancer. They may come in various forms, such as: [5] Sulfur dioxide, which is not a sulfite, but a closely related chemical oxide; Potassium bisulfite or potassium metabisulfite; Sodium bisulfite, sodium metabisulfite or sodium sulfite
