Potassium bisulfite

Potassium bisulfite is a white, crystalline solid with a slight sulfur dioxide odor; it is hygroscopic and decomposes upon heating without a sharp melting point, releasing SO₂ gas. It is an inorganic salt and a source of sulfite/bisulfite ions, commonly used as a reducing agent and preservative. Its primary industrial applications include food preservation (e.g., wine and fruit juice stabilization), water treatment (as a dechlorinating agent), and as a sulfonating or reducing intermediate in the synthesis of dyes, pharmaceuticals, and organic chemicals. It is also employed in photographic developing solutions and textile processing.

Potassium Hydrogen sulfite is a preservative that retards bacterial action, prevents discoloration, and functions as an antioxidant. It is not used in meats or in food recognized as a source of vitamin b1 and it is not used on fruits or vegetables intended to be served raw or presented as fresh.
