Product Description

With the chemical formula Na2S2O5, sodium metabisulfite powder is often referred to as sodium pyrosulfite or sodium disulfite. It has a distinct sulphur scent and is a white, crystalline powder. Due to its abilities as a reducing agent, preservative, and antioxidant, sodium metabisulfite is frequently employed in a variety of industries and applications.


Here are a few typical purposes and uses for sodium metabisulfite powder:

1. Food and beverage industry: Sodium metabisulfite is used as an antioxidant and food preservative to stop yeast, fungus, and bacteria from growing in food and beverages. Wines, juices, dried fruits, and pickled foods can all have their shelf lives extended with the use of this technique. 

2. Water treatment: To remove chlorine and chloramine from tap water, sodium metabisulfite is used in the procedure. It functions as a dechlorinating agent and aids in lowering these disinfectants' concentrations.

3. Photography: Sodium metabisulfite is a crucial ingredient in developing solutions for cameras. It is used to stabilise the developing chemicals and stop oxidation, ensuring optimum film development.

4. Textile Industry: Sodium metabisulfite is a reducing agent used in the dyeing and printing processes of textiles. It improves the colorfastness of materials and aids in the removal of extra dye.

5. Industry of pulp and paper: Sodium metabisulfite is employed as a bleaching agent in the industry of pulp and paper, particularly for the treatment of mechanical pulps. It assists in lightening the pulp and lowering lignin levels.

6. Pharmaceutical Industry: Pharmaceutical formulations occasionally contain sodium metabisulfite as an excipient or a component. In some medicines, it can function as an antioxidant, stabiliser, or reducing agent.


It's crucial to remember that sodium metabisulfite might induce allergic reactions in some people, especially those who have asthma or sulfite sensitivity. It should be handled carefully and in accordance with the appropriate safety regulations and recommendations, just like any other material.
