Sodium metabisulfite, origin and uses


At Rebain International (Spain), S.L., we distribute a wide range of products, including sodium metabisulfite, but what is it and what is it used for?

Sodium Metabisulfite is a food preservative widely used in the food industry due to its antimicrobial and antioxidant properties.

This product manages to prolong the useful life of food by reducing its oxidation, improving its appearance, consistency, flavor and preserving the nutritional value of the product.

Some of the main uses in the food industry are:

1. Preservation of perishable foods such as fruits, vegetables, meat and fish, both in canned products and processed foods.
2. Production of wine and beer, preventing oxidation and stopping unwanted fermentation. In wine, it is also used to stabilize color and aroma.
3. Food supplements and vitamins.
4. Candies.

It is of course also used in the cosmetic and pharmaceutical industry.
