Introduction

Sodium metabisulfite is a chemical compound with the formula Na₂S₂O₅. It is widely used as a food additive and preservative due to its antioxidant and antimicrobial properties. Sodium metabisulfite is often employed in the food industry to prevent spoilage, maintain freshness, and enhance the color of various products.

Applications of Sodium Metabisulfite

1. Preservative: It effectively inhibits the growth of bacteria, yeasts, and molds, making it valuable for prolonging the shelf life of various food products, including dried fruits, wines, and some canned goods. It helps to prevent spoilage and maintain the quality of these items.

2. Antioxidant: Sodium metabisulfite acts as an antioxidant, preventing the oxidation of food components that can lead to rancidity and loss of flavor. This property is particularly important in products containing fats and oils.

3. Color Retention: In fruits and vegetables, sodium metabisulfite is used to preserve color and appearance. It helps to prevent browning reactions that can occur in products like apples, bananas, and potatoes when exposed to air.

4. Wine Production: In winemaking, sodium metabisulfite is commonly employed to inhibit unwanted microbial growth and oxidation, ensuring the quality and stability of the wine.

5. Baking Industry: It can be used as a dough conditioner in bread production, improving the texture and shelf life of baked goods.
