Sodium Metabisulphite, also known as sodium pyrosulfite, is a food additive that is commonly used in the food and beverage industry for various purposes. Sodium Metabisulphite acts as a preservative and antioxidant by inhibiting the growth of microorganisms such as bacteria, yeasts, and molds. It helps extend the shelf life of food and prevents spoilage. It helps to prevent oxidative reactions in food and beverages, which can cause discoloration, off-flavors, and nutrient loss. Sodium Metabisulphite can reduce the oxidative degradation of certain vitamins and flavor compounds. Sodium Metabisulphite is utilized as a bleaching agent to remove unwanted colors or pigments from food products such as molasses, coconut milk, and fruits. In baking applications, Sodium Metabisulphite can act as a dough conditioner by improving dough texture, stability, and fermentation properties. It is used to inhibit certain enzymatic activities in fruits and vegetables, preventing browning and maintaining their natural color.
