Sodium Metabisulfite

Sodium Metabisulfite:

Sodium metabisulfite is a widely used food additive, often designated by the code E223 in the European Union's food additive classification system. It is also known as sodium bisulfite or sodium disulfite.

• Function: Sodium metabisulfite is primarily used as a preservative in the food industry. It acts as an antioxidant and antimicrobial agent to extend the shelf life of food.

Applications:

• Preservative: It is used in various food products, including dried fruits, fruit juices, wines, canned vegetables, beer, and other products where preserving color and preventing microbiological deterioration are important.
• Antioxidant Properties: Sodium metabisulfite helps prevent food oxidation, which can alter its color and flavor.
• Possible Reactions: Some individuals may be sensitive to sodium metabisulfite, leading to allergic reactions in certain people. These reactions are more common in asthmatic individuals.
• Labeling: When used in food products, sodium metabisulfite must be listed in the ingredient list on the label. In Europe, its E223 code can also be used.
• Usage Limits: Regulatory authorities set limits on the use of sodium metabisulfite in foods to ensure consumer safety.
• Alternatives: Due to allergy concerns, some people prefer to avoid foods containing sodium metabisulfite. In such cases, alternatives can be explored.
