E224 - Potassium Metabisulfite

Potassium metabisulfite (E224) is a food additive primarily used as a preservative.

Use: Potassium metabisulfite is used as a preservative in the food industry. It acts as an antioxidant and helps prevent the oxidation of food, thereby extending its shelf life. It is commonly used in preserving dried fruits, dehydrated fruits, wines, and beers.

Origin: Potassium metabisulfite is synthetically produced. It is derived from sulfur dioxide, a chemical compound with antioxidant properties.

Packaging: Potassium metabisulfite is generally available in the form of white powder or crystals. It is packaged in airtight containers, often in opaque containers to protect the product from light.

Precautions and Safety:

• Handling: It is recommended to handle potassium metabisulfite with care, wearing personal protective equipment such as gloves and safety goggles.
• Storage: It should be stored in a dry, well-ventilated place, away from light. Avoid contact with incompatible substances.
• Food Use: While widely used as a food preservative, some individuals may be sensitive to sulfur dioxide, and excessive consumption can trigger allergic reactions. Therefore, it is important to adhere to regulatory usage limits.
• Regulation: The use of potassium metabisulfite in the food industry is regulated.
