What is Food Additive E223 ?
E223, or sodium metabisulphite, is a chemical compound with the formula Na2S2O5. It appears as a white or yellowish crystalline powder and has a distinct sulfur odor. When dissolved in water, it releases sulfur dioxide (SO2), which is the active agent responsible for its preservative and antioxidant properties.
E223 is a food additive in the category of chemical preservatives. Under acidic conditions, it forms sulfurous acid, which has preservative, oxidizing, and bleaching properties, but also reduces the amount of vitamins in food.

Contraindications and Risks
Despite its benefits, there are some health concerns associated with E223 – sodium metabisulfite:
- Allergic Reactions: Some individuals may experience allergic reactions to sulfites, including E223. Symptoms can range from mild (such as skin rashes and hives) to severe (such as asthma attacks and anaphylaxis).
- Gastrointestinal Issues: Ingesting large quantities of E223 can lead to gastrointestinal discomfort, including nausea, diarrhea, and abdominal pain.
E223, sodium metabisulphite, is a valuable additive in the food industry, known for its preservative and antioxidant properties. While it offers significant benefits in terms of extending shelf life and maintaining food quality, it is essential to be aware of its potential health risks, particularly for individuals sensitive to sulfites.
Considering the potential allergic reactions associated with its use, proper management and adherence to guidelines ensure that sodium metabisulphite remains a beneficial and effective compound in many applications.
