In plain language

A synthetic preservative that prevents oxidation and microbial growth, primarily used in wines and some fruit-based products. It releases sulphur dioxide, which is the active preserving agent. People with asthma or sulphite sensitivity can experience breathing difficulties, skin reactions, or digestive upset. Authorised in very few food categories — a sign regulators apply caution here.
