Caustic sulphite caramel

Caustic sulphite caramel, also known as E150b, is a type of caramel colour. It is produced by the controlled heating of carbohydrates (such as sugars) in the presence of sulphites and ammonia compounds, resulting in a dark brown colour. The process involves specific conditions to achieve the desired colour intensity and shade.

This additive is primarily used to impart a brown colour to a wide range of food and beverage products. Its deep brown hue makes it suitable for items like ice creams, dairy mousses, sweetened beverages, confectionery, and baked goods. Manufacturers use it to achieve a consistent and appealing colour, enhancing the visual presentation of their products.

Caustic sulphite caramel (E150b) is an authorised food additive in Great Britain, listed on the Register of Food Additive Authorisations. European food safety authorities, including EFSA, have evaluated caramel colours. JECFA has also evaluated caramel colours and established an acceptable daily intake (ADI) for certain types, though specific numeric limits are not stated here. At typical consumption levels found in foods, it is generally considered safe. Some studies have investigated potential health effects, but the evidence is not conclusive, and regulatory bodies continue to monitor safety.
