Caramel Coating

Caramel coating is a sweet, brown confection made by heating sugars, often with water, butter, or cream. The process of caramelisation changes the sugar's chemical structure, creating its characteristic colour and flavour. It can range from a soft, chewy texture to a hard, brittle one depending on the ingredients and cooking time.

Manufacturers use caramel coating primarily for its sweet flavour and appealing brown colour. It functions as a flavouring agent and a decorative element, adding a rich, sweet taste and visual appeal to a wide range of products. It is commonly found in confectionery, baked goods, ice cream, and dairy desserts.

Caramel colourings are authorised food additives in the UK and are listed on the Register of Food Additive Authorisations. Caramel colour (E150a-d) has been evaluated by EFSA. While generally considered safe at typical consumption levels, some studies have raised questions about certain types of caramel colourings (specifically Class III and IV) and their potential formation of 4-MEI, a substance that the International Agency for Research on Cancer (IARC) has classified as possibly carcinogenic to humans. However, regulatory bodies like EFSA have concluded that current exposure levels to 4-MEI from food are not a concern for human health.
