Caramelised sugar is used as colouring in cola. Artificial additives do not occur naturally. They are made synthetically for a certain purposes. For example tartrazine is a synthetic colouring added to some sweets to make them yellow. Uses for additives Both natural and artificial additives are used for many different reasons: Preservatives extend the shelf life of a product. Salt is used used in bacon and sausages. Colouring makes food products look more appealing and appetising. Flavourings can be used to add or improve the flavour of a food product. Vanilla flavouring is often added to cakes and biscuits. Emulsifiers are used to prevent ingredients from separating. For example, lecithin, which is found in eggs, is used to stop the ingredients in mayonnaise from separating.
