Food additives don’t have nutritional value, but they are added to food in small amounts to serve a specific function. Some, like preservatives, stop bacteria or mould from spoiling your food, so that it lasts longer. Colourings are used to make our food looks more appealing. Emulsifiers allow water and oils to remain mixed together in an emulsion, like in mayonnaise for example. Even though they might have a negative perception, every additive that we find on our plate has been thoroughly tested and approved by the European Food Safety Authority (EFSA) and classified as safe.
