Colloquial use

In some European countries, the "E number" is used informally as a derogatory term for artificial food additives. For example, in the UK, food companies are required to include the ‘E Number(s)’ in the ingredients that are added as part of the manufacturing process. Many components of naturally occurring healthy foods and vitamins have assigned E numbers (and the number is a synonym for the chemical component), e.g.

Classification by numeric range

NB: Not all examples of a class fall into the given numeric range. Moreover, many chemicals, particularly in the E400–499 range, have a variety of purposes.
