E100–E199 (color additives)

In the European Union, E numbers are used as codes for food color additives. E numbers 100-199 include not only artificial food colors derived from petroleum, but also natural additives originating from sources such as vegetables, insects, or mixtures made from natural foodstuffs. However, although some E number food dyes are not allowed in the EU and US, some are still used illicitly in food products. For a precise quality control of food products, Sigma-Aldrich provides a broad range of neat standards.
