E142 is a food additive approved by the European Union (EU). It is used as a synthetic colouring agent in food and drink products.
The common name for E142 is green S.
E142 is moderately soluble in water, but requires an environment of a neutral pH in order to remain stable.
In a few cases, allergic reactions and anaemia have been reported after contact with high concentrations of this colouring. However, E142 is generally regarded as safe in small quantities.
Examples of food and drink products that sometimes include E142:
- canned peas
- cake mixes
- mint jelly and sauce
