E128 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 E128 is Red 2G.
E128 gives a red colouration to food products. It is highly soluble in water and tends to be used in meat and confectionary products.
In some cases, E128 has been found to be converted to aniline in the gut.
E128 has been suspected by some of being mutagenic and has been known to cause anaemia due to the production of aniline.
E128 is banned in Australia, as well as many other countries. It is permitted in food products in the UK but even there, use of E128 has been restricted and the ADI (Allowed Daily Intake) has been lowered.
