Group: E100–E199 (colours)
E110 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 names for E110 are sunset yellow FCF and orange yellow S.
E110 is a yellow, synthetic coal tar food colouring that is highly soluble in water. It is a synthetic azo dye and is generally used in fermented foods that require treatment by heat.
E110 is thought by some to worsen asthma and, when taken in combination with benzoates, to induce hyperactivity in some children. Individuals with intolerance to salicylates may also find that they are intolerant to E110, due to the colouring being an azo dye. Some reports have also mentioned nausea, severe weight loss, and vomiting as side-effects of E110.
E110 is banned in Norway.
