About
What it is and where it shows up.
Sunset Yellow FCF is a synthetic azo dye that imparts an orange-yellow colour to food and beverages. It is widely used in soft drinks, confectionery, desserts, custard powders, marmalade, and bakery products to enhance or restore visual appeal.
Safety summary
The regulatory and scientific consensus.
EFSA and JECFA both established an ADI of 4 mg/kg body weight/day (revised upward from a temporary 1 mg/kg bw/day in 2014), with exposure estimates for all population groups considered well below this threshold. The dye can trigger histamine release, potentially causing allergic reactions and worsening asthma symptoms in sensitive individuals. In the EU and UK, foods containing E110 must carry a mandatory warning stating 'may have an adverse effect on activity and attention in children'; high-percentile intake in children aged 1–10 years was previously found to approach or slightly exceed the earlier temporary ADI.
Regulatory landscape
What food-safety regulators have decided.
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Restricted | Authorised as a food colour under Commission Regulation (EC) No 1333/2008 (Annex II and III). ADI of 4 mg/kg bw/day established by EFSA ANS Panel in 2014 based on a NOAEL of 375 mg/kg bw/day from long-term rat studies and an uncertainty factor of 100. Mandatory warning label 'may have an adverse effect on activity and attention in children' required on all products containing E110 per Annex V of Regulation (EC) No 1333/2008.source |
| Food Standards Agency (FSA) / Food Standards Scotland (FSS) (United Kingdom) | Restricted | Permitted but requires mandatory warning 'May have an adverse effect on activity and attention in children' on all products containing E110. The FSA actively encourages manufacturers to seek natural alternatives and some retailers have already removed it voluntarily.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Permitted synthetic food colour listed under FSS (Food Products Standards and Food Additives) Regulations 2011, Chapter 3 (Substances Added to Food). Permitted in specific food categories including powdered soft drink concentrates, confectionery, and bakery products at defined maximum levels. Specifications cover purity, heavy metal limits (lead, arsenic, zinc), and dye intermediates.source |
| FDA (Food and Drug Administration) (United States) | Approved |
Who should approach with care
Whose guidance would steer them away.
Children — EU and UK regulations mandate a warning that E110 'may have an adverse effect on activity and attention in children'; high-percentile exposure in children aged 1–10 years was previously found to approach or slightly exceed the former temporary ADI of 1 mg/kg bw/day.
Infants — No safe use level has been established for infants; the hyperactivity and histamine-release concerns, combined with the absence of infant-specific exposure data, make avoidance prudent.
Other — Individuals with asthma, urticaria, or known azo-dye sensitivity should exercise caution, as Sunset Yellow FCF can trigger histamine release and worsen allergic and respiratory symptoms.
Epilepsy — Some azo dyes including Sunset Yellow FCF have been associated with neurobehavioural effects in animal studies; individuals with neurological conditions such as epilepsy should consult a doctor before regular consumption.
Ibs — Animal studies have shown histopathological alterations in the intestine following Sunset Yellow FCF exposure, suggesting potential irritation of the gastrointestinal tract relevant to those with IBS.
