About
Artificial caramel flavour is a synthetic formulation of chemical compounds—including diacetyl (butane-2,3-dione), furaneol (DMHF), maltol, and related Maillard-reaction analogues—engineered to mimic the sweet, buttery, toasty aroma and taste of caramelised sugar. It is used at trace levels in confectionery, beverages, baked goods, dairy products, and snack foods to deliver consistent caramel character without the variability of natural caramelisation.
Safety summary
At typical dietary intake levels, the constituent compounds of artificial caramel flavour are considered safe by the FDA under 21 CFR 172.515 and evaluated as GRAS by the FEMA Expert Panel. However, diacetyl—a prominent component—is well-documented to cause obliterative bronchiolitis ('popcorn lung') in food-manufacturing workers exposed to high inhalation concentrations, raising scrutiny even at lower consumer-level exposures from heated products. No ADI has been established for the mixture as a whole; the chemically distinct caramel colour additives (E150a–d) carry an EFSA group ADI of 300 mg/kg bw/day, and EFSA noted high-consuming children and adults may approach or exceed individual class ADIs.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Permitted as a flavouring substance under FSANZ Food Standards Code Standard 1.3.1. Flavouring substances must meet JECFA or FEMA GRAS criteria; no specific ADI established for the mixture.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Regulated as a food flavouring under Regulation (EC) No 1334/2008. Individual caramel-type flavouring substances are evaluated under EFSA's Flavouring Group Evaluation programme. No E number is assigned to artificial caramel flavour as a formulated mixture; individual components may be listed in the Union list of flavouring substances.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Permitted as an artificial flavouring substance under FSS (Food Products Standards and Food Additives) Regulations, 2011, Regulation 3.3.1(1). FSSAI defines artificial flavouring substances as those not identified in natural products intended for human consumption. Mandatory labelling as 'artificial' required under FSS (Labelling and Display) Regulations, 2020; the common name of the flavour (e.g., 'caramel') must be declared on the label.source |
| FDA (Food and Drug Administration) (United States) | Approved | Regulated as synthetic flavoring substances and adjuvants under 21 CFR 172.515. Key component compounds—diacetyl (FEMA 2370), furaneol (FEMA 3174), maltol (FEMA 2656), ethyl maltol (FEMA 3487)—hold individual GRAS status via the independent FEMA Expert Panel. Used at GMP levels; no compound-specific ADI established for the mixture. |
