About
Artificial vanilla-caramel flavour is a blended synthetic flavouring system typically composed of key aroma compounds such as vanillin or ethyl vanillin (vanilla note) and diacetyl, acetoin, or caramelised sugar-derived compounds (caramel note), used to impart a sweet, creamy, toffee-like taste and aroma to food products. It is used across confectionery, dairy, beverages, baked goods, and snack foods to replicate or enhance vanilla and caramel taste profiles at low cost.
Safety summary
The primary components — vanillin, ethyl vanillin, diacetyl, and acetoin — are approved for food use by major regulatory bodies (FDA, EFSA, JECFA) and carry GRAS status when ingested at typical food-use levels. JECFA has set an ADI of 0–3 mg/kg bw/day for ethyl vanillin and 10 mg/kg bw/day for vanillin, both of which are not exceeded under normal dietary conditions. Diacetyl, a common caramel-note compound, is safe for ingestion but poses an inhalation risk (Bronchiolitis obliterans / 'popcorn lung') for occupational workers exposed to high airborne concentrations; this risk is irrelevant to consumers eating the food product.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Permitted as artificial flavourings under FSANZ Food Standards Code Schedule 15; must be used at the lowest functional level necessary.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Vanillin (FL 05.018) and ethyl vanillin authorised without quantitative limits in most food categories under Regulation (EU) No 1334/2008; ADI 10 mg/kg bw for vanillin per JECFA. Diacetyl and acetoin also authorised as flavouring substances without limitations in the EU flavouring register.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Artificial flavouring substances including vanillin and ethyl vanillin are permitted under the FSSAI Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011, subject to Good Manufacturing Practice (GMP) levels. Compounds are listed in the FSSAI Compendium of Flavouring Substances.source |
| FDA (Food and Drug Administration) (United States) | Approved | Vanillin, ethyl vanillin, diacetyl, and acetoin are listed as GRAS synthetic flavouring substances under 21 CFR 182.60; no specific numerical ADI imposed by FDA for food use. Diacetyl is safe for ingestion per FDA but subject to OSHA occupational exposure guidance for inhalation.source |
