About
What it is and where it shows up.
Nature-identical flavouring substances are synthetically produced or chemically isolated compounds that are structurally identical to flavour-contributing molecules found naturally in food or aromatic raw materials. They are added to processed foods to impart, enhance, or modify flavour in a consistent, cost-effective manner.
Safety summary
The regulatory and scientific consensus.
Safety varies significantly by individual substance within this broad class; most are considered safe at typical use levels when assessed through JECFA, EFSA, or FEMA evaluation programmes. Some individual members have demonstrated genotoxic potential and have been restricted or removed from authorised lists. No single ADI applies to the category as a whole; individual substance-level risk assessments govern permitted use levels.
Regulatory landscape
What food-safety regulators have decided.
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | Regulation (EC) No 1334/2008 abolished the standalone 'nature-identical' category; all chemically defined flavouring substances must now be individually evaluated by EFSA and listed on the Union positive list (Annex I), established by Commission Implementing Regulation (EC) No 872/2012. Over 2,000 individual substances have been evaluated. Some genotoxic substances (e.g. pentane-2,4-dione, perilla aldehyde) have been removed. Each substance is approved or restricted case-by-case; no category-level ADI is set.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Formally defined under FSS Regulations 2009, Regulation 1.2.1(29), as substances chemically isolated from aromatic raw materials or obtained synthetically that are chemically identical to substances present in natural products. Permitted under FSS (Food Products Standards and Food Additives) Regulations 2011, Regulation 3.3.1, at GMP levels. Labelling requires declaration of class name of flavour only, not the individual substance name.source |
| FDA (Food and Drug Administration) (United States) | Approved | The US does not formally recognise 'nature-identical' as a regulatory category. Synthetically produced flavour molecules chemically identical to natural ones are classified as 'artificial flavours' under FDA (21 CFR 101.22) or may qualify as GRAS via FEMA expert panel review or FDA GRAS notification process. Synthetic flavouring substances are listed under 21 CFR 172.515. FDA has not challenged FEMA GRAS listings for qualifying flavouring substances.source |
Who should approach with care
Whose guidance would steer them away.
Children — Children represent a sensitive sub-population with higher relative dietary exposure to flavouring substances per body weight; EFSA's exposure assessment models for chemically defined flavourings specifically flag children as a high-exposure group requiring additional safety margin consideration.
Pregnancy — Pregnant women are explicitly identified as a specific sensitive target population in EFSA's food flavouring dietary exposure framework, as certain individual nature-identical substances may carry developmental or reproductive risks not fully characterised at the category level.
Lactation — Lactating women are co-listed with pregnant women as a specific sensitive target population in EFSA's flavouring exposure assessment guidance, given potential transfer of lipophilic flavouring compounds to breast milk.
Other — Individuals with known chemical hypersensitivities, multiple food intolerances, or complex metabolic conditions should consult a doctor, as individual nature-identical flavouring substances have been associated with hypersensitivity reactions in susceptible populations and metabolic clearance varies by substance.
