What is 2-trans,6-cis-dodecadienal?
2-trans,6-cis-dodecadienal is a synthetic flavoring compound with the CAS number 21662-13-5. It is an unsaturated aldehyde consisting of a 12-carbon chain with double bonds in the trans configuration at position 2 and cis configuration at position 6. This structural configuration gives the molecule distinct organoleptic properties that make it useful in food flavoring applications.
As a synthetic compound, 2-trans,6-cis-dodecadienal is manufactured through chemical synthesis rather than extracted from natural sources, though similar compounds may occur in trace amounts in various plant materials.
Common Uses
2-trans,6-cis-dodecadienal is used as a flavoring agent and flavor enhancer in the food industry. Its primary applications include:
- Beverages, including both alcoholic and non-alcoholic drinks
- Confectionery and candy products
- Dairy products and dairy alternatives
- Baked goods and grain-based products
- Savory snacks and processed foods
- Condiments and sauces
The compound is valued for its ability to contribute specific flavor characteristics and enhance existing flavor profiles in formulations. Like many synthetic flavoring compounds, it is typically used in very small concentrations to achieve the desired sensory effect.
Safety Assessment
According to FDA records, there have been zero adverse events and zero recalls associated with 2-trans,6-cis-dodecadienal. This lack of reported safety incidents suggests no acute toxicity concerns have emerged from consumer use.
The compound is not currently listed on the FDA's Generally Recognized As Safe (GRAS) list, which means it has not undergone the formal GRAS notification process. However, the absence of GRAS status does not necessarily indicate a safety concern; rather, it reflects that the manufacturer may not have submitted a GRAS affirmation petition or that such a petition may not have been completed.
As with many synthetic flavor compounds, toxicological data on 2-trans,6-cis-dodecadienal exists in scientific literature. The compound has been studied for potential systemic effects, and these studies have generally not identified significant safety concerns at the levels used in food applications. The use of such compounds is typically restricted to very low concentration ranges, which further minimizes potential exposure.
Regulatory Status
The regulatory status of 2-trans,6-cis-dodecadienal varies by jurisdiction:
- **United States**: The compound is not on the FDA's GRAS list but may be used in foods under the Food Additive Petition process if approved, or under existing regulations for flavoring substances.
- **European Union**: Flavoring regulations in the EU are complex, with different approval statuses for various flavoring compounds. 2-trans,6-cis-dodecadienal may be permitted under EU Regulation (EC) No 1334/2008 depending on its classification and intended use.
- **Other Regions**: Approval status varies in other countries and regions, and manufacturers must comply with local regulations before marketing products containing this ingredient.
Manufacturers using this flavoring compound must ensure compliance with all applicable regulations in their target markets.
Key Studies
Scientific literature on 2-trans,6-cis-dodecadienal is limited compared to more widely used flavoring compounds. Available research has focused on:
- Synthesis and chemical characterization of the compound
- Flavor contribution and sensory properties in food applications
- Basic toxicological screening studies
The compound has not been the subject of large-scale epidemiological studies, as is typical for flavoring agents used in small quantities. Safety assessments have generally relied on structure-activity relationship analyses and in vitro or animal model studies.
Additional research or safety evaluations may be undertaken by manufacturers or regulatory bodies if needed for specific market authorizations.
