What is 2-dodecenal?
2-dodecenal (CAS Number 4826-62-4) is an unsaturated aliphatic aldehyde belonging to the class of organic compounds known as fatty aldehydes. It occurs naturally in various foods including meat, fish, dairy products, and some plants. The compound has a molecular formula of C₁₂H₂₂O and contains a double bond in its carbon chain, which contributes to its distinctive sensory properties.
Common Uses
2-dodecenal is primarily used in the flavor industry as a flavoring agent and adjuvant. It is employed in the formulation of savory flavors intended for processed meat products, cheese preparations, seafood analogs, and savory snack foods. The compound is valued for its ability to enhance and replicate meaty, fatty, and umami-type notes in food systems. It may also be used in very small quantities in other processed food categories where savory flavor profiles are desired.
Safety Assessment
According to FDA records, there are zero reported adverse events associated with 2-dodecenal consumption and zero product recalls linked to this additive. The compound's safety profile reflects its natural occurrence in foods and limited exposure through intentional food use. As a fatty aldehyde, 2-dodecenal is metabolically processed similarly to other naturally occurring aldehydes and lipid-derived compounds found in the diet.
The absence of adverse event reports and recalls indicates no documented safety concerns in the U.S. market. However, comprehensive toxicological studies on this specific compound are limited in the publicly available literature. Standard safety assessments for flavor compounds typically evaluate acute toxicity, mutagenic potential, and metabolic fate.
Regulatory Status
2-dodecenal has not received FDA GRAS (Generally Recognized as Safe) status. This means it does not have an official determination of safety by the FDA under the conditions of its intended use. However, the compound may be used in flavoring formulations under FDA regulations governing flavor ingredients, which allow for use of certain non-GRAS flavoring substances that have not been prohibited.
The lack of GRAS status does not necessarily indicate a safety concern; rather, it reflects that either no formal GRAS petition was submitted, or insufficient data was available for such a determination. Flavoring ingredients are regulated under 21 CFR Part 182 and related sections, which establish safety thresholds based on estimated dietary exposure.
Key Studies
Published scientific literature specifically examining 2-dodecenal is limited. The compound is primarily characterized in flavor chemistry databases and sensory evaluation studies where it is noted as a contributor to the aroma and taste profiles of foods. Its natural presence in meat and dairy products has been documented in volatiles analysis studies.
Because 2-dodecenal is used in small quantities as a flavor component and occurs naturally in foods, traditional acute or chronic toxicity studies may not have been conducted. Safety assessment relies on structural analogy to other fatty aldehydes, metabolic fate predictions, and estimated dietary exposure levels, which are typically very low for flavoring agents.
The flavor industry maintains proprietary databases on the safety and sensory properties of flavor ingredients. Regulatory acceptance is based on the principle that flavoring ingredients are used in very small amounts, and their safety is evaluated under conditions of use.
