What is 11-dodecenoic Acid?
11-dodecenoic acid, identified by CAS number 65423-25-8, is an unsaturated fatty acid containing 12 carbon atoms with a single double bond at the 11th position. It belongs to the family of aliphatic carboxylic acids and is structurally related to naturally occurring fatty acids found in various plant and animal sources. The compound exists as a colorless to pale yellow liquid at room temperature and is used in the food industry primarily as a flavoring agent or flavoring adjuvant.
Common Uses
As a flavoring agent, 11-dodecenoic acid is utilized in food manufacturing to enhance or modify the sensory characteristics of products. Its applications are typically found in processed foods where flavor complexity or enhancement is desired. The compound may contribute subtle flavor notes derived from its fatty acid chemistry. Due to its classification as a flavoring substance, it is used in relatively small quantities to achieve the desired organoleptic effects. Specific food categories using this ingredient vary by manufacturer and regional formulation practices.
Safety Assessment
11-dodecenoic acid has demonstrated a favorable safety profile based on available data. The FDA has recorded zero adverse events associated with this additive, indicating no reported health complaints or safety incidents in the agency's surveillance systems. Additionally, no product recalls involving 11-dodecenoic acid have been documented by the FDA, suggesting consistent safety in commercial applications.
As a fatty acid derivative, the compound would be expected to have low acute toxicity. The gastrointestinal tract can metabolize fatty acids through normal digestive processes. However, comprehensive long-term toxicity or carcinogenicity studies specific to this compound are not prominently documented in public databases, which is not uncommon for minor food ingredients used in very small quantities.
Regulatory Status
11-dodecenoic acid does not currently hold GRAS (Generally Recognized as Safe) status with the FDA. This designation does not necessarily indicate safety concerns; rather, it reflects that a formal GRAS determination has not been submitted or approved through FDA procedures. The absence of GRAS status may indicate limited commercial use or that manufacturers have not pursued this regulatory pathway. The compound may still be permitted in food products under other regulatory frameworks or through different authorization mechanisms depending on jurisdiction and intended use levels.
In the European Union, regulatory oversight of flavoring substances is governed by EFSA (European Food Safety Authority) evaluations. Flavoring substances must comply with EU regulations regarding purity criteria and safety assessments before approval for use.
Key Studies
Publicly available peer-reviewed research specifically targeting 11-dodecenoic acid's safety or toxicology appears limited in the scientific literature. This is typical for minor food additives used at low concentrations. Broader research on medium-chain and long-chain fatty acids demonstrates that these compounds are generally well-tolerated by human metabolism. The chemical structure of 11-dodecenoic acid suggests it would undergo beta-oxidation, the normal metabolic pathway for fatty acid breakdown in the body.
Data on structurally similar fatty acid derivatives, combined with the absence of adverse events in FDA databases, supports the conclusion that this additive has not generated safety concerns in practical food applications. However, manufacturers and regulatory bodies rely on the principle that food ingredients should be used at levels that represent minimal dietary exposure relative to the total diet.
