What is 2-trans-4-trans-7-cis-decatrienal?
2-trans-4-trans-7-cis-decatrienal (CAS Number: 66642-86-2) is a synthetic organic compound belonging to the class of unsaturated aldehydes. Its chemical structure features a ten-carbon backbone with three double bonds in specific geometric configurations (two trans and one cis arrangement), which contribute to its distinctive flavor profile. This compound is produced through chemical synthesis rather than extracted from natural sources, though it may be designed to approximate flavors found in nature.
Common Uses
As a flavoring agent, 2-trans-4-trans-7-cis-decatrienal is used in the food industry to enhance or create specific aromatic characteristics in processed foods and beverages. Its typical applications include use in flavored beverages, confectionery products, dairy products, and other processed foods where flavor enhancement is desired. The volatile nature of this aldehyde makes it particularly suitable for applications where rapid flavor release and aroma perception are important quality attributes.
The compound is used at levels determined by flavor industry standards to achieve the desired sensory outcome while maintaining product stability and shelf life.
Safety Assessment
According to FDA records, there are zero adverse events associated with 2-trans-4-trans-7-cis-decatrienal and zero product recalls linked to this additive. This lack of reported safety incidents suggests that the compound has not been identified as causing consumer health concerns during its period of use.
However, it is important to note that this additive has not received formal FDA GRAS (Generally Recognized as Safe) status. This designation means the FDA has not made an official determination that the substance is safe for use in food. The absence of GRAS status does not necessarily indicate the substance is unsafe; rather, it indicates that the formal safety review and approval process has not been completed through official FDA channels.
Flavoring compounds used in the United States are often regulated through the Flavor and Extract Manufacturers' Association (FEMA) GRAS program, which provides an alternative pathway for safety assessment. Some flavor ingredients may be considered acceptable for use while not holding direct FDA GRAS status.
As with all synthetic flavor compounds, consumption occurs in very small quantities (typically parts per million in final food products), which significantly limits potential exposure.
Regulatory Status
2-trans-4-trans-7-cis-decatrienal does not currently hold FDA GRAS certification. This means it may be used in foods only if it complies with other applicable food regulations and has undergone appropriate safety assessment through recognized industry bodies like FEMA.
The compound's regulatory status varies internationally. Different countries and regulatory bodies maintain their own lists of approved flavoring agents, and approval in one jurisdiction does not guarantee acceptance elsewhere.
Manufacturers using this ingredient should ensure compliance with all applicable regulations in their target markets and maintain current safety documentation.
Key Studies
Limited published scientific literature specifically addresses 2-trans-4-trans-7-cis-decatrienal in isolation. Most safety assessments of synthetic flavor compounds are conducted through industry-sponsored research submitted to regulatory bodies rather than published in peer-reviewed journals.
Safety evaluations of similar unsaturated aldehyde flavor compounds have generally indicated low toxicity profiles when used at typical food flavoring levels. The volatile and reactive nature of aldehydes means they are typically metabolized rapidly and do not accumulate in body tissues.
The lack of adverse event reports and recalls suggests that any safety concerns, if they exist, have not materialized in real-world food use. However, comprehensive toxicological data on this specific compound may be limited in publicly available sources.
