What is Methyl Trans-2-octenoate?
Methyl Trans-2-octenoate (CAS Number 7367-81-9) is an ester compound belonging to the class of organic chemicals used in food flavoring. The compound consists of a methyl ester derived from trans-2-octenoic acid. It is a clear liquid with characteristic fruity and green vegetable odor notes, making it valuable in the flavor industry for creating complex taste and aroma profiles in food and beverage products.
Common Uses
Methyl Trans-2-octenoate is employed as a flavoring agent in various food applications. It is typically used in small quantities to provide fruity notes reminiscent of apples, melons, and other fresh produce. The compound may be found in beverages, confectionery products, baked goods, dairy products, and savory food items where enhanced flavor complexity is desired. As a flavoring adjuvant, it works synergistically with other flavor compounds to create balanced sensory experiences.
The compound is generally used at levels well below 1% by weight in final food products, as flavoring agents are potent and require minimal quantities to achieve desired effects.
Safety Assessment
Methyl Trans-2-octenoate has not generated any reported adverse events in FDA databases and has not been associated with any food recalls. The absence of adverse event reports suggests that the compound has not caused documented health concerns at levels of use in food applications.
The compound's safety profile is supported by its structural similarity to naturally occurring esters found in fruits and vegetables. Many flavor compounds in this chemical class have established safety precedents. However, comprehensive toxicological studies specific to this particular compound are limited in publicly available scientific literature.
As with all food additives, safety depends on appropriate use levels. Flavoring agents are specifically designed for use at very low concentrations, which further supports their safety margins. The flavor industry operates under strict quality and purity standards to ensure product consistency.
Regulatory Status
Methyl Trans-2-octenoate is not listed on the FDA's GRAS (Generally Recognized As Safe) inventory. This does not indicate the substance is unsafe; rather, it means the compound has not undergone the formal GRAS notification process or does not have a long history of common use in foods that would support GRAS status.
In the European Union, flavoring substances are regulated under the Flavourings Regulation (EC) No 1334/2008. The regulatory approach in the EU focuses on safety assessment through established toxicological evaluation procedures. Use in food applications requires compliance with maximum use levels and purity specifications established by regulatory authorities.
Manufacturers using this flavoring compound must ensure compliance with all applicable regulations in their respective markets, including proper labeling and documentation of use levels.
Key Studies
Scientific literature on Methyl Trans-2-octenoate is limited compared to more widely used flavor compounds. Available chemical and sensory data indicate the compound functions effectively as a flavor ingredient at typical use levels. The structural class of methyl esters derived from unsaturated fatty acids has been studied in food safety contexts, with research generally supporting their safety when used as intended.
Research on related ester compounds has demonstrated rapid metabolism and clearance when ingested at food-relevant concentrations. The absence of reported adverse events and recalls provides real-world evidence supporting safe historical use.
Further toxicological characterization would provide additional safety data, though the current safety record remains consistent with compounds of similar chemical structure used in the flavor industry.
