What is Hept-trans-2-en-1-yl Acetate?
Hept-trans-2-en-1-yl acetate (CAS Number: 16939-73-4) is a synthetic organic compound belonging to the class of acetate esters. It is characterized by a seven-carbon chain with a trans double bond at the second position, acetylated at the terminal hydroxyl group. This chemical structure contributes to its sensory properties, primarily delivering fruity and floral flavor notes reminiscent of tropical and stone fruits.
Common Uses
This flavoring compound is used in the food and beverage industry as a flavoring agent or flavor adjuvant. Its primary applications include:
- Fruit-flavored beverages and drinks
- Confectionery and candy products
- Dairy products including yogurts and flavored milk
- Baked goods and desserts
- Processed snack foods
The compound is typically used in very small concentrations, as is standard practice with synthetic flavor compounds, to achieve desired sensory profiles without contributing significantly to the overall composition of the final food product.
Safety Assessment
As of the available data, there have been zero adverse events reported to the FDA associated with hept-trans-2-en-1-yl acetate, and no food recalls have been linked to this compound. This suggests a favorable safety profile in practical food applications where it is currently used.
It is important to note that this compound does not hold FDA GRAS (Generally Recognized As Safe) status. GRAS status is a formal designation that requires either a history of safe use or substantial scientific evidence demonstrating safety. The absence of GRAS status does not necessarily indicate a safety concern; rather, it reflects that the compound has not undergone the formal GRAS notification process with the FDA or that such a notification has not been accepted.
The compound appears to be used in jurisdictions that permit its use under different regulatory frameworks, where it may be approved through alternative safety assessment pathways. In the European Union, similar acetate ester flavorings are evaluated by the EFSA (European Food Safety Authority) through their flavoring approval processes.
Regulatory Status
In the United States, hept-trans-2-en-1-yl acetate is not listed on the FDA's GRAS inventory. However, its absence from this list does not prohibit its use in food; rather, it means companies using this ingredient would need to comply with applicable regulatory requirements, which may vary by jurisdiction and food category.
International regulatory status may vary. Some countries regulate synthetic flavoring compounds through positive lists of approved substances, while others use alternative approval mechanisms. The compound's regulatory status should be verified for specific jurisdictions and food applications.
Key Studies
Scientific literature on this specific compound is limited in the public domain. Toxicological assessment of acetate ester flavorings generally indicates low toxicity when used at typical flavor levels. As with most flavor compounds, safety is primarily ensured through:
- Use at very low concentration levels (parts per million)
- The body's natural ability to metabolize acetate esters
- Structural similarity to naturally occurring compounds
Manufacturers using this ingredient typically rely on proprietary safety data or assessments conducted under regulatory frameworks in their operating jurisdictions. The absence of reported adverse events and recalls suggests adequate safety margins in current use patterns.
