What is Cis-3-hexenyl Hexanoate?
Cis-3-hexenyl hexanoate (CAS Number 31501-11-8) is a synthetic organic compound classified as an ester, consisting of hexanoic acid combined with cis-3-hexenol. This flavoring agent is designed to replicate fresh, fruity, and herbaceous sensory notes commonly associated with fruits, vegetables, and plants. The compound belongs to the broader category of synthetic flavoring substances used in the food industry.
Common Uses
Cis-3-hexenyl hexanoate is used as a flavoring agent in various processed food and beverage applications. Its primary function is to provide or enhance fruity and fresh flavor notes in products such as:
- Beverages (juices, soft drinks, flavored waters)
- Confectionery and candy
- Baked goods
- Dairy products
- Flavored yogurts and desserts
- Savory snacks
The compound is typically used in very small concentrations, as is standard practice with synthetic flavor compounds, to achieve the desired sensory effect without significantly altering the product's nutritional profile or safety profile.
Safety Assessment
Cis-3-hexenyl hexanoate has not been evaluated for GRAS (Generally Recognized as Safe) status by the FDA. However, the absence of GRAS status does not indicate the compound is unsafe; rather, it means formal FDA evaluation through the GRAS notification process has not been completed or pursued.
According to FDA records available through their Adverse Event Reporting System (FAERS), there have been zero reported adverse events associated with this additive. Additionally, there are no FDA-recorded recalls linked to cis-3-hexenyl hexanoate. These indicators suggest no documented safety concerns in the U.S. food supply.
The compound's ester structure is consistent with many naturally occurring and synthetic flavoring compounds that are widely recognized as safe. Esters of this type are metabolized similarly to other dietary esters and fats, breaking down into their component parts during digestion.
Regulatory Status
The regulatory status of cis-3-hexenyl hexanoate varies by region. In the European Union, it may be listed on approved flavor ingredient registries, though specific classification and approval status should be verified through EFSA (European Food Safety Authority) databases for the most current information.
In the United States, while not GRAS-affirmed, the compound may be used in foods under other regulatory pathways. Manufacturers employing this ingredient should verify compliance with current FDA regulations and maintain appropriate documentation for food safety audits.
The lack of GRAS designation does not prohibit the use of this ingredient in foods; rather, it indicates that the specific GRAS notification pathway has not been formally completed with the FDA.
Key Studies
Limited published scientific literature is available specifically examining cis-3-hexenyl hexanoate in isolation. Like most synthetic flavor compounds, safety evaluation typically relies on:
1. Structural analysis and comparison to known safe compounds
2. Metabolic pathway assessment based on ester chemistry
3. Toxicological data from similar compounds in the same chemical family
4. Historical use data and adverse event monitoring
The absence of reported adverse events and recalls in FDA databases, combined with zero documented consumer complaints, suggests this flavoring agent has not raised safety concerns in practical food applications.
