What is Allyl Valerate?
Allyl valerate (CAS Number: 6321-45-5) is an ester compound formed from allyl alcohol and valeric acid. It belongs to the class of organic compounds commonly used in the flavor and fragrance industry. The compound has a molecular structure that contributes fruity, apple-like, and herbal organoleptic properties, making it valuable in food flavoring applications.
Common Uses
Allyl valerate is employed as a flavoring agent or flavor adjuvant in various food and beverage products. Its primary applications include:
- Processed and packaged foods requiring fruity flavor notes
- Beverage flavoring formulations, particularly fruit-flavored drinks
- Confectionery and candy products
- Dairy-based products and yogurts
- Baked goods and grain-based foods
- Flavor compound blends used by food manufacturers
The compound is typically used in very small quantities, as is standard practice with most synthetic flavor compounds, where efficacy is achieved at concentrations measured in parts per million.
Safety Assessment
Allyl valerate has not been formally listed by the FDA as a Generally Recognized As Safe (GRAS) substance. However, this designation does not automatically indicate a safety concern; rather, it reflects that formal GRAS notification or approval has not been pursued or completed through FDA channels.
According to FDA records, there have been zero adverse events reported and zero recalls associated with allyl valerate. This absence of documented adverse outcomes suggests no significant safety issues have been identified during its use in food applications.
As a naturally-occurring type flavor compound with a structural class similar to other approved esters, allyl valerate exhibits chemical characteristics consistent with flavoring agents generally recognized as safe when used appropriately. The ester functional group is common among approved food flavorings, and valeric acid derivatives have long histories of use in food and fragrance applications.
Regulatory Status
Allyl valerate's regulatory status varies internationally. In the European Union, ester-type flavor compounds are subject to evaluation by the European Food Safety Authority (EFSA) under Regulation (EC) No 1334/2008. The compound may be listed in flavor substance inventories depending on its approval status in specific jurisdictions.
In the United States, while not designated as GRAS by FDA action, allyl valerate may be used under FDA regulations for flavoring purposes if manufacturers maintain appropriate safety substantiation and comply with labeling requirements. Flavoring compounds not explicitly prohibited may be used provided they meet safety standards and do not exceed amounts necessary to achieve intended flavoring effects.
Manufacturers using allyl valerate are responsible for ensuring its safety through appropriate toxicological data and documentation, consistent with FDA expectations for flavoring substances.
Key Studies
Limited published scientific literature specifically addresses allyl valerate's safety profile in isolation. Safety assessment of ester-type flavorings generally relies on:
- Chemical structure-activity relationship (SAR) analyses comparing allyl valerate to structurally similar approved flavor compounds
- Historical use data in food applications
- General toxicological information regarding valeric acid and allyl alcohol metabolism
- Acute toxicity studies typical for ester flavorings
The absence of adverse events or recalls in FDA databases, combined with the compound's similarity to other established food-grade esters, suggests acceptable safety margins when used as intended in flavoring applications at typical use levels. Further formal toxicological studies would provide additional safety confirmation, though standard flavor compound safety assessments typically utilize dose-dependent principles where minimal exposure levels in food applications present negligible risk.
