What is Nerolidol?
Nerolidol (CAS Number 7212-44-4) is a sesquiterpene alcohol found naturally in the essential oils of various plants, including nerolidol-containing flowers, woods, and fruits. It is a colorless to pale yellow liquid with a characteristic floral and woody aroma. The compound exists in two isomeric forms and is chemically classified as a C15 alcohol, making it a relatively large organic molecule in the flavoring category.
Common Uses
Nerolidol is primarily used as a flavoring agent and flavoring adjuvant in the food and beverage industry. It appears in formulations for:
- Alcoholic beverages, including spirits and liqueurs
- Non-alcoholic beverages and soft drinks
- Confectionery and candy products
- Baked goods and desserts
- Dairy products
- Savory food products
Its floral, woody, and subtly fruity character makes it valuable for creating complex flavor profiles in both sweet and savory applications. The compound is also used in cosmetics and personal care products due to its aromatic properties.
Safety Assessment
Nerolidol has been used in traditional food applications for decades through its natural occurrence in food flavoring sources. The FDA has received zero adverse events reports associated with nerolidol, and there are no recorded recalls linked to this substance. While nerolidol does not currently hold GRAS (Generally Recognized As Safe) status with the FDA, this does not indicate a safety concern but rather reflects the regulatory classification pathway for this particular ingredient.
The compound has been evaluated in various toxicological studies. In vitro and animal studies have examined its potential effects, with research generally supporting its safety profile at levels used in food flavoring. The European Flavouring Industry has also reviewed nerolidol as part of broader sesquiterpene safety assessments.
As with all flavoring agents, exposure through food is minimal compared to levels tested in safety studies. Nerolidol is volatile and aromatic in nature, with typical use levels in parts per million in finished food products.
Regulatory Status
Nerolidol's regulatory status varies by jurisdiction. In the United States, while it lacks GRAS designation, it may be used in food as a flavoring substance under FDA regulations for flavoring agents not requiring pre-market approval if used at levels consistent with current food industry practice. The European Union includes nerolidol in its flavoring substance registers for use in food.
The lack of GRAS status does not prohibit its use in foods but indicates it follows different regulatory pathways in different regions. Manufacturers using nerolidol should verify compliance with applicable regulations in their target markets.
Key Studies
Research on nerolidol has primarily focused on its occurrence in natural products and its sensory properties. Analytical chemistry studies have identified nerolidol in numerous botanical sources. Toxicological evaluations, including those conducted as part of broader sesquiterpene safety assessments by flavor industry organizations, have examined acute toxicity, genotoxicity, and other endpoints.
No published studies report significant adverse effects from nerolidol at food-relevant exposure levels. The extensive history of use in flavoring applications derived from natural sources contributes to the safety profile.
