What is Angelica Stem Oil?
Angelica stem oil (CAS Number: 977032-48-6) is a volatile essential oil obtained from the stems of Angelica archangelica L., commonly known as garden angelica or archangel. The plant belongs to the Apiaceae family and has been used traditionally in European cuisine and herbal preparations for centuries. The oil is extracted through steam distillation or other mechanical processes and contains naturally occurring volatile compounds that contribute to its characteristic peppery, woody, and slightly bitter aromatic profile.
Unlike angelica root oil, which contains higher concentrations of furocoumarins (phototoxic compounds), angelica stem oil typically contains lower levels of these constituents, making it a potentially safer alternative for culinary applications.
Common Uses
Angelica stem oil is primarily used as a flavoring agent in the food industry. Its applications include:
- Alcoholic beverages, particularly gin, liqueurs, and bitters
- Non-alcoholic beverages and soft drinks
- Flavored confectionery and sweets
- Baked goods and desserts
- Savory products including sauces and condiments
- Herbal and botanical preparations
The oil is typically used in very small concentrations (parts per million range) due to its potent aromatic properties. Flavor scientists appreciate angelica stem oil for its ability to add complexity and depth to flavor formulations without overpowering other ingredients.
Safety Assessment
Angelica stem oil has not been formally reviewed by the FDA as a Generally Recognized As Safe (GRAS) substance, meaning it does not have explicit FDA GRAS status. However, the absence of GRAS status does not indicate the substance is unsafe; rather, it indicates that a formal safety assessment and regulatory petition have not been completed or accepted.
According to FDA records, there are zero reported adverse events associated with angelica stem oil and zero product recalls related to this ingredient. This suggests a lack of documented safety concerns in commercial food use.
The European Food Safety Authority (EFSA) and the International Organization for Standardization (ISO) have evaluated angelica-derived materials. The key safety consideration involves furocoumarins—naturally occurring compounds in the Apiaceae family that can cause photosensitivity reactions (phototoxicity) in some individuals when ingested in high quantities or applied topically before sun exposure. Angelica stem oil contains lower furocoumarin levels compared to angelica root oil, reducing this potential concern.
The European Flavour and Fragrance Association (EFFA) maintains safety data on angelica-derived flavor compounds. At the levels used in food flavoring, angelica stem oil is considered to pose minimal risk to consumers.
Regulatory Status
Angelica stem oil's regulatory status varies internationally:
- **United States**: Not GRAS-designated; may be used under the FDA's Food Additives Amendment or as a natural flavoring if meeting specific criteria
- **European Union**: Listed in the EU Register of Flavoring Agents; evaluated under existing regulatory frameworks for botanical flavoring substances
- **Japan, Canada, and Australia**: Permitted in food applications within established guidelines for natural flavor ingredients
Manufacturers using angelica stem oil in products for sale in the United States typically rely on its history of use in food or petition for GRAS status if regulatory certainty is desired.
Key Studies
Scientific literature on angelica stem oil is limited compared to other common flavor ingredients. Available research includes:
- Chemical composition analyses confirming lower furocoumarin content in stem oil versus root oil
- Phytochemical studies identifying compounds such as alpha-pinene, myrcene, and limonene as major volatile constituents
- Safety evaluations by flavor industry associations confirming acceptable use levels in food applications
The absence of published adverse event data and the ingredient's long history of culinary use in European food traditions support its general safety profile at typical food flavoring concentrations.
