What is Clove Stem Oil?
Clove stem oil (CAS Number 8015-98-3) is an essential oil extracted from the stems of clove plants belonging to the Eugenia species, primarily Eugenia caryophyllata. The oil is obtained through steam distillation or solvent extraction of plant material. The primary active compound is eugenol, which typically comprises 80-90% of the oil's composition, along with other volatile compounds including caryophyllene and humulene. The oil appears as a pale yellow to colorless liquid with a characteristic warm, spicy aroma.
Common Uses
Clove stem oil is used primarily in the food and beverage industry as a flavoring agent and flavor adjuvant. It is commonly incorporated into:
- Spice blends and seasonings
- Baked goods and confectionery
- Beverages, including alcoholic and non-alcoholic drinks
- Savory food products
- Meat and poultry preparations
- Dental and oral care products
The oil provides flavor characteristics typical of whole cloves but in concentrated form, allowing manufacturers to achieve desired taste profiles with smaller quantities.
Safety Assessment
Clove stem oil has been used in food applications for centuries as part of traditional culinary practices. The FDA database shows zero reported adverse events and zero recalls associated with this additive, indicating a favorable safety record in commercial food use. Eugenol, the primary component, has been evaluated for safety in multiple contexts and is generally recognized as having a long history of safe use in food flavoring applications.
Toxicological studies on eugenol and clove oil derivatives indicate low acute toxicity when used at typical dietary levels. The essential oil is volatile and metabolized relatively rapidly in the body. Contact with the oil in concentrated form may cause skin or mucous membrane irritation, typical of many essential oils, but such exposure is not expected under normal food consumption conditions.
The lack of regulatory approval under FDA GRAS (Generally Recognized as Safe) status does not indicate the substance is unsafe; rather, it reflects that formal GRAS notification has not been submitted or completed for this specific ingredient. Many traditional food flavoring ingredients function without explicit GRAS status while maintaining established safe-use practices.
Regulatory Status
Clove stem oil is not currently listed as GRAS by the FDA, though this does not prohibit its use in foods. The regulatory pathway for essential oils and natural flavoring ingredients varies by jurisdiction and application. In the European Union, similar clove-derived products are permitted under flavoring regulations with established use levels.
Manufacturers using clove stem oil must comply with applicable food safety regulations and labeling requirements in their respective markets. When listed on ingredient labels, it typically appears as "clove oil" or "clove stem oil" among flavoring ingredients.
Key Studies
Research on eugenol and clove oil has examined its antimicrobial, antioxidant, and sensory properties. Studies have confirmed eugenol's chemical composition and its recognized flavoring characteristics. Safety evaluations have demonstrated that typical food-use levels of clove oil present minimal toxicological concern.
The extensive historical use of cloves and clove-derived products in culinary traditions across cultures provides empirical evidence supporting the safety profile of these ingredients when used as flavoring agents at standard levels.
