What is Cinnamon Bark Oil?
Cinnamon Bark Oil is an essential oil extracted from the bark of cinnamon trees, primarily Cinnamomum verum (Ceylon cinnamon) and Cinnamomum cassia (Cassia cinnamon). The oil is obtained through steam distillation or solvent extraction of the dried bark. The primary active compounds include cinnamaldehyde, eugenol, and other volatile aromatic constituents that give cinnamon its distinctive flavor profile. The CAS number 8007-80-5 identifies this specific substance in chemical databases.
Common Uses
Cinnamon Bark Oil is utilized primarily as a flavoring agent in the food industry. Common applications include:
- Baked goods and pastries
- Beverages (hot chocolate, coffee, tea, and flavored drinks)
- Confectionery and candy products
- Dairy products (yogurt, ice cream)
- Breakfast cereals
- Savory sauces and spice blends
- Nutritional supplements and functional foods
The oil is valued for its ability to impart authentic cinnamon flavor at relatively low concentrations, making it cost-effective compared to whole spice.
Safety Assessment
Cinnamon Bark Oil has a well-established history of use in food. The FDA has recorded zero adverse events and zero recalls associated with this additive, indicating a favorable safety profile in commercial food applications.
The safety of cinnamon and its derived products has been extensively studied. The primary component, cinnamaldehyde, comprises 50-90% of cinnamon bark oil depending on the species and extraction method. Cinnamaldehyde has been recognized as Generally Recognized as Safe (GRAS) by the FDA for certain applications.
In typical food flavoring concentrations, cinnamon bark oil is considered safe for consumption. The European Food Safety Authority (EFSA) has evaluated cinnamaldehyde and related cinnamon constituents and concluded they are safe at levels used in food applications. However, it's important to note that isolated cinnamon bark oil at high concentrations differs from the consumption of whole cinnamon spice, which contains lower concentrations of active compounds and additional fiber that affects bioavailability.
Due diligence should be exercised with products containing high concentrations of cinnamon bark oil, particularly for vulnerable populations (pregnant women, individuals with liver disease, those on medications). Coumarin content varies significantly between cinnamon species, with Cassia cinnamon containing higher levels; however, cinnamon bark oil typically contains minimal coumarin due to extraction methods.
Regulatory Status
Cinnamon Bark Oil is not listed as GRAS by the FDA, but this designation does not indicate safety concerns. Rather, GRAS status represents a specific FDA regulatory determination. The substance is permitted for use as a flavoring agent in foods under FDA regulations, and its use is governed by Good Manufacturing Practices (GMP), which stipulate that flavoring agents should be used in the minimum quantities necessary to achieve the desired effect.
In the European Union, cinnamon bark oil derivatives are listed on the Flavoring Register, permitting their use in food applications under established regulations. Various other regulatory bodies worldwide (Health Canada, Food Standards Australia New Zealand, etc.) similarly permit its use as a flavoring ingredient.
Key Studies
Research on cinnamon bark oil constituents, particularly cinnamaldehyde, has demonstrated:
- No significant toxicity in standard toxicological studies at food-relevant doses
- AMES testing showing non-mutagenic properties
- Established acceptable daily intake (ADI) values by international food safety authorities
- Safety data supporting use as a food additive across multiple regulatory reviews
The absence of adverse event reports and recalls in the FDA database, combined with extensive international regulatory acceptance, supports the safety of cinnamon bark oil when used as a flavoring agent in foods at levels consistent with food manufacturing standards.
