What is Citronellyl Anthranilate?
Citronellyl Anthranilate (CAS 68555-57-7) is a synthetic organic compound categorized as an ester. Chemically, it is formed from citronellol, a common fragrance and flavor component found in various essential oils, and anthranilic acid, an aromatic amino acid. This combination yields a substance with a distinctive and appealing sensory profile. It is primarily known for its aromatic qualities, which are often described as floral, fruity, grape-like, or reminiscent of orange blossom. In the context of food additives, Citronellyl Anthranilate serves solely as a flavoring agent, contributing specific desirable taste and aroma characteristics to food and beverage formulations.
Common Uses
The primary application of Citronellyl Anthranilate is in the food and beverage industry, where it is incorporated as a flavoring agent or adjuvant. Its unique floral-fruity, grape, or orange blossom notes make it a valuable ingredient for creating complex flavor profiles. It can be found in a variety of products, including soft drinks, confectionery, baked goods, dairy products, and certain alcoholic beverages, where it helps to enhance or round out the overall taste experience. Beyond food, Citronellyl Anthranilate also finds use in the fragrance industry, where its appealing aroma makes it suitable for perfumes, cosmetics, and personal care products.
Safety Assessment
The safety of Citronellyl Anthranilate as a food additive has been subject to evaluation by independent scientific expert panels, although it does not hold an explicit Generally Recognized As Safe (GRAS) listing by the U.S. Food and Drug Administration (FDA). In the United States, the Flavor and Extract Manufacturers Association (FEMA) Expert Panel has evaluated Citronellyl Anthranilate (FEMA GRAS No. 3346) and determined it to be GRAS for its intended uses as a flavoring substance. FEMA's GRAS determinations are based on a thorough review of toxicological data, exposure estimates, and expert judgment, and are widely accepted by the FDA for flavorings.
In the European Union, the European Food Safety Authority (EFSA) has also assessed Citronellyl Anthranilate as part of its comprehensive Flavouring Group Evaluations (FGE). It is included in FGE.09 Revision 1, subgroup 4.1 (Anthranilates), and is identified with FL number 04.030. EFSA's Scientific Panel on Food Additives and Flavourings concluded that there are no safety concerns for Citronellyl Anthranilate and other related anthranilate flavouring substances at their current estimated levels of intake, provided specific purity criteria are met. These evaluations consider various toxicological endpoints, including genotoxicity, subchronic toxicity, and often leverage data from structurally related compounds (read-across principle) to establish safety profiles.
Regarding post-market surveillance, the FDA's adverse event reporting system shows 0 adverse events specifically linked to Citronellyl Anthranilate. Similarly, there are 0 recalls associated with this additive. While the absence of reported adverse events or recalls is generally a positive indicator, it is important to note that these systems primarily capture significant or widespread issues, and less common or minor sensitivities may not always be reported or directly attributed to specific minor flavoring agents.
Regulatory Status
In the United States, Citronellyl Anthranilate is permitted for use as a flavoring agent based on the independent GRAS determination by the FEMA Expert Panel (FEMA GRAS No. 3346). While the FDA has not issued an explicit GRAS regulation for this specific compound, the agency generally accepts FEMA's expert conclusions for flavorings, allowing their use in food products when properly manufactured and used according to GRAS conditions.
In the European Union, Citronellyl Anthranilate (FL No. 04.030) is approved for use as a flavoring substance under Regulation (EC) No 1334/2008. Its inclusion in the Union list of authorized flavorings is based on a positive safety assessment by EFSA, as detailed in their Flavouring Group Evaluation reports. This regulatory framework ensures that flavoring agents permitted in the EU have undergone scientific scrutiny to confirm their safety at anticipated consumption levels.
Globally, many other countries and regions often refer to the safety assessments conducted by expert bodies like FEMA and EFSA, or adopt similar international guidelines, when determining the permissibility of flavorings like Citronellyl Anthranilate in their food supplies.
Key Studies
The primary 'key studies' for Citronellyl Anthranilate are the comprehensive scientific evaluations conducted by leading expert panels in food safety and flavor chemistry. These include:
* **FEMA GRAS Monographs and Publications:** The Flavor and Extract Manufacturers Association (FEMA) Expert Panel's determination of Citronellyl Anthranilate as GRAS (FEMA GRAS No. 3346) is a foundational safety assessment in the U.S. These evaluations involve extensive literature reviews, analysis of toxicology studies (including genotoxicity, acute and subchronic toxicity, metabolism, and often read-across data from structurally related compounds), and exposure assessments to determine safety at typical use levels.
* **EFSA Flavouring Group Evaluations (FGEs):** The European Food Safety Authority (EFSA) has evaluated Citronellyl Anthranilate within the framework of its Flavouring Group Evaluation FGE.09 Revision 1 (FL No. 04.030). These scientific opinions systematically assess the safety of groups of chemically related flavoring substances. EFSA's reviews synthesize available toxicological data, considering absorption, distribution, metabolism, excretion, and potential for adverse effects, to conclude on safety under specified conditions of use. Their conclusions are published as scientific opinions and form the basis for regulatory decisions in the EU.
These evaluations, rather than single experimental studies, represent thorough scientific consensus reviews of the available data to establish the safety profile of the additive for its intended uses.
