What is Isocyclocitral?
Isocyclocitral (CAS Number: 1335-66-6) is a synthetic organic compound belonging to the class of flavoring agents. It is a cyclic terpene-derived molecule that exhibits fruity and citrus aromatic properties. As a synthetic flavoring substance, isocyclocitral is produced through chemical synthesis rather than isolated from natural sources, though it may also occur naturally in trace amounts in certain fruits and plants.
Common Uses
Isocyclocitral is employed in the food and beverage industry as a flavoring agent or adjuvant. Its primary applications include:
- Flavoring for beverages (juices, soft drinks, alcoholic drinks)
- Flavoring for confectionery and candy products
- Enhancement of fruity and citrus notes in processed foods
- Use in flavor blends and compositions for various food applications
As a flavoring adjuvant, isocyclocitral typically appears in very small concentrations within food products, functioning to enhance or modify the sensory profile of foods without serving a preservative, coloring, or nutritional role.
Safety Assessment
Isocyclocitral has not been evaluated by the FDA under the Generally Recognized as Safe (GRAS) program, meaning it does not have formal GRAS status in the United States. However, the absence of GRAS status does not necessarily indicate safety concerns; rather, it reflects the specific regulatory pathway and evaluation history for this particular substance.
According to FDA records, there are zero reported adverse events associated with isocyclocitral and zero product recalls attributable to this ingredient. This absence of reported safety incidents suggests a favorable safety profile in practical food use.
The European Food Safety Authority (EFSA) has evaluated various flavoring compounds under Regulation (EC) No. 1334/2008, which establishes criteria for flavoring substances in the European Union. Isocyclocitral's evaluation status and any EFSA conclusions regarding this specific flavoring agent should be consulted for comprehensive international safety information.
Toxicological data on isocyclocitral, as with many synthetic flavoring compounds, is typically generated through standard safety testing protocols including acute toxicity studies, and the compound is generally expected to have low toxicity given its functional classification and typical use levels in food applications.
Regulatory Status
In the United States, isocyclocitral is not on the FDA's GRAS list, which means it is not formally affirmed as safe for use in food. However, food manufacturers may petition the FDA for GRAS status or may use the substance under FDA Food Additive Petition approval. Alternatively, some flavoring compounds operate under pre-1958 grandfather provisions or FDA compliance policy guidance for flavoring ingredients.
In the European Union, flavoring substances must comply with Regulation (EC) No. 1334/2008 and appear on the EU's positive list of flavorings authorized for use in food.
The regulatory status of isocyclocitral should be verified with current FDA and relevant international regulatory authorities before commercial food use, as regulations are subject to periodic review and updates.
Key Studies
Limited published scientific literature specifically addresses isocyclocitral safety. As a synthetic flavoring agent used in minute quantities, isocyclocitral follows the same general safety assessment framework as other flavoring compounds. The International Organization of the Flavor Industry (IOFI) and the Flavor and Extract Manufacturers Association (FEMA) maintain databases of flavor ingredient safety evaluations.
The absence of reported adverse events and recalls in FDA records over decades of food industry use suggests that isocyclocitral has demonstrated practical safety in food applications at typical use levels. However, comprehensive toxicological dossiers and published peer-reviewed safety studies specific to this compound are limited in public scientific literature.
