1,1'-(tetrahydro-6a-hydroxy-2,3a,5-trimethylfuro[2,3-d]-1,3-dioxole-2,5-diyl)bis-ethanone

1,1'-(tetrahydro-6a-hydroxy-2,3a,5-trimethylfuro[2,3-d]-1,3-dioxole-2,5-diyl)bis-ethanone, identified by CAS Number 18114-49-3, is a synthetic organic compound belonging to the flavoring agent category. This complex chemical structure contains a fused dioxole ring system with hydroxyl and acetyl functional groups, which contribute to its flavor and aroma properties. The compound is classified as a flavoring agent or adjuvant, meaning it is used to enhance, modify, or complement flavors in food and beverage formulations.

This flavoring compound is utilized in the food industry to provide specific taste and aroma profiles to various products. Like other synthetic flavoring agents, it may be incorporated into beverages, confectionery, baked goods, dairy products, and other processed foods where flavor enhancement is desired. The specific sensory characteristics imparted by this compound determine its particular applications within food manufacturing. Typical usage levels for flavoring agents of this type are generally quite low, often in the parts-per-million range, as these compounds are potent flavor contributors.

As of the available FDA data, there have been zero reported adverse events associated with this additive, and zero recalls have been issued. These metrics indicate no documented safety incidents in the United States food supply related to this compound. However, the absence of reported adverse events does not necessarily indicate comprehensive safety testing or widespread use.

The toxicological profile of this specific compound has not been extensively documented in publicly available scientific literature. Safety assessment of flavoring agents typically involves evaluation of acute toxicity, potential for bioaccumulation, metabolic pathways, and potential allergenicity. The structural features of this compound—including its hydroxyl and acetyl groups—are generally recognized as common functional groups in food-approved flavoring substances, though each unique structure requires individual evaluation.

This additive is not listed on the FDA's GRAS (Generally Recognized As Safe) list, which means it has not received GRAS status through either the FDA's affirmation process or through qualified expert consensus. GRAS status is not a prerequisite for use in food; additives can be approved through other FDA pathways, such as food additive petitions, or may be permitted under existing regulatory frameworks for flavoring agents.

Under FDA regulations, flavoring substances are regulated as food additives and must comply with applicable regulations. The regulatory status of this specific compound in other jurisdictions, such as the European Union or other countries, may differ from United States regulations. Some countries maintain different lists of approved flavoring agents, and approval status varies by region.

Publicly available peer-reviewed studies specifically evaluating 1,1'-(tetrahydro-6a-hydroxy-2,3a,5-trimethylfuro[2,3-d]-1,3-dioxole-2,5-diyl)bis-ethanone appear to be limited. The scientific literature on this particular compound is sparse compared to more widely used flavoring agents. Safety data for this additive, if it exists, may be held as proprietary information by manufacturers or regulatory agencies.

For general information on synthetic flavoring agent safety, regulatory agencies including the FDA and the European Food Safety Authority (EFSA) have established frameworks for evaluating flavor compounds. These evaluations typically consider the compound's chemical structure, proposed use levels, dietary exposure estimates, and toxicological data.
