(+/-)-2,6,10,10-tetramethyl-1-oxaspiro[4,5]deca-2,6-dien-8-one

2,6,10,10-tetramethyl-1-oxaspiro[4,5]deca-2,6-dien-8-one, identified by CAS Number 80722-28-7, is a synthetic organic compound belonging to the class of flavoring agents. The compound features a distinctive spiro ring structure—a bicyclic system where two rings share a single carbon atom—combined with multiple methyl substituents and conjugated double bonds. This structural configuration contributes to its sensory properties and volatile characteristics that make it suitable for flavoring applications.

This flavoring compound is used primarily in the food and beverage industry as a flavoring agent or adjuvant. Its applications typically involve enhancing or modifying the sensory profile of products by contributing specific aromatic notes. Like many synthetic flavor compounds, it is used in very small quantities to achieve desired taste and aroma characteristics. The specific flavor profile associated with this compound makes it suitable for particular food formulations where such sensory properties are desired.

Based on available data, this additive has generated no reported adverse events in the FDA's safety monitoring systems. Additionally, no product recalls linked to this ingredient have been documented, suggesting no safety incidents have triggered regulatory action or public health concerns requiring product removal from the market. The absence of adverse event reports and recalls indicates that this compound has not raised immediate safety flags in post-market surveillance.

However, it is important to note that this compound has not received GRAS (Generally Recognized As Safe) status from the FDA. GRAS determination requires substantial scientific evidence demonstrating safety through either expert consensus or adequate toxicological testing. The lack of GRAS status suggests that either the compound has not undergone the formal review process, limited data is available, or the evidence does not yet meet the threshold for GRAS recognition.

This flavoring agent does not currently hold FDA GRAS designation. In the European Union context, flavoring compounds are typically evaluated by the European Food Safety Authority (EFSA) Panel on Food Flavorings, Nutrients and Food Allergens. The regulatory pathways for flavoring agents can vary by jurisdiction; some compounds may be approved in certain regions but not others, depending on the available safety data and regulatory requirements of each authority.

For food manufacturers seeking to use this ingredient, regulatory compliance depends on the intended market and its specific approval status in that jurisdiction. In the United States, if not GRAS, the compound would require FDA approval as a food additive through the formal petition process before lawful use.

The scientific literature on this specific compound appears limited in publicly available databases. Most information regarding synthetic flavoring compounds derives from structure-activity relationship studies, general toxicological testing of flavoring compounds with similar structural features, and regulatory submissions to food safety authorities. The lack of extensive published independent research may reflect the narrow commercial application of this particular flavoring agent or the proprietary nature of flavor industry data.

Additional research, toxicological assessment, or regulatory submissions may be necessary to establish comprehensive safety data for this compound. Interested parties seeking detailed safety information should contact the FDA or relevant regulatory authorities for available documentation on this specific ingredient.
