What is Ethyl Acetoacetate Ethyleneglycol Ketal?
Ethyl Acetoacetate Ethyleneglycol Ketal is an organic chemical compound with the CAS number 6413-10-1. It is chemically classified as a ketal, formed from the reaction between ethyl acetoacetate and ethyleneglycol. This synthetic molecule is typically a clear liquid at room temperature and is characterized by its specific aromatic profile, which makes it valuable in the creation of complex food flavors. As a flavoring agent, it is not intended to provide nutritional value but rather to impart or enhance particular taste and aroma characteristics in food and beverages. It is part of a broader category of synthetic flavor chemicals designed to mimic or augment natural flavors, often providing fruity, sweet, or ester-like notes that are difficult to achieve through natural extracts alone.
Common Uses
As a 'FLAVORING AGENT OR ADJUVANT,' Ethyl Acetoacetate Ethyleneglycol Ketal is incorporated into various food products to contribute or modify their sensory profile. Its specific flavor notes are often described as fruity, sweet, or alcoholic, making it suitable for applications where these characteristics are desired. Typical uses include baked goods, confectionery items, desserts, non-alcoholic beverages, and sometimes alcoholic beverages. It is generally used at very low concentrations, consistent with its function as a high-impact flavoring. Adjuvants, in this context, are substances that assist flavorings in their function, often by improving their stability, solubility, or by contributing to a more rounded flavor profile.
Safety Assessment
The safety of Ethyl Acetoacetate Ethyleneglycol Ketal, like other flavoring agents, is assessed based on its chemical structure, metabolic fate, and typical levels of exposure in the diet. In the United States, while it is not formally listed as 'FDA GRAS' (Generally Recognized As Safe) through the FDA's specific GRAS notification pathway, it has been evaluated by the Flavor and Extract Manufacturers Association (FEMA). FEMA has determined Ethyl Acetoacetate Ethyleneglycol Ketal to be GRAS (FEMA No. 3169) for its intended use as a flavoring agent. This independent scientific body's GRAS determinations are widely accepted by the food industry and recognized by the FDA as valid safety conclusions for flavorings. The additive has been associated with 0 reported adverse events and 0 recalls by the FDA, suggesting a lack of widespread consumer safety issues under normal usage conditions.
In the European Union, the European Food Safety Authority (EFSA) has evaluated Ethyl Acetoacetate Ethyleneglycol Ketal as part of a larger group of flavoring substances (Flavouring Group Evaluation 70, FGE.70). In its review, EFSA concluded that there was "no safety concern" for Ethyl Acetoacetate Ethyleneglycol Ketal (FGE.70, no. 136) at the proposed use levels, based on its metabolism and the absence of genotoxic potential. These assessments typically consider the intake levels from all food sources, toxicological data from similar compounds (read-across), and metabolism studies. Flavoring substances are generally used at very low levels in food, which often contributes to their low toxicological concern.
Regulatory Status
**United States:** Ethyl Acetoacetate Ethyleneglycol Ketal is permitted for use as a flavoring agent under its FEMA GRAS status (FEMA No. 3169). The FDA typically accepts FEMA's GRAS determinations for flavorings, allowing their use in food products. This means that while it doesn't have a direct FDA GRAS designation or a specific food additive regulation, its use as a flavoring is deemed safe by an expert panel whose conclusions are generally relied upon by the FDA.
**European Union:** In the EU, Ethyl Acetoacetate Ethyleneglycol Ketal (FL-No: 07.240) is authorized for use as a flavoring substance in various food categories. Its approval is based on the comprehensive safety evaluation conducted by EFSA as part of FGE.70, where it was concluded to pose no safety concern at the typical use levels.
Key Studies
Key safety evaluations for Ethyl Acetoacetate Ethyleneglycol Ketal have been conducted by leading scientific organizations:
* **FEMA GRAS Assessment:** The Flavor and Extract Manufacturers Association (FEMA) Expert Panel reviewed the available scientific data and determined Ethyl Acetoacetate Ethyleneglycol Ketal to be Generally Recognized As Safe (GRAS) for use as a flavoring ingredient (FEMA No. 3169). These assessments consider chemical structure, anticipated dietary exposure, and any available toxicology data for the compound and structurally related substances.
* **EFSA Flavouring Group Evaluation (FGE.70):** The European Food Safety Authority (EFSA) Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food (AFC) evaluated Ethyl Acetoacetate Ethyleneglycol Ketal (as FGE.70, no. 136) within the context of related flavoring substances. Their conclusion, published in reports such as the 'Scientific Opinion on Flavouring Group Evaluation 70, Revision 1 (FGE.70Rev1)' and subsequent updates, indicated no safety concern at the proposed use levels in food, based on a comprehensive analysis of metabolism and toxicology. These evaluations often group substances with similar chemical structures and metabolic pathways, extrapolating data where appropriate to ensure safety across the group.
