What is Alpha-amylcinnamaldehyde Dimethyl Acetal?
Alpha-amylcinnamaldehyde Dimethyl Acetal (CAS Number 91-87-2) is a synthetic organic compound classified as a flavoring agent. It belongs to the family of acetal compounds, which are formed through chemical reactions between aldehydes and alcohols. This particular compound is a derivative of cinnamaldehyde, the primary component responsible for cinnamon's characteristic flavor and aroma. The dimethyl acetal form represents a chemically modified version designed to provide specific sensory properties in food applications.
Common Uses
This flavoring compound is primarily used in the food industry as a flavor enhancer and flavoring agent adjuvant. It appears in formulations for processed foods, beverages, confectionery products, and baked goods. The compound contributes to complex flavor profiles, particularly those with spice, warm, or aromatic characteristics. Food manufacturers utilize this additive to achieve desired taste profiles while using smaller quantities of traditional spice ingredients. It may also be found in flavoring blends designed for savory products, seasonings, and functional food applications.
Safety Assessment
Alpha-amylcinnamaldehyde Dimethyl Acetal has not been formally granted GRAS (Generally Recognized as Safe) status by the FDA. However, this classification does not indicate the substance is unsafe; rather, it reflects that manufacturers have not pursued formal GRAS notification or that the FDA has not completed such a review. The FDA maintains zero recorded adverse events and zero product recalls associated with this additive, suggesting a favorable safety profile in practical use.
The compound's chemical structure and relationship to naturally-occurring cinnamaldehyde provide some basis for safety consideration. Cinnamaldehyde itself has extensive history of use in food. The acetal modification alters the compound's chemical properties, affecting how it behaves in the body and food matrix. Typical intake levels from flavoring agents are generally recognized as low-exposure substances due to their potent sensory properties and minimal usage quantities.
As with many synthetic flavoring compounds, the absence of adverse events and recalls suggests adequate safety margins in current food applications. However, comprehensive toxicological studies specific to this compound may be limited in public databases.
Regulatory Status
In the United States, this additive is not listed as a GRAS substance on the FDA's official list. This means while it may be used in food, manufacturers should maintain documentation supporting its safety or pursue formal FDA review if desired. The compound appears in the FDA's database of approved flavoring substances but without the expedited GRAS classification.
Regulatory status varies internationally. European food safety authorities have not provided extensive public documentation on this specific compound, though the EU maintains strict flavoring regulations under Regulation (EC) No 1334/2008. Other jurisdictions may have different approval statuses and usage limitations.
Key Studies
Publicly available peer-reviewed research specifically examining alpha-amylcinnamaldehyde dimethyl acetal is limited. Most safety information derives from manufacturer submissions, regulatory databases, and general knowledge of acetal compounds and cinnamaldehyde derivatives.
The chemical class of acetals has been studied for stability, reactivity, and metabolism. Research indicates acetals typically hydrolyze in acidic environments, potentially reverting to parent aldehydes during digestion. The low exposure levels from flavoring applications generally keep systemic doses minimal.
Broader research on synthetic flavoring agents indicates that compounds used in flavoring typically undergo rigorous testing before market approval, though published studies on individual compounds may not always be publicly accessible. The absence of adverse events and recalls over extended market use provides empirical evidence of practical safety.
