Chemical Properties
Cinnamaldehyde ethylene glycol acetal has a soft, warm, spicy odor reminiscent of cinnamon; sweet, spicy cinnamon–
allspice flavor.
Uses
This acetal is used in flavor compositions such as Allspice, Cassia, Cinnamon, Clove and various Spice blends, etc. Concentration is usually very small (a few ppm. ) in the finished product. Under distinctly acid conditions (pickles, etc. ), the acetal will decompose and act as Cinnamic aldehyde. This will change the flavor effect of the composition. However, this acetal is moderately stable under mildly acid conditions.
Preparation
From cinnamic aldehyde and ethylene glycol.
