| | α-Methylcinnamaldehyde Usage And Synthesis |
| Description | α-Methylcinnamaldehyde has a characteristic cinnamon-type odor
with a soft, spicy flavor. May be synthesized by condensing benzaldehyde with propionic aldehyde in the presence of a 1% caustic soda
solution; also by the controlled hydrogenation of α-methylcinnamic
aldehyde. | | Chemical Properties | α-Methylcinnamaldehyde has a characteristic cinnamon-type odor and a soft, spicy flavor. | | Chemical Properties | yellow liquid | | Occurrence | Reported found in peppermint oil, sherry and mint | | Uses | alpha-Methyl-trans-cinnamaldehyde is a compound with antifungal activity for proteomics research use. | | Preparation | By condensing benzaldehyde with propionic aldehyde in the presence of a 1% caustic soda solution; also by the controlled
hydrogenation of α-methylcinnamic aldehyde | | Taste threshold values | Taste characteristics at 30 ppm: spice, cinnamon, sweet, woody with a slight pungent and hot bite | | Synthesis Reference(s) | The Journal of Organic Chemistry, 55, p. 2878, 1990 DOI: 10.1021/jo00296a059
