of fried fats on dilution. It is used to impart a fried, buttery
flavor. It is prepared from Hemiptera insects (trans-form); from
pen-ten-l-en-3-ol converted to the corresponding vinyl ether
which undergoes a Claisen rearrangement to 4-heptenal (transform). | | Chemical Properties | cis-4-Heptenal has an odor reminiscent of heptaldehyde The odor is suggestive of fried fats on dilution It is used to impart a fried, buttery favor. | | Chemical Properties | clear colorless to light yellow liquid | | Chemical Properties | (Z)-4-Heptenal is a widespread volatile trace constituent
