| | CIS-4-HEPTENAL Usage And Synthesis |
| Description | cis-4-Heptenal has an odor reminiscent of heptaldehyde. It is suggestive
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
of food flavors. It is a colorless, oily liquidwith a powerful, fatty, somewhat
fishy, and, in high dilution, creamy odor. It can be prepared by several ways, for
example, by starting from (Z)-3-hexenol.
(Z)-4-Heptenal is used in cream, butter, and fat flavors. | | Occurrence | Reported found as a constitutent in butterfat, microbial fermented tea and black Hemiptera bugs | | Uses | cis-4-Heptenal is an unsaturated aldehyde that possesses a fishy aroma. cis-4-Heptenal is a product of oxidative breakdown of fats in fish, and is naturally found in fish oils. | | Preparation | From Hemiptera bugs (trans-form); from penten-1-en-3-ol converted to the corresponding vinyl ether, which undergoes a Claisen rearrangement to 4-heptenal (trans-form). | | Aroma threshold values | Detection: 0.4 ppb. |
