| FEMA 3377 Usage And Synthesis |
| Description | 2-trans-6-cis-Nonadienal has an odor reminiscent of green cucumber. The organoleptic character is attributed almost entirely to olfactory sensations. It may be obtained from natural hexenol; from steam distillation of fresh cucumber. | | Chemical Properties | Nona-2-trans-6-cis-dienal has an odor reminiscent of green cucumber. The organoleptic character of this compound is
attributed almost entirely to olfactory sensations. May be obtained from the steam distillation of fresh cucumber. | | Chemical Properties | clear colorless to pale yellow liquid | | Occurrence | Reported as naturally occurring in violet leaves and flowers, in cucumber, sweet and sour cherry, guava, peas,
tomato, potato, bell pepper, wheat bread, rye bread, milk, milk powder, fish and fish oil, roast chicken, guinea hen, beef, beer, coffee,
tea, oats, mango, kelp, prickly pear, malt, dried bonito, endive, oysters, clam and mate. | | Uses | trans-2,cis-6-Nonadienal is an unsaturated aldehyde that is responsible for the cucumber smell of Synura petersenii, a freshwater colonial flagellate. trans-2,cis-6-Nonadienal is also a common natural and drinking water contaminant. | | Preparation | From natural hexenol | | Definition | ChEBI: An enal that is (2E,6Z)-nona-2,6-diene substituted by an oxo group at position 1. | | Aroma threshold values | Detection: 0.01 ppb | | Taste threshold values | Taste characteristics at 10 ppm: green, melon, cucumber-like with an aldehydic nuance | | Synthesis Reference(s) | The Journal of Organic Chemistry, 38, p. 36, 1973 DOI: 10.1021/jo00941a008 | | General Description | Unialgal cultures of various Synurophycean species for the occurrence of trans-2,cis-6-nonadienal have been investigated. | | Safety Profile | Low toxicity by
ingestion and skin contact. A moderate skin
irritant. When heated to decomposition it
emits acrid smoke and irritating fumes. |
