2-Nonenal Usage And Synthesis
Description2-Nonenal has a very powerful, penetrating fatty odor in concentrated form. It is orris-like, waxy, and quite pleasant on dilution. The odor is reminiscent of dried orange peels. Prepared by oxidation of 9,10,12-trihydroxy stearic acid (Criegee reaction).
Chemical Properties2-Nonenal has a very powerful, penetrating, fatty odor in concentrated form. The odor is orris-like, waxy and quite pleasant on dilution. The odor is also reported as reminiscent of dried orange peels
OccurrenceReported found in orris oil, melon, peach, asparagus, carrot, peas, tomato, wheat and crisp breads, Russian cheeses, caviar, butter, fish oil, cooked beef, mutton, pork, and their fats, hop oil, cognac, roasted filberts and peanuts, soybean, beans, sesame seed, mango, rice, beer, and potato chips
PreparationBy oxidation of 9,10,12-trihydroxystearic acid (Criegee reaction)
DefinitionChEBI: An enal consisting of non-2-ene having an oxo group at the 1-position.
Aroma threshold valuesDetection: 0.1 ppb
Taste threshold valuesTaste characteristics at 10 ppm: green, soapy, cucumber/melon-like with an aldehydic, fatty nuance
Safety ProfileModerately toxic by skin contact. Mddly toxic by ingestion. A severe skin irritant. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
