| | trans,trans-2,4-Decadien-1-al Usage And Synthesis |
| Physical properties | Yellow liquid with a strong smell of chicken and chicken fat. The boiling point is 104°C [933Pa (7mmHg)]. The flash point is above 100°C. The liquid is soluble in ethanol and most non-volatile oils, but it is insoluble in water. It is naturally present in orange peel, bitter orange, lemon, strawberry, and roast chicken, among other natural products. | | Chemical Properties | 2-trans, 4-trans-Decadienal has a powerful, oily, chicken fat odor and a sweet, orange-like odor at high concentration.
It has a grapefruit- or orange-like taste on dilution. | | Occurrence | Reported as occurring in peanut oil and, as a volatile component, in fried potatoes, the trans, trans- form is
reported found among the volatile flavor components of potato chips and tomato. Also found in citrus peel oils, orange juice, tangerine
juice, guava fruit, strawberry fruit, cabbage, carrot, raw potato, bell pepper, butter, cooked chicken, beer, rum, tea, peanut oil,
popcorn, potato chips, corn tortilla, oatmeal, Brazil nut, roasted almonds, roasted peanuts and pecans, soybeans, cassava, caviar,
cooked beef, lamb, mutton, and fish. | | Uses | trans,trans-2,4-Decadienal is an aldehyde with a fat flavor aroma characteristic of chicken but has a citrus odor at lower concentrations. trans,trans-2,4-Decadienal can be found in butter, cooked beef, fish, potato chips, roasted peanut, buckwheat and wheat bread crumb. | | Definition | ChEBI: (2E,4E)-deca-2,4-dienal is a polyunsaturated fatty aldehyde that is decanal which has undergone formal dehydrogenation to introduce trans- double bonds at the 2-3 and 4-5 positions. A product of lipid peroxidation in cell membranes and a component of cooking oil fumes. It has a role as a nematicide and an apoptosis inducer. | | Preparation | By autooxidation of methyl (trans, trans)-linolate hydroperoxide. | | Aroma threshold values | Detection: 0.07 to 10 ppb. Aroma characteristics at 0.1%, rich fatty, aldehydic, green melon, chicken fat,
oily and creamy with chicken stock and chicken meat nuances. | | Taste threshold values | Taste characteristics at 2 ppm: rich oily fatty, aldehydic, green, chicken meat with tropical fruit and cilantro
nuances | | Synthesis Reference(s) | Tetrahedron Letters, 36, p. 4223, 1995 DOI: 10.1016/0040-4039(95)00704-G | | General Description | trans,trans-2,4-Decadienal reacts with cytochrome c to form an adduct. | | Safety Profile | Combustible liquid.
When heated to decomposition it emits
acrid smoke and irritating fumes. |
