Properties and functions of trans-2,4-Decadienal
At room temperature, it is a yellow liquid with strong chicken, chicken oil, and citrus aromas.
Boiling point 104 ºC (933 Pa), flash point above 100 ºC, density 0.872 g/mL (20 ºC)
Easy to dissolve in ethanol, non-volatile oils, and fat solvents, insoluble in water; It has photosensitivity and needs to be stored away from light.
Synthetic and Natural Sources
Prepared by automatic oxidation reaction of linoleic acid methyl ester oxide.
It is the main product of linoleic acid lipid peroxidation, especially generated in large quantities during the heating process of vegetable oils such as soybean oil and rapeseed oil.
Reactive activity
Containing conjugated double bonds and aldehyde groups, it is easy to further oxidize to form derivatives such as epoxydecenal, hexanal, benzaldehyde, etc., which affect the flavor of food.
Main applications and functions
Essence field
Core function: As a key ingredient of chicken essence, it can provide fat aroma of fried or roasted chicken.
Other essence deployment: combine with pyrazine compounds to enhance the fat flavor of French fries; It is used in peanut, sesame oil and chocolate essence to enhance the aroma of nuts and oils.
Food flavor enhancement
In fried foods, its concentration is positively correlated with heating temperature and time, and is the main contributor to the frying aroma.
The flavor threshold is extremely low (0.00004-0.0023 mg/m ³ in the air), and a small amount can significantly enhance the aroma of food.
Derivative action
Oxidation products such as hexanal (green grass fragrance), benzaldehyde (apricot kernel fragrance), etc. can synergistically form complex flavors (such as meat fragrance) with other compounds.
