Application:
trans,trans-2,4-Heptadienal (CAS: 4313-03-5) retards or prevents the development of "off-flavors" in auto-oxidizing fats and oils. May be prepared by reduction with LiAlH4 of the dienoic acid prepared by the Doebner synthesis, followed by oxidation with Mn02 of the resulting dienol to the corresponding dienol; by the method of Marshall and Whiting. trans,trans-2,4-Heptadienal has a fatty, green odor In auto-oxidizing fats and oils, it retards or prevents the development of "off-favors". It is a specific marker of oxidative rancidity. It is also a potential algal metabolite. trans,trans-2,4-Heptadienal Can be used for mouthfeel in a variety of dairy-type flavors, as well as enhancing citrus flavors, especially orange and tangerine.
