General description

1-Octen-3-ol occurs naturally in mushrooms. It is the most prominent odor volatile produced by fungi such as Aspergillus, Penicillium and Fusarium species. 1-Octen-3-ol is also formed in major quantity when soybeans are soaked in water as a pretreatment before soymilk production. It is also a potent mosquito attractant. 1-Octen-3-ol is the major volatile compound formed during autoxidation of linoleic acid.
