Furaneol, or strawberry furanone, is a organic compound used in the flavor and perfume industry. It is formally a derivative of furan. It is a white or colorless solid that is soluble in water and organic solvents.[2]

Odor and occurrence[edit]

Although malodorous at high concentrations, it exhibits a sweet strawberry aroma when dilute.[2] It is found in strawberries[3] and a variety of other fruits and it is partly responsible for the smell of fresh pineapple.[4] It is also important for odour of buckwheat,[5] and tomato.[6]


It is one of several products from the dehydration of glucose. Its immediate biosynthetic precursor is the glucoside, derived from dehydration of sucrose.[2]
