Furaneol, or strawberry furanone, is an 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
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 an important component of the odours of buckwheat,[5] and tomato.[6] Furaneol accumulation during ripening has been observed in strawberries and can reach a high concentration of 37 μg/g.[7]
Stereoisomerism
Furaneol has two enantiomers, (R)-(+)-furaneol and (S)-(−)-furaneol. The (R)-form is mainly responsible for the smell.[8]

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