Metabolite Identification
Common NameFilbertone
DescriptionFilbertone, also known as 5-methylhept-2-en-4-one, is a member of the class of compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR'. Filbertone is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Filbertone is a sweet, filbert, and hazelnut tasting compound found in common hazelnut, which makes filbertone a potential biomarker for the consumption of this food product. Filbertone is the principal flavor compound of hazelnuts. It is used in perfumery and is designated as generally recognized as safe (GRAS) for use in foods .
