| Description | Description: 3-Hydroxy-4,5-dimethyl-2(5H)-furanone or sotolone is key flavoring compound found in raw cane sugar, aged sake, coffee, fenugreek, lovage and wines. Sotolon (also known as sotolone) is a lactone and an extremely powerful aroma compound, with the typical smell of fenugreek or curry at high concentrations and maple syrup, caramel, or burnt sugar at lower concentrations. In 1999 it was shown that sotolone is the cause of the odor found in patients with maple syrup urine disease (MSUD) - PMID 10234605 . This compound was found in the urine of 7 MSUD patients but was undetectable in normal individuals. 3-Hydroxy-4,5-dimethyl-2(5H)-furanone belongs to the family of Butenolides. These are dihydrofurans with a carbonyl group at the C2 carbon atom. |
