Common Name

Dihydromaltol

Description

Dihydromaltol is a member of the chemical class of furanones, specifically classified as 2,3-dihydro-5-hydroxy-6-methyl-4H-pyran-4-one. Its chemical structure features a furan ring with hydroxyl and methyl substituents, contributing to its distinct aroma profile. Dihydromaltol is identified as a significant odorant in various food products, including dairy items like Ryazhenka kefir, where it was detected through GC-olfactometry-MS techniques (PMID:19817423 ). Additionally, it plays a role in the flavor profile of roasted chicory, alongside other caramel- and sweet-smelling compounds (PMID:30969122 ). The compound is also noted for its formation during the aging of sweet fortified red wines, influenced by oxidative conditions, which distinguishes it from other related compounds formed under different conditions (PMID:10552573 ). Dihydromaltol is involved in metabolic pathways that contribute to the synthesis of various aroma compounds, enhancing sensory experiences in food and beverages (PMID:706805 ). Its presence and characteristics make it an important focus in flavor chemistry and food science.
