一般描述
4-Hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF, DMHF) is a caramel-like smelling compound, identified in Maillard reaction systems based on pentoses by GC-MS and GCMS/MS. Solubility data of DMHF in six different solvents over the temperature range from 283.15K to 313.15K under atmospheric pressure of 0.10 MPa has been examined by dynamic method. Separation of the enantiomers of DMHF by capillary electrophoretic method has been reported. Commercially it is synthesized from L-rhamnose. DMHF has been identified as acidic odorant in Thai premium fish sauce samples by aroma extract dilution analysis (AEDA). It is identified as key aroma compound in the distiller′s grains (DG) from wheat. It is reported as the main flavor compound in strawberries and its biosynthesis has been reported. HDMF has been found in various fruits such as pineapples strawberries and grapes, as well as in beef broth , roasted coffee, bread crust, roasted beef, roasted sesame seeds and stewed beef.
