  • 4-Hydroxy-5-methyl-2,3-dihydrofuran-3-one and methods of making and using the same
    Patent number: 4013800
    Abstract: 4-Hydroxy-5-methyl-2,3-Dihydrofuran-3-one is produced by Maillard reaction between xylose, ribose or arabinose with glutamic acid, aspartic acid, alanine, glycine, proline or salts of these amino acids, and may be recovered in crystalline form from the reaction mixture by steam distillation, evaporation of the distillate at temperatures not higher than 40.degree. C, and sublimation from the oily residue at or above 80.degree. C. The compound imparts a pleasant maltol-like flavor to ingestible products such as food, drinks, but also compositions for oral hygiene. The crude Maillard reaction mixture containing the compound may be employed as a flavoring if prepared from glutamic acid, aspartic acid or their salts and from xylose or xylan.
