4,5-Dimethyl-3-hydroxy-2,5-dihydrofuran-2-one Chemical Properties,Usage,Production

  • Chemical Properties clear yellow liquid
  • Chemical Properties 3-Hydroxy-4,5-dimethyl-2(5H)-furanone was found in, for example, fenugreek, coffee, sake, and florsherry. Its aroma characteristic changes from caramel-like at low concentrations to curry-like at high concentrations. A method described for its preparation comprises condensation of ethyl propionate with diethyl oxalate and reaction of the intermediately formed diethyl oxalylpropionate with acetaldehyde. Acidic decarboxylation of the ethyl 4,5-dimethyl-2,3-dioxodihydrofuran-4-carboxylate gives the title compound.
  • Occurrence Reported found in roasted Virginia tobacco, beef broth, beer, sherry, botryized wine, coffee, tea, fenugreek, sake and rice wine.
  • Aroma threshold values Aroma characteristics at 1.0%; sweet, strong brown, cyclotene and maple like, caramel, toffee, maltol-like and burnt, brown sugar fenugreek-like, cooked and syrupy.
  • Taste threshold values Taste characteristics at 5–25 ppm; sweet, caramel, maple, walnut, brown sugar, nutty, cotton candy, fenugreek and celery-like, rum, roasted meaty with a honey nuance
