• Beschreibung

  Furaneol is a very important aroma chemical and is a key flavoring compound found in many kinds of fruits. It can be chemically formed through different carbohydrates during the Mainlard reaction. It can also be synthesized by yeast, bacteria and plants and play some physiological effects. Study has shown that it can suppress the phosphorylation of cAMP response element binding protein, underlying its potential role as an effective inhibitor of hyperpigmentation. It also has the potential to become an effective antimicrobial agent for human beings.

• Chemische Eigenschaften

  Furaneol has a sweet, fruity, strawberry, hot sugar, fruity caramel or “burnt pineapple” aroma.

• Chemische Eigenschaften

  Furaneol is a constituent of pineapple and strawberry aroma and is also found in other foods. It forms colorless crystals (mp 77–79°C) with a relatively weak, nonspecific odor. Dilute solutions develop a pineapple, strawberrylike odor.

• Chemische Eigenschaften

  4-Hydroxy-2,5-dimethyl-3(2H)-furanone has a fruity caramel or "burnt pineapple" aroma. May be synthesized from dimethyl- 3,4-dihyroxyfuran-2,5-dicarboxylate.

• Chemische Eigenschaften

  white to light yellow crystal powde

• Occurrence

  Reported found in guava, grapes, pineapple, raspberry, strawberry fruit and jam, rye bread, Swiss cheese, boiled beef, beer, cocoa, coffee, tea, filberts, almonds, oatmeal, Arctic bramble, yellow passion fruit, mango, shoyu, fermented soy sauce, litchi, malt and Cape gooseberry.

• Verwenden

  2,5-Dimethyl-4-hydroxy-3(2H)-furanone is a component of meat essence composition. 2,5-Dimethyl-4-hydroxy-3(2H)-furanone is used in the flavor and perfume industry due to its sweet strawberry aroma.

• Definition

  ChEBI: A member of the class of furans that is 2,5-dimethylfuran carrying additional oxo and hydroxy groups at positions 3 and 4 respectively. It has been found particularly in strawberries and other such fruits.

• synthetische

  Furaneol can be prepared by cyclization of hexane-2,5-diol-3,4-dione in the presence of an acidic catalyst.The dione is the ozonization product of 2,5- hexynediol, which is obtained by ethynylation of acetaldehyde.
  In another process, a dialkyl ??-methyldiglycolate (formed from an alkyl lactate and an alkyl monochloroacetate) is reacted with dialkyl oxalate in the presence of a sodium alkoxide and dimethylformamide. The reaction product is cyclized, alkylated, hydrolyzed, and decarboxylated.In another process, a dialkyl ??-methyldiglycolate (formed from an alkyl lactate and an alkyl monochloroacetate) is reacted with dialkyl oxalate in the presence of a sodium alkoxide and dimethylformamide.

• Allgemeine Beschreibung

  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.
