Furaneol Usage And Synthesis
  • DescriptionFuraneol 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.
  • Chemical PropertiesFuraneol 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.
  • Chemical Propertieswhite to light yellow crystal powde
  • Chemical Properties4-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.
  • Chemical PropertiesFuraneol has a sweet, fruity, strawberry, hot sugar, fruity caramel or “burnt pineapple” aroma.
  • OccurrenceReported 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.
  • Uses2,5-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.
  • DefinitionChEBI: 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.
  • PreparationFuraneol 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. The reaction product is cyclized, alkylated, hydrolyzed, and decarboxylated .
