Definition of furfural in English: furfuralnoun ˈfəːf(j)əralˈfərf(j)əˌræl mass nounChemistry A colourless liquid used in synthetic resin manufacture, originally obtained by distilling bran. 〔化〕糠醛，呋喃甲醛 An aldehyde derived from furan; chemical formula: C₄H₃OCHO Example sentencesExamples - Upon further heating, the sucrose forms hydroxymethyl furfural, which polymerizes into a the brown pigments that give color and flavor to the brittle.
- On the toxicity of furfural, I quoted from page 109 of the scoping report: ‘A particular chemical of concern that will be produced by the plant is furfural.’
- This suggests that the reaction takes place in the water phase and that substituted furfurals enter this phase only with difficulty.
- The process occurred by electrochemical oxidation of furfural under current or potential control.
- The furfurals, for instance, which have a bitter flavour when originally extracted, are transformed by the yeasts into compounds which have a range of flavours from smoked meat to leather.
- In recent years it has been shown that reductones, furfurals and other related substances formed in heated milk are sugar fission products 1,2.
- Glucose loses two water molecules and rearranges to form hydroxymethyl furfural, which polymerizes into brown pigments that add flavor and color to the candy.
- This research concentrates mainly on the market potential for furfural and phenolic compounds and examines some of the features of new processing technologies that offer cost advantages.
- Johann Doebereiner,, a German chemist accidentally discovered furfural in 1832 when he treated sugar with sulfuric acid and manganese dioxide.
- The liquor undergoes a process of further evaporation and fermentation to remove volatile compounds like methanol, furfural and ethanol.
- However, such conditions also result in the formation of furfurals from glucose and xylose.
- Aldoses generally exist in solution as pyranoses, whereas ketoses generally exist as furanoses, hence the ability of ketoses to rapidly dehydrate to yield furfurals.
OriginLate 19th century: from obsolete furfurol (in the same sense) + -al.
