| Glucose loses two water molecules and rearranges to form hydroxymethyl furfural, which polymerizes into brown pigments that add flavor and color to the candy. |
| The Committee agreed to revoke the food additive specifications for furfural. |
| The liquor undergoes a process of further evaporation and fermentation to remove volatile compounds like methanol, furfural and ethanol. |
| Two substances, furfural and glyoxal, are produced naturally in the environment as a combustion product of burned wood. |
| Downstream processes convert the output into marketable products such as fuel ethanol, lignin, furfural and acetic acid. |
| But we don't worry about the furfural in an apple, because the dose really is so small. |
