Colorless to light yellow liqui | [Occurrence]
Reported found in beef (boiled, cooked) and coffee | [Uses]
Furfuryl disulfide has been used in the preparation of poly(disulfido-imide)s by Diels-Alder (DA) reaction with the various bismaleimides. | [Definition]
ChEBI: Bis(2-furanylmethyl) disulfide is a heteroarene. | [Preparation]
Difurfuryl disulfide is produced from Furfural and Hydrogen sulfide gas. | [Taste threshold values]
Taste characteristics at 20 ppm: roasted, sulfuraceous, alliaceous, green and meaty. | [General Description]
Difurfuryl disulfide is a sulfur-containing volatile compound mainly found in roasted coffee. It is also the main degradation product of furfuryl mercaptan under Fenton-type reaction conditions. |
