| Difurfuryldisulfide Usage And Synthesis |
| Chemical Properties | 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. |
| 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. |
