What It Is

This compound belongs to the furfuryl sulfide family, sulfur-containing furan derivatives that form during Maillard browning reactions in cooked and roasted foods. Compounds in this family are valued in flavor chemistry for roasted, meaty, coffee-like character and are used at trace levels in savory and grilled-flavor systems.
