OCCURRENCE AND FORMATION OF DAMASCENONE, TRANS‐2,6,6‐TRIMETHYL‐l‐CROTONYL‐CYCLOHEXA‐1,3‐DIENE, IN ALCOHOLIC BEVERAGES

摘要

ABSTRACTThe aroma compound, damascenone, was found in many alcoholic beverages such as whiskey, brandy, rum, wine, and beer, and was considered to be significant to flavor. Damascenone in whiskey was formed from its precursor that came from barley during distillation. Beer contained none or very little, but it was formed by heating. In brandy production damascenone was present in grape and wine together with its precursor, and the precursor changed to it during distillation. It was also found in cane molasses.
