Abstract
The volatile compositions of fresh and cured bergamot were analyzed by ultrasonic-assisted steam distillation coupled with GC-MS.The extraction rates of essential oil from fresh and cured bergamot were 0.76% and 0.32%,respectively.A total of 31 compounds were identified from fresh bergamot and(Z)-2,3-butanediol,(E)-2,3-butanediol,D-limomene,terpinene,αterpineol,neroli and trans-geraniol were predominant among them.During the process of curing,the loss of unsaturated alkenes was remarkable,and 6 unsaturated alkenes showed undetectable levels.However,the contents of(Z)-2,3-butanediol and(E)-2,3butanediol showed a notable increase as a result of carbohydrate fermentation,which was responsible for the strong sweet flavor of cured bergamot.关键词
