摘要: 以佛手鲜果及其腌制品为原料,通过超声波辅助水蒸气蒸馏技术,提取鲜佛手及其腌制品的挥发性物质,运用气相色谱-质谱联用技术对挥发性物质进行分析。结果表明:两种佛手挥发性物质提取率分别为0.76%和0.32%;新鲜佛手挥发性物质鉴定出31种化合物,其中以(Z)-2,3-丁二醇、(E)-2,3-丁二醇、D-柠檬烯、松油烯、α-松油醇、橙花醇、反式香叶醇等为主;在腌制过程中,不饱和烯烃类化合物损失较大,含量明显下降,其中有6种未检出;但糖类发酵导致(Z)-2,3-丁二醇、(E)-2,3-丁二醇的含量明显增加,这是佛手腌制后具有浓郁香甜风味的原因。

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, α-terpineol, 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)-2,3- butanediol showed a notable increase as a result of carbohydrate fermentation, which was responsible for the strong sweet flavor of cured bergamot.

Key words: bergamot, volatile fragrant compound, GC-MS
