摘要: 为了解不同成熟期芒果香气的变化,采用热脱附-气相色谱/质谱(TCT-GC/MS)联用技术,对动态顶空密闭循环吸附捕集的商熟期、完熟期样品挥发物进行分析检测。结果表明,芒果香气成分中富含酯类化合物,商熟期的果肉和果皮挥发物均较完熟期含有更多种类的萜烯类成分;此外,果皮香气中均含异巴豆酸乙酯(商熟期3.01%、完熟期5.68%),而在果肉中则已转化为巴豆酸(商熟期0.16%)或异巴豆酸(完熟期4.15%)。

Abstract: The volatiles of "Xiaosannian" mango fruits from China’s Yunnan province at commercial ripe stage (CRS) and full ripe stage (FRS) were captured in airtight head-space vials by dynamic adsorption method respectively,and then analyzed by using thermal-desorption cold trap gas chromatography/mass spectrometry (TCT-GC/MS). The results showed that esters are rich in the volatiles of" Xiaosannian" mango fruits at both CRS and FRS. Terpenes content is higher in the volatiles of both mango pulp and peel at CRS than at FRS. Methacrylic acid ethyl ester exists in the volatiles of mango peel at both CRS (3.01% )and FRS (5.68%),which is transformed into crotonic acid (0.16% at CRS) or isocrotonic acid (4.15% at FRS) in mango pulp.

Key words: mango fruit, volatile, thermal-desorption cryo-trapping gas chromatography/mass spectrometry (TCT-GC/MS), crotonic acid
