2、GC–MS法检测分析其香气物质,共检测到154种香气物质,其中58种含量较为丰富。成熟期对果实香气物质的组成与含量有显著影响。随果实发育,芳樟醇、α–萜品醇、香叶醇、β–月桂烯、罗勒烯、2–己烯醇、苯乙醛和己醛的含量均迅速下降,而β–紫罗兰酮、香叶基丙酮、γ–癸内酯、δ–癸内酯和γ–十二内酯的含量迅速增加。果实发育前期以积累醇类、醛类、萜类和萜烯类为主,果实成熟过程中以积累酮类和内酯为主。果皮中萜类、萜烯类、醇、醛和内酯的含量均显著高于果肉中,而酮类物质的含量却显著低于果肉中。基于风味阈值法,共鉴别出新疆杏果实特征香气成分22种,其中芳樟醇、γ–癸内酯、
3、δ–十二内酯、β–大马酮、顺,反–2,6–壬烯醛、苯乙醛、己醛、α–萜品醇、乙酸己酯、香叶醇和β–月桂烯等的贡献最大。关键词:杏;果实发育;成熟;香气物质;风味中图分类号:S662.2文献标志码:A文章编号:0513-353X(2016)10-1878-13ChangesinAromaVolatilesofXinjiangApricotFruitDuringDevelopmentandRipeningandCharacterizationofKeyAromaComponents111121,3,*LUJuan-fang,ZHENGHui-wen,ZHEN
