摘要: 为研究柠檬果皮的香气特征和加强柠檬感官品质的调控,以同一生长环境的3个不同柠檬品种(粗柠檬、尤力克柠檬和北京柠檬)的果皮为研究对象,采用顶空固相微萃取技术联合运用气质联用技术进行果皮香气成分的分析测定,以内标法进行定量。分别检出尤力克柠檬、北京柠檬和粗柠檬各有67、65种和65种香气组分,主要有烯烃类、醇类、醛类、酯类和酮类物质。结果表明:柠檬感官品质的差异除了受环境的影响外,基因型的不同也起到决定性作用;尤力克柠檬比北京柠檬和粗柠檬具有更高的感官品质。

Abstract: The aroma components from lemon peels of different varieties such as rough lemon, eureka lemon and meyer lemon grown in same condition were detected and analyzed by solid phase micro-extraction (SPME) coupled with GCMS. Semi-quantitative evaluation of aroma components were carried out by comparing peak area of each compound and its internal standard. The results showed that 67, 65 and 65 flavor compounds were identified in the peels of eureka lemon, meyer lemon and rough lemon, respectively. Volatile compounds mainly included sesquiterpene hydrocarbons, alcohols, aldehydes, esters and ketones. The difference of aroma compounds in lemon was determined by genotype. Therefore, eureka lemon has higher sensory quality than meyer lemon and rough lemon.
