固相微萃取GC-MS法测定苹果不同品种中主要芳香成分的研究

利用固相微萃取(solid phase nmicroelraction，SPME)和气质联用技术对目前果汁生产企业主要用于制汁的金帅、澳洲青苹、国光、新红星、富士及秦冠等品种的主要芳香成分进行定性和定量分析，比较不同品种之间芳香成分在种类和含量上的差异。在香气成分的定量分析中，以脱香果汁为基体加入混合标样，采用内标标准曲线法制作标准曲线，消除由SPME带来的系统误差，提高了实验结果的准确性和精确性。

Determination of Representative Aromatic Components in Different Breeds of Apple by GC - MS with Solid Phase Microextraction

Qualitative and quantitative analyses of representative aromatic components in differentbreeds of ap-ple suchas Goldendelicious,GrannySmith,Ralls,Starkrimson,Fuji and Qinguan bysolid phase microextrac-tion(SPME)withgas chromatography-mass spectrometry(GC-MS)were developed.Theyare the mainculti-vars for the production of apple juices in the juice-manufactured enterprises.The differences of aromatic com-ponents in different cultivars and contents were analyzed.The off-odor juice served as the matrixwas put in-to the mixed standard sample.The criterion curve was made by inner standard method to eliminate the system error from SPME and the accuracy and precision of results obtained were improved.
