摘要:

以嘎拉苹果为试材,使用电子鼻和气相色谱-质谱联用技术研究其在20 ℃贮藏期间芳香品质的变化。电子鼻检测结果表明,通过线性判别分析,可以将不同贮藏期的苹果区分开。气相色谱-质谱检测结果表明,嘎拉苹果在采后贮藏期间的主要挥发性成分为己醛、(E)-2-己烯醛、乙酸丁酯、乙酸-2-甲基丁酯、乙酸己酯、2-甲基丁酸己酯、1-丁醇、2-甲基-1-丁醇、1-己醇、草蒿脑和α-法尼烯。将检测到的主要挥发性芳香物质进行主成分分析和线性判别分析,结果表明,通过气相色谱-质谱分析可以区分不同贮藏期的苹果果实。

Abstract:

The aroma quality of Gala apple during storage at 20 ℃ was evaluated by electronic nose and gas
chromatography-mass spectrometry (GC-MS). The obtained data from electronic nose were analyzed using linear
discriminant analysis. The results showed that linear discriminant analysis (LDA) could successfully discriminate Gala apple
with different storage periods. Meanwhile, based on principal component analysis (PCA) and linear discriminant analysis,
GC-MS could distinguish Gala apple from different storage periods.

Key words: electronic nose, gas chromatography-mass spectrometry, apple, aroma quality
