Citrus fruits are very popular food products. There are many species and varieties of them. There are also documented cases of some citrus fruits causing a severe allergic reaction. Some species of the citrus fruits, especially hybrid ones show a reduced allergenic effect due to the lack of seeds. There is a need for rapid methods for evaluation of citrus' botanical origin. During research, the headspace of three citrus fruits , and × was analysed using electronic nose based on ultrafast gas chromatography and gas chromatography with mass spectrometry. In the paper, two approaches were compared. The usefulness of an electronic nose to control the quality of hybrids was demonstrated. The results obtained during ultrafast gas chromatography analyses were subjected to statistical analysis. Four chemometric methods namely: principal component analysis (PCA), discriminant function analysis (DFA), soft independent modeling of class analogies (SIMCA), statistical quality control (SQC) were used to distinguish between limequat and its parent fruits. Electronic nose combined with chemometrics is a novel analytical tool for hybrid fruits' classification due to their botanical origin. It can supplement established techniques by providing results in a short time and at a low cost.
柑橘类水果是非常受欢迎的食品。它们有许多种类和品种。也有一些柑橘类水果引起严重过敏反应的记录案例。某些柑橘类水果品种，尤其是杂交品种，由于没有种子，其致敏作用有所降低。需要快速评估柑橘植物来源的方法。在研究过程中，使用基于超快速气相色谱和气相色谱-质谱联用的电子鼻分析了三种柑橘类水果的顶空。本文比较了两种方法。证明了电子鼻在控制杂交品种质量方面的有效性。对超快速气相色谱分析获得的结果进行了统计分析。使用主成分分析（PCA）、判别函数分析（DFA）、类类比软独立建模（SIMCA）、统计质量控制（SQC）这四种化学计量学方法来区分来檬金柑及其亲本水果。电子鼻与化学计量学相结合是一种用于根据杂交水果植物来源进行分类的新型分析工具。它可以通过在短时间内以低成本提供结果来补充现有技术。
