Abstract:
To explore the effects of irradiation and fermentation on the flavor of cherry juice, this study characterized the volatile components of cherry juice by gas chromatography-mass spectrometry (GC-MS), gas chromatography-ion mobility spectrometry (GC-IMS) and comprehensive two-dimensional gas chromatography-mass spectrometry (GC × GC-MS) combined with machine learning techniques. Electron beam irradiation (EBI) increased concentrations of benzyl alcohol, methyl heptanoate and methyl butanoate in C + EBI. Fermentation increased concentrations of 3-methylphenol, linalool, and ethyl 2-hydroxy-4-methylpentanoate in C + EBI + F. The 2 kGy + F treatment yielded optimal flavor quality, with 2-nonanone, 2-tridecanone, levomenthol, and 2-undecanone serving as key markers, contributing floral, fruity, tart, and minty notes. For efficient aroma profiling, PLS-DA identified 17, 22 and 36 key features in the GC-MS, GC-IMS and GC × GC-MS datasets, respectively. These features were used in machine learning models, with the NBM model showing the best classification and prediction performance.

Gas chromatography (GC) is used to separate and detect small molecular weight compounds in the gas phase. The sample is either a gas or a liquid that is vaporized in the injection port. Typically, the compounds analyzed are less than 1,000 Da, because it is difficult to vaporize larger compounds. GC is popular for environmental monitoring and industrial applications because it is very reliable and can be run nearly continuously....
