LC-Q-TOF-MS/MS data of phyllobilins in apple peels cv. 'Gala' during ripening under shelf-life conditions.

During senescence and ripening, higher plants degrade the green pigment chlorophyll to linear tetrapyrrols, referred to as phyllobilins (PBs). This dataset provides chromatograms and mass spectral data of PBs acquired from methanolic extracts of cv. Gala apple peels at five different shelf life (SL) stages. Data were obtained using a (ultra-high) pressure liquid chromatograph (UHPLC) coupled to high resolution quadrupole-time of flight-mass spectrometer (HRMS-Q-TOF). A data-dependent inclusion list (IL) ex professo containing all known masses of PBs was applied to address PBs, and fragmentation patterns were studied to confirm their identity operating a MS2 method. Mass accuracy was set to 5 ppm for parent ion peaks, this parameter was adopted as inclusion criterium. The detection of PBs' appearance during ripening can be helpful for assessing the quality and maturity of the apples.
