Volatile organic compounds are important indicators of the characteristic flavor of traditional fermented fish products. In the present study, gas chromatography-ion mobility mass spectrometry (GC-IMS) and gas chromatography-mass spectrometry (GC-MS) were used to identify and quantify the volatile organic compounds (VOCs) in fermented sea bass. Thirty-six and 104 VOCs were identified by GC-IMS and GC-MS, respectively. Aldehydes were the principal contributors to the formation of the overall flavor of fermented sea bass. The characteristic VOCs in fermented sea bass were identified based on loading plots. GC-IMS and GC-MS, along with variable influence on projection (VIP), identified six and four VOCs as biomarkers, respectively, in fermented sea bass. This investigation demonstrated that GC-IMS could rapidly detect VOCs in a simple manner in fermented sea bass. The results of the present study also provide a theoretical basis for determining flavor formation in fermented sea bass.
