Elucidating Volatile Flavor Profiles and Metabolic Pathways in Northern Pike (Esox lucius) During Superchilled Storage: A Combined UPLC-Q-TOFMS and GC-MS Approach

Temperature is the most critical factor in fish preservation. Superchilled storage represents a novel technology that effectively retards quality deterioration in aquatic products. This study investigated the flavor variation patterns and deterioration mechanisms in 16 north- ern pike (Esox lucius) samples during superchilled storage (−3 ◦C) based on analysis using gas chromatography-ion mobility spectrometry (GC-IMS) and ultra-performance liquid chromatography–quadrupole time-of-flight mass...
