The microstructure and physicochemical properties of large yellow croaker (Larimichthys crocea) fish frozen by air freezing (AF, -20 °C) and liquid nitrogen spray freezing (LNSF) at -20, -60, and -100 °C, during frozen storage at -30 °C were evaluated. LNSF at -100 °C resulted in small and uniform ice crystals with a significantly (P <
0.05) lower cross-sectional area (187 μm
