Providing a frozen non-water-washed or water-washed at low level fish meat with suppressed freezing denaturation, from a fish species generally never used without water-wash. Biological iron, iron-containing substances and/or biological reducing substances in the fish meat are oxidized. A frozen non-water-washed or water-washed at low level fish meat made from minced fish meat or the dehydrated minced fish meat, where one or more cryoprotectants have been added and the decomposition of trimethylamine-N-oxide is suppressed through oxidation. Preferably, the fish meat is put in contact to oxygen under agitation of the fish meat, to thereby suppress trimethylamine-N-oxide decomposition, to which are added cryoprotectants for freezing. A frozen product of non-water-washed or water-washed at low level fish meat, where salts have been added for such agitation, followed by agitation. A fish paste product from the frozen product as the raw material.
