Effects of different freezing treatments on the biogenic amine and quality changes of bighead carp (Aristichthys nobilis) heads during ice storage

► Effect of various freezing treatments on quality of bighead carp head was evaluated. ► A new freezing method for preservation of freshwater fish was established. ► Freezing at −40 °C 12 h and then −18 °C kept a good quality of fish head. ► Freezing at −40 °C 12 h and then −18 °C is a good freezing method on an energy-saving basis.
