Insect Utilization and Effects

The effects of different freezing treatments on the quality changes of bighead carp heads were evaluated in terms of pH value, TBARS, TVB-N, K-value, biogenic amine, total aerobic counts (TACs), drip loss, cooking loss and electrical conductivity (EC) during ice storage. Fish heads were stored at −40 °C (T1), −40 °C for 12 h and then −18 °C (T2), −18 °C (T3) for 3 months prior to ice storage. No significant differences were observed among T1, T2 and T3 for drip loss, cooking loss and EC (p > 0.05). T2 showed lower TACs, pH value, TBARS and TVB-N than T3 did. Significant lower value of spermine and spermidine were observed in T1, T2 and T3 than those of control group (fresh) from 9th to 18th day (p < 0.05). Drip loss was significantly correlated with TBARS, pH value, TVB-N, and TACs in groups T1, T2 and T3 (p < 0.05).
