Effect of combined chitosan coating and modified atmosphere packaging on the storability of cold-stored rice field eel (Monopterus albus) fillets
After being caught and filleted,fresh rice field eel fillets were impregnate with chitosan coating solutions,and then stored in modified atmosphere package (MAP) (60%CO2 + 40%N2) at 2 ℃ for up to 25 days to determine the chemical,biochemical and physical changes.Fillets were left untreated (CN),or were treated with chitosan coating (CC),or combined chitosan coating with MAP (CCM).Total plate count (TPC),trimethylamine (TMA-N),total volatile bases (TVB-N),pH,colour,water loss,colour changes and hardness were monitored periodically.The results indicated that coating and MAP treatments retard the decay of fish compared to untreated samples.CCM more efficiently inhibited the growth of TPC (2-2.6 Log reductions during Astorage) than did CN and CC.CCM treatments predominantly reduced chemical spoilage,reflected in TVB-N,pH,and TMA-N,retarded water loss and maintained colour and hardness.
