Evaluation of the quality of chilled and frozen African catfish ( Clarias gariepinus Burchell, 1822) fillets

摘要

The quality of chilled and frozen African catfish fillets was compared. The experiment was performed on?20?individuals of Clarias gariepinus aged 1 year, with estimated body weight of 1 kg. A total of 40 right and left fillets were subjected to pre-treatment. Chilled right fillets (20) and left fillets (20) stored for 8 months in the freezer were subjected to quantitative and qualitative laboratory analyses. Chilled African catfish fillets had a lower of moisture content, higher of total protein, fat and crude ash, and higher energy value than frozen samples. Chilled fillets had also higher water-holding capacity, lower cooking loss and higher tenderness.
