Extraction of collagen from catfish (Clarias gariepnus) waste and determination of its physico-chemical properties / Normah Ismail and Nurul Asyiraf Abdul Jabar

Collagen was extractedfrom catfish (Clarias gariepnus) waste using 0.5M acetic acid and its subsequent precipitation in 2.6M NaCI. The resultant collagen was analysed with respect to its moisture content and physicochemicalproperties including yield, pH, protein content, colour, odour and thermal st...
