Abstract:
Collagen extracted individually from the muscle, skin and waste comprising bones and viscera of Chanos chanos was partially purified and fractionated to acetic acid soluble collagen (ASC) and pepsin digestible collagen (PDC). Fish waste had only ASC while skin and muscle had small amounts of PDC in addition to ASC. The yield of partially purified ASC and PDC were 0.38 and 0.09% respectively from muscle and 20.14 and 5.6% from skin. Yield of ASC from waste was 0.2%. Total nitrogen, amino acid composition, electrophoretic pattern and approximate molecular weight of the partially purified collagens are reported
