Gelatin is widely used food and non-food industries such as pharmaceutical
application. Generally, gelatin is obtained from mammals. The fish gelatin represents
one of the important types of gelatin from other sources other than mammalian gelatin
and it may thus be considered as an alternative to mammalian gelatin for use in
various food and pharmaceutical applications. The main objective of the study is to
extract the gelatin from head and skin of catfish (Clarias gariepinus). Gelatin extracted
by alkaline and acid pre-treatments and confirmed by FTIR analysis and Scanning
Electron Microscopy. The physicochemical properties were studied. The skin of catfish
yielded higher amount of gelatin than the head which is 14.56% and 6.25%
respectively. The proximate analysis were conducted to study the ash and moisture
content in extracted gelatin. The result shows higher content of moisture (5.67%) in
skin while ash content (0.52%) in head.
