Using different protein enzymes with different extraction methods can lead to improve the yield of protein hydrolysis. In this review we studied the effect of different drying methods on chemical composition of bighead carp. Ficin enzyme was studied as proteolytic enzyme of fig latex. Whereas the properties of papain and bromelin have been quite thoroughly studied, relatively little is known about the properties of ficin. Also used different methods of extraction to show the effect of extraction on protein hydrolysis, this study highlights many of protein and peptides fractionation, such as electrophoresis and high-performance liquid chromatography (HPLC), which have experienced significant development over the past few years. http://pubs.sciepub.com/jfnr/8/11/5/jfnr-8-11-5.pdf drying bighead carp enzyme proteolytic hydrolysis extraction fractionation
