ABSTRACT

The experiment was conducted to determine the yield, physical and chemical composition of leaf protein concentrates and bagasse obtained from oil palm leaf using three different processing methods. The process of extraction were heat coagulation, acid coagulation, and alum precipitation methods. The leaf protein concentrates and bagasse obtained were further analysed for their chemical and mineral compositions.

The yield of LPC and bagasse obtained from acid coagulation, alum precipitation, and heat precipitation were comparable. But, the yield of OLPC was not significantly (p>0.05) different in the acid and alum processing methods, but was significantly (p<0.05) different for the heat processing method. Result, from the chemical analysis shows that the CP and EE of acid coagulation method were significantly (p<0.05) different from alum and heat processing methods. At the same time, the MC and NFE of OLPC for heat were significantly (p<0.05) different from alum precipitation method and acid coagulation method.
