| Abstract: | Kinetics of cocoa butter equivalent (CBE) production from palm oil midfraction (POMF) and stearic acid methyl ester (SAME) by interesterification catalyzed in solvent free system was studied. Two kinetic models were established and to predict the relationship between initial reaction rates and substrates concentrations. The concentrations of three major triglycerides during the reaction process could be estimated. It has beed proved that the models fit the experimental data well. |
