    Palm oil (PO) and fully hydrogenated palm oil (FHPO) were subjected to enzymatic
    interesterification using 9.5% of TLIM Lipozyme. The optimum condition for this process
    occurred at 62.75°C, with reaction time 172.50 minutes with the ratio of 1:1 for palm oil to
    hydrogenated palm oil respectively. The Palmitoyl-Oleoyl-Stereoyl (POS) yield obtained
    was approximately 15%. Product was subsequently subjected to a fractionation process
    at various cooling temperatures and reaction time. At 34°C, POS achieved was at the
    highest level which was approximately 31% after 12 hours cooling process. The study of
    physiochemical properties of the Cocoa butter Equivalent (CBE) fat was determined for the
    purpose of characterization identification. The properties identified were solid fat content,
    slip melting point (SMP) and iodine value (IV). The IV and SMP values obtained were
    44.30 and 29°C respectively. However, CBE produced almost 0% of Solid Fat Content
    (SFC) at 30°C. Apart from the high yield of POS, the physicochemical characteristics
    showed significant compatibility with that of CB. In addition, the crystal polymorph of
    CBE 34 physicochemical characteristics of CBE34 (β′+β) was similar to CBE. Hence, from
    this study, CBE 34 is recommended for utilization in the confectionery industry as CBE.
