ABSTRACT
Crystallization
behavior and kinetics study of palm kernel oil (PKO) were investigated
using differential scanning calorimetry (DSC) by controlling cooling and
reheating rate within a certain range of temperature. The evolution of
morphology and particle counts was analyzed by focused beam reflectance
measurement (FBRM) and particles video microscope (PVM) at the
nucleation stage during suspension crystallization. The particle counts
and morphological evolution from needle-like aggregations to amorphous
form from PVM were observed during the initial crystallization stage,
which meant that a phase transition was likely to occur. This work can
give a better understanding of complicated fat system crystallization
behavior and provide some critical instructions to control fractionation
process.
