In this study an attempt was made to investigate the effect of low and
high concentrations of enzymatically synthesized PB-DAG (with purity of
90% w/w) on crystallization kinetics of PO. Effect of PB-DAG on
isothermal crystallization properties of PO depended upon the concentration
of PB-DAG. Addition of 2 and 5% of PB-DAG decreased
(insignificantly and significantly, respectively) nucleation rate, crystallization
rate and, crystal growth mode of PO. Low concentration of PB-DAG
(10%) can be considered to be of technical interest, and it might thus be
used as β'-stabilizing agent in palm-based products. However, addition of
30 and 50% of PB-DAG increased significantly (Pb0.05) nucleation and
crystallization rate, and also changed significantly (Pb0.05) crystal
growth mode of PO even with similar supercooling ranges as reflected in
the corresponding Avrami parameters.
