Furthermore, the triacylglycerol
(TAG) profile of palm oil is very heterogeneous, with different
possible combinations of saturated and unsaturated fatty acids
with distinct carboxylic chain length, favoring the development of
complex isothermal crystallization profiles with polymorphic diversifications.
Therefore, palm oil undergoes different polymorphic
events during crystallization and the transition from the a Form
Crystal to the b0 Crystal in palm oil is extremely slow compared to
most other natural fats . The polymorphism of lipid crystal and the crystallization
processes affect the hardness, texture, rheology, and spreadability
of lipid-based solid products
