The addition of sucrose behenate modified the liquid phase of
the soft fats used in this study. The effect of the emulsifier on the
solid profile was proportional to the quantity of the liquid phase
of each fat, with greater changes observed in the interesterified fat. Sucrose behenate was also able to modify the hardness of the
fats, providing them greater thermal resistance. In this case, palm
oil and palm mid fraction showed greater hardness values with
the addition of sucrose behenate, while for the interesterified fat,
the hardness was greater only at 25 C. The results indicated that
sucrose behenate influenced the crystallization kinetics in the fats
only at 20 C, but did not cause any differences at 25 C. The addition
of sucrose behenate caused large differences in the structure
of the crystalline network of the fats. At 20 and 25 C the polymorphic
differences caused by the presence of sucrose behenate indicated
a delay in the a?b transition for the interesterified fat. At
25 C, it was observed the initial formation of b crystals in palm
oil, while no change was observed in the polymorphic behavior
of palm mid fraction in both temperatures.
