3.1. Chemical composition
Oleic and linoleic acids were the main unsaturated fatty acids
present in the three fats. The interesterified fat showed the highest
levels of unsaturated fatty acids, and monosaturated (SUU) and triunsaturated
(UUU) triacylglycerides (TAGs), followed by palm oil.
On the other hand, the palm mid fraction exhibited a lower amount
of SUU and UUU TAGs (Table 1). SUU and UUU TAGs represent the
liquid phase of fat, implying that the interesterified fats contained
the greatest proportion of the liquid phase. The SFC depends on
TAGs composition, thus the percentage of saturated TAGs is also
very important. As shown on Table 1, the interesterified fat has
the lowest amount of SSS TAGs of the three samples, the smaller
this quantity, the smoother the fat.
