The addition of small amounts of hard fats to palm oil cause different responses on the product functional attributes, proportional to the amount added. PKO addition has no significant effect in the final product. The changes found in the lipid system containing PO, CO and SO are correlated to the increase in the content of saturated fatty acids, mainly C16:0 and C18:0 in blends. However, in blends with CR, this behavior is determined by the presence of TAGs greater than 54 carbons, which affect the melting profile and the consistency as well as promote an increase in SFC, leading to higher thermal stability of the fats when subjected to high temperatures. The addition of PO, CO and SO favor the modification of palm oil microstructure resulting in a blend of spherulites-type and disks-type crystals. Blends with CR favor disk-type microstructure, confirming that C22:0 accelerate this transformation. The results of this research recommend the addition of CO or SO at 3–5 g/100 g of blend, or only 1 g of CR/100 g of blend (or even less) to palm oil. These additives improve the most marketable functional attributes of products, without adverse effects, like for instance, a waxy residu
