The aim of the study was to determine the resistance to crystallization of palm olein (POo) with soybean oil (SBO) at different temperatures. POo of iodine value (IV) 65 gave better resistance to crystallization than POo of IV 60 or IV 63. For applications such as salad oil, the use of POo of IV 65 is limited to 30% when blended with SBO. If POo of either IV 60 or IV 63 is chosen, its use in salad oil is limited to 10% only. However, for applications other than salad oil, such as for cooking or frying, 100% POo of any IV could be used. For cold climates, the amount of POo (IV 60 or 63) recommended to get a clear oil is 10-30%. Alternatively, up to 40% POo of IV 65 can be blended with SBO. For temperate climates, the amount of POo (IV 60 or 63) recommended can be up to 60%. With POo of IV 65, the amount recommended is as high as 80-90% for application as a cooking or frying oil.
