Double fractionated palm olein samples of iodine value (IV) 60 (DfPOo IV 60) and IV 65 (DfPOo IV 65) were blended with sunflower oil (SFO) and high-oleic safflower oil (SAFO) in various proportions. The clarity of the blends was determined after storage at various temperatures. The maximum levels of DfPOo IV 65 that could be mixed with SFO and SAFO to give blends that remained clear for at least 240 days at 20 degrees C were 60% and 70% respectively. With DfPOo IV 60, the levels were 30% and 60% respectively. At 15 degrees C, with both SFO and SAFO the maximum levels were 20% with DfPOo IV 60 and 30% with DfPOo IV 65. At 10 degrees C, all blends containing 20% palm olein except DfPOo IV 60 -SFO and SAFO 20;80 remained clear for about 180 days. At 5 degrees C blends containing 10% palm olein and 90% SFO remained clear for 90 days. Blends of either SFO or SAFO with, up to 20% DfPOo IV 60 or 30% DfPOo IV 65 passed the cold test. Blending of SFO or SAFO with DfPOo improved the fatty acid composition in terms of the saturated; monosaturated; polyunsaturated ratio.KEYWORDS:
