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.

With DfPOo IV 60 the levels were 30 percent and 60 percent respectively. At 15 degree C with both SFO and SAFO the maximum levels were 20 percent with DfDPOo IV 60 and 30 percent with DfDPOo IV 65. At 10 degree C all blends containing 20 percent palm olein except DfPOo IV 60 -SFO and SAFO 20:80 remained clear for about 180 days.

Abstract

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 clariy 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 degree C were 60 and 70 percent respectively. With DfPOo IV 60 the levels were 30 percent and 60 percent respectively. At 15 degree C with both SFO and SAFO the maximum levels were 20 percent with DfDPOo IV 60 and 30 percent with DfDPOo IV 65. At 10 degree C all blends containing 20 percent palm olein except DfPOo IV 60 -SFO and SAFO 20:80 remained clear for about 180 days. At 5 degree C blends containing 10 percent palm olein and 90 percent SFO remained clear for 90 days. Blends of either SFO and SAFO with up to 20 percent DfPOo IV 60 or 30 percent 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
