Clarity and chemical composition of palm olein-sunflower and palm olein-safflower oil blends. - (:unkn) unknown (My University)
Double fractionated palm oilein samples of iodine value (IV) 609 (DfPOo IV60) and IV65 (DfPOo IV65) 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 IV65 that could be mixed with SFO and SAFO to give blends that remained clear for at least 240 days at 20C were 60 and 70% respectively. With DfPOo IV60, the levels were 30% and 60% respectively. At 15C, with both SFO and SAFO the maximum levels were 20% with DfPOo IV60 and 30% with DfPOo IV65. At 10C, all blends containing 20% palm oein except DFPOo IV60 SFO and SAFO 20:80 remained clear for about 180 days. At 5C, blends containing 10% palm oein and 90% SFO ramined clear for 90 days. Blends of either SFO or SAFO with, up to 20% DfPOo IV60 or 30% DfPOo IV65 passed the cold test. Blending of SFO or SAFO with DfPOo improved the fatty acid composition interms of the saturated:monosaturated:polyunsaturated ratio.
