Abstract:
1. A blending and fractionation process for obtaining an oil composition, the process including the steps of: (a) blending a palm stearin with an unsaturated oil having an oleic content of more than 20% and linoleic and linolenic contents of more than 30% in a predetermined ratio to form a mixture; (b) heating the mixture at a temperature of between 50° C. to about 65° C. until all crystals are melted; (c) fractionating the mixture obtained from step (b) at temperatures of 20° C., 10° C. and 8° C. successively to provide fractions in order to produce nucleation and obtain a mixture of oil and crystals wherein the crystals are of a suitable size and shape which permit efficient separation of the oil and crystals; and (d) separating the mixture of oil and crystals from the fractions to obtain the oil composition, wherein said oil composition contains saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids in a ratio of about 0.5 to 1.0:1.0:0.3 to 1.2.
