Method of forming a palm-based fractionated oil and fat, oil and fat composition and food product containing the same

Abstract

An oil and fat composition is provided having superior operability and processability, in terms of a liquefying phenomenon of sugar, tackiness and texture of fried doughnuts, filling condition and hardness of shortening, and solidifying time of coating chocolate, by the superior crystallization-promoting effect. A palm-based fractionated oil and fat has 70-90% by weight of the tripalmitin content to triglyceride and 1-8% by weight of the unsaturated fatty acid content to total fatty acid. The oil and fat includes a hard part obtained by, for example, performing a crystallization operation of palm super stearin with iodine value 10-17 so that the slurry SFC is 20% or less, and fractionating the slurry so that the hard part yield is 26% by weight or less. The fractionation is preferably performed so that a numerical value of the hard part yield/the slurry SFC is 10 or less.

What is claimed: 
     
         1 . A method for producing a palm-based fractionated oil and fat consisting of the steps of:
 performing a crystallization operation of a palm fractionated hard part to obtain a slurry; and   fractionating the slurry so that the hard part yield is 26% by weight or less to obtain the palm-based fractionated oil and fat wherein the tripalmitin content to triglyceride is 70-90% by weight, the unsaturated fatty acid content to total fatty acid is 1-8% by weight and the tripalmitin content to tri-saturated fatty acid triglyceride is 84-95% by weight.   
     
     
         2 . The method of  claim 1 , wherein the triglyceride containing unsaturated fatty acid content to triglyceride is 0.5-18% by weight in the palm-based fractionated oil and fat. 
     
     
         3 . The method of  claim 1 , wherein the palm fractionated hard part is palm super stearin with iodine value 10-17. 
     
     
         4 . The method of  claim 1 , wherein the crystallization operation of the fractionation is performed so that the slurry SFC is 20% by weight or less. 
     
     
         5 . The method of  claim 1 , wherein the crystallization operation is performed so that the slurry SFC is 20% by weight or less.
