<P>PROBLEM TO BE SOLVED: To provide a method for producing oil and fat containing oil and fat having a high melting point of 50°C or higher in a starting material and performing 1,3-position specific transesterification by an enzyme, capable of keeping the isomerization rate the fatty acid composition at the 2-position low even by using an inexpensive enzyme, and also having a short production time. <P>SOLUTION: This method for producing the oils and fats includes (1) a step for preparing (A) the oils and fats having a melting point of 50°C or higher, and (2) a step of performing the 1,3-position specific enzymatic transesterification by using (B) oils and fats having triglyceride in which 40 wt.% or more of the amount of the contained saturated fatty acid is bonded at the 2-position and (A) the oils and fats, or by using (C) oils and fats having triglyceride in which 40 wt.% or more of the amount of the contained unsaturated fatty acid is bonded at the 2-position and (A) the oils and fats, and in the step (1), (a) oils and fats having a melting point of 50°C or more is contained as the starting raw material. <P>COPYRIGHT: (C)2009,JPO&INPIT |
