Procedure

The stearin part of transesterified oil can be obtained by transesterifying a raw oil-and-fat containing 10 to 40% by mass of oleic acid, 10 to 40% by mass of stearic acid and 30 to 70% by mass of palmitic acid, and then fractionating it so as to obtain an olein part, and further fractionating the olein part. It is preferable to use a raw oil-and-fat containing 10 to 35% by mass of oleic acid, 15 to 40% by mass of stearic acid and 35 to 65% by mass of palmitic acid, and it is more preferable to use a raw oil-and-fat containing 10 to 30% by mass of oleic acid, 15 to 35% by mass of stearic acid and 35 to 55% by mass of palmitic acid.
