The present invention relates to a process for preparing a hard butter, which comprises conducting transesterification between one or more selected from the group consisting of straight-chain saturated C16-22 fatty acids and lower alcohol esters thereof and a triglyceride having oleoyl group and/or linoleoyl group at the 2-position with an action of a granulated powder lipase comprising a lipase derived fromand/orand a soybean powder, and removing the granulated powder lipase after the transesterification. The process is industrially suitable process for preparing a hard butter, which have excellent properties as a cacao butter equivalent.

Process for preparing hard butter

The present invention discloses a method of producing triglycerides rich in XOX fat and/or XLX fat, which comprises the steps of heating and dissolving triglycerides (XOX fat and/or XLX fat) which comprise 20 to 60 mass % of a triglyceride having a saturated fatty acid residue on each of the first and third position and an oleoyl group and/or a linoleoyl group on the second position in total triglycerides in the presence of 1 to 30 mass % of a fatty acid lower alkyl ester; and then cooling the mixture to precipitate crystals and conducting solid-liquid separation. This method is a more efficient and industrially suitable fractionation and production method of fats and oils which are rich in a triglyceride (XOX fat and/or XLX fat) having a saturated fatty acid residue on each of the first and third position and an oleoyl group and/or a linoleoyl group on the second position.
