METHOD FOR PRODUCING MONOGLYCERIDE-CONTAINING COMPOSITION

摘要

Provided is a method for producing a composition containing a monoglyceride of which the constituent fatty acid is a tall oil fatty acid and of which the crystallization at a lower temperature is further reduced. A method for producing a composition containing a monoglyceride of which the constituent fatty acid is a tall oil fatty acid, said method comprising the following steps (1) and (2): (1) performing an esterification reaction of glycerin with the tall oil fatty acid in such a manner that the molar number ratio [FA/GLY] of the molar number of a glycerin group to the molar number of a fatty acid group can fall within the range from 0.1 to 2.0, and then collecting unreacted glycerin; and (2) performing an esterification reaction of glycerin including glycerin collected in step (1) with the tall oil fatty acid.
