Abstract

The present invention addresses the problem of providing a crystallization method having excellent separation performance between a crystal fraction and a liquid fraction after crystallization in a dry-mode separation method employing stirring crystallization and compression filtration, whereby it becomes possible to produce an SUS-rich oil/fat from an SUS-containing oil/fat. In the dry-mode oil/fat separation for producing an SUS-rich oil/fat having an SUS content of 60% by weight or more from an SUS-containing oil/fat having an SUS content of 30% by weight or more, a crystalline S3 component is added to the SUS-containing oil/fat in an amount of 5 to 200 ppm by weight relative to the amount of the SUS-containing oil/fat at a temperature that is higher by 0 to 2° C. than a cloud point of the SUS-containing oil/fat so as to be mixed, and performing stirring crystallization.
