Abstract
Provided is a preparation process of a diglyceride-rich fat or oil, which includes bringing a fat or oil containing diglycerides in an amount of 50 mass % or greater and having a transition metal content of 5 ppm or less into contact with steam while forming a thin film of the fat or oil. This process makes it possible to prepare a diglyceride-rich fat or oil having a reduced odor and good color efficiently.
