Provided is a production method which can produce, with a high yield, a fat or oil composition containing a diacylglycerol at a high content and having a favorable external appearance at room temperature. Specifically, provided is a production method for a refined fat or oil composition, comprising the following steps (1) and (2) : (1) a step of adding a polyglycerin fatty acid ester having an average polymerization degree of glycerin being 20 or more to a fat or oil composition containing 50 mass% or more of diacylglycerol, followed by cooling and (2) a step of separating a crystal precipitated in the step (1) from a liquid portion.本發明提供一種可產率良好地製造常溫下之外觀良好之二醯甘油含量較高之油脂組合物的方法。本發明之純化油脂組合物之製造方法包括以下步驟(1)及(2):(1)於含有二醯甘油50質量%以上之油脂組合物中添加甘油之平均聚合度為20以上之聚甘油脂肪酸酯,繼而進行冷卻的步驟;(2)將藉由上述步驟而析出之結晶自液體部分離的步驟。
