PROBLEM TO BE SOLVED: To provide a method for producing a plastic oil-and-fat composition, exhibiting a sufficient hardness, good plasticity and heat resistant shape-holding property at normal temperatures (10 to 30°C) even in the case of without substantially containing a trans-fatty acid and also having a low saturated fatty acid ratio in its constituting fatty acid composition, and to provide a plastic oil-and-fat composition produced by the above method. SOLUTION: The method for producing the plastic oil-and-fat composition by using a hermetically closed type continuous process scraping tube type cooling machine comprises adding an oil-and-fat composition 2 having a lower melting point of its oil phase than that of an oil-and-fat composition 1 in a molten state to the oil-and-fat composition 1 in a state of still having flowability on completing plasticization by cooling, mixing and further cooling, and a plastic oil-and-fat composition prepared by the above method is also provided.
