PURPOSE:To provide the subject oil and fat composition containing oil and fat having a specific physical property and capable of stably keeping the quality over a long period without using a stabilizer and a thickener. CONSTITUTION:The objective oil and fat composition can be produced by (1) adding an oily emulsifier (e.g., glycerol fatty acid ester) to 20-35% (preferably 25-35%) of oil and fat having the following physical properties (SFC(solid fat content), >=50% at 5 deg.C and 30-40% at 15 deg.C; melting point, 25-40 deg.C (measured under temperature increase); content of laurin-type oil and fat in the used oil and fat, 25-45%; particle diameter of the oil and fat, <=2mum) and converting the mixture to oily phase by heating, dissolution, etc., (2) separately preparing an aqueous phase e.g., by adding skim milk powder and sodium hexametaphosphate to a specific amount of water and heating and dissolving the mixture, (3) adding the oily phase to the aqueous phase and mixing to form an O/W-type emulsion and (4) keeping the emulsion at 70 deg.C and homogenizing with a high-pressure homogenizer, etc. |
