Despite being an ultra-low oil content of 5 to 15% by weight of fats and oils, high emulsification stability, whipping properties, foaming properties with overrun of 50 to 200%, shape retention after whipping, mouth meltability, flavor It is to provide an excellent ultra-low oil-in-water emulsion. Furthermore, the present invention provides a low oil-in-water oil-in-water emulsion containing milk fat, wherein the ultra-low oil-in-water oil-in-water emulsion is mixed with a milk fat-containing emulsion. It is an oil-in-water emulsion containing fats and oils, and the weight ratio of (stearic acid) ÷ (oleic acid) is 1 or less, lauric acid is 40% by weight or more in fats and oils, and saturated fatty acids are fats and oils. It is an ultra-low oil content oil-in-water emulsion having an oil content of 5 to 15% by weight, characterized in that it contains 70% by weight or more, and a milk fat-containing emulsion is mixed with the ultra-low oil content oil-in-water emulsion. A low oil-in-water emulsion containing milk fat.油脂分５～１５重量％の超低油分であるにもかかわらず、高い乳化安定性、ホイップ性、オーバーランが５０～２００％の起泡性、ホイップ後の保形性、口溶け性、風味に優れた超低油分水中油型乳化物を提供することにある。さらに当該超低油分水中油型乳化物に乳脂含有乳化物を混合してなる、乳脂を含む低油分水中油型乳化物を提供すること。油脂及び水を含む水中油型乳化物であって、油脂の全構成脂肪酸において（ステアリン酸）÷（オレイン酸）の重量比が１以下、ラウリン酸が油脂中４０重量％以上、飽和脂肪酸を油脂中７０重量％以上含有することを特徴とする、油脂含量が５～１５重量％である超低油分水中油型乳化物であり、当該超低油分水中油型乳化物に乳脂含有乳化物を混合してなる、乳脂を含む低油分水中油型乳化物である。
