PROBLEM TO BE SOLVED: To provide an acidic oil-in-water emulsified composition which has, in addition to low-temperature resistance, high stability to the pressure shear and temperature change repeatedly generated during use, and contains diacylglycerol at a high concentration.SOLUTION: The acidic oil-in-water type emulsified composition contains the following (A), (B), and (C): (A) oil-and-fat containing 20 mass% or more of diacylglycerol, in which 80 mass% or more of a fatty acid that composes the diacylglycerol is an unsaturated fatty acid (B) polyglycerol fatty acid ester, in which 50 mass% or more of fatty acid that composes the polyglycerol fatty acid ester is a saturated fatty acid of carbon number 14-18, and an average polymerization degree of a glycerol is 20 or more and (C) yolk.COPYRIGHT: (C)2012,JPO&INPIT【課題】低温耐性に加え、使用時に繰り返し発生する加圧シェアと温度変化に対し、高度な安定性を有する、ジアシルグリセロールを高濃度で含有する酸性水中油型乳化組成物の提供。【解決手段】次の(A)、(B)及び(C):(A)ジアシルグリセロール含量が20質量%以上であり、かつジアシルグリセロールを構成する脂肪酸の80質量%以上が不飽和脂肪酸である油脂(B)ポリグリセリン脂肪酸エステルを構成する脂肪酸のうち、炭素数14~18の飽和脂肪酸が50質量%以上であり、かつグリセリンの平均重合度が20以上であるポリグリセリン脂肪酸エステル(C)卵黄を含有する酸性水中油型乳化組成物。【選択図】なし
