살균 등의 고온 공정을 거쳐도 유화 안정성을 유지하고 (내열성), 가열 전후에서의 입자경 분포의 변화가 작은 유화 조성물로서, 유상 성분이 상태 변화하는 경우에도 (예를 들어, 강온에 의해 유상 성분이 응고, 결정화됨. 승온에 의해 유상 성분이 융해됨.), 유화 안정성을 유지하고 (강온 내성), 제조시 취급이 용이한 조성물을 제공하는 것을 과제로 한다. 고체 입자, 알킬기를 1 개 갖는 계면 활성제, 유상 성분, 및 수상 성분을 갖고, 상기 유상 성분은, 불포화 결합 및/또는 산소 원자를 갖는 유상 성분을 포함하고, 상기 유상 성분과 상기 수상 성분의 계면에 상기 고체 입자가 존재하는, 수중유형 유화 조성물에 의해 과제를 해결한다. The object of the present invention is to provide an emulsion composition that maintains emulsion stability even after high temperature process such as sterilization (heat resistance), shows a small change in particle size distribution between before and after heating, and maintains emulsion stability even under conditions where transformation of an oil phase component (for example, solidification or crystallization of the oil phase component due to temperature drop, or melting of the oil phase component due to temperature rise) occurs (temperature drop resistance), wherein the composition is easily handled during the production process. The object is solved by an oil-in-water emulsion composition containing solid particles, a predefined surfactant, an oil phase component, and an aqueous phase component, wherein the oil phase component includes a predefined oil component and the solid particles are distributed along the interface between the oil phase component and the aqueous phase component.
