PROBLEM TO BE SOLVED: To provide a powdered fat composition having superior dispersibility in water, a method of manufacturing the same, and a method of improving the functionality of an O/W type emulsified product.SOLUTION: Provided is a powdered fat composition consisting of an amphipathic substance capable of autonomously forming a closed vesicle in a water system or a sugar polymer capable of forming a particle of the sugar polymer, a fat component, and an excipient. When mixed with water, an O/W type emulsified product is formed by the action of the closed vesicle or the particle of the sugar polymer. It is desirable that the amphipathic substance or the sugar polymer is contained in an amount sufficient to maintain an emulsified state of an oil droplet derived from the fat component.COPYRIGHT: (C)2013,JPO&INPIT【課題】水への分散性に優れる粉末油脂組成物及びその製造方法、並びにO/W型乳化物の官能性の改善方法を提供すること。【解決手段】粉末油脂組成物は、水系において自発的に閉鎖小胞体を形成する両親媒性物質又は糖ポリマーの粒子を形成する糖ポリマーと、油脂成分と、賦形剤とを含んで構成され、水と混和された際、前記閉鎖小胞体又は前記糖ポリマーの粒子の作用でO/W型乳化物を形成するものである。油脂成分に由来する油滴の乳化状態を維持させる量の両親媒性物質又は糖ポリマーが含まれていることが好ましい。【選択図】図1
