Purpose of this invention, is the powder oil and fat constituent and its production manner, and offers the functionality improvement manner of O/W die emulsification ones to be superior in detachability to the water. The occasion where the powder oil and fat constituent is formed, is mixed including with the sugar polymer and the oil and fat component and the forma medicine which form the parents crocking Characteristic material or the grain of the sugar polymer which forms closed small cell voluntarily in water system, the water, it is something which forms O/W die emulsification ones in aforementioned closed small cell or the operation of the grain of the aforementioned sugar polymer. It is desirable for the parents crocking Characteristic material or the sugar polymer of the tonnage which makes the emulsification state of the oil droplet maintain which is derived from the oil and fat component to be included.本発明の目的は、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である。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。
