PROBLEM TO BE SOLVED: To provide a method of manufacturing an oily component-containing microcapsule which is a method of encapsulating an oily component insoluble in a polysaccharide aqueous solution or a gelating agent aqueous solution by a gelated polysaccharide thin film in which the content of the oily component in the capsule is made uniform.SOLUTION: The method of manufacturing the oily component-containing microcapsule includes: a step of dispersing the gelating agent aqueous solution in the oily component to prepare a (W/O) primary dispersion system a step of dispersing the (W/O) dispersion system in the saccharide aqueous solution to prepare a (W/O) secondary dispersion system and a step of forming a gelated polysaccharide thin film on the surface of droplets of the oily component while keeping the (W/O) secondary dispersion system.COPYRIGHT: (C)2011,JPO&INPIT【課題】多糖類水溶液やゲル化剤水溶液に溶解しない油性成分をゲル化多糖類薄膜によりカプセル化する方法において、カプセル中の油性成分の含有率を均一にすることのできる、油性成分含有マイクロカプセルの製造方法を提供する。【解決手段】ゲル化剤水溶液を油性成分中に分散させて(W/O)一次分散系を調製する工程と、この(W/O)一次分散系を多糖類水溶液中に分散させて(W/O)/W二次分散系を調製する工程と、この(W/O)/W二次分散系を維持して油性成分の液滴表面にゲル化多糖類薄膜を形成させる工程とを備えた。【選択図】図2
