<P>PROBLEM TO BE SOLVED: To provide a stable solid-fat microcapsule in which a useful substance is encapsulated at a high rate and the particle diameter of which is regulated, causing no leakage of the useful substance during preservation. <P>SOLUTION: The solid-fat microcapsule has such a structure that a water soluble substance is enclosed with solid fat. In the microcapsule, a prepared W/O/W emulsion is dehydrated using a monodispersed solid fat microcapsule whose average particle diameter is 0.1-100μm, cumulative volume distribution of 10% diameter is half or more based on that of 50% diameter, and in which the particle diameter distribution of 90% diameter is ≤1.5 times as large as that of 50% diameter or less. <P>COPYRIGHT: (C)2004,JPO |
