PROBLEM TO BE SOLVED: To provide microcapsules having a high content of a fat-soluble active substance and a desirable low content of free surface fat which can be used for, e.g., food and tablets containing an active substance; and a process for preparation thereof.SOLUTION: The invention relates to a microcapsule comprising 30 to 60% of at least one fat-soluble active substance selected from provitamins, vitamins and esters thereof, monounsaturated fatty acids, polyunsaturated fatty acids (PUFA's), carotenoids and benzoquinones, where the ratio between the fat-soluble active substance and the hydrocolloid is at least 5:1, and optionally comprising one or more other matrix components. The invention also relates to a process for preparing the microcapsule.【課題】活性物質を含む錠剤、食品等に使用できる、脂溶性活性物質の含有量が高くかつ遊離表面脂肪の含有量が望ましい低さであるマイクロカプセルおよびその調製方法の提供。【解決手段】プロビタミン、ビタミンおよびそれらのエステル、一価不飽和脂肪酸、多価不飽和脂肪酸(PUFA’s)、カロテノイド類ならびにベンゾキノン類から選択される少なくとも一種の脂溶性活性物質を30~60%含有し、脂溶性活性物質と親水コロイドの比が少なくとも5:1であり、他に任意の一種以上のマトリックス成分を含むマイクロカプセル、およびその調製方法。【選択図】なし
