The present invention relates to a fat-soluble nutrient microcapsule and a method for producing the same, wherein the fat-soluble nutrient microcapsule contains 0.2-51.6% by weight of fat-soluble nutrient, 0.2-5.0% by weight of an antioxidant. It was first added with a fat-soluble nutrient consisting of 41.4-97.6% by weight of wall material and 2.0-5.0% by weight of water and retaining activity in the fat-soluble nutrient microcapsules. The ratio to fat-soluble nutrients is 0.990-0.997: 1. The method for producing the fat-soluble nutrient microcapsules includes an emulsification and a particle production step, in which emulsification is performed in a cavitation emulsifier, and by using this production method, the loss of the nutrient active substance of the fat-soluble nutrient microcapsules is reduced. It is highly stable as well as reduced.本発明は脂溶性栄養素マイクロカプセル及びその製造方法に関し、該脂溶性栄養素マイクロカプセルが、０．２－５１．６重量％の脂溶性栄養素、０．２－５．０重量％の抗酸化剤、４１．４－９７．６重量％の壁材、及び２．０－５．０重量％の水分からなり、前記脂溶性栄養素マイクロカプセル中の活性を保持している脂溶性栄養素と最初に添加した脂溶性栄養素との比率が０．９９０－０．９９７：１である。該脂溶性栄養素マイクロカプセルの製造方法は、乳化及び粒子製造工程を含み、そのうち、乳化はキャビテーション乳化機内で行なわれ、この製造方法を用いることにより、脂溶性栄養素マイクロカプセルの栄養素活性物質の損失を減少させると共に、安定性が高い。
