The present invention discloses reduced coenzyme Q10 powder, its composition and production method, wherein the reduced coenzyme Q10 powder is reacted with oxidized coenzyme Q10 in the presence of a reducing agent, and the organic in the reaction solution after completion of the reaction. After removing the solvent and other impurities, oil-soluble reduced coenzyme Q10 liquid was obtained, and then the obtained reduced coenzyme Q10 oil was directly cold spray molded to obtain reduced coenzyme Q10 powder. Reduced coenzyme Q10 powder has a reduced crystallinity, and in the X diffraction spectrum of Cu-Kα radiation, it has a strong peak at a diffraction angle 2θ of 18.9 °, particularly at 22.8 °. Has a strong absorption peak. The reduced coenzyme Q10 powder obtained by the present invention is in an incomplete crystal state, has good stability, excellent oral bioavailability, and is applied to health foods, cosmetics or drugs.本発明は還元型コエンザイムＱ１０粉末、その組成物及び製造方法を開示し、前記還元型コエンザイムＱ１０粉末は、酸化型コエンザイムＱ１０を還元剤が存在する場合で反応させ、反応完了後の反応液における有機溶剤及び他の不純物を除去してから油溶性還元型コエンザイムＱ１０液体を得、次に得られた還元型コエンザイムＱ１０油状物を直接にコールドスプレー成形して還元型コエンザイムＱ１０粉末を得、得られた還元型コエンザイムＱ１０粉末は、結晶化度が低下し、Ｃｕ－Ｋα放射線のＸ回折スペクトルでは、回折角２θが１８．９°であるところに強いピークを有し、２２．８°のところに特に強い吸収ピークを有する。本発明によって得られた還元型コエンザイムＱ１０粉末は不完全な結晶状態にあり、安定性が良好で、経口生物学的利用度が優れ、健康食品、化粧品又は薬物等に適用する。
