There is provided a coenzyme Q10-containingcomposition having a high coenzyme Q10 content and excellentstability and bioavailability of coenzyme Q10, without usingsynthetic emulsifiers such as glycerin fatty acid esters,polyglycerin fatty acid esters, organic acid monoglyceridesor sucrose fatty acid esters.The coenzyme Q10-containing liquid composition isobtained by dispersing and emulsifying coenzyme Q10 in anaqueous liquid containing a water-soluble substanceconsisting of octenylsuccinate starch and dextrin, andglycerin. The liquid composition may be dried to prepare acoenzyme Q10-containing solid composition.
