A method of preparing water-soluble lutein ester microcapsules includes: mixing marigold flower particles with an extracting solvent, refluxing at 65-85&#xb0; C.; removing the extracting solvent to obtain a crude extract; washing the crude extract with a washing solvent; removing the washing solvent to obtain a crude lutein ester; adding an oil-phase antioxidant and a vegetable oil to the crude lutein ester, mixing and heating at 90-100&#xb0; C. to obtain a lutein ester oil phase; adding a wall material, an emulsifier, a water-phase antioxidant, and a water-phase filler into water, and heating to obtain a water phase; adding the lutein ester oil phase to the water phase under a high-speed shearing, mixing evenly, and homogenizing to obtain a lutein ester emulsion; drying twice to obtain semi-finished lutein ester microcapsules; and solidifying to obtain the lutein ester microcapsules. Water-soluble lutein ester microcapsules prepared by the method are also disclosed.

A method for preparing a water-soluble curcumin mixture with high bioavailability includes the following steps: A) dissolving curcumin, vitamin C and ascorbyl palmitate in an ethanol aqueous solution, evaporating ethanol under reduced pressure, and vacuum drying to obtain a curcumin-vitamin C-ascorbyl palmitate co-crystal; B) high-speed emulsifying the curcumin-vitamin C-ascorbyl palmitate co-crystal and a wall material colloidal solution under vacuum, sequentially conducting a two-stage wet grinding, a homogenization and a potential adjustment to obtain an emulsified body; and C) subjecting the emulsified body to microencapsulation with a wall material twice and drying to obtain the water-soluble curcumin.
