A method for extracting oils from sauces while simultaneously determining fat content, peroxide value, and acid value is disclosed. The method is simple to operate and requires uncomplicated equipment. It features a short testing cycle and high efficiency, and suitable for the extraction of oils from oil-rich emulsified encapsulated sauces (such as salad dressings) with high extraction rates. The determination of peroxide value and acid value is not affected by pretreatment methods, ensuring more representative results. It addresses the challenges of difficult oil separation and extraction from oil-rich emulsified encapsulated sauces and solves significant issues encountered when using acid hydrolysis and alkaline hydrolysis methods to determine peroxide value and acid value. It enables the simultaneous monitoring of three physicochemical indicators (fat content, peroxide value, and acid value). This high-efficiency method is particularly suitable for tracking and monitoring during the production process, thereby enhancing production efficiency and reducing production costs.

A method for preparing a water-soluble curcumin liquid 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; and B) high-speed emulsifying the curcumin-vitamin C-ascorbyl palmitate co-crystal and a water-soluble colloidal solution that includes an emulsifying additive under vacuum, sequentially conducting a two-stage wet grinding, a homogenization and a potential adjustment to obtain the water-soluble curcumin liquid.

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.
