Abstract: The invention relates to the technical field of natural product preparation, and specifically to low-odor water-soluble copper chlorophyllin and a preparation method and use thereof. In the invention, a copper chlorophyllin paste is used as a raw material and is subjected to deodorization treatment, colloidal solution emulsification treatment, and secondary microencapsulation and drying treatment, and saponification with a strong base such as sodium hydroxide is not used. Therefore, the process route is safer and simpler. The obtained low-odor water-soluble copper chlorophyllin has good water solubility, is not easy to precipitate in a solution with a pH of 2 to 4.0, has good stability and low odor, and is not easy to “bleed” when used in jelly and jam products.

Abstract: 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.

Abstract: Please replace the following substitute abstract for the abstract currently on file: A method for preparing a water-soluble rutin powder includes: heating and mixing a plant polysaccharide substance, a filler, and water to obtain a wall material solution; adding an antioxidant and a rutin powder into the wall material solution at a first temperature, followed by emulsification and dispersion, pH adjustment, and high-pressure homogenization to obtain a rutin powder emulsion; and carrying out heating fusion of the rutin powder emulsion to obtain a water-soluble rutin powder. With the preparation method, a water-soluble rutin product is obtained through emulsification, high-pressure homogenization, ultra-high-temperature fusion, drying and other processes by using modified starch and a plant polysaccharide as a wall material and rutin as a core material.
