Concentrating the Coicis semen filtrate by concentrating and drying, controlling reverse osmosis concentration temperature at 30 deg.C, and concentrating the filtrate to 11% to obtain Coicis semen concentrate. And (3) performing high-temperature instantaneous sterilization, namely placing the coix seed concentrated solution at the temperature of 137-139 ℃, performing sterilization for 31 seconds, and performing spray drying after sterilization to obtain the coix seed extract.
3 groups of extracts of coix seed were provided according to the above examples 1-3 for testing and tracking with the following parameters:
