Embodiment 1
[0023] 10 tons of milk thistle seeds are sent to the screening machine to remove impurities in the raw materials to obtain 9.95 tons of milk thistle seeds, add 10 times the amount of water to soak them in water, add 5% by weight of tea polyphenols at the same time, and heat up to 40- 60°C, stir to make it fully infiltrate, infiltrate until the water content reaches 35%, filter to remove excess water, and obtain infiltrated milk thistle seeds; transfer the infiltrated milk thistle seeds to freeze-drying equipment, and cool down to minus 5- 10°C, maintain for 15 minutes, then adjust the temperature to room temperature and maintain for 10-15 minutes, then lower the temperature to minus 5-10°C, maintain for 10 minutes, transfer the freeze-dried material to an ultrasonic extractor, and add an equal amount of water And 5% milk thistle oil, extract 15 minutes synergistically, ultrasonic power 350w; The solution after treatment is put into high-speed centrifuge and centrifuges 20 minut...
