Infiltration degree is that the water content of silybum marianum seed is made to reach 30% or more, preferably 30-35%；
(3) frozen dried: being transferred to freeze-drier for the silybum marianum seed of infiltration, is cooled to subzero 5-10 DEG C, maintains 10-15 points
Clock, then adjust the temperature to room temperature and kept for 10-15 minutes, then be cooled to subzero 5-10 DEG C, it maintains 5-10 minutes, by silybum marianum seed original
Material takes out；
(4) ultrasonication: treated that material is transferred to ultrasonic extractor by freeze-dried, and the water of 0.5-1 times of weight is added
And 3-5% Silybum Marianum Gaertn Seed Oil, collaboration are extracted 10-20 minutes, ultrasonic power 250-350w；
(5) be centrifugated: will treated that solution is put into supercentrifuge is centrifuged 20 minutes, obtain Silybum Marianum Gaertn Seed Oil crude product；
(6) refine: the carclazyte and 2-3 weight % tea polyphenols of oil weight 3-6% is added, temperature is increased to 80-100 degree, and vacuum degree is protected
It holds in 96kPa or so, maintains 20-30 minutes, filter off carclazyte through flame filter press, enter odor removing pot and be deodorized, 200-240 DEG C of temperature,
Time 1-2 hour, the straying quatity of direct steam is not to cause grease splashing to be advisable；
