But, this method only filters through natural sedimentation, and oil product acid number is high, and gastronomical process oil smoke is big, and edible flavor is poor, and oil yield is low, and cake Residual oil is high. Also have and adopt water substitution, make cell rupture, moisture be impregnated into inside intact cell by soaking, make gelinite expand, add and propagandize seed hotly, making intracellular oil body flow out, separated by oil through succusion, this method is without squeezing, without solvent, oil body is made to flow out complete, and special fragrance can be produced, but extraction efficiency is inadequate, and whole process time is longer. Also have and adopt extract by solvents, but owing to the solvent of solubilized oils and fats mostly is toxic organic solvent, thus the Silybum Marianum Gaertn Seed Oil that this method extracts is typically used as iundustrial oil, and cannot eat. Recently also developing carbon dioxide supercritical fluid extraction, aqueous enzymatic method extraction etc. method, separation efficiency is high, but still exists or cost height enterprise or time longer etc. shortcoming.
Therefore, the drawbacks described above existed for the method preparing Silybum Marianum Gaertn Seed Oil in prior art and deficiency, the preparation method that it is an object of the invention to provide a kind of new Silybum Marianum Gaertn Seed Oil, separation efficiency is high, and excellent product quality, is suitable to industrialized production.
Summary of the invention
The invention provides a kind of preparation method extracting high-purity Silybum Marianum Gaertn Seed Oil from silybum marianum seed, comprise the following steps:
(1) screening: take Herba Silybi mariani seed raw material, sends into screening machine, removes the impurity in raw material, such as earth, sandstone, weeds seed, ghost and dust etc.;
(2) infiltration: the silybum marianum seed after screening of weighing, adds 5-10 times amount water and makes it be immersed in water, be simultaneously introduced 1-5 weight % tea polyphenols, be warming up to 40-60 DEG C, and stirring makes it fully infiltrate, and crosses elimination excessive moisture, the silybum marianum seed that must infiltrate; Infiltration degree is that the water content making silybum marianum seed reaches more than 30%, it is preferable that 30-35%;
(3) frozen dried: the silybum marianum seed of infiltration is proceeded to freeze-drier, is cooled to subzero 5-10 DEG C, maintains 10-15 minute, then temperature is adjusted to room temperature maintenance 10-15 minute, then is cooled to subzero 5-10 DEG C, maintains 5-10 minute, is taken out by silybum marianum seed raw material;
(4) ultrasonic Treatment: the material after lyophilised process proceeds to ultrasonic extractor, adds water and the 3-5% Silybum Marianum Gaertn Seed Oil of 0.5-1 times of weight, collaborative extraction 10-20 minute, ultrasonic power 250-350w;
(5) centrifugation: the solution after process is put in high speed centrifuge and is centrifuged 20 minutes, obtain Silybum Marianum Gaertn Seed Oil crude product;
(6) refine: add hargil and the 2-3 weight % tea polyphenols of oil weight 3-6%, temperature is increased to 80-100 degree, vacuum is maintained at about 96kPa, maintain 20-30 minute, through flame filter press elimination hargil, enter odor removing pot deodorize, temperature 200-240 DEG C, 1-2 hour time, the straying quatity of live (open) steam with do not cause oils and fats splash be advisable;
(7) oil is put into cooler and is cooled to room temperature, filter, pump into product tank.
Present invention also offers the Silybum Marianum Gaertn Seed Oil that said method prepares.
