Problems solved by technology

[0004] At present, the research on the production and preparation of milk thistle oil is still not deep enough. Generally, milk thistle seed is used as raw material, and it is made by direct cold pressing, filtration and other processes.
However, this method only undergoes natural sedimentation and filtration, and the acid value of the oil is high, the cooking process is heavy, the flavor is poor, and the oil yield is low, and the residual oil of the cake is high.
In addition, the water substitution method is used to rupture the cells by soaking, and the water penetrates into the interior of the intact cells to make the gel swell, heat and fry the seeds to make the oil in the cells fl...

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...

Embodiment 2

[0025] 2 tons of milk thistle seeds are sent to the screening machine to remove impurities in the raw materials to obtain 1.93 tons of milk thistle seeds, add 5 times the amount of water to soak them in water, add 3% by weight of tea polyphenols at the same time, and heat up to 40- Stir at 60°C to fully infiltrate until the water content reaches 32%, 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 4% milk thistle oil, extract 15 minutes synergistically, ultrasonic power 300w; The solution after treatment is put into high-speed centrifuge and centrifuges 20 minutes, obtains milk thi...

Abstract

The invention relates to a method for extracting silybum marianum oil from silybum marianum seeds. By adopting a method of immersing, freeze drying and ultrasonic extraction, the product yield is greatly increased; moreover, the content of unsaturated fatty acid in the oil product reaches more than 50 percent, the loss is basically avoided, and the yield reaches up to more than 95 percent; and moreover, the oil is clear in color, full in fragrance and very suitable for industrialized production. The product can be directly used as healthy edible oil or can be applied to a health product.

Description

technical field [0001] The invention relates to a method for extracting milk thistle oil, more particularly, to a method for extracting milk thistle oil from milk thistle seeds. Background technique [0002] Silybummarianum (Silybummarianum) is a plant native to Western Europe and North Africa. It has no strict requirements on soil and water. It can be planted on sandy land and saline-alkali land. It has strong adaptability. After being introduced to China, it has grown in Shaanxi, Gansu, Heilongjiang, Hebei and other provinces have a large area of ​​cultivation, mainly for the extraction of silymarin. Silymarin is known for its liver-protecting and choleretic effects, and is widely used in the prevention and treatment of cardiovascular and cerebrovascular diseases. However, besides silymarin, milk thistle seeds also contain a large amount of milk thistle oil. On April 16, 2014, the National Health and Family Planning Commission approved milk thistle seed oil as a new food ...
