Embodiment 1

[0023] A preparation method of soybean oil, comprising the following steps:

[0024] (1) Soybean pretreatment: Soybeans are successively air-selected, dried and pulverized to obtain soybean powder. Said air-selection is to add soybeans to a suction flat sieve to remove impurities such as metals, stones and dust in soybeans; The drying is to send the soybeans into a microwave oscillator, and dry them until the moisture content of the soybeans is 10% under the condition of a microwave power of 650W; the crushing is to send the dried soybeans into a grinder and grind them to fineness 20 mesh;

[0025] (2) Soybean crude oil production: mix soybean powder, Rosa roxburghii, green tea and organic solvent, adjust the liquid-solid ratio to be 8:1, then send it into a reflux extractor equipped with an ultrasonic oscillator, in an ultrasonic power of 600w Under the action of ultrasonic waves, heat and reflux extraction twice, each extraction time is 10min, then carry out suction filtrat...

Embodiment 2

[0028] A preparation method of soybean oil, comprising the following steps:

[0029] (1) Soybean pretreatment: Soybeans are successively air-selected, dried and pulverized to obtain soybean powder. Said air-selection is to add soybeans to a suction flat sieve to remove impurities such as metals, stones and dust in soybeans; The drying is to send the soybeans into a microwave oscillator, and dry them until the moisture content of the soybeans is 12% under the condition of a microwave power of 750W; the crushing is to send the dried soybeans into a grinder and grind them to fineness 30 mesh;

[0030] (2) Soybean crude oil production: mix soybean powder, Rosa roxburghii, green tea and organic solvent, adjust the liquid-solid ratio to be 10:1, then send it into a reflux extractor equipped with an ultrasonic oscillator, in an ultrasonic power of 800w Under the action of ultrasonic waves, heat and reflux extraction 4 times, each extraction time is 15min, then carry out suction filt...

Abstract

The invention discloses a soybean oil making method and belongs to the technical field of vegetable oil making. The method includes sequentially conducting windowing, drying and breaking on soybeans, then mixing and conducting ultrasonic extraction on soybean powder, roxburgh rose, green tea and organic solvent, conducting hydrated degumming on the obtained soybean crude oil, then conducting freezing crystallization and growing the grain, and finally conducting filtering to obtain a finished product of soybean oil. By mixing and extracting the soybean powder, the roxburgh rose and the green tea, beneficial substances in the green tea and the roxburgh rose can be melt into soybean oil naturally, the soybean oil achieves a healthy opsonic effect, the fragrance of the soybean oil is increased, and the fragrance of the green tea and the roxburgh rose is still reserved in the soybean oil.

Description

technical field [0001] The invention relates to the technical field of vegetable oil preparation, in particular to a method for preparing soybean oil. Background technique [0002] Soybean oil is a kind of oil extracted from soybean seeds. Soybean oil is light yellow, clear and transparent, and has no sediment. Good quality soybean oil is lighter in color. The fatty acid composition of soybean oil is better. It is rich in linoleic acid, which is an essential fatty acid for human body and has important physiological functions. Linoleic acid has a significant effect on preventing cardiovascular diseases, and can reduce serum cholesterol levels. Soybean oil contains a lot of vitamin E, vitamin D and rich lecithin, which are very beneficial to human health. The lack of linoleic acid in young children will not only cause dry skin and thickened scales, but also slow growth and development; the lack of linoleic acid in the elderly will cause cataracts and cardiovascular and cerebr...
