Problems solved by technology

[0003] At present, the soybean oil preparation process mainly includes pressing method and extraction method. To a certain extent, the strong aroma of crude oil is retained, but the oil produced has more impurities and a lower oil yield; while the leaching method uses the principle of solid-liquid extraction, spraying and soaking the oil with food-grade solvents, from The method of extracting oil from oil plants. The technological process is cleaning, crushing, softening, flaking, leaching, evaporation, steam stripping, soybean crude oil, refining, and soybean oil. It has the advantages of high oil yield and low production cost. , but in the existing leaching method, the leaching agent will remain in the crude oil during the leaching process, resulting in poor quality of the crude oil and seriously affecting the production quality of soybean oil

Abstract

The invention discloses a preparation method of soybean oil, which comprises the following steps of: firstly, sequentially carrying out magnetic impurity removal, winnowing and washing on soybeans toobtain qualified soybeans; secondly, carrying out drying processing on the qualified soybeans, until moisture content of the soybeans is 12% to 15%; then grinding the dried soybeans to obtain soybeanmeal; mixing the soybean meal, radix polygoni multiflori, roxburgh rose powder and ethyl alcohol and carrying out ultrasonic extraction to prepare soybean crude oil; finally, after carrying out hydrated degumming on the obtained soybean crude oil, carrying out freezing crystallization and grain growing, and then filtering to obtain a soybean oil finished product. The soybean oil prepared by the preparation method is high in quality, comprises few impurities and is high in oil yield; meanwhile, according to the invention, the soybean meal is mixed with medicinal materials of the radix polygonimultiflori and the roxburgh rose powder, so that beneficial substances in the radix polygoni multiflori and the roxburgh rose powder are naturally blended into the soybean oil, and thus, not only is the soybean oil enabled to have a better health conditioning effect, but also the fragrance of the soybean oil can be improved and the soybean oil have effects of replenishing vital essence and blood,strengthening the bones and muscles, nourishing liver and kidney and promoting digestion.

Description

technical field [0001] The invention relates to the technical field of vegetable oil processing, 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. Soybean oil is rich in linoleic acid, which is an essential fatty acid for the human body and has important physiological functions, and linoleic acid has the effect of preventing cardiovascular diseases and can reduce serum cholesterol levels. Among them, the lack of linoleic acid in young children will not only dry the skin and thicken the scales, but also slow down growth and development; the lack of linoleic acid in the elderly will cause cataracts and cardiovascular and cerebrovascular diseases. At the same time, soybean oil also contains a large amount of vitamin E, vitamin D and rich lecithin, which are very benefic...
