The fatty acid composition of the walnut oil is mainly linoleic acid 5413%, oleic acid 2013% and linolenic acid 1618%, wherein the linoleic acid and linolenic acid are essential fatty acids for human body, and the walnut oil has the effects of reducing blood fat, preventing coronary heart disease and atherosclerosis, improving learning memory and omentum reflex capacity, preventing senile dementia and cancer and the like. In addition, linoleic acid has the function of smoothing and smoothing the skin and is called as skin beautifying acid. Therefore, the strong-flavor refined walnut oil and the VA and VE multi-dimensional fortified walnut oil are developed by utilizing abundant walnut resources, a high-grade health edible oil is provided, the walnut industrialization process can be promoted, the regional economic development and farmer income increase are driven, and the method is an industrialization project with profound significance. Is high-grade edible cooking oil which is ideal in daily life of people, but no safe production technology of selenium-rich health walnut oil commodity is reported at present.
The walnut oil is vegetable oil which is prepared by squeezing walnut kernels serving as a raw material. Belongs to edible oil. The walnut oil is a high-grade edible oil, the oil content of the walnut kernel is up to 65-70%, and 25-30 kg of oil can be extracted from every 100kg of walnut kernels with shells. The grease content of the walnut reaches 65-70 percent, and the walnut oil belongs to all woody oil and is reputed as oil depots on trees. The essence of the walnut is extracted by a modern process, and the walnut oil is a new generation product of the walnut. The walnut oil is natural fruit oil juice which is prepared by selecting high-quality walnuts as raw materials and adopting an internationally advanced process. In the international market, the walnut oil is known as the oriental olive oil and is like the olive oil, so that the walnut oil is highly favored by consumers. The walnut oil is a high-grade health edible oil for children in development period, female in gestation period and postpartum recovery, and has the advantages of fresh and pure taste, rich nutrition, light mouthfeel, and similar fatty acid state to breast milk, and is easy to digest and absorb. According to analysis, the fat content of each 100 g of walnut kernels is 63-76 g. The main components of the fat are linoleic acid glyceride, linolenic acid and oleic acid glyceride, which are all fatty acids necessary for human body. The walnut oil is prepared by extracting walnut kernel oil, refining and purifying, has yellow or brown yellow color, and is an ideal high-grade edible cooking oil in daily life.

The third kind of aqueous extraction process is the production process of refined walnut oil, but the water is added into the walnut oil to hydrate and degum, so that nervonic acid, gadoleic acid, DHA, EPA, trace functional fatty acid, squalene, melatonin, flavone, nonadecanol, carotene and other trace functional components in the walnut oil are partially taken away, and the efficacy of the walnut oil is reduced; the rancidity oil in the walnut oil is removed, and the rancidity oil is saponified by adding sodium hydroxide to pollute the environment, so that linoleic acid and linolenic acid contained in the walnut oil can be generated into sodium linoleate and sodium linolenate, and the inherent health care of the linoleic acid and the linolenic acid is damaged; the clay is required to filter particulate impurities, and is required to be replaced frequently, so that the labor intensity is high; but also brings away a certain amount of walnut oil, which causes product loss; the production time is long, and the process is laggard; supercritical of the fourth kindCO2The extraction process has extremely high power consumption and high production cost, and a third type of aqueous extraction process is also adopted for producing the refined walnut oil; the process for extracting walnut oil by a microwave method is not mature temporarily.
In summary, the problems of the prior art are as follows:
(1) the method for preparing the walnut oil in the prior art comprises the following steps: fresh walnut kernels are peeled, dried and roasted, spirally squeezed, crude walnut oil and activated clay are filtered, hydrated and degummed, deacidified, dried, decolorized, vacuum deodorized, a compound antioxidant and a nutrition enhancer are added, and the mixture is mixed, cooled, filled and finished to obtain the refined walnut oil, wherein the production process of the walnut oil needs clay to filter particle impurities, needs to change clay frequently, and has high labor intensity; but also brings away a certain amount of walnut oil, which causes product loss; adding water into the oil for degumming, and taking away part of nervonic acid, gadoleic acid, DHA, EPA, trace functional fatty acid, squalene, melatonin, flavone, nonadecanol, carotene, etc. to reduce the effect of oleum Juglandis; the rancidity oil in the walnut oil is removed, and sodium hydroxide is added, so that linoleic acid and linolenic acid contained in the walnut oil are generated to form sodium linoleate and sodium linolenate, and the inherent health care of the linoleic acid and the linolenic acid is damaged.
(2) The edible oil produced by the naturally planted oil crops hardly contains selenium, and the traditional walnut oil does not produce organic selenium-rich functional walnut oil by using safe biological organic selenium and biological nano-selenium.
The difficulty of solving the technical problems is as follows:

Not only produces a product better than walnut oil refined by the traditional chemical method, but also overcomes the defects of walnut oil refined by the traditional chemical method. The production efficiency is greatly improved, the production cost is reduced, the environmental pollution is effectively prevented, and the equipment comprises the application of new material science, new equipment manufacturing technology and new technology to new equipment.
2. At present, the edible oil for naturally planted plants and the edible oil for cultured animals do not contain selenium because fat molecules do not have a group bond combined with selenium. And macromolecular safe biological organic selenium and large-particle-size biological nano selenium are not easy to be uniformly dissolved in the edible oil, the biological selenium edible oil can be produced only by blending the biological organic selenium dissolved in the oil by using extracted purified water and the biological nano selenium dissolved in the oil by using purified water, the biological organic selenium dissolved in the oil and the small-particle-size biological nano selenium dissolved in the oil are produced by producing the non-toxic safe biological organic selenium and the non-toxic safe biological nano selenium dissolved in the walnut oil according to the dosage of the organic selenium-rich walnut oil, and the technology is a leading high-tech technology at home and abroad.
