Embodiment 1

[0017] A method for finishing walnut oil, comprising the following steps:

[0018] (1) Walnut oil pressing: the walnut kernels are screened, crushed, cooked and pressed to obtain virgin walnut oil;

[0019] (2) Dehydration and dephosphorization: Pour the virgin walnut oil into the reaction kettle for dephosphorization reaction, promote the water absorption and swelling of the phospholipids in the walnut oil, and separate and precipitate, thereby reducing the phospholipids in the walnut oil. ℃ for 31 minutes, and then reacted for 23 minutes at a pressure of 0.74 MPa and a temperature of 81 ℃. After centrifugal filtration, the dephosphorized walnut oil was obtained. The water is collected and discharged through the condenser tube, and the dehydration time is 1.5 hours. The low-pressure heating method will quickly evaporate the water in the oil, reduce the water content in the oil, and obtain dehydrated and dephosphorized walnut oil;

[0020] (3) Dewaxing and degreasing: Add sod...

Embodiment 2

[0028] (1) Walnut oil pressing: the walnut kernels are screened, crushed, cooked and pressed to obtain virgin walnut oil;

[0029] (2) Dehydration and dephosphorization: Pour the virgin walnut oil into the reactor for dephosphorization reaction, promote the water absorption and swelling of the phospholipids in the walnut oil to separate and precipitate, thereby reducing the phospholipids in the walnut oil. ℃ for 34 minutes, and then reacted for 25 minutes at a pressure of 0.87 MPa and a temperature of 83 ℃. After centrifugal filtration, the dephosphorized walnut oil was obtained. The water is collected and discharged through the condenser, and the dehydration time is 2 hours. The low-pressure heating method will quickly evaporate the water in the oil, reduce the water content in the oil, and obtain dehydrated and dephosphorized walnut oil;

[0030] (3) Dewaxing and degreasing: Add sodium hydroxide solution to the dehydrated dephosphorized walnut oil in the reaction kettle, sti...

Abstract

The invention discloses a method for fine processing of walnut oil. The method is characterized in that the method comprises the steps of squeezing of walnut oil, wherein walnut kernels are screened, smashed, steamed and boiled and squeezed, and virgin walnut oil is prepared; dehydration and dephosphorization, wherein the walnut oil is poured into a reaction kettle to be subjected to dephosphorization reaction, the dephosphorized walnut oil is put into the reaction kettle and subjected to dehydration, and discharged moisture is collected through a condensation pipe; dewaxing and degreasing, wherein a sodium hydroxide solution is added into the dehydrated and dephosphorized walnut oil in the reaction kettle, stirred, mixed, and heated; decoloration, wherein activated clay is added into the dehydrated and dephosphorized walnut oil, subjected to ultrasonic wave vibration and mixing, and then subjected to magnetization treatment by using a magnetizer; fine filtration, wherein the decolorized walnut oil is put into a vacuum tank and subjected to heating refining, cooled and filtered by using a filter screen.

Description

technical field [0001] The invention belongs to the technical field of walnut deep processing, and in particular relates to a method for finishing walnut oil. Background technique [0002] Walnut oil is rich in protein, unsaturated fatty acid, linoleic acid, trace elements, phospholipids, yellow phosphorus, vitamins and other nutrients, among which the unsaturated fatty acid content is as high as 93%, and it is rich in linoleic acid and flax The oil component has a good preventive function on cardiovascular and cerebrovascular diseases, cancer and senile dementia. At present, the output of walnut oil in western developed countries has surpassed that of olive oil and has become the main edible oil variety; long-term consumption of walnut oil can improve the body's immunity , improve the microcirculation system and expand blood vessels, can effectively reduce cholesterol and blood sugar, and it also has the effects of regulating cholesterol, nourishing the brain, protecting th...
