Problems solved by technology

Deacidification using conventional refining methods uses caustic soda for deacidification. In addition to neutralizing the free fatty acids in the oil, the alkali will also undergo saponification reactions with the oil, resulting in a low refining rate. After decolorization, high temperature deodorization is required. Long, (4 to 6 hours, 250 degrees) long time high temperature deodorization, walnut refined oil is easy to oxidize and become rancid

Embodiment 1

[0026] 3 tons of walnut oil oil, 5 acid prices, color Rowon 25.4 mm yellow 25, red 4, peroxide value 2.5.The hydrophobic tone is adjusted to 40 ° C. Under the rapid stirring, slowly add 0.2%of the consumption -grade phosphoric acid that weighs 0.2%. The concentration of phosphate is 85%. All phosphate is controlled in 20 minutes.After the temperature began, after the final temperature reached 60 ° C. After the hydration reaction was completed, the static settled for 8 hours, and then put the oil feet.Washing: Heat the oil with the above oil feet and heat up to 90 ° C, and wash the soft water at 95 ° C for watering. The amount of water is 8%of the oil weight. Stir quickly during the washing.Wash 2 times.

[0027] Add the pecan oil to the water -off pot, and the refueling volume is about 75%of the pot volume. Turn on the decocent cooker to heat the steam, heat the oil temperature to about 110 ° C, and start adding the white soil.3%for oil.After the white soil is added, continue to s...

Embodiment 2

[0044] 5 tons of walnut oil oil, acid prices 6, color Rowon 25.4 mm yellow 25, red 6, peroxide value 3.5.

[0045] Hydrophobic dehydration is the same as the embodiment 1.

[0046]Walnut oil discoloration is deemed to be an embodiment 1, and the amount of white soil adds 5%.

[0047] Walnut oil physical desertic acid is the same as Example 1.

[0048] After the walnut oil was physically refined, the acid price was tested to 0.15, and the color of the color Rowon 133.4 mm yellow 10, red 2.5 peroxide 2.5. Miscellaneous less than 0.01.Refining 94%.83%higher than conventional refining.Mixed fatty acids have 3%.

Embodiment 3

[0050] 4 tons of walnut oil oil, acid price 4, color Row Peng 25.4 mm yellow 25, red 5, peroxidation value 3. 0.2%of it.

[0051] Hydrophobic dehydration is the same as the embodiment 1.

[0052] Walnut oil discoloration is deemed to be an embodiment 1, and the amount of white soil is 4%.

[0053] Walnut oil physical desertic acid is the same as Example 1.

[0054] Walnut oil prepared by the physical refining method of the present invention is reduced to 0.14 after detecting the price of acid, and the color Rowon 133.4 mm yellow 10, red 2.5 peroxidine 2.5. Miscellaneous is less than 0.01.Its refining rate is 96%, which is higher than conventional refining 87%, and the hybrid acid obtain rate is 2%.

Abstract

The invention discloses a process for physically refining walnut oil and relates to an oil processing technology. The process comprises the following steps: hydrating for degumming; decoloring; physically deacidifying and capturing fatty acid; and discharging oil. The process is unique and skillful in design and is safe and reliable in operation; and because caustic soda is not adopted for deacidification and long-time deodorization, various beneficial active ingredients in the walnut oil are well maintained, and adverse effects of the conventional processing technology on the walnut oil and the active ingredients therein are avoided.

Description

Technical field [0001] The present invention involves oil processing technology, especially a process that directly adopts physical refining methods to prepare walnut refining. Background technique [0002] Walnuts are traditional wooden oil crops. They have rich nutritional value and contain a variety of trace elements needed by the human body, such as oleic acid, linoleic acid, a variety of amino acids, trace elements and vitamins in unsaturated fatty acids.It plays a special health role in the human body and has always been favored by people.Walnut oil is a oil that is squeezed, immersed, and refined with the squeezing, immersion, and refining of walnut oil.The quality of walnuts is poor, the processing of hair oil is high and dark.Walnut oil unsaturated fatty acids have high content and are prone to oxide.Using conventional refined methods to remove acid -alkaliic acid, because alkali will neutralizes with free fatty acids in the oil, it will also react with the oil with oil,...
