Problems solved by technology

[0005] At present, the refining of unsaturated fatty acids is to treat unsaturated fatty acid triglycerides, and use sodium methoxide or sodium ethoxide to convert unsaturated fatty acid triglycerides into unsaturated fatty acid methyl or ethyl esters in the presence of methanol or ethanol. Carry out vacuum distillation again, this kind method has the following disadvantages: 1. There is the residue of organic solvent in the seal oil after refining, and a lot of components that we do not need are mixed in the obtained seal oil; 2. This method is loaded down with trivial details to deal with seal oil crude oil , adding many steps and costs
[0006] At present, under the condition of not changing the form of unsaturated fatty acid triglyceride in seal oil, how to refine the OMEGA3 unsaturated fatty acid in seal oil to 25% has not been reported yet

Embodiment 1

[0031] Equipment: German VTA short-range molecular distillation apparatus is adopted, with a distillation area of ​​0.4m 2 .

[0032] Raw material: seal oil crude oil 50 kg.

[0033] Conditions: two-stage vacuum distillation is adopted, the pressure of the first pole molecular still is 10Pa; the pressure of the second pole molecular still is 0.01-0.3Pa; the feed rate is 10 kg / hour; the evaporation temperature of the first pole is 140°C , the evaporation temperature of the second pole is 300°C; the rotational speed of the wiped film rotor of the first pole is 100 rpm, and the rotational speed of the wiped film rotor of the second pole is 250 rpm.

[0034] operate:

[0035] 1 Routine inspection before starting the instrument

[0036] Before each molecular distillation experiment, the following items need to be checked routinely:

[0037] 1.1 Check whether the cooling and heating circuits are connected smoothly

[0038] 1.2 Check whether there is pump oil in the vacuum pump,...

Embodiment 2

[0068] Method is with embodiment 1.

[0069] The conditions are: the pressure of the first pole molecular still is 5Pa, the pressure of the second pole still is 0.1~0.3Pa; the feed rate is 8kg / h; the evaporation temperature of the first pole is 140°C, and the evaporation temperature of the second pole is The temperature is 300° C.; the rotation speed of the first pole wiped film rotor is 100 rpm, and the second pole wiped film rotor speed is 250 rpm.

[0070] After 6.25 hours, 21.7 kg of heavy fraction was obtained.

[0071] Through content determination, the content of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) in the prepared OMEGA3 unsaturated fatty acid is 30%-40% .

Embodiment 3

[0073] Method is with embodiment 1.

[0074] The conditions are: the pressure of the first pole molecular still is 1Pa, the pressure of the second pole still is 0.05~0.1Pa; the feed rate is 5kg / h; the evaporation temperature of the first pole is 140°C, and the evaporation temperature of the second pole is The temperature is 300° C.; the rotation speed of the first pole wiped film rotor is 100 rpm, and the second pole wiped film rotor speed is 250 rpm.

[0075] After 10 hours, 16.1 kg of heavy component was obtained

[0076] Through content determination, the content of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) in the prepared OMEGA3 unsaturated fatty acid is 40%-50% .

Abstract

The invention relates the method of refining OMEGA3 unsaturated fatty acid from ursine seal oil, comprising the following steps: using distilling apparatus to refine OMEGA3 unsaturated fatty acid, and using two-grade vacuum distillation. The press of the first molecular distillation is 0.01-20Pa, and the press of second molecular distillation is 0.005-1Pa.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a method for refining OMEGA3 unsaturated fatty acids from seal oil, and the OMEGA3 unsaturated fatty acids exist in the state of triglycerides as before the refining. Background technique [0002] Fur seal is a common name for the harp seal (Harp seal), which lives in the Arctic and the northern part of the Atlantic Ocean. Due to conservation measures taken by the Canadian government, fur seal populations are growing steadily at a rate of 5% per year. In order to maintain the ecological balance between fur seals and fish schools, with the approval of the United Nations and the Canadian government, a small amount of fur seals can be killed each year. [0003] This product is made from the subcutaneous fat of newly hunted arctic fur seals. After vacuum distillation and other processes, proteins, carbohydrates and other substances are removed under low temperature cond...
