Description
Technical Field
The invention relates to the field of manufacturing of functional food raw materials and medicine raw materials, in particular to a preparation method for simultaneously obtaining high-purity squalene and phytosterol.
Background
In the refining process of vegetable oil, in order to make the oil have higher quality, the oil needs to be adsorbed by an adsorbent to remove impurities, for example, the oil needs to be decolorized by an adsorbent such as activated carbon, activated clay, attapulgite, bentonite and the like, and in medicinal oil, the oil needs to be further purified by an adsorbent such as silica gel, alumina and the like. However, the adsorbent can absorb impurities and also can inevitably absorb partial beneficial oil components such as triglyceride, squalene, tocopherol, phytosterol and the like. The adsorbent after adsorbing the grease is generally treated as waste residue, and if the adsorbent is not recycled, the beneficial components in the waste residue of the adsorbent are separated, so that great resource waste can be caused.
Squalene and phytosterol are accompanying nutritional ingredients in vegetable oil, wherein squalene is colorless liquid, has various pharmacological activities, can improve cell activity, improve anoxic state of cardiovascular and cerebrovascular diseases, and can be used for hypercholesterolemia and leukopenia caused by radiotherapy and chemotherapy. The plant sterol is a substance with a cyclic alcohol structure, can reduce the cholesterol level in serum, prevent and treat heart diseases such as coronary atherosclerosis, and has obvious curative effects on ulcers, skin squamous cell carcinoma, cervical cancer and the like.
In the prior art, squalene and phytosterol mainly take vegetable oil or vegetable oil deodorization distillate and the like as raw materials, and adopt esterification, saponification, molecular distillation, column chromatography and supercritical C0 2 The preparation method comprises the steps of extraction, inclusion, crystallization and other technologies.
Patent CN202111131385 (method for recovering bioactive components from waste activated clay subjected to vegetable oil decolorization) discloses a method for recovering bioactive components from waste activated clay by means of ultrasonic extraction and gradient elution with an organic solvent, wherein the tocopherol, squalene and phytosterol obtained by the method are low in content and are a mixture.
Patent CN201610717836, "method for recovering squalene, vitamin E and/or sterol", discloses a method for extracting squalene, sterol and vitamin E from a residue from vitamin E production, by adsorption using a polar adsorbent and a nonpolar solvent, a polar solvent, solid-liquid phase separation and crystallization process, a squalene-containing product and/or a sterol-containing crystalline product and/or a vitamin E-containing product are obtained. But the content of squalene in the extracted squalene-containing product is more than 30%, the content of sterols in the sterol-containing crystal product is more than 75%, and the content of vitamin E in the vitamin E-containing product is more than 30%.
Patent CN201611125250, "a method for extracting squalene from grease", adopts a method of glycerolysis of lipase, inclusion of cyclodextrin and adsorption separation of alumina to extract squalene from grease, and the method only obtains high-purity squalene.
Patent CN202010728500 (method for separating squalene from fructus Siraitiae Grosvenorii extract residue) comprises extracting with alkaline low-carbon alcohol, drying, mixing with silica gel, extracting with supercritical carbon dioxide, and extracting with solvent to obtain squalene; the sitosterol and the momordica grosvenori are respectively obtained by the operations of silica gel column chromatography and the like after the sample is mixed, and the operations are complex.
Patent CN202211106716 (method for enriching polyunsaturated fatty acid esters, squalene, natural vitamin E and plant sterols) from plant deodorization distillate, wherein the plant deodorization distillate is added with short-chain alcohol and an emulsifying agent or an auxiliary emulsifying agent for emulsification, low-temperature enzymatic esterification, gradient freezing crystallization, pressure filtration, multistage rectification, urea complexation and other operations to respectively obtain the plant sterols, the squalene, the natural vitamin E and the polyunsaturated fatty acid esters. The operation is complex, and the content of squalene and phytosterol is below 70%.

Disclosure of Invention
The invention aims to provide a novel method for extracting high-purity squalene and phytosterol, and simultaneously comprehensively utilizes adsorbent waste residues after vegetable oil absorption, so that resource waste is reduced.
In order to solve the technical problems, the invention adopts the following technical scheme:
a preparation method for simultaneously obtaining high-purity squalene and phytosterol comprises the following steps:
A. taking oil absorption waste residues, and adding the oil absorption waste residues in a volume mass ratio of 2-10L: the mass ratio of 1kg of the first organic solvent to the oil absorption waste residue is 0.06-2 kg:1kg of alkali, heating, refluxing and stirring, standing, cooling, separating liquid, and concentrating to obtain concentrate;
B. the concentrate takes a chromatographic column filled with a mixed adsorbent as a stationary phase, and the volume mass ratio of the concentrate to the adsorption waste residue is 0.5-3L: eluting with 1kg of first organic solvent as mobile phase, collecting eluting fraction, concentrating, and drying to obtain squalene product;
C. the volume mass ratio of the oil absorption waste residue to the oil absorption waste residue is 1-4L: and (3) taking 1kg of a second organic solvent as a mobile phase, eluting the chromatographic column again, collecting the eluted fraction, concentrating, and drying to obtain a phytosterol product.
Some vegetable oils have high levels of squalene and phytosterols, and some of these vegetable oils inevitably become adsorbed by the adsorbent and remain in the adsorbent waste residue during the refining process. However, the presence of triglycerides can affect subsequent separation of squalene and phytosterols. In the prior art, the hydrolysis of saponified triglycerides to form fatty acid salts and glycerin is typically carried out using an alcoholic solution of a base. However, since the fatty acid salt, glycerin, phytosterol, squalene, and the rest of alkali are all soluble in the alcohol solution, the subsequent operations such as multi-step solvent extraction and back extraction, water washing and the like are required, and a large amount of solvents are required to be consumed and a large amount of wastewater is generated. In the technical scheme, alkane solvents are selected as extraction solvents, so that excessive alkali, fatty acid salts and glycerol can be well prevented from being dissolved in the extraction solvents, and plant sterols and squalene can be selectively extracted. In addition, experiments show that the hydrolyzed glycerol has larger polarity, so that sterol components are promoted to be resolved from adsorbent waste residues, and the extraction efficiency of the alkane solvent is further improved.
Therefore, the invention discards the traditional extraction mode adopting alcohol solvent, changes the low-polarity alkane solvent into the low-polarity alkane solvent, avoids the residual fatty acid salt, glycerol and redundant alkali in the extraction solvent, avoids the subsequent operations of further extraction, water washing and the like, and can be realized through simple separation operation.
Preferably, in the step B, the mixed adsorbent comprises polyacrylamide accounting for 1-8% of the total mass of the mixed adsorbent.
A small amount of free fatty acid and its salt generated by hydrolysis are inevitably remained in the preparation process. Polyacrylamide is a high molecular organic polymer, has good adsorption characteristics, and particularly has strong adsorption and fixation capacity on large polar substances and anionic substances.
Preferably, in the step B, the mixed adsorbent further comprises one or more of silica gel, amino silica gel, diol silica gel and silica.
The invention uses a small amount of polyacrylamide and silica gel adsorbent as mixed adsorbent, which unexpectedly enhances the separation effect of the concentrate, reduces the use amount of solvent, and ensures that the purities of squalene and phytosterol are more than 95 percent, thus obtaining unexpected effect.
Preferably, the first organic solvent comprises one or more of pentane, hexane, heptane, octane, petroleum ether; the second organic solvent comprises one or more of dichloromethane, chloroform, diethyl ether, ethyl acetate, methanol, ethanol, isopropanol and acetone.
Preferably, the specific operation of step a includes: the volume mass ratio of the first organic solvent, the alkali and the oil absorption waste residue is controlled to be 2-10L: 0.06-2 kg:1kg, heating, refluxing and stirring for 0.5-3 hours, standing, naturally cooling, separating out liquid, and concentrating to obtain the concentrate; in the step B, the mass ratio of the mixed adsorbent to the oil absorption waste residue is 0.05-0.18 kg:1kg.
Preferably, step a further comprises: the first organic solvent is recovered during concentration and used in the elution of step B.
Preferably, in the step a, the oil absorption waste residue includes adsorbent waste residue obtained by separating after adsorbing vegetable oil.
Preferably, the vegetable oil comprises one or more of olive oil, rice bran oil, tea oil, linseed oil, momordica grosvenori seed oil, wild jasmine seed oil, pumpkin seed oil, amaranth oil, peony seed oil and corn oil; the adsorbent in the adsorbent waste residue comprises one or more of active carbon, activated clay, bentonite, attapulgite, diatomite, florisil silica, silica gel, silicon dioxide, aluminum oxide and aluminum silicate; the method for separating out the liquid comprises one or more of standing and layering, centrifuging and filtering.
A squalene product obtained according to the above process for producing squalene and phytosterols simultaneously having high purity.
A phytosterol product obtained according to the above process for the preparation of squalene and phytosterols simultaneously obtained in high purity.
Compared with the prior art, the implementation of the invention has the following beneficial effects:
(1) The invention avoids complex operation, large amount of solvent use and wastewater generation by combining one-step alkali hydrolysis-solvent extraction with column separation technology.
(2) The invention improves the squalene and the phytosterol which are obtained in high purity by improving the column separation capability.
(3) The invention takes the waste residue of the adsorbent generated in refining vegetable oil as raw material, which can improve the utilization rate of resources.
Detailed Description

Example 1
Taking 2kg of active carbon waste residue obtained by separating after corn oil adsorption, adding 5L of n-hexane and 0.16kg of sodium hydroxide, heating and refluxing for 2 hours, standing for cooling, filtering, and concentrating filtrate to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 10g polyacrylamide and 190g silica gel, eluting with 2L of n-hexane, discarding the front-stage eluent, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with purity of 99.4%; eluting with 4L dichloromethane, collecting dichloromethane eluate, concentrating, and drying to obtain phytosterol product with purity of 97.8%.

Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 6g of anionic polyacrylamide and 290g of silica gel, eluting with 4L of n-heptane, discarding the front-end eluent, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with the purity of 99.1%; eluting with 2L chloroform, collecting chloroform eluate, concentrating, and drying to obtain phytosterol product with purity of 97.2%.

Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 2g of anionic polyacrylamide and 98g of amino silica gel, eluting with 1L of n-hexane, discarding the front-stage eluent, collecting an elution fraction containing squalene, concentrating, and drying to obtain a squalene product with the purity of 99.1%; eluting with 2L of dichloromethane, collecting dichloromethane eluting fraction, concentrating, and drying to obtain phytosterol product with purity of 97.2%.
Example 4
Taking 2kg of activated carbon and silica gel waste residue obtained by separating after the adsorption of olive oil, adding 15L of n-hexane and 0.4kg of potassium hydroxide, heating and refluxing for 2 hours, standing still for cooling, filtering, and concentrating the filtrate to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 10g of anionic polyacrylamide and 190g of glycol-based silica gel, eluting with 5L of n-octane, discarding the eluent at the front stage, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with the purity of 98.3%; eluting with 6L ethanol, collecting methanol eluate, concentrating, and drying to obtain phytosterol product with purity of 97.5%.
Example 5
2kg of attapulgite waste residue obtained by separating amaranth oil is taken, 10L of n-octane-diethyl ether (1:1) and 0.4kg of calcium hydroxide are added, heating reflux is carried out for 2 hours, standing still for cooling, centrifugation is carried out, and filtrate is concentrated to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 12g of anionic polyacrylamide and 138g of glycol-based silica gel, eluting with 3L of petroleum ether, discarding the eluent of the previous stage, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with the purity of 98.3%; eluting with 8L methanol, collecting methanol eluate, concentrating, and drying to obtain phytosterol product with purity of 97.5%.
Comparative example 1
Taking 2kg of active carbon waste residue obtained by separating after corn oil adsorption, adding 5L of ethanol and 0.16kg of sodium hydroxide, heating and refluxing for 2 hours, standing still for cooling, filtering, adding 5L of water into filtrate, extracting 3 times with n-hexane for 10L each time, washing n-hexane extract with water for 3 times with 10L each time, and concentrating the n-hexane extract to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with 200g of silica gel mixed adsorbent, eluting with 2L of n-hexane, discarding the front-stage eluent, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with purity of 94.0%; eluting with 4L dichloromethane, collecting dichloromethane eluate, concentrating, and drying to obtain phytosterol product with purity of 78.5%.
As can be seen from comparative example 1, the saponification treatment with an alcoholic solution of a base requires removal of impurities by multiple extractions and water washes, consumes a large amount of extraction solvent and water, and is separated and purified using conventional silica gel column chromatography, while a squalene product of higher purity can be obtained, the phytosterol product is of lower purity.
Comparative example 2
Taking 2kg of active carbon waste residue obtained by separating after corn oil adsorption, adding 5L of n-hexane and 0.16kg of sodium hydroxide, heating and refluxing for 2 hours, standing for cooling, filtering, and concentrating filtrate to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with 200g of silica gel adsorbent, eluting with 2L of n-hexane, discarding the front-stage eluent, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with purity of 95.4%; eluting with 4L dichloromethane, collecting dichloromethane eluate, concentrating, and drying to obtain phytosterol product with purity of 87.8%.
As can be seen from comparative example 2, the concentrate obtained by the present technical scheme can be separated and purified by silica gel column chromatography without polyacrylamide to obtain squalene product with higher purity, and the purity of the phytosterol product is improved (compared with comparative example 1), but more than 95% of the phytosterol product can not be obtained.
Comparative example 3
Taking 2kg of active carbon waste residue obtained by separating after corn oil adsorption, adding 5L of n-hexane and 0.16kg of sodium hydroxide, heating and refluxing for 2 hours, standing for cooling, filtering, and concentrating filtrate to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 18g polyacrylamide and 182g silica gel, eluting with 2L of n-hexane, discarding the front-stage eluent, collecting the elution fraction containing squalene, concentrating, and drying to obtain squalene product with the purity of 97.6%; eluting with 10L of dichloromethane, collecting dichloromethane eluting fraction, concentrating, and drying to obtain phytosterol product with purity of 90.1%.
As can be seen from comparative example 3, when the amount of polyacrylamide exceeds 8% of the mass of the mixed adsorbent, more of the second organic solvent is required for elution, and the purity of the obtained phytosterol product is lowered.
Comparative example 4
Taking 2kg of activated clay waste residue obtained by separating the absorbed momordica grosvenori kernel oil, adding 8L of n-hexane and 0.3kg of potassium hydroxide, heating and refluxing for 1.5 hours, standing still for cooling, filtering, and concentrating filtrate to obtain a concentrate. Adding the concentrate to the upper end of a chromatographic column filled with a mixed adsorbent of 2g of anionic polyacrylamide and 98g of amino silica gel, eluting with 2L of dichloromethane, collecting dichloromethane elution fraction, concentrating and drying to obtain a squalene and phytosterol mixed product, wherein the squalene content is 63.7% and the phytosterol content is 15.2%; eluting with 1L of n-hexane, concentrating, drying, and collecting sample containing small amount of phytosterol with purity of 33.9%.
As can be seen from comparative example 4, the mixed product of squalene and phytosterol is obtained by eluting with dichloromethane, and the purity is low, so that the separation and purification effects are not achieved. It can be seen that the order of use of the first organic solvent and the second organic solvent can have a significant impact on the separation and purification effect.
The foregoing disclosure is merely illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the claims herein, as equivalent changes may be made in the claims herein without departing from the scope of the invention.
