Abstract

PURPOSE:To obtain a lysolecithin containing highly concentrated lysophosphatidylcholine by de-fatting a lysolecithin prepared by treating a lecithin with an enzyme and extracting the lysolecithin with a mixed solvent of CO2 in a liquid state or supercritical state and an alcohol. CONSTITUTION:An animal or vegetable derived lecithin is hydrolyzed with an enzyme (usually phospholipase A2) to give a lecithin and fat and oils are extracted from the lecithin with acetone or supercritical carbon dioxide. Then, the lecithin is extracted with a mixed solvent (preferably about 4-20wt.% alcohol) of carbon dioxide in a liquid state or supercritical state and 1-4C alcohol (water content: preferably about 10wt.%), the solvent is removed from the extracted solution to give a lecithin containing highly concentrated lysophosphatidylcholine. When carbon dioxide in a supercritical state is used as the carbon dioxide, the extraction conditions are preferably 40-60 deg.C temperature and 10-30MPa. When liquid carbon dioxide is used as the carbon dioxide, the extraction conditions are preferably -20 to 30 deg.C and 5-8MPa.

Detailed Description of the Invention (Technical Field) The present invention relates to a method for collecting necessary components from lysolecithin as a raw material, and in particular, lysolecithin containing a high concentration of lysophosphatidylcholine (LPG) among various components.

(Background Art) Because lysolecithin (lysophospholipid) has a hydroxyl group in its molecule, it has greater hydrophilicity than lecithin (phospholipid), and has the characteristic of forming an emulsion that is stable against changes in pH and temperature. Among them, lysophosphatidylcholine (LPC) is said to exhibit behavior similar to nonionic surfactants and maintains surface activity even in solutions with high salt concentrations.

このため、LPCは、食品、化粧品、医薬品等の各分野

Therefore, LPC is expected to be widely applied in various fields such as foods, cosmetics, and pharmaceuticals.

By the way, commercially available lysolecithin is produced by hydrolyzing animal and vegetable lecithin such as egg yolk lecithin and soybean lecithin with enzymes, but although the composition differs depending on the raw material, Generally, in addition to the lysophosphatidylcholine (LPC), it contains lysophosphatidylethanolamine (LPE), sophosphatidic acid (LPA), and various unreacted phospholipids that have not been lysized, and in many cases, Since it contains neutral fats and oils derived from the raw material lecithin, the LPC concentration is not very high.

In order to produce lysolecithin containing a higher concentration of LPG, a method is known in which neutral fats and oils are removed using a solvent such as acetone, and further alcohol fractionation is performed. However, this method is cumbersome to operate, and when the raw material is lysolecithin obtained from vegetable lecithin such as soybean lecithin, the raw material may contain many alcohol-soluble components other than LPG. Even if the alcohol fractionation operation is repeated, the LPG concentration remains at 70%.
Doing so has inherent problems that make it extremely difficult.

(Solution Means) In order to solve the above-mentioned problems, the present inventors have conducted extensive research and found that when defatted lysolecithin is extracted with a predetermined mixed solvent of carbon dioxide and alcohol, various glue puddings can be extracted. We discovered that lysophosphatidylcholine (LPG) is easily extracted among lipids and various unreacted phospholipids that remain without being resolized, and that unreacted phospholipids are difficult to extract, and based on this knowledge, Thus, the present invention was completed.

(Specific Structure) In the present invention, the lysolecithin to be extracted is obtained by enzymatically hydrolyzing lecithin derived from animals or plants, and may be obtained from, for example, egg yolk, bovine brain, swelling, etc. It can be obtained by reacting a predetermined enzyme with animal-derived lecithin obtained from plants such as soybeans, corn, rapeseed, and other plant-derived lecithins. Note that phospholipase A2 is usually used as the enzyme, but commercially available preparations can be used for this. Furthermore, various types of lecithin and lysolecithin have been commercialized and are commercially available, so it is possible to use them.

In addition, especially when the raw material lysolecithin is derived from vegetable lecithin, in the LPC extraction operation,
In order to facilitate the contact between the raw material lysolecithin and the extraction solvent, it is desirable to mix the lysolecithin in advance with powder that is insoluble in the extraction solvent. This is because, in general, the penetration of extraction solvent into the solid or liquid lysolecithin phase is extremely poor, and the rate of dissolution of the lysolecithin phase in the extraction solvent is slow. This is because not only does it take time and use more extraction solvent than necessary, but also there is a risk of unstable extraction with poor reproducibility due to differences in the penetration of the extraction solvent.

Therefore, if the raw material lysolecithin is mixed with powder before the extraction operation, the contact area of the lysolecithin with the extraction solvent can be greatly increased, making extraction easier. By making the flow path of the extraction solvent uniform, it is possible to make the flow of the solution uniform.

Incidentally, specific examples of such powders include those that are insoluble in the extraction solvent consisting of carbon dioxide and alcohol, which will be described later, and are inert to the raw material lysolecithin (i.e., those that do not react with the raw material lysolecithin or have a strong adsorption effect). There are no particular limitations, and starch powder, soybean protein, egg white, cellulose powder, porous silica, and the like can be used.

In addition, the mixing ratio of the powder and the raw material lysolecithin may be determined as appropriate to ensure uniform mixing, but since it is uneconomical to use more powder than necessary, the raw material lysolecithin 0 part by weight of powder or granules

Furthermore, if the raw material lysolecithin is in the form of powder or liquid, it is easy to mix it uniformly with powder or granules, but if it is solid or a liquid with extremely high viscosity, the raw material lysolecithin must be dissolved in an appropriate solvent and then mixed. , mixed with powder and granular material,
It is best to dry it afterwards. At this time, when the solvent used to dissolve the raw material lysolecithin is alcohol, which is a component of the extraction solvent described later, drying after mixing can be omitted.

In addition, in the case of lysolecithin derived from egg yolk, since the protein in the egg yolk plays the role of the above-mentioned granular material, there is no need to specifically add granular material. In short, it is only necessary to consider the addition of powder or granules to ensure uniform extraction according to the properties of the raw material.

The composition of the raw material lysolecithin prepared in this way is:
In addition to lysophosphatidylcholine (LPG), there are also lysophosphatidylethanolamine (LPE), sophosphatidic acid (LPA), and unreacted phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol that remain unreacted. (PI) etc. In the present invention, the raw material lysolecithin is subjected to an extraction operation using the following extraction solvent to obtain LP.
This allows for efficient extraction of C and significantly increases its concentration.

That is, in the present invention, a mixed solvent of carbon dioxide in a liquid state or a supercritical state and an alcohol having 1 to 4 carbon atoms is used as an extraction solvent. Among them, carbon dioxide is
Although it is well known as an extraction solvent, in the present invention it also has the effect of controlling the extraction ratio of alcohol-soluble lysolecithin and unreacted lecithin. In addition, in the supercritical state of carbon dioxide, the temperature is critical temperature: 31.1°C or more, and the pressure is critical pressure = 7

On the other hand, alcohol acts as a solvent for LPG, LPE, PC, PE, etc., and any alcohol having 1 to 4 carbon atoms can be used, and one or more of them can be appropriately combined. It will be selected based on the following. In addition,
If the number of carbon atoms is greater than 4, the solubility of lysolecithin will be low and it will virtually no longer be able to act as an extraction solvent. Further, it is desirable that the water content of the alcohol is about 10% by weight or less. This is because if water is contained in a proportion exceeding this, it may not only reduce the solubility of lysolecithin but also reduce the fractionation ability of LPC, which may have an adverse effect on the extraction of high-concentration LPG.

The mixing ratio of the alcohol and the carbon dioxide is appropriately determined depending on the composition of the raw material lysolecithin, but preferably, the blending amount of the alcohol is about 4 to 20% by weight. If the amount of alcohol blended is less than this range, the solubility of LPG will decrease and the yield will tend to drop.2 Conversely, if the mixing ratio is greater than this, the effect of carbon dioxide, which controls the solubility of lysolecithin, will decrease. This is because there is a concern that the LPG concentration will decrease and it will be difficult to increase the LPG concentration.

By the way, FIG. 1 is a flow sheet showing an example of an extraction apparatus to which the method of the present invention is applied. The extraction solvent is prepared by supplying predetermined alcohols and mixing them in a predetermined ratio on the flow path. and,
The extraction solvent is supplied into the extractor 6, which contains the raw material lysolecithin and is controlled at a predetermined temperature and pressure, and extracts LPG.

After that, the extract containing the soluble components in the raw material lysolecithin is taken out of the extractor 6 and passed through the separators 8 and 10.
In the process, the pressure is first returned to normal pressure and separated into -carbon oxide and alcohol solution. Next, the alcohol is removed by vacuum distillation using a conventional method to obtain lysolecithin containing the desired high concentrations of r and pc. Note that 35 is a pump, 12 is a flow meter, and 14 is an integrating gas meter.

More specifically, in the above extraction operation, generally speaking, the lower the temperature or the higher the pressure, the greater the solubility of the raw material lysolecithin in the extraction solvent. On the other hand, if unreacted phosphatidylcholine (PC) remains in the raw material lysolecithin, PC will be extracted together with LPG, so in that case, it is better to set the extraction temperature slightly higher. The more specific temperature and pressure conditions will be appropriately selected depending on the target LPC concentration and yield, the composition of the raw material reglecitin, etc., but in general, the temperature is 70°C. If the temperature exceeds 45 MPa, there is a problem in that lysolecithin undergoes significant thermal deterioration, excessively low temperature extraction is not economical, and if the pressure exceeds 45 MPa, there are problems in equipment design and maintenance. When using carbon oxide in a supercritical state, temperature = 31-65°C, pressure 8-45M
The range of Pa is preferable, and more preferably, the temperature is 40 to 60° C. and the pressure is 10 to 30 MPa.

Further, when carbon dioxide in a liquid state is used, a temperature range of 20 to 30° C. and a pressure of 5 to 8 MPa is preferable.

In this way, the defatted raw material lysolecithin,
When an extraction solvent consisting of carbon dioxide and alcohol is applied, LPC is extracted most efficiently among various lysolecithins and unreacted lecithin, while unreacted lecithin is difficult to extract, especially PI. Very little is extracted. Therefore, by going through this extraction operation, most of the PI remains as a residual component, and it is also effectively suppressed that large amounts of lysolecithin other than LPG and unreacted lecithin are mixed into the extract. This makes it possible to significantly increase the LPC concentration of extracted lysolecithin.

The specific extraction time is determined as appropriate depending on the scale of the extraction device, the amount of mixed solvent of carbon dioxide and alcohol fed, other extraction conditions, and the composition of the raw material lysolecithin. If the time is too long, alcohol-soluble components other than LPG will gradually become mixed in, so it is generally desirable to collect the extraction fraction at a relatively early stage after the start of extraction.
