Description

  The present invention relates to an extract from a sturgeon egg, and more specifically to a sturgeon egg extract obtained by using a specific extraction method.

  There is a strong demand for cosmetics that bring about excellent effects on the skin, hair, and the like and realize a youthful state, in particular, whitening effects, moisturizing effects, anti-aging effects, and the like. Such cosmetics often contain various extracts, but there are few studies on cosmetics containing extracts from eggs. For example, cosmetics that use an extract of a fertilized chicken egg to enhance the effectiveness of the skin-beautifying action, particularly by eliminating the roughening property, and are less anxious about safety are disclosed (Patent Documents 1 and 2).

  However, compared to an example using an extract from an egg of a bird such as a chicken, little is known about cosmetics using an extract from an egg of a fish such as sturgeon. For example, Patent Documents 3 and 4 disclose cosmetics in which an active ingredient is encapsulated in an easily friable caviar-like capsule whose surface only becomes a film, but the shape is caviar-like. That is, the cosmetic ingredients were completely different.

  Little is known about cosmetics using extracts from sturgeon eggs. In addition to sturgeon itself being a precious animal, mainly sturgeon eggs are always salted and edible as caviar. Because it was. Furthermore, regarding the extract from an egg, there existed a problem that an oil-soluble component and a water-soluble component were mixed in the egg, and each component could not be extracted efficiently. There is also a problem that the extract cannot be obtained without impurities or turbidity. In particular, extracts from fish eggs such as sturgeon have a unique raw odor, and it is difficult to obtain an extract without such odor.

  On the other hand, in order to adjust the color tone suitable for cosmetics and the content of the extract, studies on extraction solvents and washing processes are also disclosed (Patent Document 2). In addition, in order to increase extraction efficiency, an extraction method such as repeating an extraction process is also known (Patent Document 5). However, a method for efficiently obtaining each component from an egg in which an oil-soluble component and a water-soluble component are mixed without impurities and turbidity has not been known. In addition, there has been no known method for obtaining an extract that has a unique raw odor, such as sturgeon eggs, and that has no odor to the extent that it can be used for cosmetics, for example.

  The demand for cosmetics to achieve a beautiful skin condition is increasing, and such known technology is not enough to respond to the demands of consumers by using ingredients of sturgeon eggs that have excellent effects as cosmetics. Sufficient and further development was desired.

JP 2006-249045 A JP 2005-272380 A JP-A-5-092909 JP-A-8-175932 JP 2005-168352 A

  The present invention has been made in view of the above-mentioned background art, and the problem is that each component is extracted efficiently from sturgeon eggs containing both oil-soluble components and water-soluble components in a state free from impurities and turbidity. It is intended to provide a method for obtaining a product, and further provides an excellent moisture retention effect, anti-aging effect, whitening effect, etc. to the skin or hair, and realizes a youthful skin and hair condition. And to provide a cosmetic using the same.

  As a result of intensive studies to solve the above problems, the present inventors have found that the above problems can be achieved by using a specific extraction method, and have completed the present invention.

  That is, the present invention is characterized in that a component soluble in a solvent is substantially removed from a sturgeon egg using a solvent and then extracted with a solvent having a different compatibility with water. A sturgeon egg extract is provided.

  In addition, the present invention substantially removes components soluble in an organic solvent from a sturgeon egg using “an organic solvent that is not compatible with water at 30 ° C. in any proportion” (A1), Alternatively, the sturgeon egg extract according to claim 1, which is extracted with an organic solvent (B1) compatible with water at an arbitrary ratio at 30 ° C. (hereinafter abbreviated as “Aspect 1”). ).

  Further, the present invention substantially eliminates components soluble in the solvent from sturgeon eggs using “organic solvent compatible with water or water at an arbitrary ratio at 30 ° C.” (B2), The sturgeon egg extract according to claim 1, which is extracted with an organic solvent (A2) that is incompatible with water at an arbitrary ratio at 30 ° C (hereinafter abbreviated as "Aspect 2"). .

  The present invention also provides a cosmetic comprising the above sturgeon egg extract.

  According to the present invention, sturgeon egg extract dissolved in purified “water or an organic solvent compatible with water at 30 ° C. in any proportion” or purified “optional at 30 ° C. in water A sturgeon egg extract dissolved in two kinds of solvents each of a sturgeon egg extract dissolved in an “organic solvent incompatible with each other” can be efficiently obtained.

  As a result, a sturgeon egg extract suitable for each of water-soluble and oil-soluble cosmetics can be obtained, and therefore a series of cosmetics containing the series of sturgeon egg extracts of the present invention can be prepared by using them appropriately. . Furthermore, in order to obtain an extract with the other solvent after previously removing the soluble component in the solvent with one solvent, the soluble component in one solvent (to the other solvent) is obtained as the extract with the other solvent. Insoluble components) and the like are free of turbidity and impurities. Furthermore, ingredients that cannot function as cosmetics and fish-derived odors can be removed at the same time by extraction with one solvent in advance, resulting in a sturgeon egg extract dissolved in each solvent with few impurities. It is done.

  In addition, the soluble component is removed in advance with one solvent, but by effectively using the extract, it is possible to minimize the waste of sturgeon eggs and maximize the use of expensive sturgeon eggs. .

  Further, according to the present invention, it is possible to provide an effective cosmetic for realizing a youthful skin and hair by providing the skin or hair with excellent moisturizing effect, anti-aging effect, whitening effect and the like.

  Hereinafter, the present invention will be described. However, the present invention is not limited to the following embodiments, and can be arbitrarily modified and implemented.

  The present invention is a cosmetic comprising a sturgeon egg extract. In the present invention, “sturgeon” refers to fish belonging to the order Sturgeon, Sturgeonidae. There are about 30 species of natural or farmed sturgeon, all of which are currently identified, any of which can be used. Specific examples thereof, Acipenser baeri, Acipenser brevirostrum, Acipenser dabryanus, Acipenser fulvescens, Acipenser gueldenstaedti, Acipenser mediradoi, Acipenser naccarii, Acipenser nudiventris, Acipenser oxyrinchus, Acipenser persicus, Acipenser ruthenus, Acipenser schrencki, Acipenser sinensis, Acipenser stellatus, Acipenser sturio, Acipenser transmontanus Huso dauricus, Huso huso, Pseudoscaphirhynchus fedtschenkoi, Pseudoscaphirhynchus hermannii, Pseudoscaphirhynchus kaufmanni, Scaphirhynchus albus, Scaphirhynchus platorynchus, Scaphirhynchus suttkusi and the like.

  The eggs used in the present invention may be any of the sturgeon eggs, but are preferably Amur sturgeon, white sturgeon, Siberian sturgeon, sturgeon or vestel sturgeon. Vestel sturgeon is a kind of sturgeon artificially created from a female Beluga sturgeon and a male sturgeon, and is made by crossing such an F1 Vaster sturgeon with an F1 Vaster sturgeon, a Beluga sturgeon or a sturgeon F2 Vaster Sturgeon is also called “Vaster Sturgeon”. Any egg is preferred in the present invention. The sturgeon is a Japanese name, also known as Aspensar South in scientific name and Surluyazi in dew.

  The sturgeon has a well-established aquaculture technology and is preferable in terms of protecting the natural environment. In addition, since the import and export of cosmetics containing 0.05 mg or more of an extract from all kinds of natural sturgeon eggs is prohibited by the Washington Convention, the above-mentioned sturgeon that can be cultivated is also preferable in this respect.

  There are no particular restrictions on how to remove the eggs from the sturgeon, but (1) a method that kills and dismantles a living sturgeon, and then removes the egg from it. A method of returning to the original state while alive, (3) a method of squeezing the egg from the sturgeon and returning it to the original state while alive, etc. are preferred. Among these, the method (2) or (3) is particularly preferable in that the sturgeon can be used a plurality of times. In addition, as described later, in the present invention, it is preferable to use an ovulation egg that is still in the body after ovulation, rather than an ovary egg that has been incubated and wrapped in a follicular tissue before ovulation. Then, the method (2) or (3) is possible without being limited to the method (1). Also in that respect, the method (2) or (3) in which the sturgeon can be used a plurality of times is particularly preferable in the present invention.

  There is no particular limitation on the timing and method of extracting the extract from the sturgeon egg, but the sturgeon egg used for the extraction is either immediately after being taken out of the sturgeon or frozen immediately after being taken out of the sturgeon. It is preferred that Otherwise, the extract has a raw odor, and the cosmetic containing the extract also has a raw odor, which may be undesirable as a cosmetic. In addition, the extract may change color over time or insolubles may precipitate. It is particularly preferable that the egg is immediately frozen after it is taken out, and further extracted from an egg that is always kept frozen until the extraction operation.

  Immediately after taking out an egg from a sturgeon, if it is frozen immediately after being washed with about 0.9% by mass of physiological saline, it is included in the “immediate freezing”. Since body cavity fluid such as blood is removed by performing a washing treatment with about 0.9% by mass of physiological saline, it is particularly preferable for the present invention. When treated with water instead of physiological saline, water may penetrate into the egg.

  Eggs taken out of sturgeon are not salted, so that the extract or the cosmetic containing it does not contain salt and does not adversely affect the skin. It is preferable in that an active ingredient such as a peptide is not denatured or decomposed and can be an obstacle to the production of a cosmetic. Furthermore, the salted egg may be preserved for a long period of time and have a strong raw odor (fish odor). From this point of view, it is preferable that the egg has not been salted.

  Since sturgeon eggs were mainly used for food, the sturgeon eggs were always salted (also called “salthouse”) immediately after removal and became caviar. Here, the “salting treatment” refers to treatment with 3 to 10% by mass of normal saline, and is different from the above “treatment with physiological saline”. “Caviar” refers to eggs that have been taken out of sturgeon, washed with physiological saline if necessary, and then salted. Thus, conventionally, after taking out an egg from a sturgeon, it is not immediately frozen, and a “salting process” for providing salt or saline is always performed. When frozen without salting, the egg shape will be easily crushed (drip) when thawed, and it will be of no commercial value as an edible caviar. It was never thought of freezing without applying.

  The operation of removing eggs from sturgeon and extracting immediately without salting, or immediately freezing without salting and extracting after storage is very unique in the art. Furthermore, by carrying out this very specific operation, it becomes possible to obtain a remarkable effect that an extract without a raw odor can be obtained, and it is possible to use it for a more excellent cosmetic. Also, if the egg shape collapses after thawing, there is no commercial value for edible use, but there is no problem in obtaining the extract, so that is also a disadvantage of freezing without salting treatment. The “egg shape collapse” is not a problem in the present invention.

  Conventionally, only the salted egg (caviar) was known, and its use in cosmetics was refrained. Or even if it tries to use it for cosmetics after removing salt, salt may not fully come off and a problem may arise. Even if an extract from caviar is included in the cosmetic, the function that it originally has may not be sufficiently reflected in the cosmetic.

  “Immediately frozen” after “take out from sturgeon” means “within a short time” and does not exclude insertion of an arbitrary process in the meantime. Specifically, it usually refers to within 2 hours, preferably within 1 hour, particularly preferably within 30 minutes. The above-mentioned “treatment with physiological saline” is preferably performed during this time. The freezing temperature is not particularly limited, but is preferably -80 ° C to -20 ° C. Moreover, it is preferable to perform extraction operation immediately after thawing.

  The extract extracted from the sturgeon egg contained in the cosmetic of the present invention is preferably not treated with any substance other than sodium chloride. Examples of the “substance other than salt” include antiseptics, salts other than salt, antioxidants, stabilizers, and the like.

  If the extract contained in the cosmetic of the present invention is extracted from a sturgeon egg, the stage of the egg used is not limited, and even if it is an ovarian egg before incubating and ovulation, Although it may be an ovulated egg still existing in the body after ovulation or a laid egg laid, it is preferably an ovulated egg. In the present invention, the term “ovulatory egg” refers to an egg that has been ovulated before being laid out of the sturgeon. Moreover, the egg used may be an infertile egg or a fertilized egg.

  Traditionally, sturgeon eggs are generally known only as caviar, but “caviar” is a sturgeon killed and disassembled to take out ovarian eggs before ovulation and salted. Ovulators that are still in the body after ovulation (naturally before fertilization) are easily affected by osmotic pressure, and when salted, the shape of the egg cannot be maintained, and it is not useful as caviar, that is, edible. Therefore, it was hardly used. That is, only a very small amount of ovulated eggs was used to obtain fry.

  In the present invention, it is preferable to use an ovulatory egg rather than the ovarian egg. In the case of an ovarian egg, even if it is a part of it, if you try to remove it from the sturgeon body, you must kill the sturgeon, but if it is an ovulatory egg, cut the sturgeon alive as described above. Thus, it is preferable to take out the egg and return it to its original state, or to squeeze the egg from the sturgeon and return it to its original state, which protects the sturgeon. That is, if the sturgeon is alive, it is preferable because egg cells that have not been ovulated yet and remain in the sturgeon's body grow in the sturgeon's body and ovulate several years later.

  As described above, ovulated eggs may be broken (drips) when they are salted, and even if the ovulated eggs are removed from the sturgeon and immediately frozen without salting, Although the shape can be maintained, the egg may crack (drip) when thawed, and in any case it will be worthless if edible. However, in the present invention, there is no problem in obtaining an extract from an egg even if it is broken. From this point of view, ovulation is preferred because the disadvantage of ovulation does not become a problem.

  In the present invention, a component soluble in the solvent is substantially removed from the sturgeon egg using the solvent (P), and then extracted with a solvent (Q) having a different compatibility with water from the solvent. A sturgeon egg extract characterized by According to the present invention, a sturgeon egg extract using the solvent (Q) as a solvent, which exhibits the above-mentioned effects, for example, the effects of low impurities, low turbidity and odor, and the like can be obtained. In addition, when the solvent (P) is used to substantially remove components soluble in the solvent (P), there is also an effect that a sturgeon egg extract of the solvent (P) can be prepared at the same time. Here, “solvents having different compatibility with water” refer to solvents having different degrees of hydrophilicity. In the present invention, when the oil-soluble component is substantially removed with the solvent (P) and the water-soluble component is extracted with the solvent (Q), the water-soluble component is substantially removed with the solvent (P). It is divided when extracting oil-soluble components.

(Aspect 1)
In aspect 1 of the present invention, after substantially removing a component soluble in an organic solvent from a sturgeon egg using “an organic solvent that is not compatible with water at 30 ° C. in any proportion” (A1), A sturgeon egg extract obtained by extraction with "water or an organic solvent compatible with water at 30 ° C in an arbitrary ratio" (B1).

  The “organic solvent incompatible with water at 30 ° C. at an arbitrary ratio” (A1) is not particularly limited as long as it satisfies the above conditions, but it is a monohydric alcohol having 4 to 8 carbon atoms, 4 carbon atoms. 10 esters, aliphatic hydrocarbons, aromatic hydrocarbons, ketones having 3 to 8 carbon atoms, chain ethers, cyclic ethers and halogenated hydrocarbons. A seed solvent is preferred. In addition, a case where two or more kinds are mixed to form an “organic solvent incompatible with water at an arbitrary ratio at 30 ° C.” is also included. Specifically, for example, 1-butanol, 2-butanol, pentanol, hexanol, heptanol, octanol, ethyl acetate, propyl acetate, butyl acetate, methyl propionate, ethyl propionate, methyl butyrate, methyl valerate, pentane, Examples include hexane, cyclohexane, benzene, toluene, xylene, methyl ethyl ketone, methyl butyl ketone, diethyl ether, dipropyl ether, acetonitrile, chloroform, 1,1,1-trichloroethane. These are used alone or in combination.

  The operation of substantially removing components soluble in an organic solvent refers to an operation of substantially removing components soluble in the organic solvent (A1) used by washing, dipping, etc. It is preferable to remove substantially all components soluble in the organic solvent (A1). Thereby, the insoluble matter in the solvent (B1) is removed. Specifically, known extraction methods such as immersion extraction and Soxhlet extraction can be used. In addition, any of batch operation, semi-continuous operation, and continuous operation can be used. The above operation is not limited to a single operation. A fresh solvent (A1) is added again to the residue after the operation, and the same operation can be performed again.

  Although there is no limitation in particular as the quantity of the organic solvent (A1) to be used, 0.5 mass part-100 mass parts are preferable with respect to 1 mass part of sturgeon eggs used as a raw material, and 1 mass part-30 mass parts are more. 2 parts by mass to 10 parts by mass are particularly preferable. If the amount of the organic solvent (A1) used is less than this range, the solvent may not spread over the entire raw material or may be saturated, and the removal of soluble components may be insufficient. Even when an excessive amount of solvent is added, the amount of components soluble in the solvent no longer increases, and when an extract with this organic solvent (A1) is also used, the solvent removal work in the subsequent concentration step May increase the burden.

  The temperature at which the soluble component is substantially removed using the above-mentioned “organic solvent incompatible with water at 30 ° C. in any proportion” (A1) depends on the boiling point of the solvent used, but preferably 10 The boiling point of the solvent at normal pressure, more preferably 20 ° C. to 80 ° C., particularly preferably 25 ° C. to 60 ° C. Room temperature is more preferred. If the temperature is too low, the removal of soluble components may be insufficient, and if the temperature is too high, the amount of soluble components that can be removed is not greatly affected, and the components of sturgeon eggs may be decomposed. is there.

  The contact time with the sturgeon egg when the soluble component is substantially removed using the organic solvent (A1) is not particularly limited, but is preferably 1 hour to 60 days, more preferably 1 day to 20 days. Particularly preferably, it is 2 days to 10 days. If the time is too short, the soluble components may not be sufficiently removed. If the time is too long, the amount of the components soluble in the solvent can no longer be expected, and the components of the sturgeon egg are decomposed. In some cases.

  The solution obtained by the operation of substantially removing the components soluble in the organic solvent (A1) can also be used as a sturgeon egg extract. This is referred to as “sturgeon egg extract (a1)”. Further, it may be concentrated as necessary to obtain a sturgeon egg extract. The concentration method is not particularly limited, and conventional means may be used. Examples thereof include concentration under reduced pressure using an evaporator and concentration by removing the solvent by heating.

  After substantially removing the components soluble in the organic solvent (A1) as described above, the residue is used in the subsequent extraction operation. The method for separating and removing the residue is not particularly limited, and for example, known methods such as suction filtration, filter press, cylinder press, decanter, centrifuge, and filtration centrifuge can be used. Furthermore, the unnecessary organic solvent (A1) adhering to the residue is preferably distilled off by heating and / or decompression.

  By removing the components soluble in the organic solvent (A1) substantially, oil-soluble components (eg, phospholipids, saturated fatty acids, unsaturated fatty acids, cholesterol, etc.) contained in sturgeon eggs are removed in advance. Therefore, when extracting with the subsequent “water or an organic solvent compatible with water at 30 ° C. in an arbitrary ratio” (B1), the extraction speed and the extraction efficiency are increased, or in the extract by the solvent (B1). Insoluble matter can be reduced. Since there are few impurities, there is also an effect that the operation is easy and the accuracy of the extraction operation is high.

  Specifically, for example, by removing oil-soluble components such as phospholipids, it is possible to suppress permeation obstruction of the solvent (B1) due to the formation of an oil film such as phospholipids. Since sturgeon eggs contain a large amount of phospholipids, extraction in two stages as described above has a particularly remarkable effect of improving extraction efficiency in sturgeon eggs. In addition, by removing oil-soluble components such as phospholipids, insoluble matter (oil-soluble components such as phospholipids) in the solvent (B1) extract can be surely eliminated, and a turbid solvent ( The extract of B1) can be obtained.

  Next, the residue separated and removed in the above is extracted with “an organic solvent compatible with water or water at an arbitrary ratio at 30 ° C.” (B1). The “organic solvent compatible with water or water at an arbitrary ratio at 30 ° C.” (B1) is not particularly limited, and examples thereof include water, monohydric alcohols having 1 to 3 carbon atoms, and polyhydric alcohols. Specific examples include water, methanol, ethanol, 1-propanol, 2-propanol, propylene glycol, 1,3-butylene glycol, 1,2-hexanediol, pentanediol, and glycerin. These are used alone or in combination of two or more. In addition, a case where two or more kinds are mixed to become an “organic solvent compatible with water at an arbitrary ratio at 30 ° C.” is also included. Particularly preferred are water, ethanol, propylene glycol, 1,3-butylene glycol, 1,2-hexanediol, pentanediol, glycerin and the like, and an aqueous solvent usually used for cosmetics is particularly preferred.

  The amount of the solvent (B1) to be used is preferably 0.5 parts by mass to 100 parts by mass, more preferably 1 part by mass to 50 parts by mass with respect to 1 part by mass of the extraction residue (in terms of dry matter), and 2 parts by mass. ˜20 parts by mass is particularly preferred. If the amount of the solvent (B1) used is less than this range, the solvent may not spread or may reach saturation, and extraction may be insufficient. An amount of solvent (B1) exceeding this range may be reduced. Even if it is used, the amount of components soluble in the solvent no longer increases, and only a dilute extract can be produced, or the concentration of solvent removal may increase when concentration is performed.

  The extraction temperature at the time of extraction using the above “water or organic solvent compatible with water at 30 ° C. in an arbitrary ratio” (B1) depends on the boiling point of the solvent used, but preferably 10 ° C. to the solvent thereof. The boiling point at normal pressure is more preferably 20 ° C. to 80 ° C., particularly preferably 25 ° C. to 60 ° C. Room temperature is more preferred. If the extraction temperature is too low, the extraction efficiency may be reduced. If the extraction temperature is too high, the extraction efficiency will not be significantly affected, only the amount of energy used will be increased, and the components of sturgeon eggs will be decomposed. In some cases.

  There is no particular limitation on the extraction time when extraction is performed using the above-mentioned “water or an organic solvent compatible with water at 30 ° C. in any proportion” (B1), but preferably 1 hour to 30 days, more preferably 3 The time is 20 days, and particularly preferably 12 hours to 10 days. If the extraction time is too short, sufficient extraction may not be performed. If the extraction time is too long, an increase in the amount of components soluble in the solvent can no longer be expected, and decomposition of the components of the sturgeon egg may occur.

  Any method such as batch operation, semi-continuous operation, and continuous operation can be used for the extraction operation, and known extraction methods such as immersion extraction and Soxhlet extraction can be used as the extraction method. In addition, the extraction operation is not limited to a single operation, and the extraction solvent can be subjected to an extraction operation by adding fresh solvent (B1) again to the residue after extraction. It is also possible to make it contact.

  After performing the extraction operation with such a solvent (B1), the extraction residue is separated and removed to obtain the target sturgeon egg extract. This is referred to as “sturgeon egg extract (b1)”. The method for separating and removing the residue is not particularly limited, and for example, known methods such as suction filtration, filter press, cylinder press, decanter, centrifuge, and filtration centrifuge can be used.

  Subsequently, the obtained extract may be concentrated as necessary. The concentration method is not particularly limited, and examples thereof include concentration under reduced pressure using an evaporator and concentration by solvent removal by heating.

(Aspect 2)
On the other hand, after substantially removing the components soluble in the solvent using “an organic solvent compatible with water or water at 30 ° C. in an arbitrary ratio” (B2), It is also preferable to extract with an organic solvent (A2) that is not compatible in proportion. The “substantially remove” operation is an operation that substantially removes soluble components by washing, dipping, etc. in the solvent (B2) to be used, and is soluble in the solvent (B2) by the operation. It is preferable to remove substantially all of these components. Thereby, the insoluble matter with respect to the organic solvent (A2) described later is removed. Examples of the operation include the same operations as the soluble component removal operation using the organic solvent (A1) in the first embodiment.

  Examples of the “organic solvent compatible with water or water at an arbitrary ratio at 30 ° C.” (B2) include the same solvents as those described above for the solvent (B1). These are used alone or in combination of two or more. Particularly preferable examples include pure water and physiological saline in that only insoluble components in the organic solvent (A2) described later can be efficiently removed.

  The amount of the solvent (B2) to be used is not particularly limited, but is preferably 0.5 parts by mass to 100 parts by mass and more preferably 1 part by mass to 50 parts by mass with respect to 1 part by mass of the raw sturgeon egg. 2 parts by mass to 20 parts by mass is particularly preferable. If the amount of the solvent (A1) used is less than this range, the solvent may not be distributed over the entire raw material or may reach saturation, which may result in insufficient removal of soluble components, which exceeds this range. Even if the amount of the solvent used is added, the amount of the component soluble in the solvent no longer increases, and when the extract with the organic solvent (A1) is also used, the solvent removal work in the subsequent concentration step is performed. The burden may increase.

  The temperature at which the soluble component is substantially removed using the above “water or an organic solvent compatible with water at 30 ° C. in any proportion” (B2) depends on the boiling point of the solvent used, The temperature in the case of the aspect 1 mentioned is mentioned. When using water as a solvent (B2), Preferably it is 0 to 60 degreeC, More preferably, it is 1 to 50 degreeC, Most preferably, it is 2 to 30 degreeC. 3 degreeC-room temperature is still more preferable. If the temperature is too low, the removal of soluble components may be insufficient, and if the temperature is too high, the amount of soluble components that can be removed is not greatly affected, and the components of sturgeon eggs may be decomposed. is there. In particular, when water is used as the solvent (B2), the components of the sturgeon egg are likely to be decomposed, and therefore it is preferable to keep the temperature range.

  The contact time with the sturgeon egg when the soluble component is substantially removed using the solvent (B2) is not particularly limited, but is preferably 1 hour to 60 days, more preferably 5 hours to 30 days, Particularly preferred is 24 hours to 5 days. If the time is too short, the soluble components may not be sufficiently removed. If the time is too long, the amount of the components soluble in the solvent can no longer be expected, and the components of the sturgeon egg are decomposed. There is a case.

  The solution subjected to the operation of substantially removing the component soluble in the solvent (B2) may be used as a sturgeon egg extract. This is referred to as “sturgeon egg extract (b2)”. Further, it may be concentrated as necessary to obtain a sturgeon egg extract. The concentration method is not particularly limited, and conventional means may be used. Examples thereof include concentration under reduced pressure using an evaporator and concentration by removing the solvent by heating.

  After substantially removing the components soluble in the solvent (B2) as described above, the residue is used in the subsequent extraction operation. The method for separating and removing the residue is not particularly limited, and examples thereof include those described in Aspect 1. Furthermore, the unnecessary solvent (B2) adhering to the residue is preferably distilled off by heating and / or decompression.

  Since the water-soluble components (for example, amino acids, minerals, sugars, low molecular weight proteins, etc.) contained in the sturgeon egg can be removed in advance by the step of substantially removing the components soluble in the solvent (B2), When the subsequent extraction is performed with “an organic solvent that is not compatible with water at an arbitrary ratio at 30 ° C.” (A2), the extraction efficiency can be increased and insoluble matter can be reduced in the organic solvent (A2) extract. Since there are few impurities, there is also an effect that the operation is easy and the accuracy of the extraction operation is high.

  Specifically, for example, by removing water-soluble components such as amino acids, minerals, sugars, and low molecular weight proteins, it is possible to suppress the penetration of the organic solvent (A2). Since sturgeon eggs contain a large amount of the water-soluble components as described above, extraction in two stages as described above has a particularly remarkable effect of improving extraction efficiency in sturgeon eggs. Moreover, by removing water-soluble components, insoluble components (water-soluble components such as amino acids, minerals, sugars, low molecular weight proteins, etc.) in the organic solvent (A2) extract can be surely eliminated, and turbidity An organic solvent (A2) extract without odor can be obtained.

Next, the residue separated and removed above is extracted with “an organic solvent which is not compatible with water at an arbitrary ratio at 30 ° C.” (A2). Although there is no limitation in particular as an organic solvent (A2), Specifically,
Vegetable oils such as olive oil, avocado oil, safflower oil, persic oil, almond oil, sesame oil, rice bran oil, safflower oil, corn oil, rapeseed oil;
Animal oils such as beef tallow and horse oil;
Waxes such as jojoba oil and lanolin;
Hydrocarbons such as squalane and liquid paraffin;
Alcohols such as butanol, benzyl alcohol, lauryl alcohol, myristyl alcohol, cetanol, stearyl alcohol, oleyl alcohol, behenyl alcohol, isostearyl alcohol, octyldodecanol;
Askil glyceryl ethers such as batyl alcohol, chimyl alcohol, ceralkyl alcohol, isostearyl glyceryl ether;
Examples thereof include esters such as isopropyl myristate, glyceryl tri (capryle / caprate), glyceryl tricaprylate, ethyl oleate, isopropyl palmitate and isopropyl isostearate. Of these, preferred is vegetable oil, and particularly preferred is olive oil, safflower oil, safflower oil or corn oil.

  The amount of the organic solvent (A2) to be used is preferably 0.5 parts by mass to 100 parts by mass, more preferably 1 part by mass to 50 parts by mass with respect to 1 part by mass of the extraction residue (in terms of dry matter), and 3 parts by mass.
