Description

TECHNICAL FIELD

[0001] The present application relates to a non-water-soluble pigment composition. BACKGROUND

[0002] As natural pigments, there are a wide variety of red pigments, yellow pigments, and blue pigments, but in recent years, expectations for natural pigments that are considered to be safer have increased due to concerns about synthetic coloring materials being suspected of having problems such as carcinogenicity.

[0003] In addition, there is a strong awareness of sustainable business activities being focused on, and there is a demand for environmentally friendly pigments. Under such circumstances, natural pigments are mostly easily dissolved in water, and thus in the case of being used for cosmetics, food coloring, there are problems of elution into water, and discoloration accompanying the same. In addition, in the case of being used for flexographic printing, there are problems of migration, plate contamination, and the like. Therefore, the current situation is that they are used only in extremely limited uses.

[0004] The inventors investigated documents that describe solutions to the problems of elution and discoloration of natural pigments in water, that is, improvement in water solubility, and as a result, found that there are descriptions of extraction methods of natural pigments, and there are descriptions of oral administration cosmetics, dairy products, pet foods using extracts (Patent Document 1). In addition, there are descriptions of dry mixing of carotenoid pigments with sodium tartrate, alum, and sodium carbonate, and dissolving the mixed powder in water to obtain an aqueous solution for the purpose of stabilizing the color phase (Patent Document 2). In addition, there are descriptions of powder compositions containing carotenoids, oily ingredients, and sugar (Patent Document 3).

[0005] However, these documents do not improve the water solubility of natural pigments. Improvement in the water solubility of natural pigments is a desired challenge.

[0030] Carotenoid pigments are known to include red pigments extracted from carrots, tomatoes, and peppers, and yellow pigments extracted from citrus fruits, gardenias, annatto, and marigolds, and carotenoid pigments are also contained in large amounts in green leafy vegetables.

[0031] Carotenoids are substances belonging to tetraterpenes among terpenes, which are important compounds for plants, and more than 20,000 compounds are known. As carotenoid pigments, hydrocarbon pigments such as β-carotene and lycopene, xanthophyll pigments such as astaxanthin, capsanthin, and lutein, other red pigments, norred, and saffron are known.

[0032] Porphyrin pigments have four pyrrole rings, and their metal complexes are included in chlorophyll, which plays a role in light absorption and light electron movement in photosynthesis, and hematin of hemoglobin, which transports oxygen in blood, and are compounds that play an important role in organisms. Porphyrin metal complexes are known to be used in various ways as light electron functional materials, metal complex catalysts, and molecular conductive materials, and practically exhibit colorful functions by changing peripheral substituents of porphyrin, central metals, and ligands of axial positions.

[0033] Flavonoids are one of the large categories of polyphenols. Flavonoids are a general term for ingredients having a certain chemical structure, are contained in leaves, stems, and trunks of plants, are substances generated by plants to protect the body from the effects of ultraviolet rays, pests, and the like, and become the basis of pigments and bitter ingredients. In addition, flavonoids are classified into flavonols, flavones, catechins, flavanones, anthocyanins, isoflavones, and the like depending on the structure.

[0034] As flavonoid pigments, flavonols, anthocyanin pigments showing various color tones, chalcones, aurones, and the like that develop a deep yellow color can be given.

[0035] (Pigment Proteins)

[0036] Pigment proteins are a general term for proteins that are complexed with pigments in a natural state. They are present in cells and body fluids of animals and plants, and exhibit various color tones and physiological functions through complementary molecular groups containing pigments. Hematin proteins are a combination of iron-porphyrin complex salts and proteins, and the combination ratio of the protein and hematin is 1 to 1, 1 to 2, 1 to 4, and the like. They are widely present in nature, and include hemoglobin, myoglobin, cytochrome, catalase, peroxidase, and the like.

[0037] Metal complexes are a combination of metal complex ions and proteins, and include copper proteins such as hemocyanin and iron proteins such as ferritin. Ferritin is present in the spleen, small intestinal mucosa, liver, and the like, and is believed to participate in the storage of iron in the body and the absorption of iron during digestion.

[0038] Algal pigment proteins are combinations of pyrrole derivatives and proteins, and include phycoerythrin, which exhibits red color in red algae, and phycocyanin, which exhibits blue color in blue-green algae. They are contained in chloroplasts along with chlorophyll and carotenoids, and are considered to be auxiliary pigments for photosynthesis.

[0039] Flavoproteins have flavin mononucleotide or flavin adenine dinucleotide as a complementary molecule group. All of them have an action as an oxidoreductase, and are also called flavin enzymes. There are amino acid oxidase, xanthine oxidase, and the like.

[0040] Carotenoid proteins are combinations of carotenoids and proteins. There are combinations of vitamin A and proteins, and rhodopsin is one of them.

[0041] (Phycocyanin)

[0042] As the pigment protein used in the present application, phycocyanin is most preferable because it exhibits bright blue color. Phycocyanin is a pigment protein, and has phycocyanobilin as a chromophore. Phycocyanin has a structure in which phycocyanobilin is bound to a protein.

[0043] As the phycocyanin of the present application, for example, phycocyanin from blue-green algae, phycocyanin from red algae, phycocyanin from cryptophytes, and the like can be mentioned, and among them, phycocyanin from blue-green algae is preferable from the viewpoint of being able to be collected in a large amount.

[0044] As the blue-green algae, blue-green algae of the genera Spirulina, Arthrospira, ApHanizomenon, Fisherella, Anabaena, Nostoc, Synechocystis, Synechococcus, Tolypothrix, Aphanothece, Mastigoclaus, and Pleurocapsa can be mentioned. Among them, blue-green algae of the genera Spirulina and Arthrospira, which are produced on an industrial scale and whose safety has been confirmed, are preferable, and blue-green algae of the genus Spirulina are more preferable.

[0045] In addition, as the raw material for the production of phycocyanin, fresh blue-green algae can be used, or blue-green algae subjected to drying treatment can be used. As to the dried product of blue-green algae, fresh blue-green algae can be made into a dried product according to a conventional method, or a commercially available dried product can be used.

[0046] Phycocyanin can be obtained, for example, by suspending blue-green algae in a buffer such as water, a phosphate buffer, a citric acid buffer, or the like, and extracting phycocyanin from the blue-green algae.

[0047] As the method for extracting phycocyanin, there is no particular limitation, and a generally known method can be used.

[0048] As a preferred embodiment of the extraction method, for example, the extraction method described in Japanese Patent Application Publication No. 2006-230272 can be cited. Specifically, the extraction method described in the following extraction method (i) can be cited. By this extraction method (i), phycocyanin of high purity and bright color tone can be obtained.

[0049] <Extraction method (i)>

[0050] The extraction method (i) has a first step of extracting phycocyanin in a cyanobacterium into a water suspension to obtain an extract; a second step of reacting a calcium salt and a phosphate salt in the extract to generate calcium phosphate, and causing the calcium phosphate to adsorb an impurity of phycocyanin to obtain an adsorbate; and a third step of removing a residue of the cyanobacterium and the adsorbate from the extract.

[0051] Further, the above extraction method (i) is more preferably the following extraction method (ii).

[0052] <Extraction method (ii)>

[0053] The extraction method (ii) has a first step of extracting phycocyanin in a cyanobacterium into a water suspension to obtain an extract; a second step of reacting a calcium salt and a phosphate salt in the extract to generate calcium phosphate, and causing the calcium phosphate to adsorb an impurity of phycocyanin to obtain an adsorbate; a third step of removing a residue of the cyanobacterium and the adsorbate from the extract; and a step of causing the extract to contain a chelating agent before the third step.

[0054] The phycocyanin used in the present application uses a commercially available product LINABLUE G1 (manufactured by DIC Life Sciences Co., Ltd., trehalose 55%, spirulina extract 40%, trisodium citrate 5%) mixed with a stabilizer. They are used as trehalose for improving thermal stability and citric acid as a pH adjuster as described in Japanese Patent Application Publication No. H11-299450. Note that phycocyanin pigment is contained as a main component in the spirulina extract.

[0055] In the present application, one kind of natural pigment can be used alone, or several kinds of natural pigments can be used at the same time. In order to adjust the color tone to a desired color tone according to the application, the natural pigments can be mixed in advance, and then compounded with the dehydrated condensation compound of a fatty acid and an amino acid and the inorganic material, or the natural pigments, the dehydrated condensation compound of a fatty acid and an amino acid, and the inorganic material can be compounded separately, and then the separately compounded non-water-soluble pigment compositions can be mixed.

[0056] (Dehydrated condensation compound of fatty acid and amino acid)

[0057] A compound produced by dehydrated condensation of a carboxyl group of a fatty acid and an amino group of an amino acid is generally used for a surfactant or the like. The amino acid and the fatty acid are constituent substances of living organisms, and are substances excellent in biodegradability and low in adverse effects on living organisms. Therefore, the dehydrated condensation compound of fatty acid and amino acid produced using these substances as raw materials can be expected to be safe and biodegradable. As the dehydrated condensation compound of fatty acid and amino acid used in the present application, lauroyl lysine, N-octanoyl lysine, or the like is used.

[0058] Lauroyl lysine is an amide compound produced by dehydrated condensation of a carboxyl group of lauric acid and an amino group of lysine, and is a component commonly used in a color cosmetic such as a foundation and a lipstick. It is a safe compound used for the purpose of high transparency, quality texture improvement, and surface treatment. In addition, it has a characteristic of being hardly soluble in solvents and water. However, it is easily soluble in an aqueous alkali solution.

[0059] (Inorganic material)

[0060] Any inorganic material can be used in the present application, but one or more selected from at least boron nitride, titanium oxide, pearl pigment, clay mineral, and hydroxyapatite is preferably used.

[0061] Boron nitride is a solid compound composed of nitrogen and boron, and has a hexagonal crystal system at normal pressure and a cubic crystal system at high pressure, either of which can be used. The hexagonal net surface of the normal pressure boron nitride is overlapped with a large interval, and the interlayer is connected by a weak van der Waals force, so that it easily slides. Therefore, it is also called white graphite. Since the net surface is firm, heat is well transmitted by lattice vibration, and it has the highest thermal conductivity among electrical insulators, and has a low thermal expansion rate, which is about one tenth of that of alumina. As an electrical insulator, it is white because it does not absorb visible light.

[0062] As a general use, it is known to be used in solid lubricants such as ceramics, alloys, resins, and rubbers, mold releasing agents such as a mold for casting an automobile engine and a glass forming mold, and cosmetics as a fine powder.

[0063] Any boron nitride can be used in the present application, and the average particle diameter is preferably 0.1 μm to 100 μm, more preferably 1 μm to 50 μm, and further preferably 5 μm to 30 μm. In addition, the particle diameter is preferably spherical or plate-like.

[0064] (Pearl pigment)

[0065] Pearlescent pigments are substances that exhibit a luster with depth like a pearl by utilizing the multiple reflection and interference phenomenon of light in thin films, and are powders commonly used in the fields of paints and cosmetics. The current mainstream is mica flake particles as a base material, and titanium oxide-coated mica in which fine crystals of titanium oxide are coated on the surface. This titanium oxide-coated mica is highly safe and has stable physical properties, and thus is used in various applications in the fields of cosmetics, paints, inks, plastics, and the like. Recently, new designs of pearlescent pigments have been developed based on the use of synthetic flake base materials and advances in metal oxide coating technology. For example, mica titanium, iron oxide-coated mica titanium, cochineal-coated mica titanium, cochineal-iron blue-coated mica titanium, iron oxide-cochineal-treated mica titanium, iron blue-treated mica titanium, iron oxide-iron blue-treated mica titanium, chromium oxide-treated mica titanium, black titanium oxide-treated mica titanium, acrylic resin-coated aluminum powder, titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, bismuth oxychloride, fish scale foil, and the like can be given.

[0066] (Bismuth oxychloride)

[0067] Bismuth oxychloride is one of pearlescent pigments, and is an inorganic material represented by the chemical formula BiClO. It is obtained by the reaction of bismuth chloride with water, or by mixing bismuth chloride with cadmium oxide and heating. It is developed as a pearlescent pigment that exhibits a pearl luster, and exhibits a color from white to dark yellow. It is odorless and tasteless, and has both crystalline powder and amorphous powder. It has weak light resistance, and is discolored to gray to black by ultraviolet rays and hydrogen sulfide. In general, it is used for the purpose of imparting a pearl luster to cosmetics, and providing a beautiful skin color and expression in makeup cosmetics. Since it has a large specific gravity, it easily settles in a liquid, and thus is suitable for solid products such as lipsticks and eye shadows.

[0068] Any pearlescent pigment can be used in the present application, but a pigment in which titanium oxide is coated on a particle selected from one or more of mica or talc or glass or bismuth oxychloride is preferably used. In addition, the particle diameter is preferably 0.1 to 100 μm, more preferably 1 to 50 μm, and further preferably 5 to 30 μm. In addition, the particle shape is preferably spherical or platy.

[0069] (Titanium oxide)

[0070] Titanium oxide is an oxide of titanium, and is also called titanium dioxide, simple titanium oxide, and titanium dioxide. It is a colorless solid that is naturally produced with rutile (tetragonal system), anatase (tetragonal system), and brookite (orthorhombic system) as main components, and is a metal oxide having a photoelectric effect. The crystal structure is known to be anatase type (tetragonal), rutile type (tetragonal), and brookite type (orthorhombic). As uses, it is used for pigments, colorants, photocatalysts, decomposition of chemicals or microorganisms, offset printing, catalysts, cosmetics such as sunscreens, and dye-sensitized solar cells.

[0071] Any titanium oxide can be used in the present application, and the particle size is preferably 0.1 μm to 100 μm, more preferably 0.1 μm to 50 μm, and further preferably 0.1 μm to 30 μm.

[0072] (Clays)

[0073] A clay mineral is a mineral that constitutes clay, and the main component is a phyllosilicate mineral. Sheets in which metal ions (aluminum, sodium, calcium, etc.) and silicic acid are linked are formed in layers, and water, metal ions, and even organic matter in some cases are easily absorbed and released between the gaps of the sheets, and thus the clay mineral is utilized as a functional material such as a humidity adjusting material, an ion exchange material, a catalyst, and the like in various fields including household goods. In addition, the clay mineral is used as a raw material for ceramic materials and pottery.

[0074] As the clay mineral used in the present application, bentonite, hectorite, montmorillonite, kaolinite (kaolin), montmorillonite, sericite, illite, glauconite, chlorite, talc, and zeolite can be mentioned.

[0075] Among these, bentonite, hectorite, and montmorillonite are preferred as the clay mineral of the present application because of their high affinity for pigments, high non-water-solubility, and excellent color development.

[0076] Bentonite, hectorite, and montmorillonite have a negative charge in the crystal phase. Cations that offset the charge are held between the layers of the sheet structure, and the layers are expanded with respect to the thickness of the sheets.

[0077] The so-called organically treated treatment is a treatment in which the metal cations contained in the clay mineral are replaced with organic cations having hydrophobicity. The surfaces of organically treated bentonite, organically treated hectorite, and organically treated montmorillonite become hydrophobic, respectively, and thus the hydrophobic interaction with the hydrophobic sites in the chemical structures of natural pigments such as redwood pigments, chlorophyll pigments, safflower yellow pigments, and phycocyanin pigments is strengthened, and the pigments are easily adsorbed. From the viewpoint of the ease of adsorption of pigments and the amount of adsorption, organically treated clay minerals are preferably used in the present application.

[0078] The particle size of the clay mineral used is preferably 0.1 μm to 100 μm, more preferably 1 μm to 50 μm, and further preferably 5 μm to 30 μm.

[0079] (Hydroxyapatite)

[0080] The hydroxyapatite used in the present application is one of calcium phosphates, and is a main component of teeth and bone. The hydroxyapatite, which exists as a mineral and a component of organisms in nature, is widely used as a synthetic component in medical devices, dental materials, such as a coating of an implant, a bone-forming material, an artificial tooth root, and the like, because of its high affinity for organisms. In addition, the hydroxyapatite has a unique property of maintaining its crystal structure even if a part of ions in the crystal is replaced. As a result, by subtly controlling the ions in the crystal and the crystal shape, various functions such as selective adsorption of proteins, appearance of catalytic function, and the like can be obtained, and thus the hydroxyapatite is widely used in the field of chemical industry.

[0081] The particle diameter of the hydroxyapatite used is preferably 0.1 μm to 100 μm, more preferably 1 μm to 50 μm, and further preferably 5 μm to 30 μm.

[0082] (non-water-soluble pigment composition)

[0083] The natural pigment used in the present application is mostly in the form of a dye, and thus is water-soluble. However, in the present application, it has been found that the natural pigment, the dehydration condensation compound of fatty acid and amino acid, and the inorganic material are complexed by the action modes of coating, impregnation, and adsorption, and thus are not dissolved in water as a non-water-soluble pigment composition. The complexing in the present application is not limited to the action modes of coating, impregnation, and adsorption, and is defined as not a simple mixture, but a state in which the natural pigment, the dehydration condensation compound of fatty acid and amino acid, and the inorganic material interact with each other by physical adsorption or chemical adsorption, and thus the non-water-solubility is achieved.

[0084] In the case where the complexing is performed using only the inorganic material and the natural pigment, the amount of the natural pigment adsorbed is small because the interaction between the inorganic material and the natural pigment is weak, and thus the color development is insufficient. On the other hand, the natural pigment and the dehydration condensation compound of fatty acid and amino acid strongly interact, and thus a large amount of the natural pigment can be adsorbed. Furthermore, the dehydration condensation compound of fatty acid and amino acid is adsorbed on the surface of the inorganic material, and thus a non-water-soluble pigment composition having properties derived from the color development of the natural pigment, the smooth touch of the dehydration condensation compound of fatty acid and amino acid, and the concealability of the inorganic material can be obtained.

[0085] The non-water-soluble colorant obtained by the present application can improve the resistance of natural colorants to be used as coloring materials equivalent to general pigments to applications such as coating materials or printed marks for food, cosmetics, pharmaceuticals, or agricultural chemicals, stationery, writing instruments, printing inks, inkjet inks, metallic inks, paints, plastic colorants, color toners, fluorescent marking agents, fluorescent probes, or chemical sensors. In addition, the non-water-soluble colorant composition of the present application can also improve heat resistance, light resistance, and the like. Note that the applications of the non-water-soluble colorant composition of the present application are not limited to the above-mentioned applications.

[0086] The composition of the natural colorant, the dehydration condensation compound of a fatty acid and an amino acid, and the inorganic material in the non-water-soluble colorant composition of the present application is not particularly limited, and the composition is preferably set to a range of 0.1% to 90% of the natural colorant, 1% to 70% of the dehydration condensation compound of a fatty acid and an amino acid, and 15% to 90% of the inorganic material in terms of mass ratio, and the total is 100%. More preferably, the composition is set to a range of 0.1% to 70% of the natural colorant, 5% to 60% of the dehydration condensation compound of a fatty acid and an amino acid, and 30% to 80% of the inorganic material, and further preferably, the composition is set to a range of 1% to 40% of the natural colorant, 10% to 50% of the dehydration condensation compound of a fatty acid and an amino acid, and 40% to 60% of the inorganic material.

[0087] The average particle diameter of the non-water-soluble colorant composition of the present application is preferably 0.1 μm to 100 μm, and more preferably 1 μm to 50 μm.

[0088] The content of the element derived from the inorganic material used in the non-water-soluble colorant composition of the present application is preferably 90% or less, and more preferably 80% or less, compared to the inorganic material itself.

[0089] (Method for producing non-water-soluble colorant composition)

[0090] As the method for producing the non-water-soluble colorant composition of the present application, there are a method (Method 1) in which a natural colorant, a dehydration condensation compound of a fatty acid and an amino acid, and an inorganic material are mixed in a solvent and a non-water-soluble colorant composition is obtained by wet processing, and a method (Method 2) in which a natural colorant, a dehydration condensation compound of a fatty acid and an amino acid are mixed in a solvent, a complexed composition of the natural colorant, the dehydration condensation compound of a fatty acid and an amino acid obtained by wet processing is complexed with an inorganic material by dry processing.

[0091] (Method 1: complexation using wet processing)

[0092] As a method of obtaining a non-water-soluble pigment composition by mixing a natural pigment, a dehydrated condensation compound of a fatty acid and an amino acid, and an inorganic material in a solvent, 1) a dispersion liquid or a solution of the dehydrated condensation compound of the fatty acid and the amino acid is prepared. The solution is prepared by dissolving the dehydrated condensation compound of the fatty acid and the amino acid using sodium hydroxide or the like. As for the dispersion liquid, the dehydrated condensation compound of the fatty acid and the amino acid can be dispersed in the solvent, or can be prepared by re-precipitating the dehydrated condensation compound of the fatty acid and the amino acid by pH adjustment of the solution. 2) On the other hand, the natural pigment is dissolved in a solvent, and a natural pigment solution is prepared. 3) A dispersion liquid of the inorganic material is adjusted. In preparing the dispersion liquid or the solution of 1 to 3, an alcohol can be used, or a mixed solvent of water and an alcohol can be used. 4) The dispersion liquid or the solution of the dehydrated condensation compound of the fatty acid and the amino acid and the natural pigment solution are added to the dispersion solution of the inorganic material, and mixed, and a non-water-soluble pigment composition is prepared, but the mixing method, the order of mixing of the dispersion liquid or the solution of the dehydrated condensation compound of the fatty acid and the amino acid, the natural pigment solution, and the dispersion liquid of the inorganic material, and the order of mixing can be performed in any method and order. The temperature of the mixing can be room temperature or heating and mixing. The pH of each dispersion liquid or solution at the time of the mixing is adjusted in consideration of the decomposition temperature of the natural pigment monomer. 5) The pH of the mixed solution is adjusted, and the natural pigment, the dehydrated condensation compound of the fatty acid and the amino acid, and the inorganic material are complexed, and a non-water-soluble pigment composition is prepared.

[0093] The obtained mixed solution is filtered and dried, and a non-water-soluble pigment composition can be obtained. When the mixed solution is filtered using a filter such as a Nutsche filter (a high-pressure vacuum filter), a wet cake colored with the natural pigment is obtained on a filter paper, and thus it can be confirmed that the natural pigment, the dehydrated condensation compound of the fatty acid and the amino acid, and the inorganic material are complexed. In addition, when water washing of the wet cake of the non-water-soluble pigment composition is repeated, the filtrate becomes colorless and transparent, and it can be confirmed that the pigment component does not flow out. The obtained non-water-soluble pigment composition in the form of a water-containing wet cake can be dried by room temperature, heating, vacuum, reduced pressure, and the like, and a dried non-water-soluble pigment composition can be obtained. The drying method and the drying machine can be any method and device as long as they are a general method and device, and are not limited.

[0094] (Method 2: Complexation using wet processing and dry processing)

[0095] The method of dry compounding a complexed composition of a natural pigment and a dehydration condensation compound of a fatty acid and an amino acid obtained by mixing the natural pigment and the dehydration condensation compound of a fatty acid and an amino acid in a solvent with an inorganic material, 1) first, a dispersion liquid or a solution of the dehydration condensation compound of a fatty acid and an amino acid is prepared. The solution is prepared by dissolving the dehydration condensation compound of a fatty acid and an amino acid with an aqueous sodium hydroxide solution or the like. As for the dispersion liquid, the dehydration condensation compound of a fatty acid and an amino acid can be dispersed in water, or can be prepared by re-precipitating the dehydration condensation compound of a fatty acid and an amino acid by pH adjustment of the solution. 2) On the other hand, a natural pigment is dissolved in a solvent to prepare a natural pigment solution. In preparing the dispersion liquid or the solution of 1 and 2, an alcohol can be used, or a mixed solvent of water and an alcohol can be used. 3) Next, the above two liquids are mixed to prepare a non-water-soluble pigment composition, but the natural pigment solution can also be mixed in the dispersion liquid or the solution of the dehydration condensation compound of a fatty acid and an amino acid, or conversely, the dispersion liquid or the solution of the dehydration condensation compound of a fatty acid and an amino acid can be mixed in the natural pigment solution, or the two liquids can be mixed in small amounts each time while being prepared. The temperature of the mixing can be room temperature or heating and mixing. The mixing temperature is preferably 10 to 60°C, and more preferably 20 to 50°C, taking into account the decomposition temperature of the natural pigment monomer. The pH of each dispersion liquid or solution at the time of mixing is adjusted taking into account the decomposition of the natural pigment. 4) The pH of the mixed liquid is adjusted to complex the natural pigment and the dehydration condensation compound of a fatty acid and an amino acid, and a non-water-soluble pigment composition is prepared.

[0096] The obtained mixed liquid is filtered and dried to obtain a complexed composition of a natural pigment and a dehydration condensation compound of a fatty acid and an amino acid. When the mixed liquid is filtered using a filter such as a Nutsche filter, a wet cake colored with a natural pigment is obtained on the filter paper, so it can be confirmed that complexation of the natural pigment and the dehydration condensation compound of a fatty acid and an amino acid has occurred. In addition, if the wet cake of the complexed composition of a natural pigment and a dehydration condensation compound of a fatty acid and an amino acid is repeatedly washed with water, the filtrate becomes colorless and transparent, and it can be confirmed that the pigment component does not flow out. The obtained complexed composition of a natural pigment and a dehydration condensation compound of a fatty acid and an amino acid, which is a wet cake containing water, can be dried by room temperature or heating, vacuum, reduced pressure drying, or the like, to obtain a dried complexed composition of a natural pigment and a dehydration condensation compound of a fatty acid and an amino acid. The drying method and the drying machine can be any method, and are not limited as long as they are general methods and devices.
