The present invention relates to a mineral-containing composition for use in the production of an ice that can be added to water or drink to improve the flavor thereof. Furthermore, the present invention relates to an ice having such a function, and to a method of producing the ice.
Against a background of growing health-consciousness and taste-consciousness in recent years, the societal concern to seek safe and good-tasting water has been growing, and mineral water contained in a container such as a PET bottle is a very popular drink all over the world. However, garbage of plastic containers such as PET bottles is posing a serious environmental problem, and accordingly, mineral water that can be served conveniently for household use or the like is under development to replace bottled mineral water. However, tap water contains chlorine for sterilization, and thus, the chlorine remaining in the water causes a chlorine smell, impairing the flavor of the water markedly.
What is under development is, for example, a potable water in the form of purified water supplemented with a high concentration of mineral or the like for the purpose of resupplying mineral components that are trace elements necessary for the physiological action of an organism. For example, PTL 1 discloses a potable water containing a high concentration of magnesium, wherein the potable water is produced by mixing purified water with a liquid concentrate containing a large amount of magnesium. PTL 2 discloses a method of producing a drink, wherein mineral components including magnesium and calcium are added to water derived from deep-sea water. However, it is known that divalent metal ions give odd tastes such as bitterness and acridity. Water, food, or drink that contains these minerals at high concentrations has the drawback of being difficult to ingest.
Furthermore, PTL 3 discloses a method of producing mineral water characterized in that immersing natural one such as granite porphyry, tenju stone, or tourmaline in water causes mineral components to be eluted, but the method has drawbacks in that the resulting mineral water contains undesired components such as vanadium that is regarded as harmful if ingested excessively, and in that the efficiency of extraction of minerals is not high. In addition, PTL 4 discloses a method of producing mineral water, wherein chicken dropping charcoal is heated with water for extraction, but chicken dropping charcoal is not suitable as a raw material for use in food applications.
PTL 5 discloses a method of producing mineral water, wherein bamboo charcoal is boiled for extraction, and in addition, PTL 6 discloses a method of producing alkaline water, wherein charcoal is boiled for extraction. However, these methods disclosed in the conventional technologies do not make it possible to extract mineral components efficiently to thereby give a mineral water containing desired mineral components.
PTL 7 discloses a method of making gradated charcoal ice, wherein potable water and pulverized charcoal are mixed suitably. However, there has hitherto been no known method of producing an ice that not only tastes good by itself but also can be added to water or drink to improve the flavor thereof.
An object of the present invention is to provide an ice that not only tastes good by itself but also can be added to water or drink to improve the flavor thereof.
The present inventors have just recently discovered the use of activated carbon of a plant-derived raw material, such as palm shell activated carbon, as a natural material from which a. mineral can be eluted using pure water, have vigorously made a study on the extraction conditions, and as a result, have succeeded in easily and efficiently producing a liquid mineral extract containing an abundant amount of potassium that is a mineral component extremely important for humans. In addition, the present inventors have discovered that the liquid mineral extract and a liquid mineral concentrate given by concentrating the extract not only contain an abundant amount of potassium as a mineral component but also have a significantly small amount of divalent metal ions and chloride ions that give odd tastes such as bitterness and acridity. Furthermore, the present inventors have vigorously made a study on the components of a liquid mineral extract thus produced, and as a result, have made a surprising discovery not only that that a mineral-containing composition containing such a composition gives, to water containing the composition added thereto, a significant buffer capacity in the pH range of from weak alkalinity to weak acidity and besides a mild and less odd flavor but also that freezing an aqueous solvent containing the mineral-containing composition added thereto makes it possible to make good-tasting ice, and in addition, that the ice thus produced itself has a function for improving the flavor of water or drink.
In other words, a main object of the present invention consists in the following.
The method according to 9 or 10, wherein, when the drink is an alcoholic drink, the mineral-containing composition is added to the aqueous solvent in such a manner that the concentration of potassium ions added is 50 ppm to 500 ppm.
The ice according to 12, comprising an aqueous solvent selected from tap water, purified water, pure water, and natural water.
The ice according to 12 or 13, wherein, when the drink is an alcoholic drink, the ice contains potassium ions at 50 ppm to 500 ppm in terms of the concentration of potassium ions added.
The present invention can easily provide an ice that not only is good-tasting but also can itself improve the flavor of water or drink.
The present invention relates to a mineral-containing composition for use in the production of an ice for improving the flavor of water or drink, the mineral-containing composition comprising potassium ions the concentration of which is the highest of the metal ions present in the mineral-containing composition.
In cases where ice is made in a refrigerator in a house, it is generally recommended to use tap water as an aqueous solvent for the purpose of preventing the rot of water by virtue of the bactericidal effect of chlorine contained in the tap water. However, tap water contains sodium hypochlorite, calcium hypochlorite, liquid chlorine, and the like mixed therein for sterilization.
The Waterworks Law of japan provides that the residual chlorine shall be kept at 0.1 mg or more per liter (=3×10−5 mol/l) at a faucet in each house. However, ammonia nitrogen contained in the raw water of the tap water reacts with residual chlorines such as hypochlorite (HCLO) molecules to form inorganic chloramines (monochloramine, dichloramine, and trichloramine), which become the main cause of the chlorine smell, and impair the flavor of the water. The present inventors have just recently made a surprising discovery that a mineral-containing composition according to the present invention gives, to water containing the mineral-containing composition added thereto, a significant buffer capacity in the pH range of from weak alkalinity to weak acidity, and besides, decreases the chlorine smell of the water to improve the flavor thereof. It is conceivable that, since HCLO in water at a pH of 7.5 or more is ionized to CLO−, the water made weakly alkaline by addition of a mineral-containing composition according to the present invention is less likely to cause inorganic chloramines to be formed in the water, thus decreasing the generation of the chlorine smell. Freezing such a water makes it possible to easily obtain, in a house, ice having a flavor improved by a decrease in the chlorine smell.
Furthermore, the present inventors have made a surprising discovery that the ice thus produced has a function for improving the flavor of water or drink.
Potassium is one of the minerals necessary for an organism, and the majority, of the potassium in an Organism is present in the cells. The potassium interacts with a large amount of sodium present in the .extracellular fluid, and thus plays an important role in maintaining the osmotic pressure of the cell and holding water in the cell. Potassium, together with sodium, maintains the osmotic pressure of the cell, and besides, serves for functions such as the maintenance of acid-base equilibrium the innervation, the regulation of the cardiac function and the muscular function, and the regulation of the enzymatic reaction in the cell. In addition, it is known that potassium inhibits the reabsorption of sodium in the kidney, facilitates the excretion into urine, and thus, has the effect of decreasing the blood pressure. As above-mentioned, potassium is a mineral component extremely important for humans, but an excessive amount of potassium ions give odd tastes such as bitterness and acridity. Accordingly, a mineral-containing composition according to the present invention is preferably prepared in such a manner that the concentration of potassium added to the ice is optimal in accordance with the object (that is, water or drink) intended to have an improved flavor.
A mineral-containing composition according to the present invention may further comprise chloride ions, calcium ions, magnesium ions, sodium ions, iron ions, zinc ions, silicon ions, and/or sulfate ions besides potassium ions.
Naturally-occurring water contains a given amount of chloride ions, and many of the ions are derived from natural soil or sea water. Chloride ions, if present at 250 to 400 mg/l or more, give a taste salty for a taste-sensitive person, and can impair the taste, and hence, the amount of chloride ions contained in a mineral-containing composition according to the present invention is preferably as small as possible. The amount of chloride ions contained in a mineral-containing composition according to the present invention may be, for example, 50% or less, 49% or less, 48% or less, 47% or less, 46% or less, 45% or less, 44% or less, 43% or less, 42% or less, 41%. or less, 40% or less, 39% or less, 38% or less, 37% or less, 36% or less, 35% or less, 34% or less, 33% or less, 32% or less, 31% or less, 30% or less, 29% or less, 28% or less, 27% or less, 26% or less, 25% or less, 24% or less, 23% or less, 22% or less, 21% or less, 20% or less, 19%. or less, 18% or less, 17% or less, 16% or less, 15% or less, 14% or less, 13% or less, 12% or less, 11% or less, 10% or less, 9% or less, .8′33 or less, 7% or less, 6% or less, 5% or less, 4% or less, 3% or less, 2% or less, or 1% or less of the above-mentioned potassium ion concentration.
It is known that calcium together with phosphorus, in the than of hydroxyapatite, is skeletogenous in an organism, and participates in muscle contraction. It is known that magnesium participates in osteogenesis, odontogenesis, many intracorporeal enzymatic reactions, and energy production in an organism. In addition, it is know n that the amount of calcium ions and magnesium ions contained in water influences the taste. The index (hardness) as the total amount of calcium and magnesium contained in the minerals contained in water is smaller for what is termed soft water than a given level, and larger for what is termed Lard water. In general, more of the mineral water produced domestically in Japan is soft water, and more of the mineral water produced in Europe is hard water. According to the criteria stipulated by WHO, the U.S. hardness (mg/l in terms of calcium carbonate converted from the amount of these salts is 0 to 60 for what is termed soft water, 120 to 180 for what is termed hard water, and 180 or more for what is termed very hard water. In general, water having a suitable hardness (10 to 100 mg/l) is regarded as good-tasting. Water containing a higher amount of magnesium in particular is bitterer, and more difficult to drink. In addition, a higher hardness not only influences the taste, but also stimulates the stomach and intestines, causes diarrhea or the like, and hence, is not preferable. The amount of calcium ions contained in a mineral-containing composition according to the present invention may be, for example, 2.0% or less, 1.9% or less, 1.8% or less, 1.7% or less, 1.6% or less, 1.5% or less, 1.4% or less, 1.3% or less, 1.2% or less, 1.1% or less, 1.0% or less, 0.9% or less, 0.8% or less, 0.7% or less, 0.6% or less, 0.5% or less, 0.4% or less, 0.3% or less, 0.2% or less, 0.1% or less, 0.09% or less, 0.08% or less, 0.07% or less, 0.06% or less, 0.05% or less, 0.04% or less, 0.03% or less, 0.02% or less, or 0.01% or less of the potassium ion concentration. In addition, the amount of magnesium ions contained in a mineral-containing composition according to the present invention may be, for example, 1.0% or less, 0.9% or less, 0.8% or less, 0.7% or less, 0.6% or less, 0.5% or less, 0.4% or less, 0.3% or less, 0.2% or less, 0.1% or less, 0.09% or less, 0.08% or less, 0.07% or less, 0.06% or less, 0.05% or less, 0.04% or less, 0.03% or less, 0.02% or less, or 0.01% or less of the potassium ion. concentration.
Sodium holds water in an organism, maintaining the amount of the extracellular fluid and the amount of the circulating blood, and regulating the blood pressure. It is known that the ingestion of a given amount of sodium ions is good for effective intracorporeal rehydration, and efficacious as the countermeasures particularly against heat stroke or the like. However, excessive ingestion of sodium increases the amount of such a liquid, and thus, will undesirably raise the blood pressure, and cause dropsy. In addition, a higher amount of sodium ions give a saltier taste and a slimier feeling, and impairs the refreshing taste of a drink in some cases. The amount of sodium contained in the mineral-containing composition according to the present invention may be, for example, 5 to 45%, 5 to 40%, 5 to 35%, 5 to 30%, 5 to 25%, 5 to 20%, 5 to 15%, 5 to 10%, 10 to 45%, 10 to 40%, 10 to 35%, 10 to 30% 10 to 25%, 10 to 20%, 10 to 15%, 15 to 45%, 15 to 40%, 15 to 35%, 15 to 30%, 15 to 25%, 15 to 20%, 20 to 45%, 20 to 40%, 20 to 35%, 20 to 30%, 20 to 25%, 25 to 50%, 25 to 45%, 25 to 40%, 25 to 35%, 25 to 30%, 30 to 45%, 30 to 40%, 30 to 35%, 35 to 45%, 35 to 40%, or 40 to 45% of the potassium ion concentration.
A mineral-containing composition according to the present invention can be produced from an activated carbon extract of a plant-derived raw material. Activated carbon is a porous substance composed largely of carbon and additionally of oxygen, hydrogen, calcium, and the like, has a large surface area per volume, and thus, has the property of adsorbing many substances, and hence, is widely produced industrially from the early twentieth century to now. In general, activated carbon is produced by generating (activating) the nm-level micropores inside a carbon material serving as a raw material. Methods of producing activated carbon is generally classified into the following: a gas activation method in which a raw material is carbonized, and then, the resulting product is activated at high temperature using an activation gas such as water vapor or carbon dioxide; and a chemical agent activation method in which a chemical agent such as zinc chloride or phosphoric acid is added to a raw material, and then, the resulting mixture is carbonized and activated at once under heating in an inert gas atmosphere (NPL 1). Activated carbon to be used in the present invention can be produced by one of the above-mentioned gas activation method and the chemical agent activation method, using a plant-derived raw material as a carbon material.
A raw material for activated carbon to be used in the present invention is subject to no particular limitation as long as the raw material is plant-derived. Examples of such a raw material include: fruit shells (coconut palms, palms, almonds, walnuts, and plums); woods (sawdust, charcoal, resins, and sawdust ash (carbide of sawdust); bamboos; food residues (bagasse, chaff, coffee beans, and molasses); wastes (pulp mill waste liquids and construction and demolition wastes); and the like. Such a raw material is typically selected from palm shells, sawdust, bamboos, and combinations thereof, and is suitably palm shells. A palm shell means a hard part—called a shell—in a fruit of a coconut palm or a palm.
The shape of activated carbon to be used in the present invention is subject to no particular limitation. Examples of the activated carbon include powdery activated carbon, particulate activated carbon (crushed carbon, granular carbon, and molded carbon), fibrous activated carbon, specially molded activated carbon, and the like.
A step of extracting minerals from activated carbon of a plant-derived raw material using an, aqueous solvent is performed by bringing activated carbon of a plant-derived raw material in contact with an aqueous solvent, and eluting minerals from activated carbon of a plant-derived raw material. Such a step is subject to iso particular limitation as long as the step makes it possible to elute minerals from activated carbon of a plant-derived raw material. For example, such a step can be performed by immersing activated carbon of a plant-derived raw material in an aqueous solvent, or allowing an aqueous solvent to pass through a column packed with activated carbon of a plant-derived raw material. In cases where activated carbon of a plant-derived raw material is immersed in an aqueous solvent, the aqueous solvent may be stirred to increase the efficiency of extraction. To remove impurities from a liquid given by extracting minerals from the activated carbon of a plant-derived raw material using an aqueous solvent, a method of producing a liquid mineral extract according to the present invention may further include a step of centrifuging the resulting liquid extract, a step of filtrating the liquid extract, and/or the like.
An aqueous solvent to be used in a step of extracting minerals from activated carbon of a plant-derived raw material using an aqueous solvent basically refers to an aqueous solvent other than an HCl solution. Such a solvent is typically an aqueous solvent, and is particularly preferably pure water. Pure water means high-purity water containing no or few impurities such as salts, residual chlorine, insoluble microparticles, organic substances, and nonelectrolytic gas. Pure water encompasses RO water (water passed through a reverse osmosis membrane) deionized water (water from which ions have been removed with an ion exchange resin or the like), distilled water (water distilled with a distiller), and the like, which differ in the method of removing impurities. Pure water contains no mineral component, and hence, does not exhibit any effect of resupplying minerals.
The extraction temperature is subject to no particular limitation as long as the temperature makes it possible to extract minerals from activated carbon of a plant-derived raw material using an aqueous solvent. The step of extracting minerals from activated carbon of a plant-derived raw material using an aqueous solvent can be performed at a temperature of 5° C. or more, 10° C. or more. 15° C. or more, 20° C. or more 25° C. or more, 30° C. or more, 35° C. or more, 40° C. or more, 45° C, or more, 50° C. or more, 55° C. or more, 60° C. or more, 65° C. or more, 70° C. or more, 75° C. or more, 80° C. or more, 85° C. or more, 90° C. or more, or 95° C. or more, and is performed, for example at a temperature of 5 to 95° C., 5 to 90° C., 5 to 85° C., 5 to 80° C., 5 to 75° C., 5 to 70° C., 5 to 65° C. 5 to 60° C., 5 to 55° C., 5 to 50° C., 5 to 45° C., 5 to 40° C., 5 to 35° C., 5 to 30° C. 5 to 25° C., 5 to 20° C. 5 to 15° C., 5 to 10° C., 10 to 95° C., 10 to 90° C., 10 to 85° C., 10 to 80° C., 10 to 75° C., 10 to 70° C., 10 to 65° C., 10 to 60° C., 10 to 55° C., 10 to 50° C., 10 to 45° C., 10 to 40° C., 10 to 35° C., 10 to 30° C., 10 to 25° C., 10 to 20° C., 10 to 15° C., 15 to 95° C., 15 to 90° C., 15 to 85° C., 15 to 80° C., 15 to 75° C., 15 to 70° C., 15 to 65° C., 15 to 60° C., 15 to 55° C., 15 to 50° C., 15 to 45° C., 15 to 40° C., 15 to 35° C., 15 to 30° C., 15 to 25° C., 15 to 2.0° C., 20 to 95° C., 20 to 90° C., 20 to 85° C., 20 to 80° C., 20 to 75° C., 20 to 70° C., 20 to 65° C., 20 to 60° C., 20 to 55° C., 20 to 50° C., 20 to 45° C., 20 to 40° C., 20 to 35° C., 20 to 30° C., 20 to 25° C., 25 to 95° C., 25 to 90° C., 25 to 85° C., 25 to 80″C, 25 to 75° C., 25 to 70° C., 25 to 65° C., 25 to 60° C., 25 to 55° C., 25 to 50° C., 25 to 45° C., 25 to 40° C., 25 to 35° C., 25 to 30° C., 30 to 9.5° C., 30 to 90° C., 30 to 85° C., 30 to 80° C., 30 to 75° C., 30 to 70° C., 30 to 65° C., 30 to 60° C., 30 to 55° C., 30 to 50° C., 30 to 45° C., 30 to 40° C., 30 to 35° C., 35 to 95° C., 35 to 90° C., 35 to 85° C., 35 to 80° C., 35 to 75° C., 35 to 70° C., 35 to 65° C., 35 to 60° C., 35 to 55° C., 35 to 50° C., 35 to 45° C., 35 to 40° C., 40 to 95° C., 40 to 90° C., 40 to 85° C., 40 to 80° C., 40 to 75° C., 40 to 70° C., 40 to 65° C., 40 to 60° C., 40 to 55° C., 40 to 50° C., 40 to 45° C., 45 to 95° C., 45 to 90° C., 45 to 85° C., 45 to 80° C., 45 to 75° C., 45 to 70° C., 45 to 65° C., 45 to 60° C., 45 to 55° C., 45 to 50° C., 50 to 95° C., 50 to 90° C., 50 to 85° C., 50 to 80° C., 50 to 75° C., 50 to 70° C., 50 to 65° C., 50 to 60° C., 50 to 55° C., 55 to 95° C., 55 to 90° C., 55 to 85° C., 55 to 80° C., 55 to 75° C., 55 to 70° C., 55 to 65° C., 55 to 60° C., 60 to 95° C., 60 to 90° C., 60 to 85° C., 60 to 80° C., 60 to 75° C., 6.0 to 70° C., 60 to 65° C., 65 to 95° C., 65 to 90° C., 65 to 85° C., 65 to 80° C., 65 to 5° C., 65 to 70° C., 70 to 95° C., 70 to 90° C., 70 to 85° C., 70 to 80° C., 70 to 75° C., 75 to 95° C., 75 to 90° C., 75 to 85° C., 75 to 80° C., 80 to 95° C., 80 to 90° C., 80 to 85° C., 85 to 9.5° C., 85 to 90° C., or 90 to 95° C.

A liquid extract thus produced can be concentrated using a method known in the art. Examples of such a method include boiling concentration, vacuum concentration, freeze concentration, membrane concentration, ultrasonic humidification separation, and the like. Concentrating a liquid mineral extract makes it possible to obtain a liquid mineral concentrate composition containing a desired mineral such as high-concentration potassium almost without changing the composition of the liquid.
A container for providing a mineral-containing composition according to the present invention is not limited to any particular form. Examples of the form include: metal containers (cans); resin containers such as of a dropping type, spray type, dropper type, or lotion bottle type; paper containers (including paper containers with a gable top); PET bottles; pouch containers; glass bottles; airless containers; portion containers; antiseptic-free (PF) eyedrop containers; stick packs; small pump containers; large pump containers; portion cup containers; inner package-containing bottles; single-use plastic containers; water-soluble film containers; and the like.
A mineral-containing composition according to the present invention can be added to an aqueous solvent in such a manner that the concentration of each mineral component is within the above-mentioned range. Then, the aqueous solvent containing the added mineral-containing composition is frozen, whereby it is made possible to produce an ice that tastes good, and in addition, can improve the flavor of water or drink. Ice making is subject to no particular limitation, and can be performed using any technique conventional in the art.
The aqueous solvent is subject to no particular limitation as long as the aqueous solvent is potable water, and is typically tap water, purified water, pure water, or natural water.
Water the flavor of which is improved by the addition of an ice according to the present invention is subject to no particular limitation, and is typically tap water, purified water, or natural water.
A drink the flavor of which is improved by the addition of an ice according to the present invention is subject to no particular limitation. Typical examples of such a drink include alcoholic drinks, nonalcoholic drinks, carbonated chinks (nonflavored carbonated drinks, flavored carbonated chinks, and the like), fruit drinks (natural fruit juices, fruit juice drinks, fruit flesh drinks, fruit-juice-containing blended chinks, fruit-juice-containing carbonated drinks, juice-based near water, ades, and the like), coffee drinks, tea drinks (green tea drinks, black tea drinks, blended tea drinks, Oolong tea drinks, barley tea drinks, and the like), vegetable drinks, sports drinks, and milky drinks. In the invention, examples of the drinks include not only ready-to-drink drinks directly drinkable after purchase but also drink bases and raw alcoholic drinks. A drink base means a drink that is suitably diluted to be drunk, and examples of the drink base include drinks for cocktail preparation, concentrated types of drinks, and the like. In addition. a raw alcoholic drink means an alcoholic material that serves as a raw material to be blended in an alcoholic drink.
In the present invention, the alcohol content of an alcoholic drink or a raw alcoholic drink is subject to no particular limitation as long as the alcoholic drink or raw alcoholic material contains ethanol as an alcohol component. The content is typically 1 v/v% or more.
The raw alcoholic material for an alcoholic chink or raw alcoholic drink is subject to no particular limitation. Examples of the raw alcoholic material include spirits (rums, vodkas, gins, and the like), whiskeys, brandies, and Japanese distilled spirits, and further include brewages (beers, sakes, fruit alcoholic materials, and the like), sparkling alcoholic materials, and mixed alcoholic materials (synthetic sakes, sweet fruit alcoholic materials, liqueurs, and the like). These raw alcoholic materials can be used alone or in combination.
In addition, such an alcoholic drink may have fruit juice blended therein. The fruit juice is not limited to any particular kind. Examples of the fruit juice include citrus pines (orange juices, mandarin orange juices, grapefruit juices, lemon juices, lime juices, and the like), apple juices, grape juices, peach juices, tropical fruit juices (pineapple, guava, banana, mango, acerola, papaya, passion fruit, and the like), other fruit juices (Japanese apricot juices, pear juices, apricot juices, plum juices, berry juices, kiwi fruit juices, and the like), tomato juices carrot juices, strawberry juices, melon juices, and the like.
As above-mentioned, it is preferable to make an adjustment in such a manner that the concentration of potassium added to an aqueous solvent is optimal in accordance with the object (that is, water or drink) intended to have an improved flavor. For example, in cases where the drink is an alcoholic drink, a mineral-containing composition according to the present invention can be prepared in such a manner that the concentration of potassium ions added (the potassium concentration of the mineral-containing composition (ppm)/the dilution ratio) is, for example, 50 to 500 ppm, 50 to 490 ppm, 50 to 480 ppm, 50 to 470 ppm, 50 to 460 ppm, 50

Hydrochloric acid was added to the resulting filtrate, the pH of which was thus adjusted to approximately 9.5. The resulting mixture was diluted with pure water so as to have a potassium ion concentration of approximately 100000 ppm. This resulting mixture was heat-treated at 130° C. for 30 seconds to give a mineral concentrate extract. With the resulting mineral concentrate extract, the potassium ion concentration, sodium ion concentration, calcium ion concentration, magnesium ion concentration, and sulfate ion concentration were analyzed by ion chromatography (IC), the chloride ion concentration was analyzed by ion chromatography, and the TOC was analyzed by combustion oxidation-infrared TOC analysis. In addition, the resulting mineral concentrate extract was stored under refrigeration for two weeks, and then, the degree of turbidity was evaluated by visual observation in accordance with the following five-step rating: “−” (exhibiting high transparency and having no recognizable suspended matter or precipitate); “+” (having a slight amount of recognizable suspended matter and/or precipitate); “++” (having a large amount of recognizable suspended matter and/or aggregate); “+++” (having an even larger amount of recognizable suspended matter and/or aggregate and exhibiting lost transparency); “++++” (having a large amount of suspended matter and deposited aggregate and exhibiting low transparency). Furthermore, the NTU turbidity was measured using a turbidimeter (2100AN TURBISIMETRER, manufactured by Hach Company).
The results of Examples 17 to 20 are tabulated in Table 5. in terms of the components of the mineral extract, a mineral extract having a potassium concentration of 60994 ppm, a chloride ion .concentration of 3030 ppm, and a pH of 11.1 was given in Example 17, a mineral extract having a potassium concentration of 87500 ppm, a chloride ion concentration of 32890 ppm, and a pH of 9.50 was given in Example 18. a mineral extract having a potassium concentration of 100000 ppm, a chloride ion concentration of 13132 ppm, and a pH of 9.51 was given in Example 19, and a mineral extract having a potassium concentration of 111747 ppm, a chloride ion concentration of 8545 ppm, and a pH of 9.48 was given in Example 20. In addition, in terms of turbidity, Example 17 was rated “++++” (having a large amount of suspended matter and deposited aggregate and exhibiting low transparency), and on the other hand, all of Example 18, Example 19, and Example 20, which underwent storage under refrigeration and filtration under cooling, were rated “++” (having a large amount of recognizable suspended matter and/or aggregate). In particular, Example 18, in which a pH adjustment was made before storage under refrigeration and filtration under cooling, was rated “−” (exhibiting high transparency and having no recognizable suspended matter or precipitate). This has proved that the storage under refrigeration and the filtration under cooling are desirable in order to give a mineral extract having high transparency, and a pH adjustment, if made, is desirably made before the storage under refrigeration and the filtration under cooling.
