Description

Additive composition containing inorganic particles, method for preparing the same, and food composition containing the same

Technical Field

The present invention relates to an additive composition containing inorganic particles, a method for preparing the same, and a food composition containing the same, and more particularly, to an additive composition containing inorganic particles, which can be added to foods such as yogurt, cow milk, fruit juice, milk-containing coffee (コ - ヒ - フレツシユ), powdered milk, and snack, can effectively enrich minerals, and has excellent dispersion stability and good flavor, a method for preparing the same, and a food composition containing the same.

Background

In recent years, there has been a problem of insufficient intake of calcium, magnesium, iron, and the like, and this tendency is particularly remarkable in children and the elderly who are well developed.

It goes without saying that calcium is important for bone formation and plays an important role in muscle contraction and maintaining homeostasis in the body. Magnesium has the functions of relaxing, expanding muscles and blood vessels, and the like, and is an essential mineral for human beings. When magnesium is deficient, hypertension, angina pectoris, hyperlipidemia, etc. are easily caused. Magnesium has a great relationship with calcium metabolism, and when magnesium is insufficient, various symptoms accompanied by abnormal calcium metabolism appear. Magnesium is also involved in many enzymatic reactions and is thought to maintain homeostasis in the organism.

However, in recent years, magnesium has been greatly reduced in the food finishing stage due to the eurization of the dietary pattern and the intake of grains with high whiteness, so that the dietary pattern of modern people is likely to be deficient in magnesium, and products reinforced with magnesium are receiving attention. In recent years, women who develop anemia due to iron deficiency are often seen. This tendency is particularly pronounced in women of high school and young adults. The most significant cause of such iron deficiency anemia is the problem of dietary pattern, but women are under the circumstances that iron deficiency easily causes anemia because of the increase in iron demand due to physiological bleeding and pregnancy, and insufficient intake due to weight loss, and the like, and it is generally considered that about half of women are iron deficiency. In order to solve such iron deficiency, iron-enriched foods have been sold, and many commercial products enriched with iron in milk, soft drinks, and the like have been sold.

In order to solve the above-mentioned problem of insufficient intake of various minerals, mineral-fortified foods have been sold, and attempts have been made to provide mineral-fortified cows 'milk to which minerals are further added even to cows' milk which is generally considered to have a high mineral content.

For example, in milk and yogurt, water-soluble minerals in the form of inorganic or organic acids such as calcium lactate, calcium chloride, magnesium chloride, and ferric ammonium citrate are added for the purpose of enriching the minerals; water insoluble inorganic forms of minerals such as calcium carbonate, calcium phosphate, dolomite, ferric pyrophosphate, etc. However, water-soluble minerals in the form of inorganic or organic acids tend to inhibit the stability of proteins in milk and yogurt, and it is difficult to mix them at a certain amount or more, so that there is a disadvantage that the mineral materials cannot be used in large amounts. And minerals have a unique bitter taste and thus also have problems in flavor.

On the other hand, although the water-insoluble inorganic mineral is not water-insoluble and therefore does not inhibit the stability of protein in cow's milk or yogurt, and can be used in a large amount in terms of the amount to be added, the inorganic mineral has a high specific gravity of 2.1 or more as a whole and precipitates in a short time when dispersed in cow's milk, and therefore, is not preferable in terms of food appearance, and as a result, the amount to be added is limited, and there is a disadvantage that the mineral cannot be used in a large amount.

Many methods have been proposed to compensate for the above-mentioned disadvantages and to add a large amount of calcium for food use, and for example, in Japanese patent application laid-open No. 9-9911, a method of improving dispersibility by adding at least one selected from the group consisting of phospholipids and protein decomposition products to calcium carbonate and wet-pulverizing the mixture has been proposed. However, in the method of adding phospholipids and protein decomposition products as described above, there are problems in flavor because of the peculiar odor and bitterness of phospholipids, and further, according to the above publication, since the average particle size of the calcium dispersion is 1 to 3 μm, the milk to which calcium carbonate obtained by this method is added is poor in recovery rate of calcium carbonate in a centrifugal classifier such as a clarifier in the production process of the milk, and is liable to settle in foods such as milk, and it is difficult to say that the milk is suitable for addition to foods which can be preserved for a long period of time such as milk.

Japanese patent application laid-open No. Sho 55-84327 proposes: mixing (1) a cation supply source selected from the group consisting of calcium, magnesium, iron, copper, boron, zinc, manganese, molybdenum, arsenic, silver, aluminum, barium, bismuth, mercury, nickel, lead, platinum, antimony, and tin, (2) an alkali phosphate supply source selected from the group consisting of potassium phosphate, dipotassium hydrogen phosphate, a mixture of an alkali hydroxide metal and phosphoric acid, and an alkali hydrogen phosphate metal, and (3) an organic acid having at least 3 carboxyl groups in this order of cation supply source and alkali phosphate supply source, and finally adding an organic acid source to obtain a mineral-fortified substance.

However, according to the above-mentioned publication, the effective utilization rates of various minerals are not necessarily sufficient in the dispersed state of the food additive composition produced by this method, and similarly to Japanese patent application laid-open No. Hei 9-9911, in the production process of cow milk to which the food additive composition obtained by this method is added, recovery rates of various minerals in a centrifugal classifier such as a clarifier are poor, and the cow milk is liable to settle in foods such as cow milk, and it is difficult to say that the cow milk has physical properties that can be added to foods that can be stored for a long time. There is a possibility that the content of an alkali metal salt of an organic acid having a carboxyl group or the like contained in the composition is too large, and when the food additive composition obtained by this method is added to a food, the flavor is significantly reduced due to bitterness, astringency or the like, and the value of the food is greatly impaired, and this method is not a very preferable method in terms of flavor.

Recently, with the progress of containers and storage methods for storing liquid foods such as cow milk, yogurt, and fruit juices for a long period of time, there is an increasing tendency that the foods are stored for a long period of time in shops, vending machines, and large refrigerators at home, and if calcium carbonate particles added to the same kind of foods for the purpose of calcium fortification are not well dispersed in the foods, the liquid foods are deposited on the bottom of the food containers during long-term storage, and when cow milk and fruit juice liquid foods are drunk, many of the deposits give unpleasant and unclean feelings to the drinkers.

Therefore, liquid foods which are currently sold with the aim of calcium fortification to which inorganic particles such as calcium carbonate prepared according to the conventional technique are added have such inconveniences that the inorganic particles need to be added in an extremely small amount because the dispersion stability period of the inorganic particles in the food is short, and that it needs to be limited to the range of liquid foods which are generally consumed by consumers between 1 and 2 days after purchase.

In view of the above circumstances, the present invention has been made to solve the above problems, and provides an inorganic particle-containing additive composition having excellent dispersibility and flavor as an additive for foods such as yogurt, cow milk, fruit juice, milk-containing coffee, milk powder, and snack, a method for producing the same, and a food composition obtained by adding the additive composition.

Best Mode for Carrying Out The Invention

The present invention is described in detail below. In the following description, when it is not necessary to particularly distinguish between the additive slurry composition containing inorganic particles and the additive powder composition containing inorganic particles, both are referred to as inorganic particle-containing additive compositions.

The polyvalent metal compound used in the present invention includes calcium hydroxide, magnesium hydroxide, iron hydroxide, calcium oxide, magnesium oxide, iron oxide, calcium chloride, magnesium chloride, iron chloride, calcium carbonate, magnesium carbonate, iron carbonate, calcium nitrate, magnesium nitrate, iron nitrate, calcium sulfate, magnesium sulfate, iron sulfate, calcium phosphate, magnesium phosphate, iron phosphate, ferric pyrophosphate, dolomite, and the like, and it is preferable to use at least one selected from the group consisting of calcium hydroxide, magnesium hydroxide, iron hydroxide, calcium oxide, magnesium oxide, iron oxide, magnesium carbonate, calcium carbonate, iron carbonate, and dolomite, either singly or in combination of 2 or more as necessary, in order to obtain an inorganic particle-containing additive composition having a better dispersibility.

The organic acid having a carboxyl group used in the present invention includes malic acid, succinic acid, citric acid, adipic acid, fumaric acid, glutamic acid, and alkali metal salts and polyvalent metal salts thereof, and 2 or more thereof may be used alone or in combination as necessary, and in order to obtain an additive composition containing inorganic particles having a better dispersibility, at least one of citric acid, potassium citrate, sodium citrate, calcium citrate, magnesium citrate, ferric ammonium citrate, ferric citrate, and ferric sodium citrate is preferably used.

The phosphoric acid source used in the present invention includes phosphoric acid, condensed phosphoric acid and the like, and 2 or more of these may be used alone or in combination as necessary. The condensed phosphoric acid includes pyrophosphoric acid, tripolyphosphoric acid, tetrapolyphosphoric acid, pentapolyphosphoric acid, hexametaphosphoric acid, etc., and they may be used singly or in combination of 2 or more kinds.

The phosphoric acid source/alkali metal source used in the present invention includes an alkali metal of phosphoric acid and/or an alkali metal of condensed phosphoric acid, or phosphoric acid and/or condensed phosphoric acid, and an alkali metal, and more specifically, a sodium salt and a potassium salt of phosphoric acid, a sodium salt and a potassium salt of condensed phosphoric acid, a mixture of phosphoric acid and a sodium salt and a potassium salt, and a mixture of condensed phosphoric acid and a sodium salt and a potassium salt, and 2 or more kinds thereof may be used alone or in combination as necessary.

The alkali metal source used in the present invention is sodium hydroxide, potassium hydroxide, sodium oxide, potassium oxide, sodium carbonate, sodium hydrogencarbonate, potassium carbonate and potassium hydrogencarbonate, and these may be used alone or in combination of 2 or more as required.

The inorganic particle-containing additive composition of the present invention may be obtained in the form of a slurry composition, or may be obtained in the form of a powder composition by drying it to obtain a powder.

First, the additive slurry composition containing inorganic particles of the present invention is prepared by adding water and a polyvalent metal compound, an organic acid having a carboxyl group, a phosphoric acid source, and an alkali metal source to prepare a slurry. The mixing method can be roughly classified into the following methods (I), (II), (III) and (IV), and any method may be used, or 2 or more methods may be used in combination.

In the above method, the method (III) or (IV) is preferably used to obtain a slurry having a better dispersibility.

In order to obtain the inorganic particle-containing additive slurry composition of the present invention, it is preferable that the molar ratio of each component in the preparation is within a specific range. That is, the polyvalent metal ion and the organic acid ion having a carboxyl group are in the range of 0.8: 1 to 20: 1, and in order to obtain an additive composition containing inorganic particles having a better dispersibility, the ratio is more preferably in the range of 1.8: 1 to 7: 1, and still more preferably in the range of 1.8: 1 to 3.5: 1.

The ratio of the organic acid ion having a carboxyl group to the phosphate ion is preferably 1: 0.6 to 1: 13.2, and in order to obtain an additive composition containing inorganic particles having a better dispersibility, the ratio is more preferably 1: 1 to 1: 5, and still more preferably 1: 1.3 to 1: 2.4. The ratio of the organic acid ion having a carboxyl group to the alkali metal ion is 1: 0.5 to 1: 8, and in order to obtain an additive composition containing inorganic particles having a better dispersibility, the ratio is more preferably 1: 1.5 to 1: 5, and still more preferably 1: 2 to 1: 4.

When the molar ratio of the polyvalent metal ion to the organic acid is less than 0.8, the dispersion state is liable to be unstable, which is not preferable; when the molar ratio exceeds 20, metal ions tend to remain in an ionic state, and therefore, when used in, for example, cow milk, the stability of protein tends to be impaired, and the protein tends to be thickened, and in extreme cases, gelation tends to cause deterioration in flavor, which is not preferable.

When the molar ratio of the phosphate ion to the organic acid is less than 0.6, the dispersion state tends to be unstable, which is not preferable; when the molar ratio exceeds 13.2, inorganic polyvalent metal aggregates tend to be easily formed, and in such a case, for example, when used in cow milk or the like, the inorganic polyvalent metal aggregates are undesirably precipitated in a large amount at the bottom of the vessel.

When the molar ratio of the alkali metal ion to the organic acid is less than 0.5, the dispersion state tends to be unstable, which is not preferable; when the molar ratio exceeds 8, the basicity tends to be too strong, and when a strong basic substance is added to various foods, the flavor tends to be impaired, which is not preferable.

The order of mixing water, the polyvalent metal compound and the organic acid having a carboxyl group is not particularly limited in the production of the precursor of the present invention. The method (III) can be further divided into the following methods (a), (b), (c) and (d) by adding a phosphoric acid source and an alkali metal source, and any of these methods can be used, or 2 or more methods can be used in combination.

(a) Adding an alkali metal phosphate and/or an alkali metal of condensed phosphoric acid;

(b) simultaneously adding alkali metal phosphate and/or alkali metal and alkali metal salt of condensed phosphoric acid;

(c) simultaneously adding phosphoric acid and/or condensed phosphoric acid and alkali metal salt;

(d) an alkali metal phosphate and/or an alkali metal of condensed phosphoric acid is added, and then an alkali metal salt is added.

The temperature at which the components are mixed to prepare the inorganic particle-containing additive slurry composition of the present invention is not particularly limited, but is preferably in the range of 1 to 70 ℃ and more preferably in the range of 10 to 40 ℃ from the viewpoint of obtaining an inorganic particle-containing additive composition having a better dispersibility. It is more preferable to mix all the components and heat the mixture to a temperature in the range of 80 to 230 ℃ because the stability over a long period of time is more easily exhibited.

When the liquid temperature during mixing exceeds 70 ℃, coarse particles tend to be formed in the liquid, and it is difficult to maintain stable dispersion characteristics for a long time, which is not preferable, and when the liquid temperature is less than 1 ℃, water as a solvent tends to freeze easily, and it tends to be difficult to obtain a composition having good dispersibility.

The additive composition containing inorganic particles of the present invention can be prepared by the following operations: namely, a slurry prepared by the method selected from the above (I) to (IV) and containing a polyvalent metal mainly composed of at least one compound selected from phosphoric acid compounds, a phosphoric acid ion, an organic acid having a carboxyl group and an alkali metal is washed. However, indispensable conditions for preparing the inorganic particle-containing additive composition of the present invention are: the amount X (mg/kg) of the alkali metal contained in the solid content of the inorganic particle-containing additive slurry and the electrical conductivity Y (mS/cm) when the inorganic particle-containing additive slurry is adjusted to a solid content concentration of 10% by weight satisfy the following conditions (a) and (b), preferably the following conditions (c) and (d), and more preferably the following conditions (e) and (f).

(a)70≤X≤90000

(b)0.1≤Y≤15

(c)70≤X≤39000

(d)0.1≤Y≤7

(e)150≤X≤10000

(f)0.25≤Y≤1.8

When the amount X (mg/kg) of the alkali metal contained in the solid component of the inorganic particle-containing additive slurry composition is less than 70, the dispersibility of the inorganic particle-containing additive composition tends to be lowered, and it is difficult not only to obtain a stable product but also to make a high concentration uneconomical; when X exceeds 90000, the metallic taste becomes strong when added to food. When the additive slurry composition containing inorganic particles is adjusted to have a conductivity Y (mS/cm) of less than 0.1 at a solid content concentration of 10% by weight, the additive composition containing inorganic particles is liable to reagglomerate, and when added to a beverage, it is difficult to obtain a stable product, and when Y exceeds 15, the flavor is reduced by bitterness, astringency, or the like when added to a food, and the taste of the food is greatly impaired.

The amount X (mg/kg) of the alkali metal contained in the solid component of the additive slurry composition containing inorganic particles in the present invention can be calculated by measurement as follows.

Measurement machine: shimadzu atomic absorption spectrophotometer AA-6700F

Preparation of a sample: the additive slurry composition containing inorganic particles was powdered, about 2g was dissolved in 3g of nitric acid, and then prepared to 100ml with distilled water to prepare a measurement sample. Further, the alkali metal may be further diluted as necessary depending on the amount of the alkali metal contained.

Solvent: distilled water

The conductivity Y (mS/cm) at the time of adjusting the inorganic particle-containing additive slurry composition of the present invention to a solid content concentration of 10% by weight can be calculated by measurement as follows.

Measurement machine: model SC82 electrical conductivity meter made by Chuanchuan

Preparation of a sample: the concentration of the solid content of the additive slurry containing inorganic particles was adjusted to 10% by weight, and this was used as a measurement sample.

Solvent: distilled water

The method for washing the additive slurry composition containing inorganic particles of the present invention is not particularly limited, and a centrifuge such as a decanter or a clarifier, a cloth type washing machine such as a spin filter, and the like can be used.

The timing for washing the inorganic particle-containing additive slurry composition of the present invention is not particularly limited, and the latter method is preferred in order to prepare an inorganic particle-containing additive slurry composition having a higher dispersibility, since the inorganic particle-containing additive slurry composition can be washed with water when the polyvalent metal, the phosphate ion, the organic acid having a carboxyl group and the alkali metal are mixed, or the polyvalent metal, the phosphate ion, the organic acid having a carboxyl group and the alkali metal are mixed, heated and washed.

The inorganic particle-containing additive slurry containing a polyvalent metal, a phosphate ion, an organic acid having a carboxyl group, and an alkali metal [ hereinafter referred to as an inorganic particle-containing additive slurry (. alpha.) ] having the conditions of the above (a) and (b) is extremely excellent in redispersibility in a liquid and long-term storage stability in a liquid, and is excellent in flavor, but in order to obtain dispersion stability in foods in an acidic region such as yogurt and dispersion stability for a longer period of time such as long-term storage of cow milk, it is preferable to produce an additive slurry containing inorganic particles [ hereinafter referred to as an inorganic particle-containing additive slurry (. beta.) ], wherein the emulsion stabilizer is contained in an amount of 2 to 80 parts by weight relative to 100 parts by weight of the solid portion of the additive slurry composition (. alpha.) containing inorganic particles.

When the content of the emulsion stabilizer is less than 2 parts by weight based on 100 parts by weight of the solid portion of the inorganic particle-containing additive slurry (α) of the present invention, it is not preferable because it is difficult to maintain emulsion stability for a long period of time and to exert a dispersion stabilizing effect on acidic foods when the inorganic particle-containing additive slurry (β) is added to foods such as canned fruit juice and yogurt in the form of beverage; on the other hand, when the amount of the compound is more than 80 parts by weight, the viscosity of the product is increased, which is not preferable in terms of texture, and the product is difficult to produce at a high concentration in terms of handling due to the increase in viscosity of the product, and is not preferable from the viewpoint of economy because the product can be produced only with a reduced concentration of the solid portion.

Examples of the emulsion stabilizer used in the present invention include gellan gum, carrageenan, sodium alginate, guar gum, karaya gum, carboxymethyl cellulose (hereinafter referred to as CMC), propylene glycol alginate (hereinafter referred to as PGA), gum arabic, tamarind gum, ghatti gum), tragacanth gum, xanthan gum, pullulan, cassia gum, locust bean gum, arabinogalactan, スクレロガム (sclerogum), condensed phosphate, sucrose stearate, sucrose palmitate, sucrose myristate, sucrose oleate, sucrose laurate and other sucrose fatty acid esters having an HLB of 8 or more, triglycerol, pentaglycerol, hexaglycerol, decaglycerol and other polyglycerol fatty acid esters having 6 to 22, preferably 14 to 18, carbon atoms of fatty acids, lecithin, modified starch, and soybean polysaccharides, and 2 or more thereof may be used alone or in combination as necessary, in order to obtain longer dispersion stability, at least one selected from sucrose fatty acid esters having HLB of 8 or more, PGA, CMC, gum arabic, arabinogalactan, condensed phosphate, polyglycerin fatty acid esters, lecithin, and modified starch is preferably used.

Further, the amount X (mg/kg) of the alkali metal contained in the solid content of the inorganic particle-containing additive slurry composition (β) of the present invention and the electrical conductivity Y (mS/cm) when the inorganic particle-containing additive slurry composition (β) is adjusted to a solid content concentration of 10% by weight preferably satisfy the conditions (a) and (b) described above, more preferably satisfy the conditions (c) and (d) described above, and still more preferably satisfy the conditions (e) and (f).

In the case of products requiring particularly long-term dispersion stability such as canned fruit juice, it is more preferable to add 2 to 80 parts by weight of an emulsion stabilizer to 100 parts by weight of the solid content of the additive slurry composition (α) containing inorganic particles, and then disperse the emulsion stabilizer by a pulverizer and/or a disperser.

The pulverizer and disperser used in the present invention are not particularly limited, and a wet pulverizer such as a ball mill, sand mill, コボ - ルミル (Kovor mill); an ultrasonic disperser, an ultrafine atomizer, an ultrafine nanoparticle processor (Nanomizer), a Microfluidizer (Microfluidizer), アルテイマイザ - (Ultimizer), an emulsifier, and a disperser.

The additive powder compositions (. alpha.) and (. beta.) containing inorganic particles can be prepared by powder-drying the additive slurry compositions (. alpha.) and (. beta.) containing inorganic particles prepared as described above. When the additive slurry composition (α) or (β) containing inorganic particles is dried, the cake-like solid matter obtained by washing may be dried as it is, or the cake-like solid matter obtained by diluting the slurry in water and slurrying the slurry again may be dried, and the latter method is preferable from the viewpoint of obtaining a dried powder having a better redispersibility. The dryer used for drying the additive slurry compositions (α) and (β) containing inorganic particles is not particularly limited, but from the viewpoint of preventing the deterioration of various surface-treating agents, it is preferable to carry out drying in an extremely short time, and from this viewpoint, a droplet spray dryer such as a spray dryer, a slurry dryer using a ceramic medium in a heated fluidized state, or a reduced pressure dryer is preferably used as the dryer.

Regarding the conditions of X and Y, the case of the inorganic particle-containing additive powder composition (. alpha.) or (. beta.) is the same as that of the above-mentioned inorganic particle-containing additive slurry composition (. alpha.) or (. beta.), that is, X is the amount of alkali metal (mg/kg) contained in the inorganic particle-containing additive composition powder, and Y is the electric conductivity Y (mS/cm) at which the inorganic particle-containing additive composition powder is adjusted to a solid content concentration of 10% by weight using water as a solvent.

The weight-average particle diameter K (μm) in the particle size distribution of the inorganic particle-containing additive composition (α) or (β) of the present invention preferably satisfies the following condition (χ), and in food applications requiring long-term storage dispersion stability, the condition (ψ) is preferably satisfied, and the condition (ω) is more preferably satisfied.

(χ)0.02≤K≤0.8

(ψ)0.02≤K≤0.3

(χ)0.02≤K≤0.1

When the weight-average particle diameter of the additive compositions (α) and (β) containing inorganic particles is larger than 0.8 μm in the particle size distribution, the additive compositions tend to settle and cannot be used for food applications which can be stored for a long period of time. On the other hand, if the average particle size is too small, the solubility of various minerals tends to increase, and for example, if the average particle size is too small, proteins and the like in cow milk tend to easily aggregate, and therefore, it is preferably 0.02 μm or more.

The weight-average particle diameter in the particle size distribution of each mineral in the additive composition (α) or (β) containing inorganic particles of the present invention is calculated by measurement under the following conditions.

Measurement machine: shimadzu corporation SA-CP4L

Preparation of a sample: the additive compositions (. alpha.,. beta.) containing inorganic particles were dropped into a solvent at 20 ℃ as described below to prepare a particle size distribution measuring sample.

Solvent: distilled water

Pre-dispersing: ultrasonic dispersion was carried out for 60 seconds using an Ultrasonic Homogenizer

Measuring temperature: 20.0 ℃ plus or minus 2.5 DEG C

When water-soluble calcium in the form of an inorganic or organic acid is added to food such as cow milk, soluble calcium ions tend to interfere with the stability of protein in cow milk, and there is a disadvantage that a certain amount or more cannot be mixed, whereas the additive composition (α) or (β) containing inorganic particles of the present invention is a composition having both an organic acid form and an inorganic acid form, and the concentration of calcium ions in the additive composition (α) or (β) containing inorganic particles is extremely low, so that the above-mentioned problem occurring when soluble calcium in the form of an inorganic or organic acid is added does not occur even when it is added to food such as cow milk.

The calcium ion concentration in the present invention is measured and calculated under the following conditions.

Measurement machine: ION METER IM-40S manufactured by east Asia electric wave industry

Preparation of a sample: the additive compositions (. alpha.,. beta.) containing inorganic particles were prepared in an amount of 10% by weight, and centrifuged at 10,000rpm for 1 hour to obtain a supernatant as a measurement sample.

Solvent: distilled water

The inorganic particle-containing additive composition (α) or (β) of the present invention is excellent in redispersibility in water, and can be easily dispersed in water without using a special disperser, stirrer or the like.

Therefore, when the inorganic particle-containing additive composition (α) or (β) of the present invention is used for producing food such as mineral-fortified milk, it is sufficient to disperse the inorganic particle-containing additive composition (α) or (β) in milk by directly adding the inorganic particle-containing additive composition (α) or (β) of the present invention to milk and vigorously stirring the mixture, and if an aqueous dispersion of minerals obtained by previously dispersing the inorganic particle-containing additive composition (α) or (β) in water is added to milk, there is no effect. In addition, the reduced milk may be prepared by adding the additive composition (α) or (β) containing inorganic particles of the present invention to cream or cream-making oil dissolved at a temperature of about 60 ℃, dispersing the mixture by high-speed stirring, adding reduced skim milk or skim milk thereto, and homogenizing the mixture.

The mineral-fortified milk and the like produced by these methods have a greatly reduced amount of minerals removed by the clarifier as compared with the case of adding minerals produced by conventional methods. That is, the minerals can be kept extremely stable in cow's milk, yogurt, and fruit juices to which the additive composition (α) or (β) containing inorganic particles of the present invention is added. Since the inorganic particle-containing additive composition (α) or (β) of the present invention has good mineral dispersibility, it can be added to milk or the like with a short stirring time, and therefore, mineral aggregation which is visible when stirred for a long time in cream does not occur. In addition, the additive composition (α) or (β) containing inorganic particles of the present invention does not cause a unique flavor or odor due to a water-soluble calcium agent and gelation of a product even when added in a large amount to cow milk, milk-containing coffee, or the like, and does not affect the flavor or texture of the product.

The inorganic particle-containing additive composition (α) or (β) of the present invention may be used for the purpose of mineral fortification in liquid foods such as cream, soup, coffee, black tea, oolong tea, soybean milk, sports drinks, and near-water drinks (for the purpose of mineral fortification; alcoholic beverages such as wine and liquor; cheese, chewing gum, bread, snack, flour, and other food products or tablets.

The amount of the inorganic particle-containing composition (. alpha.,. beta.) of the present invention is not particularly limited, but 1 to 1000mg of calcium, 0.5 to 500mg of magnesium, and 0.1 to 20mg of iron are preferably added to various foods, more preferably 5 to 500mg of calcium, 2.5 to 250mg of magnesium, and 0.1 to 10mg of iron are added, and still more preferably 10 to 300mg of calcium, 5 to 150mg of magnesium, and 0.1 to 5mg of iron are added.

The additive composition (alpha) or (beta) containing inorganic particles of the present invention is used in combination with mineral salts in water-soluble inorganic form such as calcium lactate, calcium chloride, magnesium sulfate, magnesium chloride, sodium ferric citrate, ammonium ferric citrate, etc., without any problem.

The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited to these examples.

Example 1

The parent material was prepared by mixing 1142.9g of water and 155.4g of calcium hydroxide, 192g of citric acid (anhydrous) and 343g of 40% phosphoric acid with stirring.
