Description

Mineral dispersant, and mineral dispersion slurry and mineral-reinforced food containing the same {DISPERSING AGENT FOR MINERAL, AND MINERAL-DISPERSED SLURRY AND MINERAL-FORTIFIED FOOD AND DRINK CONTAINING THE SAME}

The present invention relates to a mineral dispersant, and in particular, for the production of mineral-enriched foods (including mineral-enriched foods (including drinks)) by adding minerals such as calcium or magnesium to foods such as milk. The present invention relates to a mineral dispersant for foods that improves dispersion stability of minerals.

In recent years, lack of calcium intake has been a problem as an increase in osteoporosis of elderly people, multiple fractures of young people, etc., and calcium fortified foods have been sold to solve the lack of calcium intake.

For example, calcium fortifying agents added to milk include water-soluble organic acid salts such as calcium lactate and calcium gluconate, and poorly water-soluble calcium salts such as calcium carbonate and calcium phosphate. Application examples are also increasing because it is better to use poorly water-soluble calcium salts such as calcium.

However, since calcium carbonate has a high specific gravity, it has a problem of being precipitated in a liquid for a short time, that is, a problem of suspension stability, and it is difficult to maintain a stable state after adding calcium to foods such as beverages.

As a method for solving the above problem, Japanese Unexamined Patent Application Publication No. 5-319817 proposes a method of adding a hydrophilic emulsifier having a HLB of 10 or more such as sucrose fatty acid ester. In addition, Japanese Unexamined Patent Application Publication No. 7-111879 proposes a method in which a sucrose fatty acid ester is added and ground to a slurry calcium carbonate to obtain a slurry having a specific particle diameter and a geometric standard deviation. However, in such a method of using sucrose fatty acid ester alone as a dispersant, the effect of stabilizing and sustaining the dispersion state of calcium dispersion slurry composed of calcium, water and dispersant for a long time is not sufficient.

Therefore, the present inventor proposes a dispersant for calcium fortified beverages containing a carboxymethylcellulose salt as an active ingredient in Japanese Unexamined Japanese Patent Application No. 2001-27444 for the purpose of maintaining the dispersion state of the calcium dispersion slurry for a long time. have.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a mineral dispersion slurry composed of minerals, water, and a dispersant, and a dispersant capable of sustaining a dispersed state of a food containing the same for a long time.

The present inventors have found further superior long-term dispersion stability by combining thickened polysaccharides with carboxymethylcellulose salts while further studying based on Japanese Patent Application No. 2001-27444. Reached.

That is, the mineral dispersing agent of this invention makes carboxymethylcellulose salt (A) and thick polysaccharide (B) the compounding weight of (A) component X, and the compounding weight of (B) component Y, and 99> {X / (X + Y)} x100> 85, and mix | blended.

In addition, the mineral dispersion slurry of the present invention is made by mixing and dispersing the mineral dispersant, minerals and water.

In addition, the mineral fortified food of the present invention is to contain the mineral dispersant and minerals.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail.

[Mineral fortified foods]

The mineral fortified foods referred to in the present invention are foods in which the minerals are fortified (increased) by adding minerals to foods such as milk, and not limited to beverages, confectionary products such as puddings, jelly and candy, and wheat secondary products such as bread and noodles. Foods other than beverages such as seafood, seafood, and cooked rice are also included.

The food to be fortified may be a food containing original minerals such as calcium, such as milk, processed milk, reduced milk, milk beverage, yogurt, etc. Soft drinks, fruit drinks, and the like). In addition, the case of strengthening by adding other minerals, such as magnesium, to foods, such as milk originally containing calcium, is also included.

As minerals, poorly water-soluble minerals are the object, and water-soluble salts containing calcium, magnesium, etc. are mentioned normally.

Calcium carbonate is typical as a calcium source. In addition to calcium carbonate, for example, calcium phosphate can be used. As calcium carbonate, slurry calcium carbonate is usually used. As a method for obtaining slurry calcium carbonate, for example, a method obtained by passing a carbon dioxide gas through a hydrated lime suspension, washing or purifying egg shells or corals or shells, and then baking or as it is, to form a slurry by wet grinding, may be mentioned. Although it is possible, it is not limited to this.

In addition, as a calcium and magnesium source, magnesium calcium carbonate (dolomite) is mentioned as a suitable example. Moreover, calcium carbonate and magnesium carbonate can also be used together.

[Carboxymethyl cellulose salt (A)]

By using the carboxymethyl cellulose salt of (A) component as a dispersing agent, the viscosity reduction of a calcium dispersion and refinement | miniaturization of an average particle diameter can be aimed at, and the long-term dispersion stabilization effect of a slurry can be improved.

It is preferable to use sodium salt as the carboxymethylcellulose salt. Moreover, it is preferable that 4 weight% aqueous solution viscosity in 25 degreeC is 1-2000 mPa * s. The use of a high-viscosity solution with a 4 wt% aqueous solution viscosity of more than 2000 mPa · s increases the viscosity of the mineral dispersion slurry, worsens the workability when added to foods, and may cause problems such as damage to texture and flavor. There is this. In addition, as a carboxymethylcellulose salt, it is preferable to use the thing whose etherification degree is 0.2-1.5.

Thickened Polysaccharides (B)

Thickened polysaccharides of component (B) include gum arabic, karaya gum, gati gum, gellan gum, tara gum, guar gum, tamarind seed polysaccharides, tragant gum, percelan, pectin, carrageenan, and locust bean gum. These may be individual or may use two or more types together.

By combining such thick polysaccharides with the carboxymethyl cellulose salt, the dispersing effect is higher than that of the carboxymethyl cellulose salt alone, and further excellent long-term dispersion stability can be obtained.

[Compound Ratio]

The compounding ratio (R) of the said (A) component and (B) component is X, the compounding weight of (A) component, and the compounding weight of (B) component is Y, R = {X / (X + Y)} x100. And 99> R> 85.

When the carboxymethyl cellulose salt of component (A) was used alone, the average particle diameter of the mineral dispersion slurry could be fine and low viscosity, but a slight separation occurred due to preservation after the dispersion treatment, resulting in insufficient dispersion stability. In addition, when the dispersion slurry was added to and preserved in the beverage, precipitation occurred at the bottom of the beverage, but the redispersibility of the precipitation was not evaluated. On the other hand, when many thick polysaccharides of component (B) are used together, a mineral dispersion slurry having good dispersibility is obtained, but it is not preferable in terms of odor and taste, the cost is high, and the carboxy methylcellulose salt is used alone. Same as the above, there is a problem that the bottom precipitate generated when added to the beverage and stored is insufficient in redispersibility.

Therefore, in this invention, the compounding ratio (R) of (A) component and (B) component is set in the said predetermined range, and it mix | blends in the said range, and can exhibit synergistic effect by the combination of a carboxymethylcellulose salt and a thick polysaccharide. In addition, it is possible to improve the dispersion stability when insufficient carboxymethyl cellulose salt alone and insufficient carboxymethyl cellulose salt alone or when the thick polysaccharide is used in combination.

[Preparation of Mineral Dispersion Slurry]

The mineral dispersing agent of this invention is obtained by mix | blending and mixing uniformly the said (A) component and (B) component, and is normally used in the form of aqueous solution. What is necessary is just to add the said aqueous solution which melt | dissolved what mixed (A) component and (B) component in water, and to prepare, and also to prepare, after mixing aqueous solution of (A) component and (B) component separately, and also to (B) After preparing the aqueous solution of the component, the component (A) may be added and mixed as it is.

It is preferable that the mineral dispersing agent of this invention is 1-2000 mPa * s in 4 weight% aqueous solution viscosity in 25 degreeC. The use of a high viscosity of 4 wt% aqueous solution viscosity of more than 2000 mPa · s increases the viscosity of the mineral dispersion slurry, worsens the workability when added to foods, and may also cause problems such as damage to texture and flavor. have.

The mineral dispersion slurry of this invention is obtained by mixing and disperse | distributing the said mineral dispersing agent, a poorly water-soluble mineral, and water. Dispersion treatment is preferably carried out so that the aggregated poorly water-soluble mineral particles are in the state of primary particles by grinding, and more specifically, a slurry having an average particle diameter of the mineral particles of 1.0 µm or less is prepared. Such dispersion treatment can be carried out using a known mill such as a homogenizer, roll mill, ball mill, coball mill, bead mill, or the like.

In detail, for example, in the case of using calcium carbonate as a poorly water-soluble mineral, the dispersant aqueous solution obtained as described above is added to slurry calcium carbonate, and both are mixed by a mixing stirring vessel, a line mixer, or the like, and then homogenizer Calcium carbonate dispersion slurry can be obtained by disperse | distributing in a dispersing apparatus, such as these.

It is preferable that the quantity of the dispersing agent with respect to the mineral to disperse is 6.5 weight% or less, More preferably, it is 1-5 weight%. If it is added more than 6.5% by weight, the viscosity of the slurry itself is increased, so that the stability is worsened, and when added to a beverage or the like, it may affect the texture and flavor. If it is less than 1% by weight, it is insufficient to stably disperse the minerals.

It is preferable that the ratio (weight%) of each component in a mineral dispersion slurry is water-soluble mineral: dispersant: water = 1-50%: 0.01-1.25%: 46.75-98.99% (100% in total), and 8- As for 20%: 0.08-1%: 79-91.92%, it is more preferable.

The mineral dispersion slurry obtained as described above may be dried powder to prepare a mineral-containing powder. Dry powdering of the mineral dispersion slurry not only avoids the spoilage of the slurry during long-term storage, but also reduces the distribution costs such as filling container costs, refrigeration equipment costs, refrigeration equipment, transportation costs, etc., when transporting them to the respective destinations.

There is no restriction | limiting in particular about the dryer used for drying a mineral dispersion slurry, A well-known method can be used, For example, the method of liquid spray type dryers, such as a spray dryer and a slurry dryer, and lyophilization etc. can be used. In powdering, monosaccharides such as fructose and glucose, disaccharides such as sucrose and lactose, polysaccharides such as dextrin, and sugar compounds such as sugar alcohols such as sorbet may be used as the film forming agent.

The mineral dispersion slurry and the mineral containing powder prepared as mentioned above can be made into a mineral fortified food by adding and disperse | distributing to foods, such as a drink. This mineral dispersion slurry has very good dispersibility in water, and the mineral-containing powder also has very good redispersibility in water. Therefore, both of them can be easily dispersed in a beverage or water using a stirring mixture tank which is usually used without using a special disperser or agitator.

The mineral-enriched beverage thus obtained may be removed using a purifier or the like, or sterilized at a high temperature and high pressure.

Slurry addition amount, for example, when preparing a calcium fortified beverage, it is preferable to select so that the amount of calcium increase per 100g of beverage is 100 ~ 500mg. The content of the dispersant in the calcium fortified beverage is usually 0.00002 to 2% by weight, preferably 0.00005 to 1% by weight. If it is less than 0.00002% by weight, there is a possibility that a problem of deterioration in dispersion stability may occur, and if it is more than 2% by weight, there may be a problem that a odor peculiar to a dispersant is felt and that an economic disadvantage is caused.

In order to suppress the dispersion slurry viscosity, ionic emulsifiers such as succinic acid monoglyceride, citric acid monoglyceride and lecithin may be used in combination, or emulsifiers such as monoglyceride and sorbitan fatty acid ester may be used in combination.
