Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a process for producing a water-insoluble neutralized salt-forming mineral composition having good dispersibility, particularly good dispersibility in an aqueous phase.

[0002]

2. Description of the Related Art In general, water-insoluble minerals have a high specific gravity (usually 1.5 or more), so that they easily precipitate in water.
When stable dispersion in water is desired, first, micronization is required. JP-A-57-110167 and JP-A-08-7938.
In the physical crushing method using a ball mill, a jet mill, or the like, which is mentioned in 1 or the like, fine particles of the order of several microns are the limit, and sufficient dispersion stability cannot be obtained. As a method to obtain finer submicron order fine particles,
Many chemical production methods utilizing a neutralization salt formation reaction have also been reported, and it is possible to produce ultrafine particles in units of 1/100 micron. There is a problem of coarse particles.

[0003] As a method of suppressing this, a method of adsorbing and holding primary fine particles in a polymer network structure thereof by adding a thickening polysaccharide such as crystalline cellulose, pectin, carrageenan, guar gum or the like (Japanese Patent Application Laid-Open No. 56-1981). 117753, JP-B-57-35945, JP-A-09-191855),
Alternatively, a method has been proposed in which insoluble minerals are mixed and dispersed in fats and oils, and the specific gravity is reduced by adjusting the blending amount of the fats and oils to 30% by weight or more (Japanese Patent Laid-Open No. 57-110167). There is a problem that it is necessary to add a large amount of substances other than insoluble minerals, and that the dispersing effect becomes extremely low and the dispersing effect is significantly reduced. As a measure to solve this problem, a method of treating the surface of fine particles of insoluble minerals with an organic acid or an alkali agent (JP-A-61-15645)
) And a method using a surfactant such as sucrose ester (JP-A-63-173556), and JP-A-5-319.
No. 817), etc., but in the former, metal ions constituting the insoluble mineral are easily released into the aqueous phase,
In the latter case, when subjected to heat treatment such as sterilization, problems such as separation of the surfactant layer adsorbed on the surface of the fine particles and promotion of secondary aggregation occur.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a water-insoluble neutralized salt-forming mineral composition without adding a large amount of substances such as crystalline cellulose and fats and oils, and has a high heat stability by a minimum necessary treatment. An object of the present invention is to provide a method for producing a neutralized salt-forming mineral composition having good dispersibility. Hereinafter, the present invention will be described in detail.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above problems, and as a result, in the production of a water-insoluble neutralized salt-forming mineral composition, first, enzymatically degraded lecithin was used. Later, they found that a water-insoluble neutralized salt-forming mineral composition having good dispersibility without cohesion could be obtained by using a polyglycerin fatty acid ester and a thickening polysaccharide, and completed the present invention. A feature of the present invention is that a primary adsorption layer of enzyme-decomposed lecithin is formed on the surface of neutralized salt-forming fine particles of a metal salt having an average particle diameter of 2 μm or less and a solubility product in water at 25 ° C. of 1.0 × 10 −7 or less. Then, a secondary adsorption layer of polyglycerin fatty acid ester is formed to form coating-treated neutralized salt-forming fine particles having excellent thermal stability, and these fine particles are supported on the three-dimensional structure of the thickening polysaccharide. An object of the present invention is to produce a neutralized salt-forming mineral composition having no cohesiveness and excellent dispersibility.

Here, the solubility product is the product of the molar concentrations (mol / liter) of cations and anions in a saturated solution of salts, and has a correlation with the general solubility as follows.
That is, assuming that the metal salts are Ma and Xb and the solubility is S, the solubility product (Ksp) is represented by the following equation. Ksp = [M] a [X] b = (aS) a × (bS) b
= Aa × bb × S (a + b) [] is the ion concentration (mol / liter) Taking calcium carbonate (CaCO ₃ ) as an example,
₃ is 4.7 × 10 −9, and when applied to the equation, [Ca] 1 [CO ₃ ] 1 = S 2 = 4.7 × 10 −9, and the solubility S of CaCO ₃ is about 6. It was 9 × 10 −5 mol / l (6.9 ppm), which was judged to be water-insoluble.

[0008] From this, the solubility product is 1.0 × 10-
The solubility of salts larger than 7 is about 3.2 × 10 −3 mol / l, which is nearly 100 times that of CaCO ₃ , and is not strictly water-insoluble. Due to the pH change, the surface of the insoluble salt is likely to be unstable, which causes the formation of the adsorption interface layer of the enzyme-decomposed lecithin to be hindered. Further, in order to stably disperse a high specific gravity water-insoluble mineral based on Stokes' theorem, it is necessary that the average particle diameter is fine particles of submicron order of 2 microns or less, which is extremely special and expensive. A neutral salt forming method, which is inexpensive and easy to adjust the particle diameter, is preferable to a physical crushing method requiring a simple apparatus. As a neutral salt forming method, ferric chloride (FeCl ₃ ) and tetrasodium pyrophosphate (Na ₄ (P ₂ P), such as ferric pyrophosphate (Fe ₄ (P ₂ O ₇ ) ₃ ), are used.
O ₇ ), which uses a strong acid-strong basic salt neutralization reaction, or phosphoric acid (H ₃ PO ₄ ) and calcium hydroxide (Ca (O (O)) such as tribasic calcium phosphate (Ca ₃ (PO ₄ ) ₂ ).
H) ₂ ) which uses a neutralization reaction with a weak acid-strongly basic salt, etc., is known.
Although 0.1 micron ultrafine particles were generated, secondary aggregation immediately occurred and was collected as an aggregate of approximately 0.2 to 2 microns. According to the present invention, the form of the primary particles is maintained by effectively suppressing the secondary aggregation, and stable dispersibility is obtained.

The enzymatically degraded lecithin used in the present invention comprises:
Mono-acylglycerophospholipids centered on lysophosphatidylcholine, lysophosphatidylethanolamine, lysophosphatidylinositol and lysophosphatidylserine obtained by selectively hydrolyzing the fatty acid ester portion of plant lecithin or egg yolk lecithin with phospholipase A, and One or more selected from the group consisting of phosphatidic acid, lysophosphatidic acid, phosphatidyl glycerol, and lysophosphatidyl glycerol produced using phospholipase D. Preferred are lysophosphatidylcholine, lysophosphatidylethanolamine, and lysophosphatidylserine, and more preferred is lysophosphatidylcholine. The phospholipase used in the enzymatic degradation may be any one having phospholipase A and / or D activity, regardless of its origin, such as animal origin such as pig pancreas, plant origin such as cabbage, or microorganism origin such as molds.

[0010] All of the above-mentioned enzymatically degraded lecithins have a surfactant activity, and have a phosphate group in the hydrophilic group portion thereof, and are compared with nonionic surfactants such as sucrose fatty acid esters and glycerin fatty acid esters. As a result, the water-insoluble mineral surface has a remarkably strong adsorption covering power. Therefore, a stable adsorption interface layer is formed on the surface of the fine particles of the water-insoluble mineral, and it is possible to effectively suppress the secondary agglomeration without peeling off even when subjected to the heat treatment. Dispersibility is obtained. Sufficient effects can be obtained even when the enzyme lecithin is used alone, but metal soaps such as sodium oleate, alkyl ether surfactants such as nonylphenyl ether, polyoxyethylene addition surfactants such as Tween, Sugar fatty acid esters, glycerin fatty acid esters, propylene glycol fatty acid esters and sorbitan fatty acid esters and other food emulsifiers, when used in combination with other surfactant components such as saponin compounds derived from Kiraya or Yucca foam,
A more favorable improvement in dispersibility is observed. The glycerin polymerization degree is 2 or more, preferably 3 to 10
When polyglycerol having a hydrophilicity of polyglycerin having a hydrophilic group of polyglycerin having a polymerization degree of 3 to 5 and a polyglycerin content of 70% or more is more preferably used, extremely suitable dispersibility can be obtained. The constituent fatty acids of the polyglycerin fatty acid ester are those having 6 to 22 carbon atoms, preferably 8 to 18, and more preferably 12 to 14 carbon atoms. Furthermore, by using one or more thickening polysaccharides selected from gum arabic, pectin, carrageenan, furceleran, guar gum, locust bean gum and xanthan gum in combination, there is no aggregation of water-insoluble minerals and further dispersibility is improved. Can be done. Similar effects can also be obtained by using a thickening polysaccharide such as crystalline cellulose or xanthan gum or a hydrophilic synthetic polymer such as polyvinyl alcohol or vinyl acetate copolymer. However, unless the enzymatically degraded lecithin treatment according to the present invention is performed in advance, good dispersibility in which secondary aggregation is suppressed cannot be obtained.

The method for adding the enzyme-decomposed lecithin in the present invention is not particularly limited as long as it is performed prior to the glycerin fatty acid ester and the thickening polysaccharide, but the enzyme-decomposed lecithin is dissolved in the aqueous metal salt solution. And a method of dispersing a metal salt in an aqueous solution of enzymatically decomposed lecithin. Foods containing the mineral composition according to the present invention include cookies, bread, secondary products of flour represented by noodles, processed rice products such as porridge and cooked rice, processed products such as livestock meat and fish meat, soft drinks, and milk. Drinks, carbonated drinks, drinks such as alcoholic drinks, and the like, and by allowing the addition of water-insoluble salts such as calcium phosphate and magnesium phosphate compositions to these, calcium, which tends to be insufficient, can be easily fortified with magnesium. It can be implemented. In particular, in liquid foods such as beverages, the addition of water-insoluble salts has a very narrow range of application due to the sedimentation of mineral components, but the present invention provides an excellent flavor and a chemically stable form. Can strengthen minerals. For example, in the food field, it is possible to produce a calcium- and magnesium-enriched beverage with good stability by preparing a calcium phosphate composition or a magnesium phosphate composition and adding it to beverages such as milk, lactic acid beverages, soft drinks, and carbonated beverages. it can.

The cosmetics containing the mineral composition of the present invention include lotions, emulsions, detergents such as bath agents and cleansing agents, dentifrices and the like. Damage to the bathtub due to precipitation of salts can be suppressed. Industrial products containing the mineral composition in the present invention, agricultural films,
Examples thereof include sheet materials for wall flooring and flame retardants for adding resin, and insoluble minerals such as calcium carbonate, barium sulfate, magnesium hydroxide, and zinc hydroxide are used. By stably dispersing these minerals in the resin base, it is possible to improve the physical strength after molding, the smoothness of the surface, and the functionality such as flame retardancy. Hereinafter, the present invention and its effects will be specifically described with reference to examples.
