Description

The present invention relates to a curdlan-containing composition containing curdlan, a product such as a food containing the curdlan-containing composition, and a method for producing a product such as a food containing the curdlan-containing composition.

Curdlan is used as a thickening polysaccharide mainly for improving physical properties such as thickening, gelling, water retention, and shape retention in various fields.

Curdlan is effective even when used as a powder, but since it is a water-insoluble substance, there is a problem that the function of curdlan cannot be fully exerted in the production of processed foods and the like.

In order to fully exert the effect of curdlan, there is a method of adding curdlan to water as a pretreatment and stirring it with a cutting mixer or a homogenizer to swell the curdlan and enhance the function of curdlan. , Equipment is required and it takes time and effort.

Instead of stirring with a cutting mixer or homogenizer, there is a method of stirring the curdlan in hot water at about 50 ° C to swell it and enhance the function of the curdlan, but the curdlan is added directly to the hot water at 40 ° C or higher. Then, since agglomerates (so-called "curdlan") are formed, it is necessary to add them to cold water and then heat them, which is also troublesome.

Unlike the above method, there is a method of swelling the curdlan using an alkaline agent, and this method does not require special equipment and can enhance the function of the curdlan with relatively little effort.

It is known that curdlan is used by alkaline swelling, and some inventions related thereto have been disclosed so far (see Patent Documents 1 to 3). On the other hand, there are few substances that show high alkalinity so that curdlan can swell and dissolve, especially in the case of foods. Sodium hydroxide and potassium hydroxide, which are generally used as alkaline agents, are deliquescent and inferior in handleability, so they are not suitable for compositions. Also, when using curdlan and sodium hydroxide or potassium hydroxide, use curdlan and sodium hydroxide or potassium hydroxide. Must be prepared separately. Phosphates such as trisodium phosphate and tripotassium phosphate may be used as the alkaline agent, but the use of phosphates may not be desired. Carbonates such as sodium carbonate and potassium carbonate may be used as the alkaline agent, but the pH does not rise as much as sodium hydroxide and trisodium phosphate, and the degree of swelling of curdran is lower than when the above substances are used. Become. Further, although there is a patent document that describes calcined shell calcium, calcined eggshell calcium, etc. as an alkaline agent for swelling curdlan (see Patent Documents 4 and 5), it is described in Examples described later that it contains a calcium salt. As shown in the reference example in the column, curdlan may precipitate without swelling and dispersing.

Therefore, when curdlan, which is difficult to dissolve in water, is dispersed or dissolved, a curdlan dispersion liquid or an aqueous solution can be easily prepared, and the function of curdlan can be fully exhibited, and the handleability is good. It is desired to develop a phosphate-free curdlan-containing composition.

Embodiments of the present invention will be described below. The present embodiment is an example of carrying out the present invention, and the present invention is not limited to the present embodiment.

The curdran-containing composition according to the embodiment of the present invention contains at least one of curdran, a calcium salt, and an organic acid salt and an inorganic acid salt, and is a dispersion obtained by dispersing or dissolving in water. Alternatively, the pH of the aqueous solution is 10 or more.

Alternatively, a curdran dispersion or an aqueous solution can be easily prepared when dissolved. With the curdlan-containing composition according to the present embodiment, curdlan having a low concentration to a high concentration can be easily dispersed or dissolved in water in a shorter time than the conventional method while maintaining the heat coagulation property and water retention of the curdlan. It becomes possible to make it. As a result, the function of the curdlan can be fully exerted, and the function of the curdlan can be maximized.

Curdlan has the property of forming a crosslinked gel by reaction with divalent ions such as calcium salt, and when curdlan is swollen or dissolved with high alkali, if divalent ions are present, it swells or Dissolution may not proceed sufficiently. The present inventors use a calcium salt as an alkaline agent, and by using at least one of an organic acid salt and an inorganic acid salt in combination, when the curdran is dispersed or dissolved in water, the curdran dispersion liquid or an aqueous solution is used. It was found that can be easily prepared. By using a calcium salt as an alkaline agent and using at least one of an organic acid salt and an inorganic acid salt in combination, a highly alkaline state can be achieved without using deliquescent sodium hydroxide or potassium hydroxide. Therefore, the curdran-containing composition is excellent in handleability. Further, since a highly alkaline state can be achieved without using a phosphate such as trisodium phosphate or tripotassium phosphate as an alkaline agent, a phosphate-free curdran-containing composition can be obtained. .. Compared with the case of using a carbonate such as sodium carbonate or potassium carbonate as an alkaline agent, a highly alkaline state is more likely to be obtained, so that a curdran dispersion or an aqueous solution can be easily prepared when dispersed or dissolved in water. can.

According to the curdlan-containing composition according to the present embodiment, in order to disperse the curdlan insoluble in water in advance, it is used in combination with a substance that imparts viscosity such as a thickening polysaccharide, or a high-speed stirrer or the like is used. No pretreatment is required, which simplifies the process of producing the curdlan dispersion or aqueous solution.

Hereinafter, the curdlan-containing composition according to the present embodiment will be described with reference to food and beverage uses, etc., but other uses other than food-related uses such as pharmaceuticals, industrial use, quasi-drugs, cosmetics, feed uses, etc. Also included.

The curdlan used in this embodiment is a heat-coagulable polysaccharide mainly composed of β-1,3-glucoside bonds produced by microorganisms. Examples of this polysaccharide include those produced by microorganisms of the genus Alcaligenes or Agrobacterium. Specifically, Curdlan is a strain of Alcaligenes faecalis var. Myxogenes 10C3K [Agricultural Biological Chemistry, Vol. 30, p196 (1966)], Alcaligenes faecalis var. Myxogenes strain 10C3K variant NTK-u (IFO13140), Agrobacterium radiobacter (IFO13127) and its variants U-19 It is a polysaccharide produced by (IFO13126). A commercially available curdlan may be used.

The pH of a dispersion or aqueous solution obtained by dispersing or dissolving the curdlan-containing composition according to the present embodiment in water, for example, 2% by weight of the curdlan-containing composition is dispersed or dissolved in water as the curdlan content. The pH of the obtained dispersion or aqueous solution is preferably 10 or more, preferably 11 or more, for example, in the range of 10 to 13, and more preferably in the range of 11 to 13. If the pH of the obtained dispersion or aqueous solution is less than 10, the liquid may not become a viscous liquid, and if it exceeds 13, the amount of acid required will increase if there is a subsequent neutralization step, which is not preferable. .. When the curdlan-containing composition is added to water as the curdlan content in an amount of 2% by weight, the curdlan is dispersed or precipitated in water when the pH is less than 11, and the curdlan is dissolved in water when the pH is 11 or more. Disperse or dissolve.

Examples of the calcium salt used in the present embodiment include calcined calcium such as shell calcined calcium (calcium salt containing 90% by weight or more of calcium oxide and containing calcium carbonate and the like), calcium oxide, calcium hydroxide, calcium carbonate, and dolomite. Examples thereof include inorganic calcium salts such as (CaMg (CO ₃ ) ₂ ) and organic calcium salts such as calcium salts of carboxylic acids such as calcium lactate, calcium citrate and calcium ascorbate. Of these, it is preferable to contain at least one of calcined calcium such as shell calcined calcium, calcium oxide, and calcium hydroxide from the viewpoint of good dispersibility and the ability to efficiently raise the pH of the solution. It is more preferable to contain calcined shell calcium from the viewpoint that waste can be used. The calcined shell calcium is obtained by calcining shells such as scallops at a high temperature (for example, 1000 ° C. or higher). The calcium salt may be used alone or in combination of two or more.

The pH of the aqueous solution obtained by dissolving the calcium salt used in the present embodiment in water is preferably 10 or more, and more preferably 11 or more. If the pH of the aqueous solution obtained by dissolving the calcium salt in water is less than 10, the curdlan may not swell sufficiently and may not be uniformly dispersed.

It will be possible to prepare a homogeneous dispersion or aqueous solution.

Examples of the organic acid salt include sodium acetate, trisodium citrate, disodium succinate, sodium gluconate, sodium ascorbate, sodium oxalate and the like. Of these, disodium citrate, sodium gluconate, and sodium oxalate are preferable, and sodium citrate is more preferable, from the viewpoint of good reactivity with calcium and the like. Of course, there is no problem even if the counterion of the organic acid salt is not limited to sodium but also potassium or the like.

Examples of the inorganic acid salt include sodium carbonate, sodium sulfate, sodium fluoride, sodium metaphosphate, sodium polyphosphate, orthophosphate and the like. Of these, sodium carbonate, sodium fluoride, sodium metaphosphate, sodium polyphosphate, and orthophosphate are preferable from the viewpoint of good reactivity with calcium.

In order to exert the effect of curdlan, the weight ratio to the calcium salt is preferably 0.5 or more, and more preferably 1 or more. If the content of at least one of the organic acid salt and the inorganic acid salt is less than 0.5 by weight with respect to the calcium salt, the curdlan may not be uniformly dispersed. There is no particular upper limit on the content of at least one of the organic acid salt and the inorganic acid salt in the curdlan-containing composition, but for example, it is 30 or less by weight with respect to the calcium salt.

In the curdran-containing composition according to the present embodiment, when the total weight of the curdran, the calcium salt, the organic acid salt and the inorganic acid salt is 100, the blending ratio of the curdran, the calcium salt, the organic acid salt and the inorganic acid salt is taken. The curdran is preferably in the range of 50 to 97.4, the calcium salt is preferably in the range of 1.3 to 5.0, and the organic and inorganic acid salts are preferably in the range of 1.3 to 45.
