Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing an instantly thickened and gelled material.

[Prior Art] Heating at 90 ° C. or higher was necessary to prepare an aqueous solution of gellan gum in order to form a gelled substance by using gellan gum to increase the viscosity.

Therefore, equipment for heating to a high temperature and maintaining the temperature is required, and cooling equipment is required for thickening and gelling.

[Means for solving the problem]

The present invention provides gellan gum by physically pulverizing gellan gum to increase the dissolution rate of gellan gum.
Fine particles of 150 μm or less. Preferably, the particle diameter is 75 μm or less.

Mix the sequestering agent with the fine gellan gum,
This aqueous solution is immediately thickened and gelled by stirring for 30 to 60 seconds in addition to ordinary water.

Examples of sequestering agents include polymerized phosphates, for example, acidic, neutral, and basic sodium salts such as metaphosphoric acid, polyphosphoric acid, and pyrophosphoric acid.

There are also acidic, neutral and basic sodium salts such as citric acid, tartaric acid, fumaric acid, ethylenediaminetetraacetic acid and other organic acids. Organic compounds such as phytic acid, tannic acid and gentisic acid, and others are also included. The amount of addition of these sequestering agents is 10
The amount is 1 to 200 parts with respect to 0 parts, but is not limited to this range.

As a method for forming fine particles, any method such as ball mill pulverization, hammer mill pulverization, Nara pulverization, and feather mill pulverization may be used as long as the particle diameter of gellan gum is 150 μm or less, and is arbitrary.

The mixture of the finely divided gellan gum and the sequestering agent thus obtained is soluble in cold water. For example, 20
When tap water at ℃ is used, it is dissolved by stirring for 30 to 60 seconds to obtain a viscous aqueous solution.

Acidic, neutral and basic metal salts such as alkaline earth metal salts such as Ca and Mg, alkali metal salts such as K and Na, ammonium salts, aluminum salts and the like are used in combination with the fine particle gellan gum and the sequestering agent. You may.

It is desirable that these salts have a lower dissolution rate in water than gellan gum of fine particles and a sequestering agent. For example, alkaline earth metal salts calcium sulfate (magnesium), phosphoric acid 1,2,3 calcium (magnesium), mono-, di-, tricalcium (magnesium) citrate, calcium gluconate, calcium carbonate or bicarbonate (magnesium), etc. Acid salts, neutral salts, or basic salts, or alkali metal salts of monocitrate, di,
Sodium (potassium), tartaric acid, fumaric acid, mono- or dipotassium (sodium) of adipic acid, potassium acid metaphosphate (sodium), sodium (potassium) pyrophosphate, acid salts of inorganic acids and organic acids such as potassium monophosphate, As a neutral salt, basic salt, ammonium or aluminum salt, it gradually hydrolyzes in water like monoammonium phosphate, dehydrated and dried ammonium alum, alum or glucono delta lactone to become an acidic substance. You may use together.

The addition amount is desirably 1 to 300 parts with respect to 100 parts of the mixture of the fine particle gellan gum and the sequestering agent. Of course, it is not limited to this range.

In addition, even if the metal salt is soluble in water, the particle size may be increased, or the surface of the metal salt may be coated with a hardly soluble substance to increase the dissolution rate. A mixture of gellan gum, a metal salt, fine particles of gellan and a sequestering agent, added with ordinary water or cold water and stirred for 30 to 60 seconds to instantaneously thicken and gel (rapid-effect type), and gradually gel Stuff (slow effect) is obtained. The rate of these thickening and gelling can be freely adjusted by the selected metal salts and the ratio of addition. In addition, when glucono delta lactone is added, it has a delayed effect.

Further, water is added to and dissolved in a mixture of the particulate gellan gum and the sequestering agent, and the resulting aqueous solution is treated with an alkali metal salt, an alkaline earth metal salt, ammonium, an inorganic salt of an aluminum salt, an organic acid or an acid salt, Basic salts, basic salts may be added, or substances containing the same, such as carbonated beverages, coffee, tea, milk, juice, wine, sake, brandy, yogurt, acerola juice, etc.
By mixing, an instantly thickened gelled substance can be obtained.

〔The invention's effect〕

 Hereinafter, the effects of the present invention will be proved by experimental examples.

Experimental Example 1 The following stabilizer was added while stirring normal water, and dissolved by stirring for 30 to 60 seconds, followed by cooling in a refrigerator (5 ° C.) for 1 hour.

Viscosity: using a B-type rotational viscometer Rotor # 2 Rotational speed 60 rpm Gel strength: Measured with a model 301 of Iio Electric Co., Ltd.

Example 1 Gellan gum was pulverized with a ball mill to a particle size of 75 μm.
0.4 parts of gellan gum and 0.1 part of sodium metaphosphate were added to 100 parts of water (10 ° C.) and stirred for 30 seconds to form a transparent viscous solution. The viscosity at this time is
240 cps.

As a control, 0.4 part of gellan gum and 0.1 part of sodium metaphosphate were added to 100 parts of water (10 ° C.), and the mixture was stirred for 30 seconds. As a result, insoluble particles of gellan gum were suspended to form a cloudy liquid. The viscosity of this aqueous solution was 15 cps. As a result, the fine gellan gum of the present invention can be easily dissolved in water (10 ° C).
It was found to dissolve in.

Similar results were obtained when phytic acid and sodium citrate were used instead of sodium metaphosphate.

Example 2 Fine Particulate Gellan Gum 0.4 Part, Sodium Metaphosphate
A mixture of 0.1 part of 0.05 part of calcium sulfate mixed with water (1
(0 ° C.) and stirred for 30 seconds. The mixture was left at 25 ° C. for 5 minutes to gel. The gel strength at this time was 200 bloom when measured by a bloom gelometer. On the other hand, 0.05 part of calcium sulfate and water (10
° C) and stirred, but did not gel.

Example 3 Fine Particulate Gellan Gum 0.4 Part, Sodium Metaphosphate
A mixture of 0.1 part of glucono delta lactone and 0.2 part of glucono delta lactone was added to 100 parts of water (10 ° C.), stirred for 30 seconds, and left at 25 ° C. for 30 minutes to form a transparent gel. The gel strength at this time was 175 bloom.

Example 4 0.4 parts of fine gellan gum, sodium metaphosphate
0.1 part was added to 100 parts of water (10 ° C.) and stirred for 30 seconds. To the dissolved liquid, 10 parts of fruit juice, 30 parts of milk, 20 parts of sake, 20 parts of wine, 20 parts of brandy, and 0.1 part of citric acid were added and mixed for 10 seconds. However, it gelled.
