Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is directed to a liquid glue preparation, in which a glue such as xanthan gum or guar gum, which is widely used in the food industry, is dispersed in a liquid. The present invention relates to a thickening liquid agent, and particularly to a thickening liquid agent having extremely good solubility and excellent workability.

<Prior art> Xanthan gum, guar gum, gum arabic, tamarind gum, locust bean gum, carrageenan, sodium alginate, CMC (carboxymethyl cellulose)
Natural or synthetic thickeners, such as these, are widely used in the food industry for the purpose of improving the physical properties of foods, such as body feel and tactile sensation during eating and drinking, and improving the monolithic properties of foods. ing.

Usually, these glues are in powder form, and when used, the powder is dissolved in water or an aqueous solution such as liquid food. However, since glue powders generally have very high hydration properties, when they are dissolved in water, they often form aggregates of glue called ``Mamako.'' When it occurs, it becomes extremely soluble and workability is significantly reduced. Therefore, severe stirring conditions are generally required when dispersing and dissolving the thickening powder, but some thickening agents are still susceptible to "stickiness" even under such stirring conditions. Thickening agents that tend to cause "mamako" include those that have particularly high hydration properties with water, such as xanthan gum, sodium alginate, guar gum, and CMC. In order to do this, the following methods have conventionally been adopted.

The first method is to use water-soluble powder such as sugar or glucose. ! This is a method in which the mixed powder is diluted in advance as a solid amount by mixing it with a similar powder, and the mixed powder is poured into water. Although this method is an excellent method for preventing the occurrence of "mamako", it requires mixing the paste powder and the W-type powder on site, which increases the extra process of so-called premixing and reduces the work time. The problem is that it becomes complicated.

Next, as a second method, attempts have been made to improve the dispersion and solubility by granulating or coarsening the paste, but this increases the cost and prevents the occurrence of "mamako". Even if this can be prevented, there are still problems such as it takes time for the paste to dissolve completely.

Furthermore, as a third method, there is a method in which the size powder is uniformly suspended in an alcohol that is liquid at room temperature, such as ethyl alcohol, and the liquid is poured into water to dissolve the size powder. However, the thickening agent in the alcohol solution is not dissolved, but merely suspended, and is extremely prone to sedimentation. (within) will settle. For this reason, it is difficult to separate and add a predetermined amount of paste, and when adding it, it is necessary to mix it with a stirrer, that is, to maintain a uniform suspension state before adding it to the water. This method is complicated in that it is not possible to prevent the occurrence of water, and also in this case, a premix operation of mixing the paste powder into the alcohol solution is required.

As described above, all of the above-mentioned conventional techniques have problems in terms of workability, and improvements in this respect have been highly desired by the paste users.

One possible means to satisfy such a demand is to manufacture a thickening liquid by dissolving thickening powder in water at a high concentration, and distribute the liquid as a product. However, when a thickening agent is dissolved in water, the viscosity of the solution increases as the concentration of the thickening agent increases, and eventually the viscosity becomes so high that even stirring is difficult. Therefore, the concentration of the glue that can be dissolved in water is extremely low, at most 1 to 2%, and the aqueous solution is highly perishable, making it difficult to store. It is difficult to commercialize a thickening agent.

<Problems to be Solved by the Invention> The present invention was made in view of the above circumstances, and is a liquid glue preparation, that is, a glue liquid, which is extremely excellent not only in solubility but also in workability. Moreover, it is an object of the present invention to provide a thickening agent which contains a thickening agent at a high concentration and is resistant to spoilage.

Means for Solving the Problems> In order to achieve the above object, the present inventors have made extensive studies and found that a partially hydrated water-alcohol dispersion of the glue dissolves the glue. It has been found that it is extremely effective in improving properties and workability, and that it is also possible to contain thickening powder at a relatively high concentration.

The present invention was made based on this knowledge, and is characterized by dispersing thickening agent powder such as xanthan gum, guar gum, sodium alginate, etc. in a water-alcohol mixed solution to form partially hydrated particles of the thickening agent. This is a liquid glue agent.

Effect> When the size powder is dispersed in a mixed solution of water and alcohol, the particles of the size partially hydrate with water to form partially hydrated particles, and due to the formation of the partially hydrated particles, Viscosity is imparted to the dispersion. The viscosity of the resulting dispersion is mainly determined by the degree of hydration (degree of hydration) of the partially hydrated particles formed, and when the degree of hydration is high, the viscosity of the dispersion becomes high;
When the degree of hydration is low, the viscosity is also low.

The degree of hydration of the partially hydrated particles formed depends mainly on the alcohol concentration in the water-alcohol mixed solution used; the lower the alcohol concentration, or in other words, the higher the proportion of water, the degree of hydration. The higher the alcohol concentration, the higher the viscosity of the dispersion. Conversely, the higher the alcohol concentration, the lower the viscosity of the dispersion.

In other words, by appropriately adjusting the alcohol concentration of the water-alcohol mixed solution in which the thickening powder is dispersed, the viscosity of the resulting dispersion can be controlled to a certain extent.
Under appropriate alcohol concentration conditions, even if the thickening agent powder is dispersed at a high concentration, the fluidity of the liquid can be prevented from being impaired. Further, by adjusting the viscosity of the dispersion liquid to an appropriate viscosity, it becomes possible to maintain the formed partially hydrated particles in a stable dispersed state.

As can be seen from the above explanation, by setting the alcohol concentration of the water-alcohol mixed solution to be used within an appropriate range, it is possible to contain the thickening powder in a high concentration and reduce the viscosity of the liquid to such an extent that it loses its fluidity. It is possible to obtain a dispersion liquid having a moderate viscosity so that the partially hydrated particles formed are maintained in a stable dispersion state for a long period of time.

The liquid glue of the present invention is a liquid glue preparation made by dispersing glue powder such as xanthan gum or sodium alginate in a water-alcohol mixed solution with an optimal alcohol concentration that satisfies the above-mentioned conditions. It contains a thickening agent at a high concentration of, for example, 5 to 10%, or even higher depending on the type of thickening agent, and has fluidity, and the stability of the partially hydrated particles of the thickening agent is, for example, 1 to 7 days. Or it is a glue solution that can be maintained for a longer period of time.

Since the thickening agent of the present invention is a uniform dispersion of the thickening agent, there is no need to measure it while stirring, and therefore, the measuring operation is simple, and one type of agent can be measured. Since the desired aqueous paste solution can be obtained by simply adding it, the dissolution work is extremely time consuming.

The above optimal alcohol concentration range varies greatly depending on the type of alcohol and glue used.
The optimal concentration range must be determined for each individual case, but if the alcohol concentration is too high, the degree of hydration of the partially hydrated particles formed will be insufficient and the viscosity of the liquid will be too high. As a result, the partially hydrated particles easily settle, making it impossible to maintain a stable dispersion state.Also, if the alcohol concentration is lower than the optimum concentration, hydration progresses too much and the liquid The viscosity of the product becomes too high, resulting in loss of fluidity and difficulty in handling.

In addition, the above-mentioned moderate viscosity that maintains the partially hydrated particles of the thickening agent in a stable dispersion state and does not impair fluidity varies depending on the type of alcohol used and the type of thickening agent, but for example, Type B The viscosity measured with a rotational viscometer (rotation speed 6 rpm) is approximately 500~? It is in the range of 0.0OOcp.

Regarding the dispersion stability of the thickening liquid of the present invention, when distributing the thickening liquid as a product, it is desirable to maintain it for as long as possible (for example, one week or more). In the case where the product is produced and consumed within a short period of time, it is sufficient to maintain a uniformly dispersed state for, for example, 1 to 2 days.

Thickening agents that can be used in the present invention include all types of thickening agents that are approved as food additives, but are particularly used for thickening agent powders that are extremely prone to becoming sticky, such as xanthan gum, sodium alginate, CMC, and guar gum. Then it is optimal.

In addition, the alcohol used in the present invention may be used at room temperature (1
Any alcohol may be used as long as it is liquid at a temperature of 0 to 30°C and is approved for addition to foods, such as ethyl alcohol, glycerin, propylene glycol, and the like. In addition, sugar alcohols such as sorbitol (usually in powder form) may be used in combination with these alcohols.

In addition, soluble substances commonly used in foods, such as sugars, salt, organic acids, seasonings, or flavors, may be dissolved in the thickening agent of the present invention.

When producing the liquid glue of the present invention, first prepare a water-alcohol mixed solution with an alcohol concentration within the optimum concentration range, and add a predetermined amount of glue powder to the mixed solution while stirring. Although it may be manufactured by dispersing, from the viewpoint of more uniformly dispersing the partially hydrated particles of the thickening agent formed in the liquid, it is easier to manufacture by the following method.

For example, it is best to put the thickening powder into an industrially obtained high-purity alcohol solution, stir it to uniformly disperse the thickening powder, and gradually add a predetermined amount of water to adjust the alcohol concentration to the optimum range. , such a method is also useful in determining the optimal alcohol concentration range.

Effects> Examples will be shown below to make the effects of the present invention more clear.

Example 1 100 g of xanthan gum powder was added and dispersed in 500 g of anhydrous ethyl alcohol solution with stirring, and a predetermined amount of water was gradually added while stirring.

Six types of xanthan gum dispersions were prepared by setting the amount of water to be added in six stages in the range of 400 to 550 g. Table 1 shows the results of examining the quality characteristics of the obtained dispersion.

Table 1 As shown in Table 1, as the amount of water added increases, that is, as the alcohol concentration decreases, the viscosity of the resulting dispersion increases, and the partially hydrated xanthan gum particles sediment accordingly. It's getting harder.

However, in the case of Kan6 dispersion, which has the lowest alcohol concentration of 43.5%, the viscosity is too high (over 100,000 yen), and it becomes a viscous, almost non-flowable, and heterogeneous sol. Therefore, it exhibits properties that cannot be described as liquid, and has poor solubility, making it unsuitable as a thickening agent.

In addition, in the case of magnetic 1 to 11kk3 dispersions with alcohol concentrations in the range of 50% to 46.1%, the viscosity of the dispersion is insufficient, and the partially hydrated particles formed can be dissolved in a short period of 5 to 30 minutes. It settles within a certain period of time, and in this case, it is also unsuitable as a thickening agent.

On the other hand, in the case of the positive 4 dispersion with an alcohol concentration of 45.5%, a uniform dispersion state was maintained for 3 days, and furthermore, in the case of the magnetic 5 dispersion with an alcohol concentration of 45.0%, a uniform dispersion state was maintained for 7 days. It maintains a uniform dispersion state even after evaporation, has easy-to-handle fluidity, has extremely good solubility, and has a xanthan gum content of 9.1%.
It is as high as 9.0%, making it ideal as a glue liquid. Furthermore, in the case of NcL5 dispersion, it can be sufficiently distributed as a product.

Example 2 100 g of sodium alginate powder and 500 g of anhydrous ethyl alcohol solution were used, and the amount of water added was 1
．． Four types of sodium alginate dispersions were prepared in the same manner as in Example 1, with four levels set in the range of 100 to 1.400 g. Table 2 shows the results of examining the quality characteristics of the obtained dispersion.

As is clear from Table 2, except for the 1lh1 dispersion, which is unfavorable in terms of sedimentation, any of the dispersions NlX2 to 4 can be used as a thickening agent.

Moreover, from the above results, it can be said that an ethyl alcohol concentration in the range of approximately 25 to 28% is optimal in this case.

Example 3 100g of guar gum powder and 20g of propylene glycol liquid
0g and the amount of water added is 1.000 to 1.
, 600 g, and four types of guar gum dispersions were prepared in the same manner as in Example 1. Table 3 shows the results of examining the quality characteristics of the obtained dispersion.

As is clear from Table 3, any of the dispersions obtained in this case can be used as a thickening agent, especially Kan 3-3.
Kan4 dispersion has sufficient dispersion stability to be used as a product. Therefore, in this case, a propylene glycol concentration in the range of approximately 10 to 16% is optimal.

In addition, in the case of guar gum, the viscosity is 54.0OOcp, 65.0Ocp, etc.
Even at an extremely high viscosity such as OCp, it had fluidity that was easy to handle.

As explained above, the present invention utilizes a novel and unprecedented technical means of dispersing the thickening powder in a water-alcohol mixed solution to form partially hydrated particles of the thickening agent. This makes it possible to achieve a high concentration of the thickening material while maintaining the fluidity of the liquid, which would not be possible if the thickening agent is dissolved in a liquid. , which utilizes the viscosity of the liquid brought about by partial hydration to maintain stability over a long period of time.

In the thickening agent of the present invention, the thickening agent forms partially hydrated particles and maintains a stable and uniform dispersion state, so the solubility of the thickening agent when added to water is extremely good. In addition, it is extremely easy to work with, as it does not require any extra steps such as premixing, and can be dissolved simply by measuring the required amount of liquid and adding it to water.

Furthermore, since the liquid glue of the present invention contains alcohol as a component, the bacteriostatic or bactericidal action of the alcohol makes it possible to provide a liquid glue with a small number of viable bacteria, and it does not spoil even if stored for a long time. It has the advantage of being prevented.
