Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery or granular paste prepared to exhibit viscosity or gelation by dissolving in water.

[0002]

2. Description of the Related Art Conventionally, many pastes have been used in foods and the like as thickening stabilizers. The size of the paste is usually powder,
It is commercially available as a dried product such as a plate or a thread, and is used after being dissolved in water or dissolved in hot water. In some cases, the glue is used for adjusting the viscosity of nursing foods and training foods for patients who have difficulty chewing and swallowing due to eating disorders.

[0003] However, it takes time and effort to dissolve these pastes, and depending on the pastes, the pastes may be limp or may be insufficiently heated to cause poor dissolution. Conversely, thermal decomposition may occur due to overheating. Therefore, it is not always easy for general consumers to use the paste.

[0004]

In order to prevent the formation of lumps, the paste can be formed into granules and containing a dispersant such as dextrin. Is required to be contained in a large amount (for example, 10 times or more of the thickener). When the dispersant is contained in a large amount, the amount of solid content increases, so that it takes time to dissolve, and the viscosity is slowly developed. Problem. In particular, when glue is used for adjusting the viscosity of nursing foods or training foods for patients who have difficulty mastication or swallowing due to eating disorders, it is necessary to dissolve easily without causing lumps and immediately develop viscosity. Is big.

[0005] In order to solve this problem, the present invention is capable of dissolving without forming lumps,
It is an object of the present invention to provide a powdery or granular paste capable of immediately developing viscosity.

[0006]

Means for Solving the Problems To achieve the above object, the present invention relates to a powdery or granular paste prepared to exhibit viscosity or gelation by dissolving in water, It is a powdery or granular paste characterized by containing at least one polysaccharide among gum arabic, pullulan, soybean polysaccharide and arabinogalactan.

As described above, according to the present invention, a powdery or granular paste prepared to exhibit viscosity or gelation by dissolving in water (hereinafter, referred to as "high-viscosity paste"). When used in combination with at least one or more polysaccharides of gum arabic, pullulan, soybean polysaccharide and arabinogalactan (hereinafter referred to as "low-viscosity polysaccharides"), It can be easily dissolved without causing immediate viscosity development.

Further, since the paste according to the present invention is in the form of powder or granules, unlike the paste in liquid form, it is stable over time, the processing step is simple, and it can be added to foods and the like. Even the taste of food does not fade. That is, an additive for thickening characterized by dissolving a paste in water to prepare a fluid liquid and adding it to a target substance containing water so as to develop viscosity or gelation (JP 2000-41
No. 594) can be dissolved in a short time without being heated and does not require heating when added to a target substance, so that desired viscosity and gelation can be obtained in a short time. However, since it is a liquid, it is not stable over time, and there is a problem that a processing step is complicated. Furthermore, since such a liquid paste is a liquid, there is a problem that the taste of the food to which the liquid paste is added becomes weak. Since the paste according to the present invention is formed in a powdery or granular form, such a problem is solved.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the content of the polysaccharide is preferably 10% by weight or more and 90% by weight or less, particularly preferably 30% by weight or more and 70% by weight or less. . When the content is less than 10% by weight, lump is liable to be generated, and when the content is more than 90% by weight, development of viscosity becomes slow even when dissolved in water.

In the present invention, the paste is guar gum, tamarind gum, locust bean gum, tara gum, guar gum, konjac mannan, sylum seed gum, sodium alginate, gellan gum, carrageenan, furcellane, pectin, starch, methylcellulose, carboxyl carboxyl. It is preferable that at least one of methyl cellulose, Azotobacter vinelandi gum and xanthan gum is contained.

The effect of the present invention that the above-mentioned effect of dissolving in water can be easily dissolved and thickened without disturbing when dissolved in water is that the solubility of the high-viscosity paste and the low-viscosity polysaccharide is high. It is thought to be due to the difference. That is, the dissolution rate of the polysaccharide is faster than the dissolution rate of the paste, and the dissolved polysaccharide slightly dissolves the paste to form lumps in the process of dissolving the powder paste. It is preventing.

The present inventors have confirmed this by the following experiment. First, gum arabic and soybean polysaccharide as low-viscosity polysaccharide, xanthan gum, guar gum and pectin 0.15 g of commercially available powder as high-viscosity paste, respectively.
1.5 g of glucose and 5 ml of purified water were added, and the solubility of each powder was observed over time. Table 1 shows the results.

[0013]

[Table 1]

As a low-viscosity polysaccharide, 0.2 g, 0.7 g, 1.6 g, 3.7 g, or 14.4 g of powdered gum arabic is mixed with 1.6 g of powdered xanthan gum to give glucose 8. 2.0 g and purified water 160 ml, and the viscosity of the xanthan gum was measured over time (gum arabic and xanthan gum were 1: 9, 3: 7,
A mixture of 5: 5, 7: 3, and 9: 1 was measured). In this measurement, the xanthan gum concentration was 1.0
% And adjust the viscosity to B after dispersion.
It was measured by a mold viscometer (manufactured by Shiba System Co., Ltd.).
The result is shown in FIG.

Table 1 shows that the dissolution rate of the low-viscosity polysaccharide is higher than that of the high-viscosity paste, and that the dissolved low-viscosity polysaccharide delays the dissolution of the high-viscosity paste from FIG. It can be seen that the polysaccharide alleviates the formation of lumps while the high-viscosity paste is dissolved in the liquid.

[0016]

Next, examples of the powdery or granular paste according to the present invention will be described. Example 1 First, as Example 1, a commercially available powdered gum arabic (manufactured by Sanei Pharmaceutical Trading Co., Ltd.) and a powdered xanthan gum (manufactured by Monsanto) were mixed at a ratio of 4: 6, and a fluidized bed granulator ( Ogawara Seisakusho), and granulated paste was granulated to a bulk specific gravity of 0.25.

When 2 g of the granular paste according to Example 1 was dispersed in 100 cc of water (distilled water at 20 ° C.), the viscosity developed and reached a stable viscosity in 30 seconds without causing lumps. The viscosity at this time was measured with a B-type viscometer (manufactured by Shibaura System Co., Ltd.).

Next, as Comparative Example 1, commercially available powdered dextrin (manufactured by Matsutani Chemical Industry Co., Ltd.) and powdered xanthan gum (manufactured by Monsanto Co.) were mixed at a ratio of 4: 6, and a fluidized bed granulator ( Ogawara Seisakusho), and granulated paste was granulated to a bulk specific gravity of 0.25. When 2 g of the granular paste according to Comparative Example 1 was dispersed in 100 cc of water (distilled water at 20 ° C.), it became lump and was not dissolved.

Next, as Comparative Example 2, commercially available powdered dextrin (manufactured by Matsutani Chemical Industry Co., Ltd.) and powdered xanthan gum (manufactured by Monsanto) were mixed at a ratio of 8: 2, and a fluidized bed granulator ( Ogawara Seisakusho), and granulated paste was granulated to a bulk specific gravity of 0.25.

In order to make the amount of the granular paste according to Example 1 equal to that of the high-viscosity paste, 6 g of the granular paste according to Comparative Example 2 was added to 100 cc of water (distilled water at 20 ° C.). When the dispersion was carried out, it took a long time to disperse due to the large amount of the solid content, but the dispersion finally did not result in lumps.

Further, the chronological expression of the viscosity of the granular paste according to Example 1 and the granular paste according to Comparative Example 2 was measured by a B-type viscometer. The result is shown in FIG. As shown in FIG. 2, it can be seen that the granular paste according to Comparative Example 2 requires 5 minutes for the viscosity to develop. The viscosity after 5 minutes was 1080 mPa · s.

As described above, the granular paste according to Comparative Example 1 tends to be lump when dissolved in water, and the granular paste according to Comparative Example 2 is dissolved without lump. However, it takes a long time for the viscosity to develop due to the large amount of solids, so it immediately develops viscosity as in the case of giving viscosity or coagulation to nursing and training foods for people with difficult mastication and swallowing It proves to be unsuitable for adjuvants that need to be effected.
On the other hand, the granular paste according to Example 1 can be easily dissolved in water without causing lumps,
The viscosity can be immediately expressed, indicating that it is suitable as an auxiliary agent that needs to immediately develop viscosity, such as when giving viscosity or coagulation to nursing and training foods for people with difficult mastication and swallowing .

Example 2 Next, as Example 2, commercially available powdery pullulan (manufactured by Hayashibara Shoji Co., Ltd.) and powdery guar gum (manufactured by Gokyo Sangyo Co., Ltd.) were mixed at a ratio of 3: 7, and a fluidized bed was prepared. Granular paste was granulated with a granulator (manufactured by Okawara Seisakusho) so as to have a bulk specific gravity of 0.35.

1.5 g of the granular paste according to Example 2
Was dispersed in 100 cc of water (distilled water at 20 ° C.). When the viscosity after 5 minutes was measured with a B-type viscometer (manufactured by Shibaura System Co., Ltd.), the viscosity was 620 Pa · s, which was a sufficient function as a feeding aid for patients who had difficulty in mastication and swallowing.

Next, as Comparative Example 3, a commercially available powdered dextrin (manufactured by Matsutani Chemical Industry Co., Ltd.) and powdered guar gum (manufactured by Gokyo Sangyo Co., Ltd.) were mixed at a ratio of 3: 7, and fluidized bed granulation was performed. Granular paste was granulated with a machine (manufactured by Okawara Seisakusho) to a bulk specific gravity of 0.35. When 1.5 g of the granular paste according to Comparative Example 3 was dispersed in 100 cc of water (distilled water at 20 ° C.), the paste became lump and could not be dissolved.

Next, as Comparative Example 4, a commercially available powdered dextrin (manufactured by Matsutani Chemical Industry Co., Ltd.) and powdered guar gum (manufactured by Gokyo Sangyo Co., Ltd.) were mixed at a ratio of 5: 5, and fluidized bed granulation was performed. Granular paste was granulated with a machine (manufactured by Okawara Seisakusho) to a bulk specific gravity of 0.25.

In order to make the amount of the granular paste according to Example 2 equal to that of the high-viscosity paste, 2.1 g of the granular paste according to Comparative Example 4 was added to 100 cc of water (distillation at 20 ° C.). When dispersed in water), it took a long time to disperse due to a large amount of solid content, but was finally dissolved without forming lumps.

Further, the chronological expression of the viscosity of the granular paste according to Example 2 and the granular paste according to Comparative Example 4 was measured by a B-type viscometer. The result is shown in FIG. As shown in FIG. 3, it can be seen that the granular paste according to Comparative Example 4 requires 5 minutes for the viscosity to develop. The viscosity after 5 minutes was 480 mPa · s.

As described above, the granular paste according to Comparative Example 3 tends to be lump when dissolved in water, and the granular paste according to Comparative Example 4 is dissolved without lump. However, it takes a long time for the viscosity to develop due to the large amount of solids, so it immediately develops viscosity as in the case of giving viscosity or coagulation to nursing and training foods for people with difficult mastication and swallowing It proves to be unsuitable for adjuvants that need to be effected.
On the other hand, the granular paste according to Example 2 can be easily dissolved in water without causing lumps,
The viscosity can be immediately expressed, indicating that it is suitable as an auxiliary agent that needs to immediately develop viscosity, such as when giving viscosity or coagulation to nursing and training foods for people with difficult mastication and swallowing .
