2. Description of the Related Art "Plantago Obata Sue" is a dry powder of a psyllium Psyllium (seed coat) of a plant called PLANTAGO OVATA FORSKAL from India, which has strong water absorption and swelling action, diffusion inhibition action and adsorption action. It has properties such as an intestinal action, a blood sugar level suppressing action, and a blood lipid regulating action. For this reason, plantago obata powder has long been used as a constipation drug, laxative or antidiarrheal, and has recently been used as a raw material for eyewash and facial packs for relieving eye pain. In addition, the chemical structure of plantago-obata powder is composed of highly branched granular polysaccharides with xylan as the main chain, and the side chain contains arabinose, xylose, galacturonic acid, and rhamnol, so it is used as a food fiber material. Has also attracted attention.

[0003] However, the end of Plantago Obata is
Due to its strong water absorption and swelling action, the viscosity becomes too high when an aqueous solvent is added during formulation to make it into an aqueous solution, and if it is taken together with saliva, it causes discomfort such as adhesion to the oral cavity Sometimes. As a method of producing such granulated plantago obata powder, which avoids such unpleasant texture and is easy to produce and take, for example,
After mixing plantago / obata powder and water-soluble dietary fiber with thickening polysaccharides and excipients, adding an organic solvent such as ethanol in an amount of 15% to all raw materials, and further adding and mixing water 20% Crushing to obtain flake granules;
Add organic solvent or mixed solvent of water and organic solvent to a mixture of plantago / obata seed coat and organic solvent containing water-soluble polymer soluble in organic solvent (70-100% by weight based on all raw materials) After kneading and kneading, granulation (JP-A-64-90130);
A method has been proposed in which saccharides are attached to the surface of an obata seed coat by stirring granulation in the presence of an aqueous solvent to obtain flake-like granules (Japanese Patent Application Laid-Open No. 173068/1995). Here, the above method is a well-known method in the art.

[0004] However, in the above method, the use of a large amount of organic solvent increases raw material costs;
After that, a large amount of organic solvent evaporates during drying, which makes the manufacturing environment worse; and furthermore, plantago obata powder generally absorbs a large amount of aqueous solvent due to its high water absorption, so that granulated granules are obtained. Takes a long time to dry,
There is a problem. Furthermore, the obtained flake-like granules have a bad tongue when taken due to their shape, and easily adhere to teeth and the oral cavity. The water-soluble polymer soluble in the organic solvent used in the above method may be one that can be used only for pharmaceuticals, and the obtained granules are used other than pharmaceuticals, for example, as foods or food additives. There are things you can't do. In the above method, since the surface of the plantago / obata powder is coated with a relatively large amount of saccharides, the content of the plantago / obata powder in the final granule is small. In addition, since saccharides are easily dissolved in saliva, the effect of suppressing adhesion to the oral cavity during ingestion cannot be sufficiently obtained.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide granules containing dietary fiber by a granulation method, and in particular, the amount of an organic solvent used can be reduced.

As a result, a reply was obtained that the granules obtained in Example 1 were improved in the following points as compared with the granules of Comparative Example 1. Oral adhesion: 71% of panelists answered that they had been improved. -Tongue: 79% of panelists answered that they had improved. -Ease of drinking: 71% of panelists answered that they had improved.

Comparative Example 2 Extrusion granulation was attempted in the same manner as in Example 1 except that no edible oil and fat and no emulsifier were used. 1.5 mm or less could not be achieved. When the obtained granules were taken by five panelists, they were found to adhere to the oral cavity and cause problems such as texture and ease of drinking.

Comparative Example 3 11% by weight of an aqueous sorbite solution having a solid content of 70% by weight
Extrusion and granulation were attempted in the same manner as in Example 1 except that the amount of water was changed to 5.5% by weight. However, granulation was not successful, and the obtained small amount of granules had a particle size of 1.5 mm or less. I could not achieve it. When the obtained granules were taken by five panelists, they were found to adhere to the oral cavity and had a problem with tongue feel and ease of drinking.

[0033]

According to the present invention, it is possible to greatly reduce the amount of an organic solvent used in a method widely applicable to foods. By adding an aqueous binder after impregnating the dietary fiber-containing raw material with the oily binder, it is possible to suppress the penetration and absorption of water into the plantago and obata powder, thereby enabling extrusion granulation of a composition having a high dietary fiber content. And the drying time of the granules after granulation can be greatly reduced. The granules containing the dietary fiber of the present invention are not flakes but granules having an average particle size of 1.
Since it is provided in a size of 5 mm or less, it does not adhere to the oral cavity, and the texture, such as texture and ease of drinking, has been greatly improved.
