Specific description of the invention

The binder for granulation of the present invention contains, as active ingredients, one or both of a resistant glucan and a processed product thereof. In addition, the production method of the present invention is characterized by using either or both of the indigestible glucan and its processed product as a binder for granulation.

In the present invention, "indigestible glucan" means indigestible glucan (glucose polymer). The indigestible glucan of the present invention comprises a sugar condensate obtained by subjecting a starch degradation product of DE 70 to 100 to condensation reaction by heat treatment.

A starch hydrolyzate having a DE of 70 to 100 can be used as the starch hydrolyzate which is a raw material for the indigestible glucan. The starch hydrolyzate may be, for example, a starch hydrolyzed with an acid or an enzymatic hydrolyzate. Here, "DE (Dextrose Equivalent)" is an index of the degree of degradation of starch hydrolyzate, and is a value expressed as a percentage of the solid content, with the reducing sugar in the sample being glucose. The DE of the starch hydrolyzate can be measured, for example, by the Lane-Eynon method. The starch hydrolyzate used as a raw material for the indigestible glucan preferably has a DE of 75-100, more preferably 80-100.

The "degraded starch having a DE of 70 to 100" used in the present invention may be any starch hydrolyzate having a DE that satisfies a predetermined range, and examples thereof include malto-oligosaccharide, starch syrup, starch syrup, and glucose. There are no particular restrictions on its properties, and it may be a crystalline product (anhydrous glucose crystal, hydrated glucose crystal, etc.), a liquid product (liquid glucose, starch syrup, etc.), or an amorphous powder product (powder candy, etc.), but handling and manufacturing costs are acceptable. Considering the above, it is preferable to use a liquid product. In particular, the use of glucose syrup called "hydrol", which is a by-product produced in the glucose refining process, is extremely advantageous from the viewpoint of recycling and raw material cost reduction.

In the present invention, "heat condensation" refers to condensing a starch decomposition product under heating conditions, and the heat condensation method is well known to those skilled in the art. The heating conditions in the heat condensation are not particularly limited as long as the indigestible glucan of the present invention is obtained by the condensation reaction, and a person skilled in the art can appropriately determine the heating conditions. It is preferable to heat so that the dietary fiber content of the condensate) is 70% or more, for example, heat treatment at 100 ° C. to 300 ° C. for 1 to 180 minutes, more preferably 150 ° C. to 250 ° C. for 1 to 180 minutes. By doing so, the indigestible glucan of the present invention can be produced.

Examples of heating equipment used in the thermal condensation treatment include shelf hot air dryers, thin film evaporators, flash evaporators, vacuum dryers, hot air dryers, steam jacket screw conveyors, drum dryers, extruders, worm shaft reactors, kneaders and the like.

If the reaction is carried out under reduced pressure conditions, it is advantageous in that the degree of coloration of the reaction product is reduced.

In the present invention, the heat-condensation treatment may be carried out under non-catalytic conditions, but is preferably carried out in the presence of a catalyst from the viewpoint of the reaction efficiency of the condensation reaction. The catalyst is not particularly limited as long as it catalyzes the sugar condensation reaction. Examples include inorganic acids such as hydrochloric acid, phosphoric acid, sulfuric acid, and nitric acid; Mineral substances such as acid, diatomaceous earth, activated clay, acid clay, bentonite, kaolinite, and talc, and activated carbon such as steam carbon, zinc chloride carbon, sulfonated activated carbon, and oxidized activated carbon can be used. Considering the coloring, safety, taste and smell of the resulting water-soluble dietary fiber material, it is preferable to use activated carbon as the catalyst. Two or more of the above catalysts may be used in combination.

As the indigestible glucan used in the present invention, the indigestible glucan obtained by the above method may be used as it is. Various processed products of the indigestible glucan (referred to herein as "processed products") may be used. Processed products of indigestible glucan include, for example, indigestible glucan enzyme-treated products, indigestible glucan fractionated products, and indigestible glucan reduced products.

In the present invention, the "enzyme-treated product of indigestible glucan" can be obtained by enzymatically treating indigestible glucan with a glycolytic enzyme.

In the present invention, the term "carbolytic enzyme" means an enzyme that acts on carbohydrates and catalyzes their hydrolysis reaction. - glucosidase, cyclodextrin glucanotransferase, β-glucosidase, β-galactosidase, β-mannosidase, β-fructosidase, cellobiase, gentiobiase. Carbohydrate-degrading enzymes may be used singly or in combination of multiple enzymes. α-Amylase and glucoamylase are preferred from the standpoint of degrading into indigestible glucan, and although either of the two enzymes may be acted alone, α-amylase and glucoamylase are particularly preferably acted together.

In the present invention, the conditions for the glycolytic enzyme treatment are not particularly limited as long as the easily digestible portion of the indigestible glucan is digested by the enzyme treatment, and a person skilled in the art can appropriately determine the enzyme treatment conditions. However, the enzyme treatment is preferably performed so that the glucose content per solid content is increased by 1% by mass or more, more preferably by 2% by mass or more, for example, at 20 to 120 ° C. for 30 minutes to 48 hours, more preferably. can be enzymatically treated at 50-100° C. for 30 minutes to 48 hours.

In the present invention, the "fractionated product of resistant glucan" can be obtained by fractionating resistant glucan and/or its enzymatically treated product. It is obtained by fractionation treatment using a fractionation means such as membrane separation or gel filtration chromatography to remove carbohydrates with a specific degree of polymerization. In addition, by increasing the dietary fiber content, the value as dietary fiber and the physiological function derived from dietary fiber can be enhanced. This "fractionation treatment" can be carried out so that the content of disaccharides and below is 15% by mass or less, preferably 10% by mass or less, more preferably 5% by mass or less, based on the solid content.

In the present invention, when preparing a small amount of sugar alcohol, the method using a hydride reducing agent is simple and convenient because it does not require special equipment. For this, the method using a catalytic hydrogenation reaction is preferable because it is economical and produces few by-products. A "catalytic hydrogenation reaction" is a reaction in which hydrogen is added to a double bond of an unsaturated organic compound in the presence of a catalyst, and is generally called a hydrogenation reaction. By carrying out the reduction treatment, the indigestible glucan used in the present invention and its processed products can be reduced in coloration, the stability against acids and alkalis can be improved, the browning reaction due to heating, and the Maillard reaction with amino acids and proteins can be performed. You can suppress the reaction.
