Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

[0002] The present invention relates to a sugar-free coated preparation and a method for producing the same.

[0003]

[Prior art]

[0004] Coating preparations are formed by forming a film on the surface of a core material containing food or medicine, thereby reducing the quality deterioration such as moisture absorption, oxidation and photolysis of the core material, and reducing the bitterness, smell, It plays a role in relieving irritation, etc.
As a typical example, a coating technique for forming a carbohydrate film is well known.

[0005] Sugars used for coating include, for example,
As introduced in JP-A-49-108225 and the like, use of sugar has been the mainstream.

[0006] However, a coating method using a sugar other than sugar is desired from the viewpoint of sugar intake restriction such as diabetes and the viewpoint of caries prevention, and a coating using a sugar alcohol has been proposed. Among them, those using maltitol are introduced as having excellent properties in Japanese Patent Publication No. 7-55898, Japanese Patent Publication No. 2793283, and the like.

[0007] The method disclosed in Japanese Patent Publication No. 7-55898 uses maltitol instead of sugar in order to solve the caries property of the prior art using sugar, and reduces breakage and cracking. To do so, a reinforcing agent such as pullulan or gums is used in combination.

The method disclosed in Japanese Patent Publication No. 2793283 is different from the method disclosed in Japanese Patent Publication No. 7-55898 in that the adhesion of the core agent due to the adhesiveness of maltitol and the reinforcing agent and the coating pan coating. This method has been proposed as a solution to such a problem because there is a problem in workability due to the adhesion, there is a problem that the deformation is apt to occur, and furthermore, a disintegration rate of the coating layer is slow.

The technical content is that 1.5 to 3.0 parts by weight of a suspending base is used per 1 part by weight of maltitol, and silicon dioxide is used as a disintegrant to promote the disintegration of the coating layer. It was that.

[0010]

[Problems to be solved by the invention]

However, the prior art still has a problem to be solved. For example, when coating is carried out within the range proposed in Japanese Patent Publication No. 7-55898, most of the coating material to be applied to the core does not adhere to the core and comes into contact with the coating pan, and A large amount of coating material adheres to the inside of the bread and solidifies as it is, so there is a lot of loss of coating material and it is difficult to clean the coating pan after coating work.
There have been problems such as the mutual adhesion of the core agents, the deformation of the preparation, the resulting coating preparation being too hard, and the disintegration rate of the coating layer being too slow.

In the method disclosed in Japanese Patent Publication No. 2793283, the core agent absorbs moisture unless the thickness of the coating layer is considerably increased, and the coating preparation obtained by the coating layer is fragile and fragile. Cracks are apt to occur, and there are problems such as strong discomfort, foreign body sensation, and powderiness in the mouth when taking, and problems such as difficulty in obtaining a practical coating formulation. There was a point.

Further, as a result of additional testing of the prior art, there is a problem that a large variation occurs in the maltitol crystal formation rate during coating, which makes it extremely difficult to control the process, thereby making it impossible to automate the coating equipment. Conventional methods have not been satisfactory in practice.

In these prior arts, the ratio of the suspension base to maltitol used is, as introduced in Japanese Patent Publication No. 7-55898, the amount of maltitol used is 1 unit.
The amount of the suspension base is 0.38 to 0.48 in terms of parts by weight.
It is used in the range of about parts by weight or less, and in the one proposed in Japanese Patent Publication No. 2793283, the coating was carried out with the amount of the suspending base in the range of 1.5 to 3.0 parts by weight. There are also things.

That is, the problem to be solved by the present invention is:
Regarding non-cariogenic sugar-free coating preparations, the coating part has moderate hardness, so it has a light and crisp response when chewed, ensuring an appropriate disintegration rate and protecting effect of the core agent, while cracking Not only has the effect of reducing the generation rate of defective products, such as discomfort in the mouth, and has the effect of high whiteness of the coating layer, but also high protection against the core agent even when the coating layer coverage is low An object of the present invention is to provide a sugar-free coated preparation having an effect and a method for producing the same.

[0016]

[Means for Solving the Problems]

The present inventors have conducted intensive studies in order to solve various problems of the prior art, and as a result, by using a maltitol composition and a specific amount of a suspending base as a main component of a coating layer, the present inventors have found that the present invention is not limited to practical use. The present invention succeeded in producing a sugar-free coated preparation which can be used for the present invention, and succeeded in eliminating the variation in the crystal formation rate by limiting the sugar composition of the maltitol composition.

Means for solving the problems of the present invention are as follows.

First, a sugar-free coating preparation in which the core is coated with a coating layer containing 0.60 to 1.40 parts by weight of a suspending base per 1 part by weight of the maltitol composition. is there. Second, the maltitol composition contains at least 90% by weight of maltitol per solid, and the sum of the contents of maltotriitol and maltotetriitol is 3% by weight or less per solid. A sugar-free coated preparation according to one of the above. Third, the sugar-free coated preparation according to the first or second, wherein the suspension base is one or a mixture of two or more of talc, kaolin, calcium carbonate, calcium sulfate, titanium dioxide or starch.
Fourth, the sugar-free coating preparation according to any one of the first to third aspects, wherein the coating ratio of the coating layer to the core agent is 70% or more. Fifthly, the sugar-free coating preparation according to any one of the first to third aspects, wherein the coating rate of the coating layer with respect to the core agent is 50% or more and less than 70%. Sixth,
Coating layer coverage of core agent is 30% or more and 50%
4. The sugar-free coated preparation according to any one of the first to third aspects, wherein Seventh, in producing a sugar-free coating preparation by coating a core with a coating layer using a coating layer forming solution, a suspension base is used as a coating layer forming solution with respect to 1 part by weight of the maltitol composition. Using a suspension containing 0.60 to 1.40 parts by weight of a sugar-free coated preparation. Eighth, the maltitol composition has 90
7. The method for producing a sugar-free coated preparation according to the seventh aspect, wherein the sugar-free coated preparation contains maltitol in an amount of 3% by weight or less based on solids and contains maltitol in an amount of 3% by weight or more. Ninth, talc,
The method for producing a sugar-free coating preparation according to the seventh or eighth aspect, which is one or a mixture of two or more of kaolin, calcium carbonate, calcium sulfate, titanium dioxide and starch.

Here, the coverage of the coating layer with respect to the core agent is represented by the following equation. Coating layer coverage (%) = (weight of coating layer coated with core agent / weight of coated core agent) × 100

The quality of the maltitol composition used in the present invention is commercially available for foods or pharmaceuticals, and can be used in any form of crystal, crystal-containing powder and liquid. Among various commercial products, the maltitol content in the maltitol composition is 90% by weight per solid.
Or more, preferably 95% by weight or more, more preferably 97% by weight or more.
% Or more can advantageously be used.

However, among the maltitol compositions that can be used in the present invention, maltitol greatly affects the storage stability and strength of the obtained coating layer and is important in controlling the coating layer forming process. It is the sum of the contents of maltotriitol and maltotetriitol contained in the composition, and if the sum is 3% by weight or less based on solids, it can be used more advantageously.

In order to obtain the effects of the present invention, the maltitol composition used in the present invention is used in an amount of 0.71 to 1.67 parts by weight per 1 part by weight of the suspension base. That is, when the amount of the maltitol composition is 1 part by weight, it is required to adjust the ratio of the suspension base to be in a range of 0.60 to 1.40 parts by weight, but a more preferable range is required. Has a suspension base ratio of 1.00 to 1.35 parts by weight with respect to 1 part by weight of the maltitol composition.

The suspension base used in the present invention is required to have a quality that can be used in the food or pharmaceutical fields, such as talc, kaolin, calcium carbonate, and the like.
Calcium sulfate, titanium dioxide, starch and the like can be advantageously used, but those containing calcium carbonate derived from natural products such as eggshell calcium and shell calcium as a main component can also be used. It can also be used as a stinging agent or a spraying agent.

From the experience of the present inventor, the coating layer forming solution used in the practice of the present invention is defined as 1.0 to 1.5 parts by weight of the maltitol composition per 1 part by weight of water. Although the amount of the coating material derived from the coating layer forming solution adhered to the wall surface is small, the coating operation is very easy because a smooth coating surface is obtained, and there is no inconvenience during the operation. The operation is easy even at a ratio of 0.8 to 1.8 parts by weight of the maltitol composition per 1 part by weight of water out of the range.

In practicing the present invention, a material for reinforcing the coating layer is not necessarily required. In addition to the maltitol composition and the suspending base, if necessary, a sweetener, a flavor, a coloring agent, Flavoring agent, disintegrant, film agent,
Polishing agents, reinforcing agents, other sugar alcohol components, for example, monosaccharide sugar alcohols such as erythritol, xylitol, sorbitol, mannitol, disaccharide sugar alcohols such as lactitol, reduced palatinose, reduced starch saccharified products, reduced dextrin, etc. Can be used in a range that does not significantly affect the coating layer forming speed.

As described above, the surface of the core agent is coated or sprayed with the coating layer forming solution, and the temperature at this time is preferably high as long as the components of the core agent do not adversely affect the components of the core agent, such as decomposition or alteration. A temperature of about 80 ° C. is a temperature that is usually easily adopted.

Next, the core material coated or sprayed with the coating layer forming solution is sprayed as it is or, if necessary, a sugar alcohol powder such as maltitol is powdered and dried to promote solidification of the coating material. The coating layer is formed by coating, and the application and drying of the coating layer forming solution may be repeated several to several hundred times as necessary to obtain a sugar-free coating preparation having a coating layer of a desired thickness.

The effect of the present invention can be further enhanced by subjecting the surface of the obtained coating preparation to a coating layer forming operation for finishing and polishing as required.

By carrying out the present invention, a coating surface forming solution, a coating material, a core agent, etc. do not adhere to a coating pan more than necessary during a coating layer forming operation, and a smooth surface can be easily obtained. It can be easily implemented. Therefore, the coating method is economically excellent without wasting the coating layer forming solution.

Further, since the rate of forming the coating layer does not become extremely slow during the operation of forming the coating layer, it is possible to obtain an excellent effect that the process can be easily controlled and the equipment can be automated.

The sugar-free coating preparation obtained by the present invention has a smooth and beautiful white surface, is not too hard, and can secure the strength of the coating layer. In addition, it is possible to realize an excellent effect that the disintegration speed is high, the protective effect of the core agent is high, and there is no unpleasant sensation when put into the mouth and the taste is good.

The sugar-free coating preparation obtained according to the present invention can provide a certain protective effect even if the coating rate of the coating layer is not high. As an index indicating the protective effect of the coating layer, a measurement method in which a preparation is dropped on a glass plate from a point at a height of 70 cm, and the same operation is repeated until the preparation is broken, and the number of times is evaluated as the impact durability. However, the measurement results of the impact durability of the product of the present invention were satisfactory.

The coating rate of the coating layer according to the present invention is 70.
%, The impact durability of the sugar-free coated preparation can be 9 or more. In the case of the sugar-free coating preparation having a coating layer coverage of 50% or more and less than 70% according to the present invention, the impact durability of the sugar-free coating preparation can be 7 or more, but preferably 9 or more. . In the case of the sugar-free coating preparation having a coating layer coverage of 30% or more and less than 50% according to the present invention, the impact resistance of the sugar-free coating preparation can be 5 or more, preferably 7 or more, more preferably 9 or more. The above can also be applied.
