Description

[Detailed description of the invention] 1 consideration” 1 light 1 light I The present invention relates to a method for producing a granular mix.

In the manufacturing method of granular mixed drinks containing sugars such as sucrose, glucose, fructose, etc., in the granulation process conventionally water is used as a binder, or Arabica is used as a binding agent. Aqueous solutions of natural gum-based substances such as gum and guar gum, solutions of sugars such as starch or sugar have been used. However, mixed granules obtained by conventional methods solidify during storage or generate water-insoluble components derived from binders during storage, resulting in a significant decrease in commercial value.
It was a problem.

As a method for preventing solidification of powdered mixed drinks, a method has been devised in which a low DE dextrin is simply mixed. (
However, in this method, in order to prevent solidification, a large amount of dextrin (15 to 60
%), which leads to increased costs, changes in flavor, and powder separation, and also requires a large amount of spooning, which causes trouble when drinking.

In addition, glucose and/or sugar solutions may be used as the sugar solution; however, when protein sugars are dissolved, granulated, and dried, they become extremely susceptible to moisture absorption, and the entire granulated material is likely to solidify due to moisture absorption. There was a drawback.

4 Methods for Solving the Problems An object of the present invention is to solve these problems and provide a method for producing a granular mixed drink at low cost.

As a result of researching the binder used in the mix granulation process, the present inventor sprayed a dextrin aqueous solution with a low DE value (10 or less) during granulation and coated the mix.
It was discovered that by drying, stable granules that are free from solidification during storage can be obtained, leading to the present invention.

The present invention involves mixing sugars such as sucrose, glucose, fructose, powders such as powdered tea extract, coffee powder, and powdered fruit juice, and optionally additives such as acidulants, fragrances, and pigments, and then granulating the mixture. Method 4: A method for producing a granular mixed drink comprising drying, characterized in that the granulation step is carried out while spraying an aqueous dextrin solution with a DE value of 0 or less during part or the entire period of the granulation step.
Regarding this.

Preferably, the modified granulation is carried out by rolling granulation or fluidized bed granulation. Transfer type granulation is (i) rotating container type, (ii)
) vibrating type, (iii) fluidized bed type, (iv) mixing machine type, or (v) a combination thereof.

A dextrin aqueous solution having a DE value of 0 or less is preferably prepared by dissolving dextrin in water so that the total weight ratio of dextrin after granulation is 10% or less. Granulation is carried out by spray coating a dry mix with the dextrin aqueous solution, followed by drying until the water content in the solid content is preferably 3% or less, most preferably 2% or less.

The granular mixed beverage produced according to the present invention is stable as it is prevented from solidifying during storage.

According to this method, the amount of dextrin added with a low DE value exhibits a binding effect in granulation with an extremely small amount (10% or less), and the hygroscopic properties of the resulting granules are extremely low.
Significant benefits were recognized. Therefore, the conventional disadvantages of the influence on flavor caused by adding a large amount of dextrin and the disadvantages of measuring a large amount in spooning granules can be solved.
