Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a readily soluble granular food product, in which a powdered food product is mixed with an organic acid and a carbonate, and then granulated by a dry granulation method.

This invention provides easily soluble granules that prevent the generation of dust when handling powdered foods, improve fluidity, and at the same time do not cause so-called "stickiness" when dissolved or dispersed in water, hot water, etc. The purpose is to provide food in a variety of forms.

Powdered foods have poor fluidity, tend to generate dust, and sometimes pose a risk of dust explosion. Also, water,
When dissolved or dispersed in hot water or the like, so-called lumps occur, making it difficult to dissolve and disperse uniformly.

In general, bulk specific gravity of powder, fluidity, dust generation,
In order to improve solubility, dispersibility, etc., granules are being formed.

However, depending on the type of powdered food, granules may sometimes dissolve and disperse poorly. In particular, when granules are made using a dry granulation method in which granulation is applied under pressure, the adhesion between the powder particles becomes strong, so the granules often become difficult to dissolve or disperse even when added to water, hot water, etc. . When such granules are added to water, hot water, etc., they do not dissolve or disperse uniformly, and coarse particles remain, which is unpleasant.

The inventor of this invention researched a method for improving the dissolution and dispersibility of granular foods made into granules using a dry granulation method. It was discovered that granules can be easily dissolved and dispersed, and this invention was completed.

That is, the granular food obtained by the present invention contains organic acids and carbonates in each particle of the granules, and when added to a liquid such as water or hot water,
Both dissolve and react to generate carbon dioxide gas inside the granules, and the granules collapse due to the gas pressure and the powder particles are dispersed, resulting in better dissolution and dispersion, and this does not occur as is.

The powdered food of this invention is in powder form,
Refers to foods that tend to form lumps when dissolved or dispersed by adding liquids such as water or hot water. Such foods include, for example, cocoa, powdered green tea, powdered milk, instant soups, instant desserts, milkshake base,
There are ice cream mix powders, powdered seasonings, etc. It is also possible to process and add raw materials such as additives used in these powdered foods by the method of the present invention.

This invention is carried out by mixing an organic acid and a carbonate with a powdered food and then forming the mixture into granules using a dry granulation method.

The organic acids and carbonates used here should be in the form of powder or granules since liquid ones will react during treatment. That is, citric acid, malic acid, tartaric acid, fumaric acid, etc. are used as organic acids,
Potassium salts, sodium salts, ammonium salts, etc. are used as carbonates. Note that the carbonates of the present invention include bicarbonates. In addition, the amount of organic acids and carbonates for powdered foods is determined depending on the type and nature of the target powdered food, the state when granulated, the type and state of the organic acids and carbonates to be mixed, but the total amount of these 0.1 of powdered food
% or more is effective, and it is usually desirable to use 0.5 to 5%. The ratio of organic acids and carbonates is determined depending on the target food, taking into account the taste and properties, but it is desirable that the ratio be acidic when added to water, hot water, etc., and dissolved or dispersed. Keep the pH below 6.8.

In order to prevent reactions during the production and storage of the granular food of the present invention, at least one type of organic acid or carbonate is coated with a moisture-proof coating material such as oil or fat or an emulsifier before the powder is prepared. Preferably mixed with food.

To make powdered food into granules using dry granulation method,
This is carried out by methods such as granulation using oil as a binder or compression granulation of powder.

That is, fats and oils are added to a powdered food containing organic acids and carbonates, and the mixture is granulated using an extrusion granulator such as a screw type or screen type. Powdered food to which organic acids and carbonates have been added is compressed and granulated using a tabletting machine or briquetting machine, and then granulated as is or, if necessary, by coarsely crushing it with a granulating mill, etc. do. In particular, granules that have been granulated using a method such as a compacting machine, etc., where they are compressed under a pressure of several tons/cm ² without using any binder, are made into plate-like materials, and are roughly crushed using a granulating mill, etc. When the method of the present invention is carried out, excellent dissolution and dispersibility can be obtained. The granules thus obtained are sieved if necessary to make the particle size uniform.

Next, the present invention will be explained by examples.

Example 1 17 parts of sweet corn powder (parts by weight, the same applies hereinafter), 14 parts of vegetable corn syrup, 11 parts of whole milk powder
11 parts potato starch, 4 parts butter, 4 parts lard,
6 parts salt, 3 parts monosodium glutamate, 25 parts sugar
parts, 1.5 parts sodium bicarbonate, 1 part sodium carbonate
part, fumaric acid 1 part, succinic acid 1 part, malic acid
After mixing 0.5 part at 35°C, granulation was performed using a screw-type extrusion granulation device to obtain a granular soup. This substance was easily dissolved and dispersed by simply pouring boiling water into potage soup.

Example 2 17.5 parts of cocoa powder (fat content 22%), 0.4 parts of sodium bicarbonate, 0.2 parts of citric acid, 1.7 parts of vegetable hydrogenated oil, and 0.2 parts of emulsifier were mixed at 36°C and then mixed in a screen extrusion granulation device. It was extruded and granulated and sieved to obtain granular cocoa. Next, 65 parts of granulated sugar and 15 parts of instant cream powder were added to this granular cocoa and mixed uniformly to obtain easily soluble milk cocoa. When hot water was poured into this product, it was easily dissolved and dispersed without stirring, forming milk cocoa.

Example 3 1.6 parts of sodium bicarbonate, 1.0 part of citric acid, and 0.8 parts of cocoa mass were mixed at about 32°C, then cooled to 20°C, solidified, and ground to obtain a mixture of sodium bicarbonate and citric acid coated with cocoa mass. Obtained. Next, 96.6 parts of cocoa powder was added to this mixture, mixed, and compression molded using a compacting machine.
The obtained plate-like material was crushed using a granulating mill and sieved to obtain granular cocoa. When hot water was poured into this product, it was easily dissolved and dispersed, and sugar was added to make it drinkable.

Example 4 21 parts cocoa powder, 33 parts whole milk powder, 42 parts powdered sugar
1.0 parts of citric acid, 22 parts of sodium bicarbonate, 0.5 parts of emulsifier, 0.3 parts of fragrance, 0.6 parts of salt, and 0.4 parts of thickening agent. and sieved to obtain a granular milk cocoa preparation. When hot water was poured into this mixture, it was easily dissolved and dispersed without stirring to obtain milk cocoa.
