Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a fast-dissolving food formulation. Specifically, the present invention provides a food preparation that imparts wettability to hydrophilic food additives, such as organic acids that are poorly soluble in water, such as adipic acid, benzoic acid, sorbic acid, and fumaric acid, and quickly dissolves in water. Concerning the manufacturing method.

Food additives are defined as compounds classified into more than 10 categories, including seasonings, acidulants, flavoring agents, preservatives, and antioxidants. Some of these are hydrophobic and cannot be dissolved in water. It contains many compounds that are difficult to treat, especially organic acids. For example, adipic acid, benzoic acid, sorbic acid, dehydroacetic acid,
Examples include fumaric acid. Among these, fumaric acid has particularly high acidity, and its sour taste is much stronger than that of citric acid and malic acid, and it is effective when used in small amounts, and is relatively inexpensive. However, since it has almost no hygroscopicity, it is advantageous in terms of handling, but its dissolution rate is low and its solubility is relatively low, and its specific gravity is also small, so when it is added to water, it takes a long time to rise to the surface and dissolve. It has some disadvantages. For this reason, although it has excellent properties, it is now avoided and replaced by other expensive enoic acids and malic acids.

Furthermore, benzoic acid, sorbic acid, dehydroacetic acid, and the like are also useful as preservatives, but the effectiveness of these acid-type preservatives is significantly influenced by their pH, and the lower the pH value, the greater the effect. Therefore, it is desirable to use these in acid form, but they are hydrophobic and unavoidable (p
It is often used in the form of sodium and potassium salts, which have a high H value.

Attempts have been made to improve such hydrophobicity. For example, there are examples in which sucrose fatty acid esters are supported on fumaric acid or sorbic acid. However, this method has the disadvantage that when added to water, the sucrose fatty acid ester does not completely dissolve and becomes cloudy, which significantly impairs the appearance when used in foods.

Fumaric acid granules loaded with maltodextrin are also known, but they have a weak wetting effect and must support a large amount of 5 parts by weight, which is disadvantageous in that they are uneconomical and impair taste.

The present invention overcomes these drawbacks of the prior art, and provides wettability to hydrophobic food additives, especially organic acids, that allows them to dissolve quickly even in small amounts and does not cause cloudiness when added to water. It is characterized by supporting a mixture of polyglycerol fatty acid esters.

That is, the present invention is specified as follows.

(1) A method for producing a fast-dissolving food preparation, which is characterized in that a hydrophobic powdered food additive is mixed and supported with a polyglycerin fatty acid ester.

(2) The method according to (1) above, wherein the food additive is an organic acid.

(3) The method according to (2) above, wherein the organic acid is at least one selected from the group consisting of adipic acid, benzoic acid, sorbic acid, dehydroacetic acid, and hexamaric acid.

(4) Polyglycerin fatty acid ester is an ester of polyglycerin with a degree of polymerization of 3 or more and a saturated or unsaturated fatty acid whose alkyl group has 5 to 17 carbon atoms, and its HLB is in the range of 7 to 18. The method according to (1), (2) or (3) above, wherein the main component is one of the following.

(5) The method according to (1), (2), (3) or (4) above, characterized in that the amount of polyglycerin fatty acid ester supported is in the range of o, oos to 2 weight - based on the hydrophobic powder. Method.

(6) The method according to (1), (2), (3), (4) or (5) above, wherein the hydrophobic powder has a particle size of 20 mesh or less.

The hydrophobic food additives used in the present invention, particularly the organic acids, include those mentioned above, but these are mixed and supported in powder form with the above-mentioned wetting agent in consideration of the use case. In particular, when the powder is treated with a wetting agent while maintaining its granular form without undergoing dissolution treatment, the particle size of the powder must be pulverized to 20 mesh or less.

The polyglycerin fatty acid ester used is one containing the above-mentioned ester as a main component, and specifically, tetraglycerin monolaurate, hexaglycerin monooleate, hexaglycerin monolaurate, decaglycerin monooleate, decaglycerin monostearate,
These include decaglycerin monolaurate.

The supported amount is appropriately selected within the range of 0.005 to 2% by weight based on the hydrophobic powder, and particularly preferably 0.001 to 1% by weight gives preferable results. If it is too small, it will be difficult to mix and support the particles uniformly, and there is a risk that they will float to the surface of the water. On the other hand, if there is too much, it may affect not only the economy but also the flavor. As the supporting method, any method that can coat the surface of the particles of the hydrophobic powder with polyglycerin fatty acid ester can be employed. A suitable example is a dipping method.

In that case, the ester is dissolved in a solvent such as water or ethanol that does not cause deterioration of the ester to prepare an immersion liquid. Hydrophobic powder is immersed in this and thoroughly dried. A method is also adopted in which this immersion liquid is sprayed onto the powder to be uniformly mixed and supported on the particle surface, and the immersion liquid and powder are further mixed,
A method of directly concentrating and heating and drying is also adopted.

In addition to the polyglycerol fatty acid ester described above, other additives such as sodium tripo-IJ phosphate may be added in small amounts to the immersion liquid.

Drying conditions are room temperature to 150°C, preferably 50 to 120°C.
°C is appropriate.

In any of the above supporting methods, the hydrophobic powder is hardly dissolved, and it is possible to form granules that are coated by rolling and hardly changing the particle size of the added particles, but the dissolved portion is not negligible. In this case, it is preferable to use the spray method or the concentration method among the above methods.

The fast-dissolving food preparations obtained in this way, especially those containing organic acids as the main ingredients, have improved solubility to 100%, can lower the pH value, and have a relatively small amount of acidity and storage stability. Enables its use to reach the desired purpose.
