Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a method for producing a coated organic acid and organic acid salt preparation to be added as an additive in the fields of food, feed and the like.

<Prior Art> Research on a method for producing a coated organic acid and an organic acid salt preparation has been conventionally performed, and two conventional methods have been developed. In one method, a coating is obtained by suspending an organic acid or an organic acid salt in a dissolved hardened oil, wax, etc., and then spray cooling or solidifying by cooling using a rotating disk (for example, Japanese Patent Publication No. 45). -32217, "Production method of coated organic acid", JP-B-53-31476, "Production method of coated organic acid" and the like). In other methods, a method called flow coating is used to float organic acids and the like from the bottom with wind force, and hardened oil from the top,
Coating is performed by spraying wax or the like, or by a method similar to this.

<Problems to be Solved by the Invention> Coating preparations of organic acids and organic acid salts are used in many fields, and their coating performance is very important. When used in processed meat products, fish paste products, etc., the storage stability of the product can be improved by adjusting the pH of the product. However, if the organic acid and its salt are added directly, the physical properties of the product are impaired. Therefore, by coating with an organic acid or an organic acid salt, it becomes possible to adjust the pH after heating the product. In addition, the organic acid, which is decomposed or oxidized by contact with water, has improved storability by blocking air and water by coating. Furthermore, when the organic acid or the organic acid salt itself has an offensive odor or affects the taste, it can be masked by coating. However, the conventionally developed methods have insufficient coverage and do not exhibit sufficient performance for the above uses.

In addition, since the content of the organic acid and the organic acid salt as the core substance is low, it is necessary to add a large amount of the coating preparation for use, which causes the cost increase.

Furthermore, a large amount of heat must be used and energy must be consumed to melt and spray the coating,
The work including maintenance of the device was complicated.

<Object of the Invention> Therefore, an object of the present invention is to provide a method for producing a coated organic acid and organic acid salt preparation capable of sufficient coating.

Another object of the invention is the need to melt the coating,
Therefore, it is an object of the present invention to provide a method for producing an organic acid or organic acid salt preparation which can avoid the consumption of a large amount of heat and energy, and can easily maintain the equipment used.

Still another object of the present invention is that since the content of the organic acid or the organic acid salt as the core substance is high, a sufficient effect can be obtained by using a small amount of the coating preparation, and thus the cost required can be reduced. It is intended to provide a method for producing an organic acid salt preparation.

<Means for Solving Problems> According to the present invention, a powdery substance of an organic acid or a salt thereof (excluding water-soluble vitamins) is coated with beef tallow, beef tallow hardened oil, fish oil hardened oil, soybean hardened. Melting point 40 ° C. selected from the group consisting of oil, fatty acid monoglyceride, fatty acid diglyceride, propylene glycol fatty acid ester, sucrose fatty acid ester, fatty acid, fatty acid salt and mixtures thereof
The above animal and plant powders are contacted and collided, and the coating agent is adhered and coated on the entire peripheral surface of the powder of the organic acid or salt thereof, and the powder of the organic acid or salt thereof is used as a core substance. There is provided a method for producing a coated organic acid and organic acid salt formulation, which comprises producing a formulation coated with the coating agent.

<Explanation of the Invention> The organic acid which is the core substance usable in the present invention may be a naturally-occurring one or a synthetically-obtained one, and the property thereof may be crystalline or powder at room temperature. The crystalline or powdery organic acid can be used as it is as a raw material, but may be granulated or pre-coated with a water-soluble component or an oily substance. The organic acid that is liquid at room temperature may be impregnated or pre-coated with a water-soluble component, an oily substance, or other components. The organic acid used in the present invention is not particularly limited as long as it is an organic acid excluding water-soluble vitamins. Specifically, for example, sorbic acid, propionic acid, fumaric acid, dehydroacetic acid, benzoic acid, Citric acid, malic acid, succinic acid,
Tartaric acid, oxalic acid, lactic acid, acetic acid, butyric acid, adipic acid, tannic acid, gallic acid, phytic acid, gluconic acid and the like can be preferably mentioned, and they can be used alone or as a mixture when used. As the organic acid salt used in the present invention, sodium salts, calcium salts, potassium salts and other metal salts of the above organic acids obtained naturally or synthetically can be preferably mentioned. Water-soluble components that can be used for granulation / impregnation of organic acids and organic acid salts or preliminary coating include sugars, proteins, amino acids, and inorganic salts. As the oily substance, natural fats and oils, hydrogenated oils, waxes, fatty acid monoglycerides, fatty acid diglycerides, fatty acids and other lipids can be used. Furthermore, as other components, naturally occurring organic / inorganic polymer substances can be used. Two or more of the above organic acids or organic acid salts may be used in combination depending on the application.

Animal and plant powders having a melting point of 40 ° C. or higher which can be used as a coating agent in the present invention include beef tallow, hydrogenated tallow oil, hydrogenated oil of fish oil, hydrogenated soybean oil, fatty acid monoglyceride, fatty acid diglyceride, propylene glycol fatty acid ester, sucrose fatty acid ester, fatty acid. , Fatty acid salts, and mixtures thereof. The powdery substance may be a hydrogenated product. Melting point 40
If the temperature is lower than 0 ° C, a preferable animal or plant powder cannot be obtained, and a good coated preparation cannot be obtained.

As a method of contacting and colliding a powdery material containing an organic acid and an organic acid salt which is a core substance and a powdery animal and plant material having a melting point of 40 ° C. or higher which is a coating material, there are known ball mills, electric mortars and high efficiency. It is possible to use a powder mixing device, a device for bringing powders into contact with each other by convection of high-speed air flow, etc., whereby powdery substances are brought into contact with each other and collide with each other, and collide with an inner wall of the device and an auxiliary tool to uniformly coat. It is desirable to make the contact under mild conditions because there is a risk of crushing the core substance if the contact is performed under excessively intense conditions. In addition, the coating performance can be improved by preliminarily mixing the core substance powder and the coating agent powder when contacting with the above device.

The mixture ratio of the core substance and the coating material (weight of the core substance powder / weight of the coating powder) can be used in the range of 0.1 to 50, but it can be adjusted in relation to the particle size ratio. preferable. When the particle size ratio is large, it is preferable to increase the mixing ratio, and when the particle size ratio is small, the mixing ratio is preferably 4 or less. The coating performance may not be improved simply by decreasing the mixing ratio, but rather the larger the mixing ratio, the better the performance. In addition, even if the mixing ratio is the same, by dividing the coating material powder into two parts, once coating with one of the coating materials, and then adding the remaining coating material powder to cover. The coating performance can be improved.

In any case, coating on the entire peripheral surface of the coating material
Must be attached. This is because the core substance inside is eluted to the outside unless it is coated or adhered to the entire surrounding surface.

<Effects of the Invention> The coated organic acid and organic acid salt preparations produced by the method of the present invention have significantly improved coating performance as compared with conventionally known coating preparations, and are shielded from outside air and moisture and other components. It is possible to prevent contact with, and enhance the use effect in the fields of food and feed. Further, even when the core substance is released to the outside, it is expected to be effective over a long period of time because it is gradually released. Furthermore, according to the method of the present invention, the content of the organic acid and the organic acid salt in the preparation is increased, so that the addition amount of the preparation itself can be reduced, and thus the cost for using the preparation can be reduced. Further, the method for producing the preparation of the present invention can be simplified in terms of energy and workability as compared with the conventional method.

As described above, the coated preparation of the present invention has many unprecedented effects and is extremely useful.

Example 1 Fumaric acid (35 g of average particle size (200 μm) and 15 g of stearic acid monoglyceride together with 10 brass balls, centrifugal rotary mixer (Mekano Mill-MM10, Okada Seiko Co., Ltd.)
And mixed at a rotation speed of 500 rpm for 2 hours. Put 0.5 g of the generated powder and 100 ml of ethanol in an Erlenmeyer flask,
100 times per minute was shaken with a constant temperature shaker, and fumaric acid eluted in ethanol was alkali-titrated and quantified. Table 1 shows the results of the shaking time and the elution rate (the elution rate is the ratio of the fumaric acid eluted to the total amount of fumaric acid in percentage).

As described above, the elution rate of fumaric acid could be significantly reduced by carrying out the operation according to the present invention.
(Untreated ones run in parallel reached an elution rate of 100% immediately after shaking.) Further, a practical application test was conducted using this coated fumaric acid. Frozen ground salmon roe 1500g and seasonings such as salt and sugar 224g, starch 100g, water 1200g Further add fumaric acid 0.2% of fumaric acid pure content and mix well,
Adjusted the fish paste for kamaboko. When steamed boiled fish paste was manufactured, the elasticity of the product was good and the antiseptic effect was that it could be stored at 30 ° C for 5 days. (The fumaric acid-free product could be stored at 30 ° C. for one and a half days.) Comparative Example 1 Fumaric acid was prepared in the same manner as in Example 1 except that the stearic acid monoglyceride of the coating agent was changed to carnauba wax. A coating was produced, shaken, and the amount of fumaric acid eluted was quantified. Table 2 shows the results.

Comparative Example 2 A fumaric acid-coated product was produced in the same manner as in Comparative Example 1 except that the mixing time of the centrifugal rotary mixer was extended to 3 hours, followed by shaking to quantify the amount of fumaric acid eluted. Table 2 shows the results.

From the results of Table 2, the carnauba wax of Comparative Example 1 used as the coating agent and coated with the same mixing time as in Example 1 has a higher elution rate than Example 1 of Table 1 and has poor coating performance. I understand.

On the other hand, in the coated preparation of Comparative Example 2, after the ordered mixture was formed, the frictional heat generated between the particles softened the surface of the wax to form the coating, but the ordered mixture was formed. It was found that the coating time was longer, the elution rate was higher, and the coating performance was inferior, as compared with Example 1 shown in Table 1 in which the direct coating was formed.
