Abstract

PURPOSE:To obtain a colorful improved salt usable like common salt, by blending salt with potassium chloride in a specific blending ratio to give a mixture, mixing the mixture with an edible dyestuff uniformly. CONSTITUTION:A mixture consisting of 30-90wt% salt and 10-70wt% potassium chloride is previously stirred, and this composition is blended with 2- 3wt% aqueous solution of edible dyestuff or mixture of 2-3wt% aqueous solution of edible dyestuff and 1-3wt% calcium secondary phosphate. The blend is stirred mildly until it becomes a proper water content while being heated in 60- 80 deg.C thermal atmosphere. Though the edible dyestuff can be selected arbitrarily, red 102, red 106, yellow 4, blue 1, etc. are suitable.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a modified salt with a low sodium content that can be used in the same way as ordinary common salt and is easy to identify.

In recent years, there has been increasing interest in the various harmful effects of excessive salt intake, and the benefits of low-salt diets have been advocated.

By the way, the harmful effect of table salt is that the sodium that makes up sodium chloride disrupts the sodium-potassium balance in the body.
The main cause is said to be when it affects internal division functions. Traditionally, to avoid excessive intake of sodium,
Salt substitutes are available that are made by mixing up to 1/3 potassium chloride with sodium chloride, but the appearance is very similar to common salt, making it difficult to identify, and the quality of the composition is inconsistent, making it unsuitable for practical use. There were drawbacks.

In particular, modified salt used for salt taste adjustment is usually in a very small amount of several q to several 2, and even in such amounts, the composition must be kept sufficiently uniform. ◇Conventional products:
Even though the composition is simply mixed and stirred with common salt and additives, and the composition remains uniform during preparation, packaging,
There is a drawback that the uniformity of the composition cannot be maintained due to vibrations during distribution stages such as packaging and transportation, or during use.

The present inventor made the dining table colorful by coloring the composition mixed with potassium chloride to an identifiable degree,
It is a modified salt that improves the appetite and is convenient for the user, such as making it easy to know how much to use, and that each component is uniformly distributed in an appropriate particle size and can be used in the same way as regular table salt. In order to provide quality salt, as a result of repeated research, we discovered that extremely stable and high quality colored modified salt can be obtained by heating and gently stirring in the presence of a small amount of water.

In addition, the present inventor has modified the modified salt from a simple salt flavoring agent by adding dibasic calcium phosphate to -1-) IJ
They focused on the fact that it can be used as a nutritionally superior seasoning that is rich in calcium and has a low content of calcium, and succeeded in obtaining a stable composition.

That is, the present invention provides a modified salt containing common salt and potassium chloride as main components and uniformly coloring this homogeneous composition.
To a mixture consisting of 10 to 70% by weight of potassium chloride, food coloring was dissolved in 2 to 3% of the total weight of water and added, and in a thermal atmosphere at 60 to 80°C.
．． It is characterized by evaporating water and uniformly coloring the product while gently stirring with a rotary blade rotating at 8 to 2 J, P, M. By mixing and adding 1 to 3% by weight of the dibasic calcium phosphate to the aqueous food coloring solution, the dibasic calcium phosphate is evenly and stably mixed.

The common salt used in the present invention is a common commercially available product. The mixing ratio of potassium chloride to common salt is based on taste and medical effects, and the potassium chloride in the mixture is M% by weight.
Preferably 20-40%, at least 10%
70% or less. Although the addition of water in this manufacturing process is essential, the amount should be appropriately adjusted depending on the water content of the salt, and it is important that the amount is such that only the surface of the mixed composition is uniformly dissolved. That is, this water is
Dissolves the dye and distributes it uniformly in the mixture, and
In the process of dissolving the surface of salt and potassium chloride and evaporating it to dryness, it works to stably fix the pigment.
2-3% by weight of the total mixture is suitable. Coloring can be selected from food coloring! I can do it, but Red No. 102 and Red No. 106
No. 4, Yellow No. 4, Blue No. 1, etc. are suitable, and can be added as an aqueous solution of any concentration. The dibasic calcium phosphate is added to foods as a reinforcing agent, and the appropriate amount is 1 to 3% by weight of the total. In addition, in addition to the above, calcium carbonate, magnesium carbonate, citric acid, succinic acid, d-tartaric acid, dl-
Tartaric acid, dl-apple wrinkle, hexamaric acid, etc. may be appropriately selected and added.

In the present invention, it is desirable to use containers with rotating speed mechanisms that rotate independently.

To explain this container equipped with a heating mechanism equipped with a stirring device, the υζ in the cylindrical container with a flat bottom is 0°8 to 2.0 mm, rotary blades that rotate gently at P, M, and 25 to 25 OR.
, P, M, are equipped with stirring blades that rotate. The rotary blade is attached to the rotating shaft with an inclination so that the powdery material is collected in the center of the container, and the stirring blade stirs the powdery material scraped together by the rotary blade horizontally and in the vertical direction.

Due to the mutual action of the rotary blades and the stirring blades, the mixing effect is higher than the flow rate of the powder particles, and therefore, crushing of the powder particles can be prevented to a minimum.

The heating mechanism is formed by a jacket attached to the bottom of the container and a duct attached to the F section of the container, and hot water or steam is sent into the jacket, and hot air is sent from the duct.

The purpose of sending hot air is to stir the air inside the container and make the thermal atmosphere inside the container uniform.

First, common salt and potassium chloride are thoroughly mixed in advance, and then an aqueous dye solution, or an aqueous dye solution and an additive such as dibasic calcium phosphate are added. Heat the above mixture at 60-80°C.
The water is evaporated in a thermal atmosphere of about 80° C., preferably with stirring. This stirring is done by using a rotating blade for stirring.
0.8-2. It is appropriate to rotate with OR, P, and M. However, it is appropriate to adjust it depending on the shape and content of the blades, and stirring with a high-speed stirring blade is often performed intermittently, so that the additives do not become salty. It is important to give time for the growth to adhere to the surface. The stirring time requires approximately several tens of minutes until the water in the mixture evaporates and the mixture reaches a state similar to that of ordinary common salt. During this process, the additives are uniformly attached to the salt and potassium chloride, and the pigment is completely fixed. The resulting composition has extremely stable properties, with additives stably attached to the surface of the salt with an appropriate particle size distribution, and the entire composition being uniformly colored.

Next, the present invention will be explained in detail with reference to Examples.

Example (1) 780 Kq of common salt and 2 o Kg of potassium chloride were added to the rotor blades 5 to 7R, P, M, (peripheral speed of the outer periphery 35 to 55 m/K11ls, peripheral speed of the center part 20 to 30 m) in the above-mentioned container.
/genus i, inner circumferential speed 6 to 10 m/i), stirring blade 150
After mixing and stirring at R, P, and M for 5 minutes, 15 KQ of dibasic calcium phosphate, 15 KQ of calcium carbonate, and 5 Kg of magnesium carbonate were added to 30 Kq of water, and the mixture was thoroughly stirred and placed in the above container. Add to.

At the same time as adding the additive, steam is introduced into the jacket, and
The container was heated with hot air heated to 80° C., and the mixture was mixed and stirred at the same rotational speed for 10 minutes. After that, the rotation of the rotor blade is 0.8R', P,,M.

(Peripheral speed at outer circumference 5-8m/m, circumferential speed at center 3.4m/m)
The inner circumferential speed was reduced to 1 m/5 in), and the stirring blade was rotated at 5 OR, P, M, and intermittent stirring was repeated every 3 minutes. After 40 minutes, the operation was stopped and one product was taken out.

Example (2) In a container equipped with a heating mechanism equipped with a stirring device consisting of the above-mentioned slow rotary blade and fast stirring blade, salt 785 and 9.
Add 200 Kq of potassium chloride and install rotor blades 5-7R, P.
,,M,, Stirring blade 150R,P.

M, after stirring and mixing for 5 minutes, add 20 parts of water, 9 parts, and 10 parts of red.
Add 5 g of No. 2 calcium phosphate, 15 parts of dibasic calcium phosphate, and 9 parts to a mixture that has been sufficiently stirred in advance. At the same time as the addition, the heating mechanism is activated to introduce steam into the jacket, blow in hot air heated to 80°C, and stir and mix under the same conditions as above for 7 minutes. Next, the rotation of the stirring blade is stopped, and only the rotor blade is exposed to the IR.
, P, M, (peripheral speed of outer circumference 7, 2 m/yiin,
Circumferential speed in the center: 4.3 m/11 Inside circumferential speed: 1-3 m/m
) and stir thoroughly until excess water evaporates and the mixture takes on a salt-like appearance. During this time, it takes about 40 minutes.

The composition thus obtained was a uniformly colored material with appropriate particle size, and as a result of microscopic observation, it was found that the additive was uniformly adhered to the salt surface.

In addition, about 70% by volume was placed in a PIICT (polyethylene terephthalate) container, the amplitude was 50 mm, the frequency was 300 times/
When the mixture was shaken for 10 minutes, no separation of the additive was observed. Also, in this group, the contents are PET
It was placed in a container and left at room temperature for 6 months, but no discoloration was observed.
