Description

Manufacturing method of functional sun salts {Manufacturing method of functional sun-dried salt}

The present invention relates to a method for producing a functional sun salt, and more particularly, to a method for producing a functional sun salt in which nutrient substances are reinforced by adsorbing functional substances beneficial to the human body on sun salt.

In general, salt (NaCl) is a representative salty substance, and sodium is an important cation in human extracellular fluid, which regulates osmotic pressure of body fluids, is involved in acid-base equilibrium, and stimulates not only neurostimulatory transporters but also gastric acid. It helps to produce digestive fluids, is involved in enzymatic activity, and produces the purest salty taste, so it is widely used as a seasoning for flavoring foods and improving shelf life.

As a method of obtaining salt, a method of concentrating seawater is mainly used, and it is classified into a purified salt obtained by firstly refining the natural salt and sun salt obtained by injecting seawater into a salted salt facility and evaporating water by sunlight and wind power.

Natural salts have a salinity of 80-88% or more and low salinity, but they contain impurities. Especially, natural salts obtained in contaminated areas contain harmful substances such as heavy metals. The purified salt is produced by removing only pure salt components purified by removing ions and heavy metals through seawater through an ion exchange membrane, making salt crystals using high pressure steam in a vacuum evaporation tube, and then dehydrating them in a centrifuge. These refined salts have a salinity of 95-99% or more, and there is a problem that minerals beneficial to the human body are also removed along with harmful components.

Since salt causes high blood pressure and the development of various adult diseases when consumed excessively, alkali salts of organic acids having a salty salt-like taste, for example, disodium maleate, diamonium malonate, diamonium sebacate, sodium gluconate Organic salts, such as and the like, are used as a saline substitute for patients with kidney disease, liver disease, high blood pressure, etc., or may be used for the preparation of unsalted soy sauce.

In addition, as a method of reducing the intake of sodium chloride salt, there has been suggested a method of mixing potassium chloride, which is an alkali metal salt of the same group on the atomic periodic table, or converting it into potassium chloride in its entirety. Is not preferred to remain.

As described above, natural salts contain harmful components to the human body, and refined salts contain little components such as minerals beneficial to the human body, and organic salts are not economical because they are expensive to manufacture.

Therefore, recently, a method of replenishing nutrients deficient in salt by mixing useful salts contained in plants such as onions with refined salts has been proposed, but it is beneficial to the human body such as minerals in that it uses purified salts obtained through seawater. It is not contained satisfactorily. In addition, while extracting the components of the plants by adding water to the boil method, there is a problem in that only by adding water to boil the effective ingredients contained in the plants are not sufficiently used.

The present invention has been made to improve the above problems, by providing a functional salt to the surface of the natural salts by adsorbing the functional substances beneficial to the human body on the surface while using the usefulness of the natural salts as it is to enhance the nutritional substances lacking in the natural salts Its purpose is to.

Method for producing a functional sun salt of the present invention for achieving the above object is a pre-treatment step of removing the water and liver water of the collected sun salt; A selection step of selecting the sun salt having a predetermined size among the sun salts; A ripening step of aging by adding water to the natural salt selected in the selection step; A post-treatment step of adding a functional material in a powder form to the sun salt aged in the aging step; And a drying step of drying the sun salt so that the functional material can be adsorbed onto the sun salt surface.

The sorting step includes the steps of a) removing the large salts larger than 3 mesh particle size of the natural salts passed through the pretreatment step, b) drying by irradiating far infrared rays to the natural salts from which the salts have been removed, and c) 6 of the natural salts. Removing debris smaller than the mesh particle size.

The functional material is pulverized by pulverizing any one or more selected from turmeric, green tea, Cheonggukjang.

The functional material is characterized in that it further comprises a skate powder.

As described above, according to the present invention, the functional substances beneficial to the human body are adsorbed on the surface of the natural salt to enhance the nutritional substance deficient in the natural salt while using the usefulness of the natural salt as it is. Therefore, the active ingredient of the functional substances are added to be useful for health, and less salty to improve the palatability.

In addition, it is expected that the natural salt can be coated in various colors by the intrinsic pigments of the functional material, thereby increasing the functionality.

1 is a block diagram of a method for producing a functional sun salt according to an embodiment of the present invention.

Hereinafter, a method for preparing a functional sun salt according to a preferred embodiment of the present invention will be described in detail. With reference to the accompanying Figure 1 will be described the present invention by manufacturing process.

1. Pretreatment of Sea Salt

First, a pretreatment step is performed to remove water and liver water contained in the collected sun salt.

The pretreatment step includes, for example, a washing process of washing the sun salt to remove foreign substances, and a dehydration process of dehydrating the washed sun salt.

In order to remove various foreign substances or impurities from the natural salt obtained by evaporating the seawater of the uncontaminated sea water by the solar salt method, the natural salt is put into a container and stirred with water sprayed to wash it once or twice. This washing process removes foreign matters such as suspended matter, soil, straw, and sand contained in the sun salt. In addition, some of the water is removed through the washing process. Next, the water and water remaining in the washed natural salt are removed. The washed natural salt is put in a dehydrator and rotated to remove moisture.

On the other hand, the pretreatment step may further include a step of drying the sun salt at a high temperature after the dehydration process. This is to remove the moisture and foreign substances remaining in the sun salt. The dehydrated sun salt is placed in a heating apparatus and dried by heating until it is completely dried at 200 to 300 ° C. Through the drying process, natural minerals can be preserved while burning foreign substances remaining in the natural salt, and harmful gases such as chloride gas can be removed.

2. Screening of Sea Salt

After the pretreatment step is performed a screening step of selecting the sun salt having a certain size of the sun salt. Through this screening step, the sun salt, which preferably has a size of 3 to 6 mesh particles, is separated. If it exceeds 3 mesh, the water content inside the natural salt particles is high, and there is a fear of deterioration due to moisture after adsorption of a functional substance to be described later, and the crystal surface is not uniform, so that uniform adsorption is difficult. In case of less than 6 mesh, the moisture content inside the sun salt particles is low and the crystal surface area is small, so that the adsorption of the functional material is difficult.

The sorting can be done in a vibration filter. Two standard bodies are installed inside the vibration filter. 3mesh standard body is installed at the top, and 6mesh standard body is installed at the bottom. Through the inlet of the vibration filter, the natural salt may be added to separate particles collected between the two standard bodies to screen particles having a size of 3 to 6 mesh particles.

For example, the screening step may include removing a large salt larger than 3 mesh particle sizes of the natural salts that have been subjected to a pretreatment step, radiating and drying far infrared rays to the natural salts from which the salts have been removed, and washing the salts smaller than the 6 mesh particle sizes of the natural salts. It may be made to remove the step.

After removing the salt by using the 3 mesh standard, dry it using a ceramic dryer that can emit far-infrared rays. The moisture of the sun salt itself causes the hydrophilic crystals to entangle with each other, making it easy to separate the heavy salt and the three salts through the drying process. Natural salts dried using a ceramic dryer are used to remove fine salts smaller than 6 mesh particle size using 6 mesh standard to select particles of 3 to 6 mesh particle size. In the above, the salt refers to the sun salt having a size larger than 3 mesh particle size, the heavy salt means a sun salt having a size of 3 to 6 mesh particle size, and the salt salt refers to a sun salt having a size of less than 6 mesh particle size. Therefore, only the heavy salt is selected through the screening step.

3. Ripening step

Natural salts selected in the selection step, ie heavy salts of 3 to 6 mesh particle size, are aged. After the aging step is added water to the selected natural salts and left for 8 to 24 hours at room temperature (20 to 25 ℃). For example, 5 to 20 parts by weight is applied to 100 parts by weight of sun salt. The aging process restores the state of moisture before drying in the screening step.

4. Post-Step

A post-addition step of adding a functional material in powder form to the sun salt aged in the aging step is performed. Through the post-stage step, natural salts can be adsorbed to the functional material useful to the human body to increase the functionality of the natural salts.

Turmeric may be used as an example of the functional material.

Turmeric is a perennial herb of the Zingiberaceae family, and the root stem of rhizome (root) in Chinese medicine is used as a hemostatic drug due to its mild nature. The herbaceous tree is said to remove bad blood and to treat blood pressure, bleeding, cracks.

Curcumin contains about 100 kinds of essential oils (curcumin), volatile essential oils such as umerone, cineol, α-curcumen and curcumol, and abundant minerals. Curcumin is a chemical component of 1,7-bis (4-hydroxy-3 methoxyphenyl) -1,6-heptadiene-3,5-dione, insoluble in water, and has an orange-yellow crystalline powder. Physiological activities such as antioxidant and anti-inflammatory activity of curcumin have been found (FoodChem, Toxicol 2002 Aug: 40 (8): 1091-7, Surh YJ.). Anti-cancer activity inhibited cancer cell proliferation (The J. Laborstory & Clinical medicine 1997: 576-583, Hanif, R. et al.) And preventive effects on skin, colon and oral cancer in rats (Carcinogenesis, 2000, 21 (2). ): 331-335, Chayng, SE et al). In addition, free radical scavenging and hepatoprotective effects have been shown (Planta Med 2001 Dec: 67 (9): 876-7, Song EK et al.). In addition, the prophylactic and cholesterol inhibitory activity of Alzheimer's disease (Indian J Physiol Pharmacol 1992 Oct; 36 (4): 275-3, Soni KB, Kuttan R.) has also been recently discovered.

Turmeric is used in powder form. For this purpose, turmeric can be obtained by drying and pulverizing using one selected from freeze drying, vacuum drying, low temperature vacuum drying and hot air drying. Preferably freeze drying (FD) is used. Lyophilization utilizes a conventional lyophilization method which is applied in preparing foods. For example, it is possible to rapidly freeze the turmeric for 12 to 13 hours at a temperature below -40 ° C, and then dry it for about 20 hours by applying low-temperature heat to 30 to 40 ° C stepwise in a freeze dryer having a vacuum degree of 0.5torr or less. . When the turmeric is lyophilized, a high quality turmeric powder can be obtained. Since moisture is removed by sublimation in the frozen state, the dried product has a light porous structure, maintains its original shape and size, and has a low loss of volatile fragrance components. In addition, since it is processed at low temperature, there is no liquid water, and in the sublimation part, it is rapidly transferred from the fully hydrated state to the almost dehydrated state, so transfer of soluble components, non-enzymatic browning, protein denaturation, etc. This rarely happens.

In addition to the turmeric described above, green tea, Cheonggukjang may be used as a functional material. Of course, the functional materials may be used alone or in combination of two or more.

Cheonggukjang is one of the traditional fermented soy sauce, soybean paste, and red pepper paste. It contains more soy protein and fat than soybean paste and has a high digestion absorption rate. Intestinal effect of Cheongguk bacteria, prevention of constipation of fiber, extracorporeal release of carcinogens and cholesterol, anticoagulant effect of alcohol absorption of viscous substance, enhancement of saponin and blood circulation and lactic acid degrading effect, lecithin brain aging and dementia It is also known to have effects such as prevention of hypertension and atherosclerosis.

Cheonggukjang is lyophilized, vacuum dried, low temperature vacuum dried and hot air dried, preferably lyophilized and ground to use in powder form.

Green Tea is Thea sinensis L. ) leaves, green tea is not only widely used as drinking tea, it is well known that many studies on the efficacy has already been revealed. Green tea contains active ingredients such as catechin, beta-carotene, various vitamins, and fiber, which are useful for the human body, and these ingredients are known to help anti-aging, anticancer, lower cholesterol, suppress high blood pressure, and remove environmental hormones.

Green tea is pulverized and dried using a conventional steaming process.

On the other hand, in addition to the turmeric, Cheonggukjang, green tea described above as a functional material may further comprise a skate powder. Skate powder may be used alone or mixed with turmeric, Cheonggukjang, green tea.

Skate powder is obtained by lyophilizing skates. Skate ray is a cartilage and benthonic fish belonging to Ray family, and has a particularly high commercial value in Korea, and is known for its mussels eaten with makgeolli. The herbaceous cortex was called sunfish, and the shape resembles a lotus leaf. In the asset language, it is called smelt, and the generic name is called snail (洪 魚), and it introduces the taste of snail in Naju as a form, ecology and food.

These skates are reports of high protein alkaline nutritional foods. Skates are effective for arthritis, rheumatism, and bronchial, and because it removes waste, cleanse the intestines, inhibit gastritis, detoxify alcohol poison, and sticky mucus is known as a stamina food. 100g of skate contains about 19g of protein, compared to 70g of adult daily intake, and is a relatively high protein food with 0.5% fat content. The flesh and liver of skates contain 75% polyunsaturated fatty acids, which contain more than 35% EPA, DHA and free amino acids (TAURINE). EPA and DHA inhibit the induction of coronary artery disease and thrombosis. DHA is known as a major component of retina and brain tissue. Free amino acid (TAURINE) is effective in preventing stroke, vascular disease and heart failure.

In particular, skates contain a lot of urea and urea precursors in the body to control osmotic pressure in deep seas. So, when you mature your skates, ammonia is generated, which stimulates the nose and gives off a tangy taste. In addition to ammonia, substances with various physiological functions are generated. Smashed Skates (Matured Skates) are strong alkaline foods that convert acid into alkaline constitutions and are known as good foods for postpartum cooking to prevent osteoporosis, and have been transmitted as foods that are good for skin recovery, blemishes, freckles, black mushrooms and skin care. .

Therefore, in the present invention, although the freshly caught fresh fish can be used in the sea, it is preferable to use the freshly ripened fish for a certain period of time. In this case, it can be used after aging for 3 to 9 days at about 15 ℃ to 25 ℃.

The above-mentioned functional material is used in powder form, i.e. in powder form of 100 to 200 mesh particle size. The functional material is added to 3 to 20 parts by weight based on 100 parts by weight of the natural salt and then mixed to mix uniformly.

5. Drying Step

Drying the sun salt so that the functional material can be adsorbed on the surface of the sun salt. Preferably, it is possible to prevent denaturation of the adsorbed functional material by drying for 8 to 20 hours at a low temperature of less than 18 ℃, such as 10 to 18 ℃. Preferred moisture content is 5 to 10% by weight. Through this drying step, the functional material can be effectively adsorbed on the surface of the sun salt.

Hereinafter, the present invention will be described through examples. However, the following examples are intended to illustrate the present invention in detail, and the scope of the present invention is not limited to the following examples.

(Example 1)

Sun salt collected in Suncheon Bay was placed in a container and stirred with water to be sprayed, washed twice twice, and dehydrated using a dehydrator. After dehydration, natural salts of 3 ~ 6 mesh particle size were selected and aged for 10 hours at 20 ° C by adding water. 5 parts by weight of lyophilized and ground turmeric powder was added to 100 parts by weight of sun salt, and then uniformly mixed, and dried to about 8% by weight of moisture at a low temperature of 18 ° C. to prepare a functional sun salt.

(Example 2)

Functional sun salt was prepared in the same manner as in Example 1, but Chungkookjang powder was applied instead of turmeric powder.

Example 3

Functional sun salt was prepared in the same manner as in Example 1, but green tea powder was applied instead of turmeric powder.

(Example 4)

Functional sun salt was prepared in the same manner as in Example 1, but skate oil powder was used instead of turmeric powder.

(Comparative Example)

Sun salt collected in Suncheon Bay was placed in a container and stirred with water to be sprayed, washed twice twice, and dehydrated using a dehydrator. After dehydration, natural salts of 3 ~ 6 mesh particle size were selected and dried to about 8% by weight of water.

<Sensory test>

Hereinafter, a sensory test was performed on sun salt of Examples and Comparative Examples of the present invention. A total of 15 trained inspectors from 20 to 50 men and women were selected by panel to evaluate the appearance, aroma, taste, and overall preference of sun salt by the following 9-point scale method. The results were analyzed by Duncan's multiple range test after ANOVA test using SAS (Statistical Analysis System) and by least significant difference test at 5% level. The above sensory test results are shown in Table 1 below.

division Exterior incense flavor Overall likelihood Example 1 8.73 8.41 8.59 8.51 Example 2 8.16 8.27 8.30 8.25 Example 3 8.78 8.65 8.42 8.60 Example 4 8.20 8.21 8.38 8.27 Comparative Example 1 6.42 5.29 6.73 6.14

Looking at the results of Table 1, it can be seen that the examples in the appearance, the smell is much higher than the comparative example. In particular, the appearance of Example 1 and Example 3 was high, which is due to the effect of the natural salt of Example 1 is yellow color of turmeric, and the natural salt of Example 3 is coated with green color of green tea .

In addition, in the case of the comparative example in the taste is a salty taste is low, whereas in the case of the examples, the salty taste was less, the score was higher. This confirmed that the present invention can greatly improve the preference of sun salt. Therefore, the natural salt prepared by the present invention is less salty than conventional salt, and is expected to be useful for health by adding effective ingredients of functional substances.

In the above, the present invention has been described with reference to one embodiment, which is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.
