Description

Manufacturing method of salt using kelp {Manufacturing method of salt using sea tangle}

The present invention relates to a method of preparing salt using kelp, and more particularly, to remove various foreign substances or heavy metals contained in sun salt and to contain active ingredients of plants beneficial to the human body. It relates to a method for producing 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 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 to 99% or more, and there is a problem in that minerals beneficial to the human body are also removed along with harmful components.

Since these salts cause 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 glucose Organic salts such as Nate may be used as a saline substitute for patients with kidney disease, liver disease, high blood pressure, or the like, or may be used for preparing 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 ingredients contained in plants such as green tea and onion with refined salts has been proposed. The beneficial ingredients are not satisfactorily contained. 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.

On the other hand, seaweeds, including kelp, are rich in vitamins and minerals, which are said to be a treasure trove of vitamins and minerals. Vitamins include A, B1, B2, C and niacin. Minerals include phosphorus, magnesium, sodium, potassium, silicon, iron, manganese, zinc, copper, aluminum, arsenic, selenium, iodine, cobalt and fluorine. Chromium, tin, nickel and the like are contained in seaweeds.

In particular, kelp is known to contain a lot of protein, fat, sugar, calcium, iron, iodine and vitamin C, minerals about 20-24%.

Most of these minerals are used as an ingredient in enzymes that are involved in the body's metabolism. So no matter how small the amount, if it is not available, it will not produce enzymes, and without it, metabolism will stop there. To stay healthy, you must consume all the minerals you need.

The present invention was created to improve the above problems, while using the mineral contained in the natural salt itself, while effectively extracting various active ingredients of kelp, and containing a high concentration of salt using the kelp improved in human health and preference The purpose is to provide a manufacturing method.

It is another object of the present invention to provide a method for preparing salt using kelp that is effective in addition to edible as well as cosmetics such as bathing agents and face washes by adding an active ingredient of a plant having excellent antibacterial and anti-oxidant activity with kelp. There is a purpose.

Method for producing a salt using a kelp of another embodiment of the present invention for achieving the above object is a washing step of washing the sun salt to remove foreign substances from the collected sun salt; Dehydration step of dehydration to remove water and liver water of the natural salt washed in the washing step; A drying step of heating and drying to remove moisture and foreign substances remaining in the dehydrated sun salt in the dehydration step; Kelp liquid extraction step of extracting kelp liquid by heating the kelp into a water bath; A primary heating step of dissolving the sun salt by mixing and heating the sun salt dried in the drying step with the kelp solution extracted in the extraction step; And a secondary heating step of heating to crystallize the salt after the primary heating step.

In the first heating step, the pomegranate fruit shell extract extracted by heating the pomegranate fruit shell is characterized by further mixing.

The first heating step is characterized by further mixing the herbal extract.

As described above, according to the method for preparing salt using kelp of the present invention, the kelp is heated by boiling water to effectively extract the active ingredient of kelp and absorbed by sun salt, so that not only minerals contained in sun salt itself but also various minerals contained in kelp are effective. By making the most of the ingredients, it provides beneficial salts to the human body.

In addition, the salinity is lowered and the kelp is contained in a high concentration, which improves the taste of the salt itself, thereby improving the taste and eliminating the side effects of artificial seasonings. You can.

In addition, the extract of pomegranate or herb is added, so it has excellent antibacterial and anti-oxidant effect. When used as a cleaning or bathing agent, anti-inflammatory, soothing and stress relief are expected without causing skin irritation. Provide this possible salt.

Hereinafter, a method of preparing salt using kelp 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. Washing of Sea Salt

First, in the washing step of the sun salt, in order to remove various foreign substances or impurities from the sun salt obtained by evaporating the seawater of the sea which is not contaminated by the sun salt method, the sun salt is put in a container and stirred with water sprayed for one to two times. Wash first.

The first washed natural salt is applied to a sieve, and water is sprayed from the upper side to perform a second washing to remove foreign matters or suspended matters that are not removed in the first washing process and the particles attached to the surface of the natural salt are relatively small.

By the above washing step, foreign matters such as suspended matter, soil, straw, and sand contained in the natural salt are removed.

2. Dehydration of sun salt

Next, the water and liver water of the natural salt washed in the dehydration step are removed. The washed sea salt is dehydrated by being left in the well-ventilated shade for about 4 to 6 hours. In addition, it is also possible to remove the moisture by rotating the washed natural salt in the dehydrator.

By the dehydration process, the salt water of the sun salt is removed and the salinity is lowered.

3. Drying of Sea Salt

In the dehydration step, a drying step of heating and drying to remove moisture and foreign matter remaining in the dehydrated natural salt is performed. In the drying step, the dehydrated sun salt is put into a heating apparatus and dried by heating until it is completely dried at 130 to 150 ° C.

During the drying step, foreign matter remaining in the natural salt is burned while natural minerals are preserved, and harmful gases such as chloride gas are removed.

4. Kelp Extract

The kelp liquor to be mixed with the dried salt is extracted.

Kelp contains a lot of protein, fat, sugar, calcium, iron, iodine and vitamin C. About 20-24% of minerals are very useful for the human body and improve the taste of salt by improving the taste of salt itself.

Kelp liquor is extracted by heating in a bath. Extraction can be known as direct heating extraction, boiling water extraction, etc., but in order to effectively extract the active ingredients of plants, it is preferable to extract by boiling water extraction.

The clean kelp is finely chopped and placed in a water bath and heated to 100 to 120 ° C. for 4 to 6 hours.

More preferably, the steam is heated for 5 to 10 hours at a temperature of 90 ° C. before extraction of the bath. Steam is supplied at the bottom of the extractor to allow water vapor to exit from the top. This process increases the efficiency of the extraction of the active ingredient of the plants.

After heating in a hot water bath, cool off and remove any insoluble solids such as foreign substances or debris from the filter to obtain kelp extract.

5. Heating step

After completion of the extraction step, 20 parts by weight of the extracted kelp solution with respect to 100 parts by weight of water and 10 parts by weight of the dried natural salt are mixed and heated first to 65 to 75 ℃. Heat the mixture evenly until the mixed sun salt is completely dissolved.

Through the first heating process, water, which is a natural salt as a solvent, is dissolved, and the active ingredient of kelp is uniformly dispersed in the solvent.

After the primary heating, the secondary component is heated to 120 to 140 ℃ to crystallize the salt, the active component of the kelp is impregnated with salt.

As another embodiment of the present invention, in order to add antimicrobial and antioxidant effects to the salt to be prepared in the heating process, at least one extract of the pomegranate fruit extract and the herbal extract may be further mixed with the kelp extract.

Pomegranate is 6 ~ 8cm in diameter, round, covered with hard yellowish skin, and contains many seeds in the flesh. The edible part is about 20%, but the flesh has a sweet and sour taste and the skin is used as a medicine. It is effective in converging, bleeding and hooking the intestines. Pomegranate has an excellent anti-inflammatory and antibacterial effect, which has the effect of enhancing immunity. These pomegranates have the effect of recycling waste resources because they are mainly used and discarded only from the seeds of the fruit.

Pomegranate fruit is ripe in the fall, and then split and the pomegranate fruit shell with seeds and insides removed in a water bath and heated to 120 ~ 140 ℃ to obtain an extract of pomegranate fruit shell.

When the extract of the pomegranate fruit shell is prepared as described above, 20 parts by weight of the kelp solution extracted with respect to 100 parts by weight of water, 10 parts by weight of the extracted pomegranate fruit shell liquid, and 10 parts by weight of the dried natural salt are mixed and the primary and A secondary heating process is performed.

Herbs, on the other hand, add antibacterial, antioxidant, soothing and anti-inflammatory effects to the salt to be prepared, as well as remove bad odors.

Herbs include lavender, rosemary, chamomile, peppermint, spearmint, applemint, eucalyptus, limeblossom, sage, lemongrass, lemon verbena, rosehip, cinnamon, jacquard, sweet fennel, ginger, saffron and echinacea At least one herb selected from the group of herbs including jasmine, caraway, hibiscus and marigold can be used.

In particular, it is desirable to use lavender, rosemary, chemomile, peppermint, sage, which are most effective in removing odors and enriching herb aroma when mixed with the salt to be prepared.

Herb extracts are collected in the form of oils through a steam distillation process. In this case, 20 parts by weight of the kelp solution extracted with respect to 100 parts by weight of water, 1 part by weight of the herb extract, and 10 parts by weight of the dried natural salt are mixed to carry out the first and second heating processes.

As above, there is antibacterial, antioxidant, soothing, and anti-inflammatory effect of pomegranate fruit peel or herb, and salt containing pomegranate fruit peel or active ingredient of herb along with kelp can be useful not only for edible but also for cosmetics such as cleaning agents or bathing agents. have.

In addition, acne, pruritis, athlete's foot, such as athlete's foot, pomegranate fruit and antibacterial, antioxidant, soothing, anti-inflammatory action effectively reduces the symptoms of dermatitis.

And the kelp used in the heating process can be used as a kelp powder obtained by drying and grinding the kelp in addition to the liquid form.

In addition, seaweeds such as shellfish, green seaweed, seaweed, etc. in addition to kelp can be used to add more.

6. Crushing Step

Crystallized salt after completion of the heating step may be used as it is, but may be used by grinding to a predetermined size suitable for the purpose.

On the other hand, the salt production method using the kelp of the present invention according to another embodiment performs the kelp grinding step of obtaining the kelp powder by drying and grinding the kelp after the kelp liquid extraction step described above.

In this case, the water content of dried kelp is preferably within 10% of the total dry weight of kelp.

The kelp powder obtained in the kelp grinding step is subjected to a concentration step of lyophilization by mixing with the kelp extract. Preferably, in order to concentrate the kelp to a high concentration, the concentration process is preferably performed about 2 to 3 times.

The kelp concentrated powder concentrated in the concentration step is mixed with the sun salt dried in the drying step to dry secondarily to prepare a salt using kelp.

Hereinafter, the salt production method using the kelp of the present invention will be described through examples. However, the following examples are only for illustrating the present invention in detail, and the scope of the present invention is not limited to the following examples.

Example 1

First, the sun-dried salt from Jeonbuk Byeonsan Peninsula was placed in a container, stirred with sprayed water, washed twice with water, and then sprayed with water on a sieve to remove foreign substances. After the washing was completed, it was left for about 5 hours in a well-ventilated shade as it is dehydrated and then dried by heating to 140 ℃.

To prepare the kelp extract, finely chopped clean kelp, put it in a water bath, filter it by heating at 110 ° C. for 5 hours, and then filter the resulting kelp solution with respect to 100 parts by weight of water and 20 parts by weight of dried sea salt. Mixing and mixing evenly until the natural salt is completely dissolved at 70 ℃, the first heating and second heating to 130 ℃ to grind to a suitable size to prepare a salt using a kelp.

Looking at the results of Table 1, it can be seen that in the case of Examples 1 to 4 in appearance in terms of appearance, aroma, taste, overall preference is much higher than the comparative example. In particular, it can be seen that the refined salt of the comparative example in the taste has a low salty score of 2.1, and in the embodiments, the saltiness is less and the rich taste of kelp is added to greatly improve palatability. And it can be seen that there is no significant difference in the case of the Examples, but Example 2 was slightly higher score in the flavor.

Therefore, the salt using the kelp of the present invention is less salty than conventional refined salt, greatly improves the palatability and can be usefully used in the human body by adding an effective ingredient. In addition, kelp is added to reduce the side effects of artificial seasonings do not need to add a separate seasoning when cooking food.

Experimental Example 2: Sensory Test

The salts of Examples and Comparative Examples of the present invention were subjected to sensory tests to determine whether they are suitable for cosmetic use. For this purpose, 18 adult men and women were selected and divided into three groups of six. Each group consisted of 2 males and 4 females, and the texture, moisturizing effect, skin irritation, and fatigue recovery were evaluated by five-point scale method.

The salt of Example 1 in the first group, the salt of Example 3 in the second group, and the salt of Comparative Example 2 in the third group were tested in a bath for bath. At this time, 1kg of salt was added to 200 liters of water at 60 ° C. for 30 minutes.

Looking at the results of Table 2, in the case of the first and second groups using the salt of kelp of the present invention as a bathing agent, the salt of Comparative Example 2 as a bathing agent in texture, skin irritation, fatigue recovery, moisturizing effect It can be seen that the score is much higher than the third group used. The salt produced by the embodiment of the present invention was low in salt and vitamins, vegetable fiber and various components contained in the kelp was added to the water when the water texture was good and there was no skin irritation.

In particular, it can be seen that the case of Example 3 containing the herbal extract in the degree of skin irritation, fatigue recovery, and moisturizing effect is effective as a bathing agent, which is relieved of fatigue and stress due to the aromatherapy effect of herbs. It seems to be attributable to the resolution.

Experimental Example 3: Antimicrobial and Anti-inflammatory Effects Experiment

In order to confirm the antimicrobial and anti-inflammatory effects on the salt of the above embodiment, athletes with athlete's foot athletes were selected and tested for the relief of symptoms. Fifteen athletes with common athlete's foot and severe athlete's foot were selected and divided into three groups. And each group was tested by combining three athletes with a common athlete's foot and two very athlete's foot athletes and the results are shown in Table 3 below.

Washing the feet for one month twice a day morning and evening, and then dried to apply the salt diluted salt of Example 2, Example 3 and Comparative Example 2 to the affected area to see the effect. The first group was coated with brine diluted in Example 2, the second group with brine diluted in Example 3, and the third group was coated with brine diluted in Comparative Example 2.

Athlete's state is 0: no athlete's foot, 1: very little, 2: little, 3: normal athlete's foot, 4: severe athlete's foot, 5: very athlete's foot The mean relaxation rate was quantified.

Athlete's foot remission rate = (Athlete's weight before group's experiment-Athlete's foot after group's experiment) / 5,

Here, (Athlete's athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot athlete's foot) Therefore, if the average athlete's foot relaxation rate is 0, it means that the athlete's foot is not treated at all, and 3.8 means that the athlete's foot is cured.

division 1st group 2nd group 3rd group Athlete's foot relaxation rate 1.5 1.2 0

Looking at the results of Table 3, in the case of the first group and the second group using the salt according to the embodiments of the present invention, it can be seen that the athlete's foot athletes symptoms were alleviated to some extent. In contrast, the athlete's foot symptoms were not alleviated in the third group using the salt of Comparative Example 2.

This can be seen that the salt according to the embodiments of the present invention has an antibacterial effect, which relieves athlete's foot symptoms to some extent. In particular, salt containing pomegranate fruit extract was found to be more effective in relieving symptoms. After the experiment, each athlete's foot in the first and second groups was checked for the degree of itching of the affected area, and itching was considerably alleviated and there was no significant irritation or damage to the skin.

From the above results, antibacterial, antioxidant, soothing and anti-inflammatory effects of pomegranate bark and herbs on dermatitis as well as athlete's foot, as well as acne and pruritus, are expected to alleviate the symptoms of dermatitis.
