Description

METHOD FOR PREPARING SALT THEREOF BY USING BAMBO BY PRODUCT AND METHOD FOR PREPARING THE SALT OBTAINED WITH BALANCE

The present invention relates to a method for producing a salt using bamboo by-products such as bamboo shoots, bamboo shoots, kills, bamboo, and bamboo stalks, and a salt obtained by the method.

Salt is a salty taste, which is a mixture of sodium chloride (NaCl) and minor components such as magnesium, calcium, potassium, boron, strontium, bromine and chlorine.

Salt is present in body fluids, and it regulates water in the body through osmotic action, helps digestion, keeps body fluids alkaline, and also acts as buffer to maintain acid and alkali equilibrium. In particular, sodium regulates blood flow and blood pressure and is involved in nerve stimulation delivery processes.

Salt is essential for life, but overdosing can lead to hypertension, kidney disease and heart disease.

Salt is also obtained from mining rock salt in Europe and North America, but about 3% of the sea water is composed of salt, and it is obtained from sea water in Western Europe and Korea through the sun salt method. Salt can be produced artificially.

The salt of the sun was not purified and mixed with impurities, so it was once classified as a mineral. In 1992, it was excluded from food circulation and its use as food was limited. However, in 2005, the ingredient analysis was carried out and it was recognized as food again. Nevertheless, it contains many impurities and has been processed and refined in various ways.

Such refined salt or salt formulations contain only pure NaCl, which limits the ability to satisfy various consumer needs for palatability and functionality.

Recently, Korean Patent Laid-Open No. 2005-0102320 discloses a complex seasoning which improves simplicity and functionality by mixing garlic and bamboo salt, and Korean Patent No. 466579 Discloses a functional salt mixed with chitosan, and Korean Patent No. 383389 discloses a functional salt in which a mineral such as sodium gluconate is mixed. Korean Patent Laid-Open Publication No. 2006-0068571 discloses a salt water for seasoning so that the solubility can be easily adjusted during seasoning of soup, and Korean Patent No. 799280 discloses a method for preparing seaweed salt using seaweed extract And a functional salt in which the contained minerals are mixed.

On the other hand, bamboo is killed, bamboo shoots, bamboo leaves, bamboo leaves, bamboo leaves, and various other byproducts are utilized. Among them, bamboo leaves have a cold taste and flavor. Bamboo leaves are peeled and detoxified. It has been reported that pharmacological effects such as coughing, sputum dissolution, fever reduction, pesoteridic acid, heavy middle blood pressure, and hypertension are excellent (Kwon, Heung-heon, 1997. Dictionary. 2004, 36 (2): 306-310)

In a recent study, there was an increase in phenol content, amino acid content, and amino acid content in bamboo shoots (Kim et al., 1996, 25 (1) (Korean J Food Sci. Technol., 1995, 27: 1035-1038), and it has been reported that alcoholic liver damage and alcoholic liver damage can be prevented by inhibiting the growth of Staphylococcus aureus and Pseudomonas aeruginosa, It is known that it has hyperlipidemia-inhibiting activity (Lee, Jae Man, Thesis, Daegu Haany University 2011).

It is also reported that bamboo leaves contain minerals such as K, Ca, Mg, Na, Fe, Mn, Zn, and P as shown in Table 1 below (Korean J. Postharvest Sci. Technol. 4): 469-474).

The present invention discloses a method for producing salt in which components of bamboo by-products such as bamboo leaf, bamboo shoot, kill, etc. having various minerals are infiltrated with various pharmacological effects.

An object of the present invention is to provide a salt impregnated with a component of bamboo by-products such as bamboo shoots, bamboo shoots, kills, bamboo stalks, and bamboo stalks.

Another object of the present invention is to provide the salt obtained by the above method.

As shown in the following Examples and Experimental Examples, the present inventors put salt in a hot water extract of bamboo leaf extract, bamboo shoot hot water extract, kelp hot water extract, bamboo hot water extract and bamboo stem for 24 hours, When the components of the hydrothermal extract are allowed to permeate into the salt and then the water is evaporated by heating the mixture of the bamboo by-product hydrothermal extract and the salt and / or the salt is produced by evaporating the water by allowing it to stand in the natural state, The color of the branches and the color saturation (sharpness of color) was achieved with salt. The present inventors believe that the penetration degree of the pigment component will function as a marker showing the degree of penetration of other components of the water extract of bamboo by-product.

The method of producing salt using the bamboo by-product of the present invention comprises the steps of (a) mixing a salt water with a water extract of bamboo by-product, allowing to stand in a natural state, and (b) And evaporating water from the mixture of the aged salt and the bamboo by-product water extract to obtain a solid residue.

As used herein, "bamboo by-product" means one of bamboo leaves, bamboo shoots, bamboo shoots, bamboo shoots (bark wrapping bamboo shoots), and bamboo stalks. These bamboo by-products can be obtained from bamboo belonging to Phyllostachys, bamboo belonging to Arundinaria, bamboo belonging to Sasa, or bamboo belonging to Pseudosasa, , ≪ / RTI > crown, cotton or saris.

In the present specification, the "water extract of bamboo by-product" refers to a product obtained by immersing three drops or powder of bamboo by-products in water and left standing, stirring or heating. Preferably refers to the hot water extract used in the following examples. This extraction can be carried out until the bamboo components are no longer extracted (i.e., the turbidity of the extract is not thicker).

In this specification, "natural state" means a state in which no artificial manipulation is applied to temperature, humidity, and the like.

The meaning not specifically defined in this specification refers to a Korean word meaning or a meaning commonly used in the art.

In the method of the present invention, the salt which can be used in step (a) can be used both as a salt of mannitol and a salt of mannitol. However, considering the preference of the consumer, refined mannitol (referred to as normal mannitol) .

In the method of the present invention, in the step (a), the mixing of the salt and the bamboo by-product water extract may be performed until the salt is saturated and does not precipitate. Mixing to such an extent that it is saturated and not precipitated can be determined within the ordinary skill of a person skilled in the art.

In the method of the present invention, the step (a) of leaving and aging in a natural state may be a period during which the dye component of the bamboo by-product water extract can be sufficiently penetrated into the salt (that is, During the period during which the penetration of the pigment component of the water extract of the bamboo by-product into the salt can be saturated). The period during which the penetration of the coloring component of the water extract of bamboo by-products into the salt can be saturated is until the color of the salt is no longer darkened due to penetration of the coloring matter component. As the step of neglecting and aging proceeds, the coloring matter of the water extract of bamboo by-product penetrates into the salt, and the color of the water extract of the bamboo by-product gradually becomes realized. When the color of the salt does not become dark after a certain time . It is preferable that the step of neglecting and aging proceeds to this point. Such a point confirmed by the present inventors is about one month after mixing the water extract of salt and bamboo by-product as in the following examples. As described above, the present inventors believe that the degree of penetration of the dye component will function as a marker showing the degree of penetration of other components of the water extract of bamboo by-product.

In the method of the present invention, the step of evaporating water in the step (b) to obtain a solid residue is preferably performed by first conducting a heat evaporation process, and then performing a vaporization process in a natural state.

This is because, as shown in the following examples and experimental examples, it is confirmed that when the solid residue is obtained through the heating and evaporation process, the penetration of the coloring component is more increased than when the solid residue is obtained only by the natural state evaporation process (That is, it is confirmed that the color is thicker). The inventors of the present invention believe that the water vapor evaporates and the penetration of the pigment component into the salt becomes easy due to the pressure of the water vapor. However, when a solid residue is obtained only by the heating and evaporating process, coloring components contained in the water extract of the bamboo by-product are carbonized to darken the color and reduce the saturation (sharpness of color) as shown in the following Examples and Experimental Examples .

Considering the above, when the step of obtaining the solid residue by evaporating the water of the step (b) is carried out in parallel with the heating evaporation process and the natural evaporation process, the heating evaporation process is a process in which the components of the bamboo by- It is preferable to perform the process until the point of time when

In addition, in the method of the present invention, bamboo powder and / or bamboo stalks are added to a mixture of the salt and the bamboo by-product water before the step of evaporating the water of step (b) to obtain a solid residue (i.e., after step (a) It is preferred that a step of mixing the powder is added. This is because when the step (b) is performed after the powders are added as shown in the following examples and experimental examples, the degree of coloring of the salt becomes high. Instead of bamboo leaf powder, bamboo leaf powder aqueous solution or bamboo leaf water extract may be used. It is also possible to use an extract of a solid component obtained by evaporating water as the extraction solvent from the water extract of bamboo leaves instead of the bamboo leaves water extract. It is also possible to use an extract of the solid component obtained by evaporating water as the extraction solvent from the aqueous solution thereof, the water extract solution thereof or the water extract solution of the bamboo stem instead of the bamboo stem powder. The addition amount of the bamboo leaf powder or the like may be added until the bamboo powder or the like is added and saturated. I. E., Saturated, until a precipitate is formed. Bamboo powder, bamboo powder, bamboo shoot powder, etc. may be used in addition to bamboo leaf powder or bamboo stem powder. However, these bamboo by-products have a disadvantage in that the color is low and the degree of coloring is low. Therefore, in the following Examples and Experimental Examples, only bamboo leaf powder and bamboo stem powder were used.

Further, in the method of the present invention, after the evaporation step (b), an aqueous solution of bamboo by-product water or an aqueous solution of bamboo by-product powder is added to the obtained solid residue, and the water- The step of obtaining a residue of the solid content by evaporation can be repeatedly added from one time to a maximum of four times. This is because as the examples and experimental examples shown below show, the more repeatedly these steps are, the higher the degree of coloring becomes. Likewise, bamboo powder, bamboo stem powder, aqueous solution of bamboo powder, aqueous solution of bamboo stem powder and the like may be added to the aqueous solution of the bamboo by-product or the aqueous solution of the bamboo by-product powder, or may be added until the precipitate is formed .

In another aspect, the present invention relates to salt using bamboo by-products obtained by the above-described process.

The salt of the present invention can be understood as a salt into which components such as bamboo by-product dye are permeated by the method described above.

As described above, according to the present invention, it is possible to provide a method for producing salt using bamboo by-products and a salt obtained by the method.

Hereinafter, the present invention will be described with reference to Examples and Experimental Examples. However, the scope of the present invention is not limited to these examples and experimental examples.

<Examples 10 to 17> Preparation of the salt using a bamboo-products Examples 10 - 18

As in the above Examples 2 to 9, salt was produced using bamboo by-product, and instead of bamboo powder, bamboo stem powder was added to the mixture of the salt of bamboo and the hot water extract of bamboo by the same amount, .

< Experimental Example > Sensory evaluation of appearance (color and saturation)

Sensory evaluation was performed on the appearance of the salt, that is, the hue and saturation (darkness and lightness of color) obtained in the above <Examples 1 to 9>. The sensory evaluation for color and saturation was performed because it was determined that the higher the color of the salt obtained in the above Examples and the higher the saturation (sharpness), the higher the degree of impregnation of the component of the bamboo by-product with the salt, It is because it is.

Since the bamboo powder was mixed in all the examples in the second and third steps regardless of the bamboo by-product hot water extract solution used in the above examples, the color and the saturation of the obtained salt were evaluated by the bamboo powder aqueous solution The light brown color of the aqueous solution of the pale green or bamboo stem powder was evaluated.

The scale of the evaluation indicates that up to 5 points can be obtained when the aqueous solution of the bamboo leaf powder or the aqueous solution of the bamboo stem powder is judged to reproduce the original color and the color saturation of the bamboo stem powder in the color different from the original color of the aqueous solution of the bamboo leaf powder or the aqueous solution of the bamboo stem powder ), The higher the degree of discoloration, the higher the value of 9 points.

Specific evaluation scales are as follows.

1 point: The original color and saturation are very weak.

3 points: The original color and saturation are weak.

5 points: It is close to the original color and saturation.

7 points: The original color was slightly discolored.

9 points: The original color was very discolored.

The sensory evaluation was performed on 20 sensory evaluators who fully understood the purpose of the evaluation. The results are shown in Table 4 below as the average value of the evaluations of the sensory evaluators.

Sensory evaluation result division Sensory evaluation result (average of score) Example 1 6.54 Example 2 8.42 Example 3 2.55 Example 4 3.32 Example 5 3.74 Example 6 4.06 Example 7 4.22 Example 8 4.27 Example 9 2.13 Example 10 8.23 Example 11 2.24 Example 12 3.16 Example 13 3.54 Example 14 3.86 Example 15 4.12 Example 16 4.24 Example 17 1.92

The results of the above Table 4 show that when the water is evaporated by heating only after aging, discoloration occurs due to the carbonization of the components of the bamboo by-product when the salt is produced (see Example 1) The bamboo stem powder and the bamboo stem powder are added to the salt to make the degree of discoloration becomes higher (see Example 2 and Example 10).

In addition, in the case of producing salt by evaporating water in a natural state without a heating evaporation process (see <Examples 3 and <11> above), omitting the aging process and heating evaporation process and natural evaporation process In the case of producing salt (see Example 9 and Example 17), the degree of coloring is low.

In addition, the degree of coloring is high when the aging process, the heating evaporation process, and the evaporation process in the natural state are all carried out (when the bamboo powder is added, see the comparison between Example 3 and Example 4, (See Example 11 and Comparative Example 12).

In addition, it is shown that the degree of discoloration is continuously increased when the hot-water extract of bamboo leaf with bamboo leaf powder or the hot water extract of bamboo stem with bamboo stem powder is repeatedly heated and evaporated in a natural state (bamboo powder added Examples 13 to 16 in the case of adding bamboo stem powder were compared with those in Example 12 and Comparative Example 14, Compare).
