In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to user's intention or precedent. Therefore, the definition should be made based on the contents throughout this specification.

Salt groundwater taken from Uljin-gun, Gyeongsangnam-do was used as raw water.

Based on 100% by weight of the saline groundwater, it was evaporated until it became 5% by weight, and calcium carbonate (CaCO ₃ ) was removed to prepare a saline groundwater concentrate. The saline groundwater concentrate was crystallized using a spray dryer to obtain salt crystals, and then the salt crystals were freeze-dried to prepare saline groundwater salt. 19 g of saline groundwater salt was obtained based on 1,000ml of saline groundwater raw water. And Figures 1 and 2 are test reports analyzing the components contained in the saline groundwater salt of Example 1.

[Comparative Example 1]

Salt groundwater salt was prepared in the same manner as in Example 1, except that salt was prepared by drying the salt groundwater concentrate obtained by evaporating salt groundwater to 10% by weight in Example 1 by using refined salt and hot air drying.

[Comparative Example 2]

In Example 1, the deep sea water concentrate was used instead of the saline groundwater concentrate, and salt was prepared using the deep sea water concentrate in the currently used manufacturing method.

[Experimental Example 1]

The mineral content of the saline groundwater salt of Example 1, the saline groundwater salt of Comparative Example 1, and the deep seawater salt and sun salt of Comparative Example 2 were measured and listed in Table 1 below, and the unit is [mg / 100g].

As can be seen in Table 1 above, it was confirmed that the saline groundwater salt prepared by the method of Example 1 had a lower sodium content and higher calcium, potassium, and magnesium contents than the saline groundwater salt of Comparative Example 1, More specifically, it was confirmed that calcium was 30% or more, potassium was 250% or more, and magnesium was 50% or more.

Comparing the saline groundwater salt of Example 1 and the deep seawater salt and sun salt of Comparative Example 2, the sodium content of the deep seawater salt and sun salt of Comparative Example 2 was about twice as high as that of the saline groundwater salt of Example 1. , it was confirmed that the minerals contained significantly less.

[Experimental Example 2]

The mineral content of the saline groundwater salt of Example 1 and the salt produced in Korea was compared, and the results are shown in FIG. 3.

Referring to FIG. 3, in the case of salt groundwater salt of Example 1, the sodium content is at least 30% less than domestically produced refined salt or processed salt, and contains a lot of mineral components such as calcium, potassium and magnesium. could confirm that

[Experimental Example 3]

In order to confirm the water quality characteristics of the raw water, the mineral components and hardness of the salt groundwater of Uljin-gun used in Example 1 and the salt groundwater and deep seawater taken from Jeju Island were analyzed by requesting the Korea Testing & Research Institute for Chemical Convergence. The results are shown in the table below. 2, the unit of mineral content is [mg/100g], and the unit of hardness is [mM].
