Abstract: There is provided a liquid vegetable salt preparation method which can obtain liquid vegetable salt having a low salinity, a high mineral content and little heavy metals harmful to the human body. To obtain the liquid vegetable salt, a halophilious plant is gathered and impurities are removed therefrom. Thereafter, it is cleaned and chopped or crushed, and then hydrothermal extraction is performed to obtain an extract. This extract is compressed to get only the juice, thereby obtaining the liquid vegetable salt containing a large amount of free amino acid.

Abstract: There is provided a vegetable salt preparation method which can obtain vegetable salt having a low salinity, a high mineral content and very little heavy metals harmful to the human body. To obtain the vegetable salt, a halophilious plant is gathered and impurities are removed therefrom. Thereafter, it is cleaned and chopped or crushed, and then hydrothermal extraction is performed to obtain an extract. This extract is dried and sequentially passes through the first ashing at 150-250° C. for thirty minutes, the second ashing at 500° C. for two hours or longer and the third ashing at 700° C. for longer than two hours, and then pulverized, to thereby obtain the vegetable salt having uniform granules.
