According to relevant data, China's salt mainly comes from sea salt and well salt, of which sea salt is mainly produced in coastal areas, while well salt is mainly distributed in inland areas. In the history of China, the mining and utilization of well salt and sea salt have been for a long time, but with the development of science and technology and the growth of population, the output of sea salt has far exceeded that of well salt and has become the main salt in China.
China's coastal areas have vast salt pans that convert seawater into table salt by drying salt. Sea salt has a relatively low production cost and stable quality, so it occupies a considerable share of the Chinese salt market. In addition, sea salt can also be processed into various salt products, such as iodized salt, low-sodium salt, etc., to meet the needs of different groups of people.
In contrast, well salt has a longer history of exploitation and utilization. In ancient times, well salt was extracted from underground brine by drilling wells. Well salt is characterized by a high iodine content, so well salt has been an important iodine supplement in the past**. However, with the development of modern science and technology, the mining cost of well salt has gradually increased, and the output has also decreased year by year. At present, well salt accounts for a very small proportion of China's salt market.
In general, the main salt in China is sea salt, but well salt has also played an important role in history. With the development of science and technology and the growth of population, the production and market share of sea salt will continue to increase. At the same time, in order to meet the needs of different groups of people, China will continue to launch a variety of new salt products.
