China's salt has a wide range of origins, mainly sea salt, well salt, rock salt and pool salt, etc. Sea salt is produced in the four major salt fields of Liaoning, Shandong, the two Huaihuai and Changlu; well salt is mainly produced in Zigong City, Sichuan Province, Ziliujing; rock salt is mainly produced in Sichuan, Yunnan, Hubei, Hunan, Xinjiang, Qinghai and other provinces.
Salt is an important seasoning, widely used in cooking and food processing, and is divided into mineral salt and sea salt according to its source. Mineral salt is a natural ore obtained from underground salt mines, also known as rock salt. In salt mines, salt rocks are mined and then processed and purified to remove impurities, ultimately forming the table salt we use.
Sea salt is a salt product obtained through the evaporation of seawater. When seawater evaporates under the action of heat and sunlight, the water gradually disappears while the salt gradually concentrates and forms crystallized salt. These crystals are sea salt, which has a natural salty flavor and trace minerals.
Both mineral and sea salt are available in the market. There are also special types of salt, such as powdered salt and spray salt, which are usually made through special processing for optional use.
Precautions for buying salt
1, price and cost-effectiveness: price is not the only standard for measuring the quality of salt, but it can be used as a reference factor. Under the premise of quality assurance, choose the more cost-effective products.
2. Origin and production process: Pay attention to the origin and production process of salt. Some regions have better quality salt mines, more scientific and effective production processes, and the resulting salt is purer.
3. Types of salt: Learn about different types of salt, such as refined salt, rock salt, sea salt, etc., as well as their characteristics and uses. Choose the right type according to your needs and tastes.
4. Additives and preservatives: Check the ingredient list of the product to avoid choosing products with too many artificial flavors, preservatives and other unnecessary additives. It is more beneficial to choose all-natural or additive-free salt.
5. Packaging and preservation: Check whether the packaging of the salt is intact, and avoid choosing packages that are broken, leaking or wet. In addition, pay attention to the storage method and store the salt in a dry and ventilated place to prevent caking and moisture adsorption.
