Is sea salt edible?

Quality characteristics:

The collection of sea salt is more complicated than other salts, which can retain more trace elements in seawater, instantly stimulate and retain the original flavor of ingredients, and make them fresh, salty and delicious. It is mainly divided into crude salt, refined salt and flake salt, which are refined by seawater evaporation. The production process of sea salt is complex, the production cycle is long, the production cost is high, and the taste and quality are good.

The quality of sea salt varies from place to place. Hangu Salt Field is located at east longitude117-118 and 39 north latitude. The bottom of the field is covered with sediment, with abundant sunshine, obvious rain and strong seasonal climate. This is the gold producing area of sea salt, which is suitable for drying high-quality sea salt.

Rich in trace elements:

Seawater contains more than 80 kinds of elements, most of which are beneficial elements, because it is a slow process from seawater concentration to sodium chloride crystallization and precipitation, which takes about one year. During this period, most heavy metal elements in concentrated seawater are greatly reduced:

1, heavy metal, deposited and concentrated at the bottom of the pond when seawater is concentrated.

2. Different kinds of algae grow in the primary concentration ponds in coastal areas and beaches, including cyanobacteria, brown algae, green algae, red algae and diatoms. These algae adsorb copper ions, cadmium ions, lead ions, nickel ions, zinc ions, tin ions and copper ions.
