A Step By Step Process Of How Salt Is Made From Sea
Sea salt making has to undergo a proper process of production. Let’s have an overview of it.
Selection of source and gathering seawater:
The first step of making sea salt is gathering the raw material. It can either be seawater or brine from underground. Seawater is collected from different sources like; oceans, saltwater lakes and coastal areas. These sources are selected because of cleanliness and less pollution. The gathered seawater or brine is shifted into large ponds or pans called salt pans or salterns.
Filtration:
After collecting the seawater, the next step is the filtration. In order to remove the dirt and impurities seawater has to undergo the filtration processes. It ensures a purer base for the production of sea-salt. At this stage, the remaining impurities are removed such as; sand, clay, and the less soluble salts such as calcium carbonate, or chalk, and calcium sulfate are removed.
Transportation to production site:
Then seawater is transported to the production site. It is usually transported by using pipes, channels and trucks.
Evaporation methods:
Solar evaporation is the oldest method in salt production. It is preferred in hot climates and ideally in windy areas. Seawater is gathered into the empty salt pans and ponds then put into the open area to have maximize exposure to sunlight and air.
Natural evaporation:
The salt concentration increases as the sun’s heat and wind evaporate the water. It forms salt crystals.
Salt Crystallization:
The salt concentration increases as the sun’s heat and wind evaporate the water. It forms salt crystals and settle at the bottom of the pans.
Boiling
Heating Process:
In order to speed up the evaporation procedure seawater is heated in big containers and boilers.
Water Evaporation:
When seawater is heated and the water evaporates; salt starts gathering and forming crystals.
Salt Harvesting:
Once a certain salt concentration is achieved, the salt crystals are collected either by hand or using machinery.
Different Types Of Salt Based On Production Regions
Mediterranean Sea Salt:
The salt harvested from the Mediterranean Sea, usually contains trace minerals like magnesium, potassium, and calcium. It’s known for its light and blistering texture.
Atlantic Sea Salt:
The salt gathered from the Atlantic Ocean varies in flavor and minerals based on the specific region of the Atlantic coastline.
Pacific Sea Salt:
Collected from the Pacific Ocean, it might contain different minerals due to variations in water composition and collection methods.
Variances In Texture, Color, And Taste Due To Minerals
Texture:
Sea salts can range from fine to coarse textures. Fine sea salts dissolve quickly and are great for seasoning or baking, while coarse salts are used as finishing touches on dishes.
Color:
The presence of minerals can impart different colors to sea salt. For example, minerals like iron oxide might give salt a pinkish color, while other minerals might give various shades of gray or even black.
Taste:
The sea salt has different taste depending on the minerals. Some salts might have a slightly briny or oceanic flavor due to their origin, while others may have subtle differences in taste based on the minerals present.
Importance Of Purity And Quality Control During Production
Purity for Health and Taste:
To maintain the quality and taste of the sea salt, the production environment and purity of the seawater sources is necessary.
Minimizing pollutants:
Impurities or contaminants in seawater, such as pollutants or residues, can affect the final salt product’s taste and safety. So it’s also very important to minimize the contaminants.
Quality Control Measures:
Regular testing and monitoring of the water source, as well as the salt at different production stages, are implemented to maintain high-quality standards.
Environmental Considerations:
A focus on purity and quality control extends to environmental responsibilities, ensuring minimal impact on the surrounding ecosystem during the collection and production processes.
Conclusion
To cut my matter short, after reading this blog your quest about knowing how is sea salt made, will be satisfied. As covered the step-by-step process of sea salt making, its varied colors and texture depending on the minerals and sources. I have also explained how you can maintain the quality and taste of sea salt. So now you will have better understanding of how sea salt is made.
Frequently Asked Questions
Sea salt is used in spa treatments, natural remedies, and various industries like cosmetics and textiles due to its mineral content.
Sea salt contains trace minerals like magnesium and potassium, which may offer some health benefits in moderation.
It can take several weeks for seawater to evaporate completely and leave behind salt crystals.
