Sea Salt Production Process: From Nature to Your Table

Sea salt, known as “white gold”, is an essential ingredient in our kitchens and a product with multiple industrial and medicinal uses. Its production process, although seemingly simple, requires precision, traditional techniques and respect for natural cycles. In this note, we explore the key stages that transform seawater into pure salt crystals, highlighting the importance of this process for both gastronomy and industry.

1. Seawater Capture

The sea salt production process begins with the capture of water from the oceans. This step is carried out in salt flats or coastal ponds strategically designed to allow the controlled entry of seawater. Water quality is essential, so areas free of contaminants are selected to ensure the purity of the final product.

2. Initial Evaporation

The captured seawater is distributed into shallow ponds called "evaporation basins." Here, the water is exposed to the action of the sun and wind, initiating a natural evaporation process. As the water evaporates, the concentration of salts gradually increases. This step can take weeks, depending on weather conditions, and is crucial for the salt to begin to crystallize.

3. Precipitation of Impurities

During evaporation, heavy minerals and other impurities present in seawater begin to settle to the bottom of the pools. This stage acts as a natural filtration system that separates impurities from purer salts. Traditional techniques ensure that this process is carried out in an efficient and environmentally friendly manner.

4. Crystallization

The remaining water, now highly saturated, is transferred to specific pools for crystallization. At this stage, the conditions of sun and wind combine so that salt crystals begin to form on the surface. This is a natural process that requires constant monitoring to ensure that the salt maintains its desired quality and size. The crystals form slowly, capturing the pure essence of the sea.

5. Salt Harvest

Once the crystals have reached the appropriate size, they are harvested. Traditionally, salt is harvested manually using tools such as rakes and shovels to preserve the integrity of the crystals. This artisanal method ensures that the salt maintains its natural properties, such as its mineral content and distinctive flavour.

6. Washing and Drying

After harvesting, the salt undergoes a washing process to remove any residue or unwanted particles. It is then dried in the sun or using controlled drying techniques, depending on the conditions and destination of the product. This step ensures that the salt is ready for packaging and distribution, maintaining its purity and quality.

7. Classification and Packaging

Dry salt is classified according to its size and purity, depending on its final use. It can be used for human consumption, industrial applications, cosmetic products or medicinal treatments. Once classified, it is packaged in different presentations, such as coarse salt, fine salt or flakes, ready to reach consumers.

8. Distribution and Use

Finally, the sea salt produced is distributed locally and internationally. Its versatility allows it to be used not only as an essential condiment in gastronomy, but also in processes such as food preservation, spa treatments, chemical manufacturing and water purification.

Sustainability and Tradition in Sea Salt Production

The sea salt production process is a perfect example of how nature and tradition can work together to deliver a high-quality product. Many salt mines operate using sustainable methods that respect the environment and preserve coastal ecosystems. In addition, artisanal practices ensure that the salt retains its unique properties and cultural impact.

Conclusion

The production of sea salt is a meticulous process that combines the power of nature, traditional techniques and a deep respect for natural cycles. Every grain of salt that reaches your table is the result of careful and sustainable work.
