Sea salt vs. traditional kitchen salt: what are the differences?

Salt is not just a flavor enhancer—it also improves the texture, preservation, and storage life of food. When people talk about food-grade salt, they often think of traditional kitchen salt (vacuum salt). Yet sea salt is a fully sustainable alternative, offering numerous benefits for both the kitchen and the environment. Here’s what sets them apart.

How Is Sea Salt Extracted?

Sea salt is harvested naturally by evaporating pure seawater in salt basins. Sun and wind slowly form a natural salt crust, which is then mechanically collected. This method is ecological, sustainable, and energy-efficient, making sea salt an environmentally responsible choice.

Characteristic features of sea salt:

• Natural coarse grains for a crunchy texture.
• Rich in minerals and trace elements absent in vacuum salt.
• No chemical additives—just pure salt.

After washing, drying, and sieving, sea salt is ready for use in kitchens, combining natural goodness with exceptional taste.

How Is Vacuum Salt Extracted?

Vacuum salt, often labeled as traditional kitchen salt, is mined from underground salt layers. Water is pumped into the salt deposits to create a brine solution, which is then brought to the surface and chemically purified to remove unwanted minerals. This brine is boiled to crystallize fine, white salt grains.

Key points about vacuum salt:

• Primarily produced for the chemical industry (>60% used for chlorine and lye production).
• Energy-intensive extraction process.
• Causes soil erosion in underground layers.
• Often contains anti-caking agents (E535 or E536).

As a result, vacuum salt has a larger carbon footprint compared to sea salt.

Sea Salt vs. Vacuum Salt: Main Differences

Although both salts are mainly sodium chloride, sea salt offers a richer composition thanks to its natural extraction process:

• Mineral content: Magnesium, calcium, and trace elements add subtle flavor.
• Grain variation: Fine or coarse grains suit a variety of food applications—bread, snacks, dairy, and spice mixes.
• Additive-free: Sea salt is naturally free of anti-caking agents.

High-quality sea salt can replace vacuum salt 1:1 in most culinary applications. Historically, vacuum salt was more widely used due to geographical proximity to producers, whereas Mediterranean sea salt needed longer transport. Moses addresses this with strategically located facilities in Ghent and Roeselare, including the largest indoor salt terminal in Europe.
