Does salt expire?

The short answer is no, salt does not expire. There are two main reasons why salt might appear discoloured or crystalline. Firstly, the natural minerals in the salt can crystallise over time. If the salt has been left out in the sun, it will crystallise as the salt absorbs the sun’s heat. If salt is stored in humid conditions, it can become mouldy. This can also happen if the salt is stored in an un-ventilated area.

Will salt expire?

Salt doesn’t expire. The crystalline structure of salt does not change with time. This is because salt does not undergo chemical reaction, and therefore, salt does not chemically deteriorate. You can keep salt in a dry place, like a box, to prevent humidity from damaging it.

Does salt expire in the can?

Regular salt, which is often crystallized, will not expire. If you find salt that has a strong chemical odor or tastes different than usual, it’s probably expired. Salt can sometimes crystallize over time, too, and that’s perfectly fine. If your salt is clumping together or is unusually hard, it has probably gone stale.

Does salt expire naturally?

Salt does not naturally expire. Although the mineral structure of salt does change over time, this does not affect its properties or make it unsafe for use.

Does salt go bad?

Salt doesn’t technically expire until it reaches about 6%. We like to think of salt as an ingredient, not a product, so it doesn’t technically expire. However, the vast majority of the salt stocked in your kitchen is sodium chloride, a chemical that does start to lose its potency around 25 years. To ensure maximum flavor and effectiveness, we advise replacing your salt every 6-9 months.
