Salt is an essential commodity that is inexpensive and easy to store. Pure salt can last indefinitely in a sealed, airtight container. However, once opened, it can absorb moisture and odours, leading to clumping and unpleasant flavours. Therefore, it is important to choose the right container for storage. While plastic bags are not recommended for long-term storage due to their susceptibility to tears and moisture, some people keep the salt bags inside plastic containers to prevent punctures and protect the salt from humidity. Glass jars, food-grade buckets, and vacuum-sealed bags are also popular options for maintaining salt's freshness. Additionally, storing salt in a cool, dark, and dry environment helps preserve its quality.

What You'll Learn
Plastic bags are not ideal for long-term storage
Additionally, plastic bags may not provide adequate protection from humidity, which can cause salt to harden and form lumps. To maintain the quality of the salt, it is advisable to transfer it from the plastic bag to a more durable and airtight container. Glass jars, food-grade buckets, and sealed clay pots are recommended alternatives that offer better protection against moisture and odour absorption.
The choice of container depends on the type of salt and its intended use. For example, iodized salt is sensitive to sunlight, so it should be stored in a dark environment to prevent the loss of iodine. On the other hand, sea salt and specialty salts may have unique storage requirements due to their mineral content. Regardless of the container chosen, maintaining a cool, dry environment is crucial to preserving the salt's freshness and preventing clumping.
Furthermore, salt is susceptible to absorbing odours from its surroundings. Storing salt in an airtight container helps mitigate this issue by limiting its exposure to airborne odour particles. By prioritising airtightness and moisture protection, individuals can ensure the longevity and quality of their stored salt.
Overall, while plastic bags may be convenient for temporary storage, they are not ideal for the long-term storage of salt due to their susceptibility to degradation, tears, and inadequate protection against moisture and odours. Transferring salt to more durable containers, such as glass jars or food-grade buckets, is a recommended practice to maintain the freshness and quality of the salt over extended periods.

Salt should be stored in an airtight container
Salt is a basic commodity necessary for life and is inexpensive and easy to store. Pure, natural salt doesn't expire, but it can get clumpy and develop a funky flavour if stored incorrectly. Salt is sensitive to a variety of environmental factors, so it's important to store it in an airtight container.
Salt can be stored in a variety of airtight containers, including glass jars, food-grade buckets, vacuum-sealed food storage bags, and sealed clay pots. Some people also store salt in plastic containers or buckets, but it's important to note that salt can interact with some plastics, so it's best to choose containers meant for food storage. If you're storing salt in a plastic container, it's a good idea to keep it in its original bag to provide extra protection from moisture.
It's also important to store salt in a dark environment, as heat and light tend to go hand in hand, and heat and humidity often go together as well. By storing salt in a dark place, you reduce the chances of it being exposed to heat and humidity. This is especially important for iodized salt, which loses a lot of its iodine when exposed to sunlight.

Glass, wood, and plastic containers are all options
Glass jars with airtight lids, such as wide-mouth Mason jars, are a popular choice as they are relatively inert, dishwasher-safe, and effective at controlling humidity. Some people also use wooden salt boxes, but these may be more for show as salt does not hold well in them. Plastic containers can also be used, especially if they are designed for food storage and are inert. Plastic lids or a layer of parchment paper between the lid and the salt can also help keep moisture out.
For long-term storage, it is recommended to avoid plastic bags as they can break open or tear, and they become brittle over time. Instead, consider using Mylar bags, food-grade buckets, or sealed clay pots. If using a bucket, you can keep the salt in its original bag inside the bucket for added protection against moisture.
Additionally, it is important to store salt in a cool, dry, and dark place to prevent exposure to heat, light, and humidity. This is especially important for iodized salt, which loses iodine when exposed to sunlight.

Keep salt in a cool, dry, and dark place
Salt is hygroscopic, meaning it has the ability to absorb moisture from the air. This can cause salt to clump together and make it difficult to use. To prevent this, salt should be stored in a cool, dry, and dark place.
Firstly, salt should be stored in a cool location. Heat can cause condensation, making salt clumpy. Therefore, salt should be kept away from heat sources such as stoves or ovens. A cool pantry or kitchen cabinet is a suitable location for storing salt.
Secondly, salt should be kept in a dry place. If salt is exposed to water or high humidity levels, it is more likely to become damp. To prevent this, salt should be stored in an airtight container, such as a glass jar with a sealable lid. Metal containers should be avoided as they can rust. While plastic containers are an option, some people believe they could infuse chemicals into the salt.
Finally, salt should be stored in a dark place. Light exposure can cause heat and humidity, which can affect the quality of the salt. Additionally, iodine in iodized salt can be lost when exposed to sunlight. Therefore, salt should be kept away from direct sunlight and stored in a dark pantry or cabinet.
To further prevent moisture absorption, drying agents such as rice, coffee beans, or paper towels can be placed inside the salt container. Additionally, strong-smelling ingredients such as parsley, cloves, or coffee beans can be added to infuse the salt with a pleasant aroma.

Salt is sensitive to environmental factors like heat and humidity
Iodized salt loses a lot of its iodine content when exposed to sunlight, heat, and humidity. The WHO calculated the recommended level of iodine concentration in salt, taking into account a 20% loss during manufacturing and transportation and a further 20% loss during cooking. The actual availability of iodine in salt depends on its form of fortification and environmental factors.
Salt with potassium iodide loses a significant amount of iodine when exposed to sunlight, wind, and other environmental factors. Exposure to heat, light, and moisture decreases the iodine content in all iodized salt, depriving consumers of sufficient iodine in their diet. Moisture in the salt or absorbed from the air by impurities can convert potassium iodide into elemental iodine, which then evaporates.
To maintain the iodine content in iodized salt, it is important to store it in a cool, dry, and dark environment. Covered containers and dry storage help prevent iodine loss. Exposure to sunlight and high temperatures during storage also contribute to low iodine levels in salt.
In summary, salt is sensitive to environmental factors, especially heat and humidity. Iodized salt is particularly vulnerable to these factors, as it can lose its iodine content. To preserve the quality and nutritional value of salt, it is essential to store it in airtight containers in cool, dry, and dark conditions.
