Storing salt in your fridge may seem like an odd practice, but there are actually several reasons why some people do it. Some people believe that refrigerating the salt will help keep its flavor fresh while others feel that storing it in a cool place will actually extend the shelf life of the product. Still others believe that refrigerated salt is less likely to absorb moisture, which can cause clumping or even small pieces breaking off and becoming unusable. The truth is there hasn't been much research done on this topic and many of these theories are simply anecdotal evidence that has been passed down through generations.
Salt is hygroscopic, which means that it absorbs moisture from the air. If you leave salt out in a room with high humidity, it can easily pick up water and become clumpy or even dissolve completely. Refrigerating your salt helps prevent this from happening by keeping the environment dryer inside of your refrigerator than it would be in an open cabinet or jar on your countertop.
The other reason people store their salt in the refrigerator is because storing it at room temperature makes it more likely for dirt or other particles to stick onto its surface--which means less flavor!
Others believe that refrigerating salt actually results in more rapid clumping. This is because the moisture in your kitchen air can quickly cause salt to clump, and if you keep it in a sealed container (like a jar), the moisture will not be able to escape. If you leave it out on the countertop, however, this will happen much faster without any help from your refrigerator's air conditioner.
Some people think that refrigerated salt is simply less susceptible to moisture, which can cause clumping--but this isn't necessarily true! As mentioned above: when you open up a bag of table or Kosher salt and sprinkle some onto your food at room temperature (rather than putting it into an airtight container), it will still clump up over time even though its been kept chilled inside of an insulated box with vents on either end meant specifically for letting hot or cold air flow through them freely
Still other people believe that refrigerated salt is simply less susceptible to moisture, which can cause clumping.
But if you're worried about your salt getting damp and clumping up, there's a simple solution: just add some cornstarch or flour to the bag before sealing it up tight in a plastic container. The cornstarch will help absorb any moisture that might get into your container over time so that it doesn't affect your seasoning at all.
The refrigerator is designed to preserve food by reducing the amount of air that surrounds it and lowering its temperature. This preserves the freshness of your salt, preventing it from absorbing moisture from the surrounding environment or developing impurities.
That's because when salt is exposed to air for extended periods of time, it absorbs moisture from the air as well as dirt and other particles. This can cause your salt to clump together into a hard mass that won't easily dissolve in water.
It's important to note that this doesn't happen with all types of salt--only those that are hygroscopic (which means "attracting water"). For example, table salt will absorb moisture but not stick together like kosher or sea salt does if you leave it out on your countertop for too long; however, if you store these kinds of salts in your pantry where they're not exposed directly to air flow (like under a cabinet or behind some jars), then they may become clumped together after several months' time due to absorption from nearby objects like cardboard boxes or aluminum cans nearby them in storage space rather than just being left out on open shelving where air could freely circulate around them all day every day without interruption throughout its lifespan
There are many reasons why some people store salt in their fridges; however there doesn't seem to be any scientific evidence behind any of them.
The main reason for storing salt in the refrigerator is because some believe that it will help retain its flavor and prevent it from clumping. Others believe that refrigerated salt is simply less susceptible to moisture, which can cause clumping. While this may be true, we did not find any research supporting these claims or any evidence showing that storing your salt at room temperature will lead to a decrease in quality over time as compared with refrigerating it (or vice versa).
The bottom line is that there's no real reason why you should store salt in your refrigerator. It won't help it to retain its flavor or prevent clumping, but it will keep it free of impurities and moisture. If you want to ensure that your salt stays fresh as long as possible without having to replace it often then a container with an airtight seal would be ideal for this purpose
