Does Sea Moss Expire?

Like any other food product, sea moss can expire if it is not stored properly or has been exposed to moisture or other contaminants. However, if sea moss is properly dried and stored in a cool, dry place, it can last for a long time, usually up to several years.

Now that it’s out of the way, the next big question is how to store sea moss gel to extend its life.

You can keep sea moss in the refrigerator to extend its shelf life. 

Whether you are using dried sea moss or in gel form, store it in a clean, airtight container and seal it tightly. Label the container with the date of purchase, so you can be aware of how long it has been in the fridge.

If you wish to keep it fresh for months, try freezing the gel.


How Long Does Sea Moss Last?

There’s no definite answer to how long sea moss lasts. Although its lifespan can depend on some factors like:

  • How it was grown
  • How many preservatives it contains
  • How it’s stored 2
  • Whether it’s fresh or dried

Generally, sea moss gel will last a few weeks in the refrigerator and a few months in the freezer. However, dried sea moss packed in an air-tight container and kept in a dry, cool place can last up to 2 years.

Some factors that may signal that the sea moss gel has expired are:

  • Colour

Food items generally have a specific colour, and changes in them mean they aren’t fit to consume. 3 Similarly, sea moss gel is naturally tan or grey, but if the colour becomes dark or changes shade, the gel might be expired. 

  • Texture

If the sea moss has become extra slimy or more watery than usual, the gel is near its expiry date.

  • Odour 

Sea moss may have a slight ocean-like odour. But if it starts smelling foul, fishy, and too overpowering, it’s time to toss the gel in a bin. 

  • Mould Formation

If you see tiny moulds growing on the surface of the gel, it surely means it’s no longer fit to consume. 


Can You Freeze Sea Moss Gel?

You can freeze sea moss gel to increase its life and keep it fresh longer. 4 Seamoss, like any other food, can be frozen for months to prevent moulding.

This tip is beneficial if you’ve purchased a bigger batch of sea moss and do not want it to go to waste. Just pour the gel into a container or ice tray. Then pop it into the freezer, and you are all set for the coming months.
