Of course, nori (dried seaweed) lasts for a shorter period of time if it is not stored properly. But remember that nori, like a lot of other vegetables, usually has a best by date and not an expiration date. Because of this distinction, you may safely use nori to compliment your favorite meals even after the best before date has lapsed.
How to tell if Nori is bad, rotten or spoiled?
Practicing proper hygiene and food safety techniques will help prevent foodborne illness.
Beware of any changes in color, texture or aroma; but if seaweed remains dry it should be crisp and fine for a long time. The seaweed may become more of a yellowish or brown color and/or loose its flavor when gone bad. If the seaweed becomes moist it can be toasted to re-gain crispness, but remember that extended moisture can invite mold.
There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!
How to store Nori to extend its shelf life?
You can help keep nori fresh by keeping it re-sealed either in its original container, a zip-lock bag or a tightly sealed glass jar along with the "do not eat" package of silica gel that absorbs moisture so that the seaweed will stay dry. In humid environments, you may want to freeze your nori for extended shelf life. Refrigeration is not recommended because of the added moisture. Foods freeze indefinitely, but the quality declines over time.
Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
