Of course, sunflower seeds last for a shorter period of time if they are not stored properly. But remember that sunflower seeds, like a lot of other seeds, usually have a best by date and not an expiration date. Because of this, you can safely use them beyond their best by date.
How to tell if Sunflower Seeds are bad, rotten or spoiled?
Practicing proper hygiene and food safety techniques will help prevent foodborne illness.
Since sunflower seeds have a long shelf life if kept dry, it is hard to tell if they have gone bad. The best way is by smell, they will start to smell rancid because of the natural oils breaking down due to their exposure to oxygen. Most current packaging is fairly free of oxygen so unopened packages will remain fresh for longer than opened packages.
The development of mold is uncommon in seeds, but still a possibility so always keep an eye out.
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 Sunflower Seeds to extend their shelf life?
The best way to store sunflower seeds is in an airtight container or bag in the pantry or another cool dark place with a constant temperature. Refrigeration prolongs the shelf life, but store them in a glass or ceramic container as they easily absorb chemicals from plastic which can be harmful.
