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.

According to most manufactures of SunButter, is good for at least one year from the date of manufacture (if there is no best before date). Seeds can be frozen, but it is not really recommended. They will acquire moisture over time which will make them soggy and generally less desirable.

Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
