If you’re saving the seeds to re-plant, store them in an airtight container in a cool, dry place until you are ready to plant. The container should be labeled with the variety and the harvest date. The seed will last a long time if it is stored this way. Before planting the seeds should be dried for several hours or overnight.

Should sunflower seeds be refrigerated?
Store your seeds in a dry place away from the sun, sealed tightly in a container or bag. If you want to prolong their shelf life, you can store them in your refrigerator or in the kitchen.
Sunflowers can be stored at room temperature for up to two weeks. If you are storing them for longer periods of time, be sure to keep them covered with a plastic bag to prevent them from drying out.
How long can sunflower seeds be stored?
Researchers with brazil’s revista ciencia agronomica found that sunflower seeds can be stored in a cool, dry room, in a refrigerator, or in an airtight container for 12 months.
The study, published in the Journal of Agricultural and Food Chemistry, was conducted by researchers from the University of São Paulo (UPMC) in Brazil and the Universidade Federal do Rio Grande do Sul (UFRS), in Rio de Janeiro, Brazil.
The research was funded by the Brazilian Ministry of Agriculture, Livestock and Fisheries, the U.S. Agency for International Development (USAID), the European Union’s Seventh Framework Programme (FP7/2007-2013), and a National Science Foundation (NSF) Graduate Research Fellowship.
Do raw sunflower seeds go bad?
Although typically dried seeds are pretty stable, they will go bad after a while. The quality and shelf life of the seeds can be extended by keeping them dry. If the seeds are rancid, moldy, smell bad, and taste bad, they should be thrown away.
If you’re not sure what to do with your seeds, you can use them in a variety of ways. You can eat them raw, add them to soups and stews, or roast them as a side dish. They can also be used in baked goods such as breads, muffins, cookies, cakes, pies, etc.
Can I freeze sunflower seeds?
Can you freeze sunflower seeds? Yes, freeze sunflower seeds in airtight containers or heavy-duty freezer bags. How long do the seeds last in the freezer? sunflower seeds will remain safe to eat for up to a year if they are properly stored. Sunflower seed bags should be stored in a cool, dry place, away from heat and light.
Do not store in direct sunlight, as the seeds can be damaged by direct exposure to the sun’s rays. If you must store them, place the bags in an air-tight container or freezer bag and cover tightly with plastic wrap. Keep the bag tightly sealed until you are ready to use them.
Should sunflower seeds sink or float?
The water test can be used to check for seed viability. Put the seeds in a container of water. The seeds need to sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they will not germinate. Another method is to soak the seedlings in water for a few hours. The seeds should float to the surface, but they should not be completely submerged.
Seedlings that are soaked for long periods of time are more likely to die than those that were not soaked at all. You can also check the germination rate of your seeds by placing them on a piece of paper towel and letting them sit in the sun for 10 minutes or so. This will give you an idea of how long it will take for them to grow.
How can you tell if sunflower seeds have gone bad?
Since sunflower seeds have a long shelf life, it’s hard to tell if they have gone bad. They will start to smell rancid because of the exposure to the air, the best way is by smell. Sunflowers can be stored in the refrigerator for up to three months. They can also be kept in an airtight container in a cool, dry place for a few weeks before eating.
