Do popcorn seeds expire?
Do popcorn seeds expire? Dry kernels basically have an indefinite shelf life when stored properly. They stay safe to use for years, but that doesn't mean you will enjoy the same results with 10-year-old kernels as you do with fresh ones. Can popcorn seeds go rancid? Popcorn in most cases doesn't go off or spoil. But it doesn't last forever either. Popped kernels go stale, un-popped ones dry out, and the fat in microwaveable popcorn goes rancid. Dry kernels usually have a shelf life of a year or two, but can last much longer. Can I use expired popcorn kernels?...
