These R.A.R. were not set up for long term storage. Anytime I find a great price on stuff, I have a tendancy to go hog wild and stock up. She thinks the R.A.R. were in the neighborhood of 3+ years old. We live in AZ so it's not humid for very long, but it gets humid often enough. The little paclets we get in R.A.R. are just paper with a waxy or very thin plastic film on the inside. Not the best to keep the stuff inside dry. I prefer to store plain rice for long term in Mylar aluminized bags with oxygen absorbers, with or without a Nitrogen purge. I store spices in quart Mylar bags, the same way. But don't store table salt with Potassium Iodine. While plain salt (Pickling salt) does not expire, iodized salt has a shelf life of about five years because the stability of the iodized salt decreases over time with exposure, especially in the presence of moisture or metal ions. Morton says the Iodine can disipate.
