Stocking commercially canned foods, long term food storage and home canning always raise the same question. What is the shelf life? I look to University Extension Services for the most accurate research and tested methods. The links below will help answer this question with tested fact. Enjoy and be safe with your food storage and canning!
The shelf life paragraph below is from the Utah State University Cooperative Extension
As a general rule, unopened “Home canned foods” have a shelf life of one year and should be used before 2 years. “Commercially canned foods” should retain their “best quality” until the expiration code date on the can. This date is usually 2-5 years from the manufacture date. High acid foods usually have a shorter shelf life than low acid foods.
For emergency storage, commercially canned foods in metal or jars will remain safe to consume as long as the seal has not been broken. (That is not to say the quality will be retained for that long).
Foods “canned” in metal-Mylar®-type pouches will also have a best-if-used by date on them. The longest shelf life tested of this type of packaging has been 8-10 years (personal communication U.S. Military MRE’s). Therefore, storage for longer than 10 years is not recommended.
