- How long does an unopened can of shortening last? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of unopened shortening, store in a cool, dry area.
How long does an unopened can of shortening last at room temperature? Properly stored, an unopened can of shortening will generally stay at best quality for about two years.
Is unopened shortening safe to use after the "expiration" date on the can? Yes, provided it is properly stored, the can is undamaged and there are no signs of spoilage (see below) - commercially packaged shortening will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the shortening will remain at peak quality.
How can you tell if shortening is bad or spoiled? The best way is to smell and look at the shortening: if shortening develops an off odor, flavor or appearance it should be discarded.
