Can Canned Food Last 100 Years?
Canned food is a great way to store meals and snacks for long-term use. But how long can canned food actually last?
Many people wonder if canned food can last up to 100 years. The truth is, it depends on a few factors.
Canned food has a shelf life of two to five years when stored at room temperature in a cool, dark place. This is because of the metal in the cans, which can corrode over time and cause bacteria to form. If you store your canned goods in moist or hot conditions, the shelf life will be even shorter.
However, canned goods are still safe to eat after the expiration date has passed as long as they’re stored properly. If you open a can and it smells or looks bad, then it’s best not to consume it. If it looks, smells, and tastes okay then it should be safe for consumption.
It is possible for some canned goods to last up to 100 years if they are properly preserved and stored in ideal conditions—namely cool temperatures between 45 and 70 degrees Fahrenheit with low humidity levels (around 35-40%). However, this kind of storage requires specialized facilities that most people don’t have access to.
In order for cans to last 100 years without going bad or becoming unsafe for consumption, they must also remain unopened during that entire time period. Once opened, they must be refrigerated immediately and cannot be left out at room temperature anymore or the bacteria inside will start growing quickly again.
Overall, it is possible for some canned goods to last up to 100 years if they are stored properly and remain unopened throughout that time period; however, this kind of storage isn’t something most people have access to on a regular basis so it’s best not to count on your cans lasting that long in most cases.
Conclusion: While some cans may be able to last up 100 years if stored correctly in ideal conditions with low humidity levels between 45-70°F and remaining unopened throughout that time period; this type of storage isn’t something most people have access too so it’s best not rely on cans lasting that long in most cases.
