How can canned nacho cheese sauce be preserved once opened?

Answer 1

About 2 years.

Look on the jar or can, there should be an expiration date. Many people don't realize that canned/jarred foods have an expiration date on them. Even foods such as canned vegetables, evaporated milk, etc. have expiration dates on them.

Also, always check the can for signs of bulging, especially on tomato products. If there is even the slightest sign of bulging, THROW IT OUT! Botulism is the most dangerous form of food poisoning there is, and is more common with tomato products.

Answer 2

Do not store the pasta sauce in the can once it is opened. The acids in the sauce will start to react with the can.

If you move the sauce to a storage container and refrigerate it, it might last up to one week.

Answer 3

Less then a few days. Best way to save it is to repackage it and freeze. Refrigeration works too but for only for a week or two at most.

Answer 4

You should store opened cheese sauce in a sealed jar or container in the refrigerator to preserve it. It can also be frozen in a sealed container.

Answer 5

You'll never know unless you open it. While in the military we had canned cheese that were reputed to last about 20 years.
