Why Some Canned Foods Have an Indefinite Shelf Life
Certain foods have properties that enable them to last indefinitely. Factors like low moisture content, high salt or sugar concentration, and the absence of fats or oils (which can go rancid over time) play a critical role in preserving these foods. While their flavor or texture may change over the years, they remain completely safe to consume.
Factors That Contribute to Canned Food Longevity
Airtight Sealing: Prevents air and moisture from entering, which could cause spoilage.
Sterilization Process: The canning process heats food to destroy bacteria, yeasts, and molds.
Preservative Properties: High salt or sugar levels, acidity, or preservatives help prevent spoilage.
