Do I Have to Refrigerate Pepperoni?
Understanding Preservation Needs
Pepperoni, as a cured meat, has properties that initially allow it to be stored without refrigeration. The preservation is achieved through air-drying, a process which includes adding nitrates and salt, contributing to its shelf stability. Typically, unopened pepperoni can be kept at room temperature, and the packaging often indicates this by the absence of a "Keep refrigerated" label.
Once opened, however, pepperoni's storage requirements change to ensure safety and maintain quality. It should be refrigerated after opening to extend its lifespan and prevent spoilage. In the refrigerator, opened pepperoni can remain fit for consumption for up to three weeks. Observing good storage practices such as keeping it in an airtight container can also help maintain its condition during this time.
For those looking to preserve pepperoni for an even longer period, freezing is a viable option. Frozen pepperoni can maintain its best quality for one to two months. Should a recipe call for pepperoni, thawing it overnight in the refrigerator is recommended before use. Cautious to not refreeze previously thawed pepperoni is important as it can adversely affect the meat's texture and flavor.
