Safety Warnings and Risks
Parmesan cheese is a low moisture cheese with low water activity, which inhibits the growth of harmful bacteria. However, there is still a risk of contamination if not stored properly. To reduce the risk of foodborne illness, always store Parmesan cheese in the refrigerator at temperatures below 40°F (4°C). Avoid keeping it at room temperature for extended periods as this can promote bacterial growth. Additionally, make sure to handle Parmesan cheese with clean hands and utensils to prevent cross-contamination.
Expiration vs Best Quality
The expiration date on Parmesan cheese indicates the date up to which the cheese is expected to remain at its peak quality. After this date, the flavor and texture may deteriorate, but it does not necessarily mean the cheese is unsafe to eat. Best quality refers to the period during which the cheese is expected to taste its best, but it can still be consumed after this date if properly stored and shows no signs of spoilage. As a hard cheese, Parmesan can last beyond its expiration date if stored correctly.
Fun Facts & Cultural Insights
Parmesan cheese, also known as Parmigiano-Reggiano, is a famous Italian cheese that has been produced for over 900 years. It is traditionally made from unpasteurized cow's milk and aged for a minimum of 12 months, with some varieties aged for up to 36 months or more. True Parmigiano-Reggiano can only be produced in certain regions of Italy and must adhere to strict production standards. It is a staple in Italian cuisine, used in dishes like pasta, risotto, and salads.
Storage Hacks & Pro Tips
To maintain the quality of Parmesan cheese, it is best to store it in airtight packaging or a resealable plastic bag to prevent moisture loss and absorption of other odors. You can also wrap it in parchment paper followed by aluminum foil for additional protection. If the cheese develops mold on the surface, you can cut off the affected part and continue using the rest. For optimal flavor, consider grating Parmesan cheese fresh as needed rather than pre-grating it and storing it for an extended period.
