How to properly store Parmesan cheese?
After opening a wedge or block of Parmesan cheese, it is best to wrap it tightly in aluminum foil or plastic wrap. This will help prevent moisture from entering and air from oxidizing the cheese. Place the wrapped cheese in a resealable plastic bag or an airtight container to provide an extra layer of protection.
Remember to keep Parmesan cheese away from strong-smelling foods, as it can absorb odors easily. It is also advisable to label the cheese with the date of opening to keep track of its freshness.
How long does Parmesan cheese last in the refrigerator?
When stored properly in the refrigerator at a temperature between 35°F (1.7°C) and 40°F (4.4°C), Parmesan cheese can last up to six months after opening. However, the cheese may start to lose its flavor and texture over time, so it is best to consume it within the first three to four months.
In conclusion, refrigeration is necessary to maintain the quality and freshness of Parmesan cheese. By keeping it properly stored, you can extend its shelf life and enjoy the full flavor of this delicious cheese.
Unopened Parmesan Cheese
When it comes to unopened Parmesan cheese, it is generally safe to store it at room temperature. This is thanks to the low moisture content and aging process of Parmesan, which helps to inhibit the growth of bacteria.
However, it is important to keep the cheese in a cool, dry place away from direct sunlight. A pantry or cupboard is a suitable location for storing unopened Parmesan cheese.
Proper storage will help to maintain the quality and flavor of the cheese for a longer period of time. It is recommended to check the expiration date on the packaging and consume the cheese before that date for optimal taste.
Once the cheese is opened, it is advisable to transfer it to a resealable bag or airtight container and refrigerate it. This will help to prolong the shelf life of the cheese and maintain its freshness.
Remember, always use your senses to determine if the Parmesan cheese is still safe to eat. If it develops an off smell, mold, or an unusual texture, it is best to discard it to avoid the risk of foodborne illness.
Opened Parmesan Cheese
