How Safe is Grated Parmesan Cheese from a Canister After Opening and Refrigeration?

Understanding Grated Parmesan Cheese

Grated parmesan cheese, especially in a canister like the Kraft brand, is a popular choice for many cuisines around the world. However, its proper storage and consumption can be a point of confusion, particularly regarding refrigeration and its shelf life.

Unlike fresh cheese, grated parmesan cheese can indeed last for extended periods if stored properly. It's important to understand the composition and characteristics of this cheese to ensure that it remains safe for consumption.

Storage Recommendations

The primary myth surrounding grated parmesan cheese is the recommendation against storing it in the refrigerator. This advice is rooted in the concern that moisture in the air can cause the cheese to clump together. However, with proper wrapping and storage, this issue can be mitigated.

Traditional wisdom suggests leaving the cheese on the open shelf at room temperature. However, if storing it in the refrigerator is necessary due to limited shelf space or humidity concerns, it can still be safely preserved for a long time. The key is to wrap it tightly in plastic wrap or place it in an airtight container to prevent moisture from affecting the texture.

Longevity and Safety

Grated parmesan cheese can last for years when stored properly, not necessarily requiring refrigeration unless it has been opened. The cheese is highly preserved, making it safe to eat as long as no molds or off-tastes have developed over time.

According to food safety experts, grated parmesan is safe to consume even if it has been left out for a prolonged period. This is because this cheese is crafted from hard cheese, which is naturally more resistant to spoilage. It can, however, develop off-tastes or become a bit oxidized, but it remains edible.

The Quality of Grated Parmesan Cheese

There is a significant difference between commercially produced grated parmesan cheese and high-quality, traditional parmesan cheese like Parmigiano-Reggiano. Many processed grated parmesan cheeses contain additives such as corn starch, sawdust, and cellulose, which can affect their taste and texture. These “imitation” cheeses are generally not recommended for health or culinary reasons.

For the best experience and health benefits, it is always advisable to purchase real Parmigiano-Reggiano cheese and grate it as needed. Grated fresh from a block will not only taste better but will also be free from any additives and contaminants.

Conclusion

Grated parmesan cheese from a canister is perfectly safe to eat for extended periods, provided it is stored correctly. It’s important to differentiate between the processed imitation cheese and authentic Parmesan. Opting for the genuine product will ensure both safety and superior flavor in your dishes.

Safeguard your enjoyment by storing your grated parmesan cheese properly and choosing the right product. Waste no food that is perfectly safe for consumption. Enjoy the rich, authentic taste of Parmigiano-Reggiano and other high-quality cheeses.
