If you’ve noticed green or fuzzy spots on the top part of your cheese block, that’s mold! By monitoring moisture levels and using wrapping paper to control moisture, you can personally ensure that your cheese remains fresh and mold-free.
So let’s explore how you can maintain fresh and safe cheese without any unwanted surprises.
Why Does Cheese Mold in the Fridge?
Cheese is a beloved food that adds flavor and richness to many dishes. However, if not stored at the right temperature, it can quickly turn from a tasty treat to a moldy mess. But why does cheese mold in the fridge? Let’s explore the reasons behind this phenomenon at the edge of the block.
1. The Cool Temperature and High Humidity of Refrigerators
Refrigerators are designed to keep our food fresh by maintaining cool temperatures and high humidity levels. While these conditions are ideal for preserving most foods, they also create an environment conducive to mold growth on cheese.
Molds are fungi that thrive in damp environments, making the temperature and moist atmosphere inside refrigerators an inviting breeding ground for them. When exposed to these temperature conditions, mold spores present in the air can settle on the surface of cheese and begin growing rapidly.
2. Air Circulation within the Fridge
Another factor contributing to cheese molding in the fridge is temperature. If cheeses are not properly stored or covered, mold spores can easily spread from one piece of cheese to another due to inadequate air circulation. This means that even if you have one piece of moldy cheese among several others, there’s a risk of contaminating them all.
To prevent cross-contamination and minimize the chances of molds spreading, it’s essential to store cheeses separately or tightly wrap them in plastic or wax paper before placing them in the refrigerator. This helps maintain the temperature and prevents the molds from affecting other cheeses.
3. Moisture Content and Surface Characteristics
Not all cheeses are created equal. Some varieties have higher moisture content and more favorable surface characteristics for molds to grow on. Soft cheeses like brie or camembert, with their creamy textures and bloomy rinds, provide an ideal environment for molds.
On the other hand, hard cheeses such as cheddar or Parmesan have lower moisture content and denser textures that make it harder for molds to take hold. However, it’s important to note that even hard cheeses can still mold if not stored properly or exposed to excessive moisture.
4. Improper Packaging and Exposure to Moisture
The way cheese is packaged and handled also plays a significant role in its susceptibility to mold growth. If cheese is not adequately sealed or wrapped, it can be exposed to moisture in the fridge, which accelerates mold development.
To prevent this, it’s crucial to store cheese in airtight containers or wrap them tightly with plastic wrap or wax paper. This helps create a barrier against moisture and keeps the cheese fresh for longer.
5. Contamination
If mold spores come into contact with the cheese during production, handling, or storage, they can start growing and cause the cheese to mold before its expiration date.
6. Inadequate Storage Conditions:
Incorrect storage conditions, such as fluctuating temperatures or high humidity levels, can accelerate mold growth on cheese, leading to spoilage before the expiration date.
How To Prevent Cheese Mold in the Refrigerator
To keep your cheese fresh and mold-free, it’s important to take some preventive measures when storing it in the refrigerator. Here are some tips to help you prevent cheese from developing mold:
