Fresh mozzarella can last up to a week past its expiration date if unopened and stored correctly
Fresh mozzarella is a high-moisture cheese, which means that it can spoil faster than other cheeses if not stored properly. However, if unopened and stored correctly, it can last up to a week past its expiration date.
To ensure that your fresh mozzarella lasts as long as possible, it is important to follow some storage guidelines. Firstly, keep the cheese sealed in its original packaging until you are ready to use it. This helps to maintain its moisture and prevents contamination. It is also important to store the cheese in the coldest part of your refrigerator, usually the back, where the temperature is more stable.
In addition to consistent temperature, avoid cross-contamination by keeping mozzarella away from foods with strong odors or potential contaminants. This will prevent any transfer of flavors or bacteria. Always be mindful of the expiration date and aim to consume the cheese before this date for optimal freshness.
Even if your mozzarella is unopened, it is a good idea to periodically check it for any signs of spoilage, such as mold or an off smell. Spoiled mozzarella can pose health risks, so it is important to be aware of these signs. Some indicators of spoilage include mold growth, discoloration, texture changes, an off smell, and a slimy texture.

Properly storing mozzarella is crucial to maintaining its quality and extending its shelf life. Low-moisture mozzarella can last for several weeks in the fridge, depending on the packaging and storage conditions.
Firstly, it is important to store mozzarella in its original packaging until you are ready to use it. This helps to maintain its moisture and prevents contamination. If you have bought mozzarella in a vacuum-sealed package, it can be kept in the fridge unopened until you need it.
Secondly, the cheese should be stored in the coldest part of the refrigerator, typically the back, where the temperature is more stable. It is also important to store mozzarella away from foods with strong odours or potential contaminants to prevent any transfer of flavours or bacteria.
Thirdly, always be mindful of the expiration date and consume the cheese before this date for optimal freshness. It is recommended to check the cheese periodically for any signs of spoilage, even if it is unopened. Spoiled mozzarella can pose health risks, so it is important to be aware of the signs of spoilage. These include mould growth, discoloration, texture changes, and an off smell or slimy texture.

Signs of spoilage include mold, discolouration, and changes in texture, smell, and taste
When it comes to determining whether unopened mozzarella cheese has gone bad, careful observation is required. Spoiled mozzarella can pose health risks, so it's crucial to be vigilant for any signs of spoilage.
In addition to visual cues, off-smells and changes in taste can indicate spoilage. A sour, rancid, or otherwise unpleasant odour may suggest that the cheese has gone bad. Fresh mozzarella should have a mild, milky aroma, while low-moisture mozzarella has a milder, more pleasant smell. If the cheese smells or tastes odd, it's best to discard it.
Proper storage is essential to maintaining the quality and extending the shelf life of unopened mozzarella cheese. It should be stored in its original packaging in the coldest part of the refrigerator to maintain a consistent temperature. Keeping mozzarella away from foods with strong odours or potential contaminants helps prevent flavour transfer or bacterial growth. Regularly inspecting the cheese for any signs of spoilage, even if it is unopened, is also recommended.

Freezing mozzarella can extend its shelf life, but it may lose its creamy texture
Mozzarella is a soft cheese with a high moisture content, which means it can spoil faster than other cheeses if not stored properly. Proper temperature control and packaging are key to preserving this delicate cheese. It should be stored in the refrigerator at temperatures between 34°F and 40°F (1-4°C). This temperature range slows bacterial growth and helps maintain the cheese's texture and flavour. Fresh mozzarella can be kept in its original brine solution to preserve moisture.
Frozen mozzarella is best used in cooked dishes rather than fresh applications, as its texture may become crumbly and dry or grainy. It can be used in baked pasta dishes such as lasagna, gnocchi Sorrentina, and baked ziti. It is important to note that mozzarella should not be frozen if a fresher alternative is available for salads or sandwiches, as the freezing process affects the texture of the cheese.
Fresh mozzarella will typically last up to a week past its expiration date if stored correctly in the fridge. Low-moisture mozzarella can last for several weeks in the fridge, depending on the packaging and storage conditions. Once opened, fresh mozzarella will only last 3-5 days in the fridge before showing signs of spoilage, such as a sour smell, slimy texture, or mold growth. Therefore, freezing can be a useful option to extend the shelf life of mozzarella, despite the potential change in texture.
