Cheese And Veggies: How Long Do They Last?

The shelf life of cheese and vegetables depends on a variety of factors, including their moisture content, storage method, and temperature. Proper storage is essential to extend the shelf life of these perishable food items and prevent food waste.

How long does cheese and vegetables last?

Fresh vegetables last longer when stored at 40°F

Fresh vegetables last longer when stored at the right temperature, humidity, and ventilation. While the recommended temperature and humidity levels depend on the type of vegetable, areas in some basements will remain cool enough (40 to 50°F) during the winter for storing many vegetables.

Root vegetables, such as potatoes, sweet potatoes, carrots, parsnips, turnips, beets, radishes, rutabagas, and yams, can be stored in a cool, dry spot in your house, like a garage, cellar, or closet, where the temperature is consistently between 40 and 50°F. At this temperature, potatoes and sweet potatoes can be kept in a paper bag for up to three months without spoiling.

Other vegetables that can be stored at 40°F include:

• Potatoes (for long-term storage)
• Cabbage
• Cauliflower
• Broccoli
• Carrots
• Peas
• Acorn squash
• Apples
• Melons
• Tomatoes

It is important to note that some vegetables, like tomatoes, will be damaged by prolonged exposure to temperatures under 50°F. Additionally, most vegetables will store longer and remain in better condition if placed in perforated polyethylene bags.

Vegetables can be frozen to be enjoyed year-round

To freeze vegetables, start by cleaning and preparing them as you normally would. This could include peeling, chopping, or slicing them into your desired shape and size. Blanching the vegetables before freezing is a crucial step to prevent enzyme actions and bacterial growth, which can affect the taste, color, and texture of the produce. Blanching also stops the loss of vitamins and helps to preserve the vegetables' appearance, flavor, and nutritional value.

After blanching, quickly cool the vegetables in ice water to stop the cooking process. Drain them well, and then spread them on a tray or plate in a single layer. Place the tray in the freezer until the vegetables are frozen solid. Finally, transfer the frozen vegetables to airtight containers or freezer bags. Label and date the containers, and store them in the freezer for up to a year.

When you're ready to use frozen vegetables, simply take them out of the freezer and cook them without thawing. Frozen vegetables are versatile and can be used in soups, stews, casseroles, stir-fries, and more. Freezing vegetables is an excellent way to reduce food waste and ensure you always have a supply of nutritious produce on hand.

Soft cheeses like ricotta, feta, and mozzarella have a shorter shelf life

Soft cheeses, such as ricotta, feta, and mozzarella, have a shorter shelf life than harder varieties. This is because they have a higher moisture content, which provides an ideal environment for bacteria to multiply and thrive, leading to spoilage. Therefore, soft cheeses are more perishable and should be consumed within a week to a few weeks of opening. Proper storage is key to extending the shelf life of soft cheeses. For instance, soft cheeses sold in brine, like feta or fresh mozzarella, should be kept in the liquid with a secure lid on the container. Soft-ripened or "semi-soft" cheeses like Brie are more delicate and should be wrapped in cheese or parchment paper and kept in an airtight container.

Fresh cheeses like ricotta and cottage cheese are highly perishable and typically last only a few weeks past their 'best by' date when stored in the refrigerator. They should be stored in their natural liquid in a plastic container.

It is important to note that the shelf life of soft cheeses can be affected by factors such as the manufacturing process, freshness, and storage conditions. Additionally, soft cheeses that have been shredded, crumbled, or sliced have a larger surface area, making them more susceptible to spoilage. Therefore, it is recommended to inspect these cheeses closely for any signs of spoilage, such as a slimy texture, a yellowed colour, mould, sourness, or a scent of ammonia. If any of these signs are present, the cheese should be discarded immediately.

Semi-hard cheeses like cheddar and Gruyère can last up to three weeks

Semi-hard cheeses, such as cheddar, Gruyère, Comté, aged Manchego, and Monterey Jack, can last up to three weeks in the fridge. This is because they contain less moisture than soft cheeses, which makes them less susceptible to bacterial growth.

To ensure your semi-hard cheese lasts for the full two to three weeks, follow these steps:

• Remove the cheese from its plastic packaging.
• Wrap it loosely in a pliable yet breathable material, such as wax paper or cheese paper.
• Put the cheese in a container with an airtight lid.

It is important to note that the shelf life of cheese can vary depending on factors such as the cheese-making process and freshness. Additionally, the quality and taste of the cheese will decline over time, even before the end of its shelf life. Therefore, it is recommended to only buy cheese for the week ahead.

When it comes to storing cheese, it is crucial to allow it to breathe and release moisture while protecting it from low humidity in the fridge. Avoid wrapping cheese in tight, non-porous material like plastic wrap, as this can dry it out and negatively impact its flavour. Instead, use porous materials like cheese or wax paper.

Hard cheeses like aged cheddar and Gouda can last up to four weeks

Hard cheeses, such as aged cheddar, aged Gouda, and Parmigiano Reggiano, can last a long time – about four weeks in the refrigerator. This is because they are low in moisture, making it difficult for bacteria to flourish. Hard cheeses are aged for longer periods and have a distinct, crumbly texture. They are made by removing most of the whey from the curds during the cheesemaking process, which removes a lot of the moisture. They are then either brined to create a hard rind or waxed and aged for between two and 36 months, or even longer.

The longer ageing process means hard cheeses usually have more complex flavours and a texture best for crumbling or grating. They have a lower moisture content, which helps extend their shelf life. Hard cheeses that haven't been opened can last for several months and even up to a year when stored in the fridge.

Once opened, a package of hard cheese can last about four weeks in the refrigerator. Unopened packages will last about six months, according to the USDA.

To store hard cheese in the refrigerator, remove the cheese from its plastic packaging and wrap it loosely in cheese paper or wax paper. Then put the cheese in a container with an airtight lid.
