Storing Cheese Powder: Long-Term Preservation Techniques

Cheese is a versatile ingredient that can be used to turn bland storage food into delicious meals. It can be stored as fresh, freeze-dried, or dehydrated. Each type has advantages, and all of them contribute to a varied menu.

Fresh cheese can be stored for three to six months if it is in its original packaging and kept cool in the refrigerator. Generally, the harder the cheese, the longer it will keep. It is possible to store hard brick cheese for several years if it is tightly wrapped in heavy plastic or foil to exclude air.

Freeze-dried cheese is widely available as cheddar, Colby, Monterey Jack, and mozzarella. It is best used as an ingredient in recipes and can be reconstituted or used as is. It makes four times its original weight when reconstituted.

Powdered or dehydrated cheese is a product made with whey, starches, cheese flavourings, and assorted food additives. It is versatile and can be reconstituted with water or oil or used directly in casseroles, soups, sauces, dips, and baked goods. The shelf life for powdered cheese is three to five years, and it keeps for about four months after opening.

There are several options to consider when it comes to storing cheese powder long-term, including nutritional content, quality, and shelf life.

Freeze-dried cheese can last up to 25 years

Freeze-dried cheese is an excellent option for long-term storage. The process of freeze-drying removes all moisture from the cheese, inhibiting microbial development and deterioration. This extends the shelf life of the cheese, with some sources claiming that it can last up to 25 years when packaged and stored appropriately.

To achieve this impressive longevity, several factors must be considered. Firstly, the cheese should be packaged in air-tight containers, such as vacuum-sealed bags or mason jars. Oxygen absorbers can also be included to prolong the cheese's shelf life further. Additionally, it is crucial to store the cheese in a cool, dark, and dry place, as high temperatures can cause the fats in the cheese to turn rancid, affecting its taste.

When stored under optimal conditions, freeze-dried cheese can maintain its quality and flavour for up to two decades, making it a valuable food item for emergency preparedness, trekking, and even space missions.

It is worth noting that freeze-dried cheese is not limited to a specific type of cheese. Various cheeses, such as Parmesan, Romano, Cheddar, Gouda, and Swiss, are suitable for the freeze-drying process due to their low moisture content. Even soft cheeses like cream cheese and blue cheese can be freeze-dried, although they require more careful handling and energy during the process.

In addition to its longevity, freeze-dried cheese offers several advantages. The process maintains the cheese's nutrients, preserving approximately 90% of its vitamins and minerals. It also reduces weight by up to 90%, making it easier for storage and transportation. Moreover, freeze-dried cheese is easy to rehydrate, almost completely recovering its original culinary quality.

Dehydrated cheese has a shelf life of 3-5 years

Dehydrated cheese is a product made with whey, starches, cheese flavourings, and food additives. It is available in a variety of types, including Parmesan, cheddar, Swiss, and blended cheese. Less common varieties, such as asiago, blue, feta, Romano, and provolone, can also be found on specialty food websites.

Dehydrated cheese is a great option for those looking to add variety to their food storage. It can be purchased in bulk, and its long shelf life makes it a cost-effective option. It is also a good choice for those who want to avoid the expense and hassle of freeze-drying their own cheese.

When storing dehydrated cheese long-term, it is important to keep it in a cool, dry location. It should be stored in an airtight container, such as a Mylar bag or metal can, with oxygen absorbers. This will help to prolong its shelf life and maintain its quality.

Dehydrated cheese is a valuable addition to any food storage plan, offering versatility and a long shelf life. With proper storage, it can last for 3-5 years, providing a tasty and nutritious option for those preparing for emergencies or simply looking to stock their pantry.

Fresh cheese can be stored for 3-6 months

Firstly, it is important to note that the length of time you can keep cheese differs depending on the variety; in general, harder cheeses will last longer. Fresh cheese has the shortest shelf life. For context, hard cheeses can last up to three to four weeks, and semi-hard cheeses should be consumed within 7-10 days.

Fresh cheese should be stored in its original packaging and the water should be changed every couple of days. It should be stored in the refrigerator, in the vegetable crisper, where the temperature is cold and stable. It will last between 7 to 10 days in the fridge.

To store fresh cheese long-term, you can also vacuum seal the cheese and store it in a place that is cool, dark, and dry. This method can make the cheese last for a few years.

To maximise the lifespan of fresh cheese, only slice the cheese as needed, as slicing increases its surface area, exposing more cheese to possible contamination, oxidation, and dehydration, thus shortening its shelf life.

Cheese waxing is a popular preservation method

Step 1: Purchase Your Cheese Wax

First, you'll need to get your hands on some food-grade cheese wax, which is typically made from a combination of paraffin and microcrystalline. You can choose from a variety of colours, including white, red, yellow, blue, and green, each paired with different types of cheese. For example, white wax is used for mild and semi-soft cheeses like gouda and cheddar, while red wax is used for harder, more pungent cheeses like Parmesan and Gruyère.

Step 2: Prepare Your Cheese for Waxing

Before waxing, you must clean the surface of your cheese. You can use either a vinegar wash (a mixture of vinegar, water, and salt) or a brine wash (a mixture of salt and water). These solutions will remove any bacteria or dirt from the cheese surface and keep it clean and bacteria-free before waxing.

Step 3: Start Waxing Your Cheese

Low Heat Instructions for Waxing Soft Cheese

For soft cheeses like Brie and Camembert, you'll use the low heat method. Set up a double boiler on the stovetop and melt the wax at a low temperature. Keep the flame on its lowest setting and continuously stir the wax until it liquefies. Use a thermometer to ensure the temperature stays between 100-120°F (38-49°C). You can then use a cheesecloth or brush to coat the cheese with wax, or you can dip the cheese directly into the wax. Make sure to cover the entire surface of the cheese. Allow the first layer of wax to cool and set for about 10 minutes, then apply a second layer. You may need to repeat this process for a thorough coating. Once both sides are covered, let the wax cool completely before handling.

High Heat Instructions for Waxing Hard Cheese

For hard cheeses like cheddar, parmesan, or gouda, you'll use the high heat method. Again, set up a double boiler on the stovetop, but this time, gradually increase the temperature while stirring the wax. Use a thermometer to ensure the temperature stays between 140-180°F (60-82°C). As with the low heat method, use a cheesecloth, brush, or direct dipping to coat the cheese with wax. Make sure to cover the entire surface. Allow the first layer of wax to cool and set, then apply a second layer. Repeat if necessary. Once both sides are covered, let the wax cool completely before handling.

Storing Your Waxed Cheese

Store your waxed cheese in a cool, dry place away from sunlight and strong odours. While refrigeration is not necessary, you can wrap the cheese in wax paper or plastic wrap to protect it from drying out. With proper waxing and storage, your cheese can last for several months to a few years.

Powdered cheese is versatile and can be used in casseroles, soups, sauces, dips and baked goods

Powdered cheese is a versatile ingredient that can be used in a variety of dishes. While it may not taste exactly like real cheese, it can still add a cheesy flavour to your meals. It is commonly used in snack foods, such as being sprinkled on popcorn at theatres, and is an ingredient in Doritos.

Powdered cheese can be used in casseroles, soups, sauces, dips, and baked goods. For example, you can make a cheese sauce to use in casseroles or with pasta and vegetables. You can also sprinkle it on popcorn or baked potatoes.

Instant Homemade Mac and Cheese

• Cook 1 pound of short pasta (macaroni, penne, or fusilli) in salted water in a large pasta pot, stirring occasionally, until just al dente.
• Meanwhile, whisk together 1 1/4 cup whole milk or reconstituted powdered milk with 1 cup of cheddar cheese powder or a combination of cheese powders. (If using powdered milk, whisk it with the cheese powder first, then add water.)
• Drain the pasta and return it to the pot. Stir in 1 stick of butter, cut into pieces, until the pasta is well coated.
• Add in the milk and cheese powder mixture and cook, stirring, until the pasta is well coated and the sauce begins to thicken (about three to five minutes).
• Add salt to taste. (Note: Some powdered cheese is already salty, so be sure to taste first.)

Powdered cheese is a great option for long-term food storage. It has a shelf life of three to five years and keeps for about four months after opening. It is important to store it in a cool, dry location to prolong its shelf life.
