Understanding Freeze Dried Food
Have you ever wondered what exactly freeze dried food is and how it differs from other types of preserved foods? Freeze drying is a unique process that involves removing moisture from food while keeping its flavor and nutritional content intact. The result is a lightweight and easy-to-store product that can be rehydrated to its original form when needed.
The process of freeze drying involves three main stages: freezing, primary drying, and secondary drying. During freezing, the food is quickly frozen to retain its structure. Primary drying involves removing the ice through sublimation, while secondary drying removes the remaining moisture through desorption.
Freeze dried food has a much longer shelf life compared to other types of preserved foods. It can last for up to 25 years when stored properly, making it an excellent option for emergency food supplies and outdoor adventures. Additionally, freeze dried food is lightweight, making it easy to carry on hiking or camping trips.
One of the most significant advantages of freeze dried food is that it retains its original flavor and nutritional content. The process of freeze drying preserves the food’s enzymes, vitamins, and minerals. As a result, freeze dried food is often considered to be healthier than canned or dehydrated food.
Freeze drying is a popular method of food preservation used by many industries, including the military, aerospace, and pharmaceutical industries. Additionally, freeze dried food is becoming increasingly popular among hikers, campers, and preppers who value its long shelf life and convenience.
What is Freeze Dried Food?
Freeze dried food is a popular food preservation technique that involves removing water from food products to extend their shelf life. The process starts by freezing the food, then removing the ice through sublimation – a process that turns solid water into vapor without going through the liquid phase. The result is a dehydrated, lightweight, and long-lasting food product that can be easily rehydrated with water when ready to eat. Freeze-drying preserves the texture, flavor, and nutrients of the food, making it a popular choice among outdoor enthusiasts, emergency preparedness enthusiasts, and space agencies.
Many types of food can be freeze-dried, including fruits, vegetables, meats, and even entire meals. The process removes 98-99% of the water content from the food, leaving it with a longer shelf life and making it lighter and easier to transport. Freeze-dried food has a significantly longer shelf life compared to other preservation methods, such as canning or dehydrating.
The benefits of freeze-dried food extend beyond just longer shelf life. Freeze-drying also preserves the nutritional content of the food. Freeze-dried fruits and vegetables retain most of their original vitamins and minerals, making them a great source of nutrients for outdoor enthusiasts, hikers, and other adventurers who need to maintain a balanced diet while on the go.
Benefits of Freeze Dried Food
When it comes to emergency preparedness or outdoor adventures, freeze dried food can be a game-changer. Here are some of the benefits of this long-lasting, lightweight, and convenient food option:
Long Shelf Life: One of the greatest advantages of freeze dried food is its long shelf life. Properly stored, this type of food can last up to 25 years, making it a great option for emergency food storage.
Lightweight: Freeze dried food is incredibly lightweight, making it an ideal option for backpacking, camping, and other outdoor activities. When you’re carrying all your gear on your back, every ounce counts, and freeze dried food can help keep your pack weight down.
Nutrition: Just because freeze dried food is lightweight and long-lasting doesn’t mean it lacks nutrition. In fact, freeze drying preserves the nutrients in the food, making it a healthy option for meals on the go.
Versatility: Freeze dried food is incredibly versatile and can be used in a variety of ways. From simple meals on the trail to emergency food storage, freeze dried food is a reliable and convenient option for any situation.
Long Shelf Life
One of the most notable benefits of freeze dried food is its long shelf life. Because freeze drying removes almost all water from the food, it becomes inhospitable to bacteria, yeast, and other microorganisms that cause spoilage. As a result, freeze dried food can last up to 25 years or more when stored properly.
Long shelf life is particularly advantageous for preppers and outdoor enthusiasts who want to have a supply of food that can withstand the test of time and be readily available when needed. It also saves money in the long run, as you won’t have to replace food as frequently due to spoilage.
Another benefit of the long shelf life of freeze dried food is that it allows for easy and convenient food storage. You can store freeze dried food in your pantry, basement, or other dry areas of your home without worrying about spoilage or degradation.
One of the major benefits of freeze-dried food is that it retains its nutritional value. The freeze-drying process removes the water content of the food, which can sometimes lead to the loss of nutrients. However, since the process involves freezing the food and then placing it in a vacuum, the food maintains its nutritional content.
Studies have shown that freeze-dried fruits and vegetables, for example, can contain up to 97% of their original nutritional value. This is due to the fact that the process does not involve high heat, which can break down vitamins and minerals in the food.
In addition, freeze-dried foods often contain no added preservatives, making them a healthier option than many canned or packaged foods. They are a great way to maintain a healthy diet even in emergency situations, when fresh food is not readily available.
Freeze dried food is not only nutritious, but also incredibly convenient for those who lead busy lives or enjoy outdoor activities. One of the most significant benefits of freeze dried food is its lightweight nature, making it easy to pack for camping trips, backpacking, or even emergency situations.
Another benefit of freeze dried food is its long shelf life, which can range from 25 to 30 years for some products. This makes it an excellent option for preppers, hikers, and those who want to stock up on food for emergencies.
Freeze drying also retains the original taste and flavor of the food, unlike other food preservation methods that can alter the taste or texture. The freeze drying process removes water content while preserving the nutrients and taste, resulting in food that tastes fresh when rehydrated.
Since freeze dried food is already cooked and only requires rehydration, it is convenient for those who want a quick meal without the hassle of cooking. Freeze dried food can also be used as a healthy snack option or added to recipes for an extra nutritional boost.
Preparing Freeze Dried Food for Short-term Storage

Store in a Cool and Dry Place
Proper storage is essential for maintaining the quality of freeze dried food. After choosing the right packaging, it’s important to store the food in a cool and dry place.
Cool: Freeze dried food should be stored at a temperature between 50 and 70 degrees Fahrenheit. Avoid storing in areas that experience temperature fluctuations, such as near windows or heating vents.
Dry: Moisture can cause freeze dried food to spoil. Store in a dry place, away from humidity and moisture sources like basements, bathrooms, and kitchens. Consider using a dehumidifier if the storage area is prone to humidity.
Dark: Exposure to light can cause freeze dried food to degrade over time. Store in a dark area, such as a pantry or closet.
Preparing Freeze Dried Food for Long-term Storage
Choose the Right Container: When preparing freeze dried food for long-term storage, it’s important to choose the right container. Opt for containers that are air-tight, moisture-proof, and made of a durable material such as metal or plastic.
Label and Date: To keep track of your food storage, it’s important to label and date all containers. This will help you easily identify the contents and keep track of when the food was stored.
Store in a Cool and Dry Place: When it comes to long-term storage, the temperature and humidity of the storage location can have a big impact on the quality of your food. Store your containers in a cool, dry, and dark location to help preserve their freshness.
Check and Rotate: It’s important to periodically check your stored freeze dried food to ensure that it’s still fresh and edible. Rotate your food storage by using the oldest containers first and replacing them with fresh ones.
Use Oxygen Absorbers
Oxygen absorbers are small packets that contain iron powder and are used to remove oxygen from the sealed container of freeze-dried food. Oxygen is the primary cause of food spoilage, so removing it can greatly increase the shelf life of the food.
Make sure to use the right number of absorbers for the size of your container. A general rule is to use one 300cc absorber for every one-gallon container.
Handle oxygen absorbers carefully with clean, dry hands or tools, as they can be activated by moisture or oil. If they become activated before use, they won’t work to remove oxygen from the container.
Seal the container quickly after placing the oxygen absorber inside. The absorber will start removing oxygen immediately, so it’s important to seal the container as soon as possible to prevent additional air from entering.
Consider Mylar Bags or Food-Grade Buckets
If you’re storing freeze dried food for the long-term, it’s important to use proper containers that will keep the food fresh and prevent it from spoiling. Two great options are Mylar bags and food-grade buckets. Both options provide an airtight seal and protect the food from moisture, oxygen, and pests.
Mylar bags are a popular choice because they are lightweight, easy to store, and come in a variety of sizes. They are made from a polyester film that is laminated to aluminum foil, which provides an effective barrier against moisture and oxygen.
Food-grade buckets are another great option for long-term storage. They are made from a heavy-duty plastic that is designed to withstand extreme temperatures and resist punctures and cracks. Many food-grade buckets also come with airtight lids that provide an extra layer of protection against moisture and pests.
Whether you choose Mylar bags or food-grade buckets, be sure to label them clearly with the contents and the date of storage. This will make it easy to keep track of your food inventory and ensure that you use the oldest items first.
Rehydrating Freeze Dried Food: Dos and Don’ts
When it comes to rehydrating freeze dried food, there are certain dos and don’ts to keep in mind. Following these guidelines will help ensure that your food is properly rehydrated and retains its nutritional value:
Do: Follow the instructions on the package for the correct amount of water to use.
Do: Let the food sit for the recommended amount of time to fully rehydrate.
Don’t: Use hot water to rehydrate the food, as this can break down important nutrients.
Don’t: Over-rehydrate the food, as this can cause it to become mushy and lose its texture.Rehydrating freeze dried food is a simple process, but it’s important to follow these guidelines to ensure that your food is properly rehydrated and ready to eat.
Follow Instructions Carefully
Rehydrating freeze dried food is easy, but it’s important to follow the instructions carefully to get the best results. Each type of food may have different instructions, so make sure to read them carefully before starting.
Water to Food Ratio: One of the most important things to pay attention to is the water to food ratio. Adding too much or too little water can result in a meal that is either too watery or too dry. Always use the recommended amount of water for the particular food you are rehydrating.
Temperature of Water: Another factor to consider is the temperature of the water. Most instructions will recommend using hot or boiling water, but some foods may require cold water. Using the wrong temperature can also result in a meal that is not rehydrated properly.
Rest Time: After adding water to the freeze dried food, it’s important to let it rest for the recommended time to allow the food to fully absorb the water. Not letting it rest enough can result in unevenly rehydrated food.
Avoid Over-soaking the Food
When rehydrating freeze dried food, it’s important to remember that less is often more. While it can be tempting to soak the food for longer in order to ensure that it’s fully rehydrated, doing so can actually lead to a mushy, unappetizing result. Follow the instructions on the package carefully, and err on the side of caution if you’re unsure.
It’s also important to use the right amount of water. Too much water can lead to the same mushy result as over-soaking, while too little water can leave the food tough and chewy.
Finally, don’t be afraid to experiment with different rehydration methods. Some foods may benefit from a shorter soak time or a slightly different water-to-food ratio than what’s recommended on the package. Just remember to take notes so you can reproduce your successes in the future.
