Is Freeze-Dried Food Good for Survival? The Pros and Cons You Need to Know

Freeze-dried food is widely recognized as a reliable option for survival due to its long shelf life and nutrient retention. Through the freeze-drying process, the majority of the food's moisture is removed, which not only preserves its original flavor and texture but also allows it to be stored for up to 25 to 30 years without degradation. Additionally, when rehydrated, freeze-dried foods revert closely to their original state, making them both nutritious and palatable. Given these attributes, such foods have become staples in emergency preparedness kits and are favored by survivalists and outdoor enthusiasts alike.

    What is Freeze-Drying?

    Freeze-drying, also known as lyophilization, is a food preservation method that involves removing moisture from food by sublimation. Sublimation is the process of changing a solid directly into a gas without going through the liquid phase. Freeze-drying is a complex process that involves several stages, including freezing, primary drying, and secondary drying.

    During the freezing stage, the food is rapidly frozen at very low temperatures to preserve its structure. The frozen food is then placed in a vacuum chamber where the pressure is lowered, and heat is applied to cause the ice in the food to sublimate. This process removes the moisture from the food, leaving it dry and lightweight.

    Freeze-drying is a popular method of food preservation because it allows for long-term storage without the need for refrigeration. Freeze-dried foods can last for years when stored in a cool, dry place. This makes it an ideal method for preserving food for survival situations or for people who enjoy outdoor activities like camping and hiking.

    Benefits of Freeze-Dried Food for Survival

    When it comes to survival situations, freeze-dried food can be a life-saver. Here are some of the benefits of freeze-dried food for survival:

    Long Shelf Life

    One of the most significant advantages of freeze-dried food for survival is its long shelf life. Freeze-dried food can last for 25+ years without losing quality or nutritional value. Freezing inhibits chemical and microbiological processes that cause food spoilage, and freeze-dried food does not need power or temperature control to keep. For example, NASA uses freeze-dried food for space missions because it can withstand extreme conditions and remain safe to eat.

    Lightweight and Portable

    Freeze-dried food is about 80% lighter than fresh food because the water content is removed. This makes it easier to transport, store, and carry in backpacks or bug-out bags. For example, a 72-hour survival kit from Food Bunker weighs only 1.5 kg and contains 18 meals.

    Ease of Preparation and Variety

    Another benefit of freeze-dried food for survival is its ease of preparation and variety. Freeze-dried food only requires adding water to rehydrate and cook, which saves time, fuel, and water resources in survival situations. Freeze-dried food can retain the original texture, shape, flavor, and color of the food. There is a wide range of freeze-dried foods available, from fruits and vegetables to meats and dairy products. For example, you can cook your family’s favorite meals with freeze-dried ingredients, such as lasagna, chicken curry, or beef stew.

    Overall, freeze-dried food is an excellent option for survival situations due to its long shelf life, lightweight and portable nature, and ease of preparation and variety. Whether you are preparing for a natural disaster or a camping trip, freeze-dried food can help you stay nourished and energized when fresh food is not an option.

    Drawbacks of Freeze-Dried Food for Survival

    While freeze-dried food has many benefits for survival situations, it also has some drawbacks to consider.

    Cost and Availability

    Freeze-drying is an expensive and complex process that requires specialized equipment and expertise. As a result, freeze-dried food is usually more expensive than other types of preserved food, such as canned or dehydrated food. During times of high demand or crisis, freeze-dried food may also be hard to find or out of stock. For example, during the COVID-19 pandemic, many survival food companies sold out of freeze-dried food and had long waiting times for orders.

    Nutritional Value and Taste

    Freeze-drying may also alter the taste or texture of some foods, especially if they are not properly rehydrated or stored. Some freeze-dried foods may contain additives, preservatives, or high amounts of sodium or sugar to enhance their flavor or shelf life. As a result, some people may find freeze-dried food bland, dry, or mushy compared to fresh food.

    It's important to note that freeze-dried food may also lose some of its nutritional value during the freeze-drying process. While freeze-dried food can still provide essential nutrients, it may not be as nutrient-dense as fresh food.

    Comparing Freeze-Dried Foods to Other Survival Food Options

    When it comes to survival food options, there are several choices available. Freeze-dried foods are a popular option, but how do they compare to other options like canned goods, MREs, and bulk staples?

    MREs (Meals, Ready-to-Eat)

    MREs are a convenient option for survival food. They come in a compact package that is easy to carry and can be eaten without any preparation. However, they tend to be heavy and bulky, making them less ideal for long-term survival situations where weight is a concern.

    In comparison, freeze-dried foods are lightweight and take up less space, making them a better option for long-term storage. Additionally, freeze-dried foods tend to have a longer shelf life than MREs.

    Canned Foods

    Canned goods are a popular choice for survival food because they are easy to find and can be stored for a long time. However, they tend to be heavy and take up a lot of space, making them less ideal for situations where weight and space are a concern.

    Freeze-dried foods, on the other hand, are lightweight and compact, making them a better option for long-term storage and situations where space is limited. Additionally, freeze-dried foods tend to retain more nutrients than canned goods.

    Bulk Staples

    Bulk staples like grains and beans are a popular choice for survival food because they are affordable and have a long shelf life. However, they require preparation and cooking, which can be difficult in a survival situation.

    In comparison, freeze-dried foods are easy to prepare and can be eaten right out of the package. They also have a long shelf life and are lightweight, making them a great option for long-term storage.

    Overall, freeze-dried foods are a great option for survival food because they are lightweight, have a long shelf life, and are easy to prepare. While other options like MREs, canned goods, and bulk staples have their advantages, freeze-dried foods are a versatile and practical choice for long-term survival situations.

    Incorporating Freeze-Dried Foods into a Comprehensive Survival Plan

    When it comes to emergency preparedness, freeze-dried food can be an excellent addition to your survival kit. With a shelf life of 25+ years, it's lightweight, portable, and easy to cook, making it a great investment for future preparedness. Here are some tips on how to incorporate freeze-dried food into a comprehensive survival plan.

    Planning a Balanced Diet

    It's essential to make sure that you're covering all of your nutritional needs when planning your survival kit. Freeze-dried food can provide a good source of protein, fiber, and other essential nutrients. However, it's essential to pair it with other foods to ensure that you're getting a balanced diet. Consider adding canned fruits and vegetables, nuts, and seeds to your survival kit to provide additional nutrients.
