Where are freeze-dried foods most commonly used?
Although freeze-dried food was originally developed for use primarily by the military and astronauts, today it is used in several other areas. Thanks to the freeze-drying process, in which water is removed at low temperatures and under vacuum, freeze-dried food retains its taste, aroma, and nutritional value. This makes it a practical solution for providing energy, both in unusual field conditions and in everyday life.
Hiking and camping
Freeze-dried food is widely used in hiking and camping because it solves several key problems in the field at once: balancing weight and volume, providing a long shelf life, and making preparation easy. Compared to canned ready meals, it is much more compact and lightweight. This allows for the transport of more food without weighing down the luggage. Even after consumption, the empty packaging of the freeze-dried meal is easier to transport to a place where there is a trash can than a can, which, in addition to being bulky, has sharp edges after opening.
Preparing freeze-dried main meals is quick and easy. All you need is hot water and a few minutes to soak, and often the food is prepared directly in the heat-resistant packaging. This eliminates the need for additional dishes.
For tourists and campers, this is a reliable, practical, and energy-efficient way to provide nutritious meals, even in remote areas, in bad weather, or when the goal is the lightest, most mobile luggage possible.
Military missions
After food freeze-drying technologies began to develop in the 20th century, the military found them to be a reliable solution for ensuring adequate food reserves during missions in extreme conditions. Thus, freeze-dried products became an integral part of military MRE (Meal, Ready-to-Eat) food kits.
During reconnaissance operations, where provisions are transported on foot, by vehicle, or by air, every kilogram and every centimeter of space is extremely valuable. Freeze-dried food portions are convenient for packing into individual rations and for storage as strategic reserves.
They provide high energy value and support endurance during prolonged physical exertion, cold weather, and high altitude. For example, the varied menu we offer at ANTARTA, including freeze-dried soups, desserts, and even beverages, provides a complete set of the necessary nutrients.
Freeze-dried foods are often used as backup rations in case of supply disruptions and in missions with increased hygiene requirements, as vacuum-sealed packaging facilitates safe transport and reduces the risk of spoilage.
Scientific field expeditions
Freeze-dried food is the preferred choice during scientific field expeditions, where teams work far from modern infrastructure, often in extreme temperatures and with limited access to water. During extended research in mountains, polar regions, deserts, caves, forests, or aboard small field bases, the key criteria for food are transport efficiency, reliability, and predictability. This is where freeze-drying has a major advantage: the end product is light and compact, reducing the volume and weight of overall provisions, and its long shelf life allows for weeks of planning and the building of reserves in case of unforeseen circumstances.
Freeze-dried fruits, vegetables, and ready meals are convenient and come in appropriate portions, which allows for the rational distribution of food among team members. This also facilitates eating on the go when there are short periods of free time between different measurements, sampling, etc.
Cosmonautics
In cosmonautics, freeze-dried products are among the most reliable food solutions because they meet both the strict safety requirements and the convenience of microgravity.
When space on a spacecraft is limited, and the work schedule is planned down to the minute, freeze-dried meals offer an unmatched advantage. The food is significantly lighter and more compact, with a long shelf life and predictable quality during storage. The meals are portioned and packaged for easy use. Preparation is usually reduced to rehydration with the exact amount of water, which saves time, minimizes waste, and reduces the risk of spillage in an environment where weightlessness can be a serious problem.
The quality of the freeze-dried products we offer at ANTARTA Space Food is based on many years of scientific experience and collaboration with the Institute of Cryobiology and Food Technologies (ICFT). We develop delicious, nutritious freeze-dried food designed for missions in unusual and harsh conditions that both astronauts and ordinary mountaineers may encounter. Our freeze-dried offerings are practical, safe, and long-lasting, making them ideal for any type of expedition.
Emergency supplies
Freeze-dried meals are used by both civilians and rescue and humanitarian organizations as a reliable food reserve that can be easily used in the first critical days of an emergency.
In disasters such as power outages, floods, snowstorms, fires, earthquakes, or blocked roads, the main problems are limited access to provisions, lack of cold storage, and limited cooking time. That is why freeze-dried meals are preferred when preparing for such circumstances, as they can be stored at room temperature, take up little space, and allow for a complete meal with just the addition of hot water, and for some products, even with cold rehydration and longer soaking, which is an important advantage in the absence of electricity or a gas stove.
Food production
In the food industry, freeze-dried fruits, vegetables, herbs, coffee, and even dairy products are used in muesli, granola, protein bars, chocolate and candy, cookies, ice cream, sour milk, and desserts, as well as in soups, sauces, and ready meals.
Since freeze-dried products do not contain water, they do not dilute the taste of other ingredients or add extra moisture, making it easier to achieve the desired texture. This also reduces the risk of microbial growth and extends shelf life.
Freeze-dried raw materials can be used whole, in pieces, crushed, or as powder (for natural flavouring, colouring, and aromatising creams, glazes, fillings, and beverages), allowing precise dosing and consistency between batches.
Confectionery
The most commonly used freeze-dried forest fruits are strawberries, raspberries, and blueberries, either whole or pieces, granules, or powder. They are added to creams, ganaches, mousses, fillings, panna cotta, cheesecake, ice cream, and sorbets, as well as biscuits, cakes, and macaroons.
Because they do not contain water, they have highly concentrated flavor profiles and do not dilute the taste of chocolate, buttercreams, and glazes. They also do not disrupt their structure, which often happens when using fresh fruit or purees. This results in a better consistency, less risk of softening, and a longer shelf life for the finished product.
Freeze-dried powder is particularly convenient for naturally flavoring and coloring glazes and creams, for flavoring sugar and marshmallows, as well as for fine decorative coatings on truffles and desserts. The pieces add a desirable crunchy effect to chocolate products and granola desserts.
Conclusion
Freeze-dried food has long been used not only by astronauts; it is a practical solution that, due to its low weight, convenient packaging, long shelf life, and quick preparation, has found its place in a wide variety of fields. Whether in space travel, military and scientific missions, emergency supplies, or the food industry, freeze-drying shows how technology can make food more reliable and predictable in dynamic conditions.
