Overall, both dehydrated and freeze-dried food can last a long time and it’s important to remember that the shelf life of both will depend on a variety of factors. Freeze-dried food generally has a shelf life of up to 30 years when stored properly in sealed and airtight containers. This process is the most efficient way to dehydrate food, as it removes almost all the moisture from the food, drastically reducing its weight and volume. This method also reduces the oxygen level in the air, further reducing the chances of spoilage. This process removes 99-98% of the moisture, depending on the method used.įreeze-drying is a more advanced method of dehydrating food that involves reducing the temperature to below freezing, which removes the bulk of the water from the food. Dehydration is the process of removing all the moisture from food and is done either with methods such as sun drying, oven drying and wind drying, or through the use of a mechanical dehydrator. However, it is important to note that the shelf life of both types of food depends on several factors, such as the type of food, storage method and atmosphere.ĭehydrated food typically has a shelf life of around 6-12 months, while freeze-dried food generally lasts between 2 and 30 years. Overall, dehydrated food lasts longer than freeze-dried food. What dried fruit has the longest shelf life? ![]() ![]() Pre-cooked foods are also not ideal for freeze-drying, as the process may cause the food to lose some of its flavor and texture. The fat can turn rancid during the freeze-drying process, making the dairy products unsuitable for consumption.ĥ. Dairy products, such as milk, cream and butter, do not freeze-dry well either due to their high fat content. The acidity of these foods makes them more susceptible to microbial spoilage during the freeze-drying process.Ĥ. Highly acidic foods, such as tomatoes and citrus fruits, cannot be freeze-dried either. Freezing and drying the oil can cause it to clump together, leaving the food with an undesirable texture and taste.ģ. Any food with an oil content, such as avocados, nuts and seeds, are not good candidates for freeze-drying. The process of freeze-drying causes the water molecules to crystallize and the fruit cells to shrink, making it difficult to capture the flavor and texture of these fruits.Ģ. Fruits with high water content, such as bananas, strawberries, raspberries, peaches, oranges, and grapefruits are not good candidates for freeze-drying. There are certain foods that cannot be freeze-dried:ġ.
