∙ 14y agoIt invented itself. At a very basic level, dehydration requires sun and wind. Thus, food dehydrators, which incorporated natural elements, go back thousands of years to hunter gatherer societies. Evidence of dried fruit, grains and vegetables have also been found in ancient Mesopotamia societies. The first man made dehydrators are traced back to the 1800's and 1900's.

Freeze Drying Food For a Camping Trip?
Camping in the great outdoors can be a great way to escape from the frantic, hurried pace of everyday life. However, preparing food in a camper can be a challenge for many people. Some RV designs, like Scamp campers, have limited storage space for frozen or refrigerated food. Fortunately, freeze dried food can be a great alternative to perishable foods when on a camping trip. The following guide provides simple tips and tricks on how to freeze dry food for a camping trip. It's possible to freeze dry any type of food. This includes pizza, hot dogs, hamburgers, fruit, pineapples, soup, salad and more. While the texture on food can change significantly when it is freeze dried, the food will usually not lose its taste or nutritional content. To freeze dry food, one must invest in a freeze drying unit. These are often available for a good price from high volume discount stores. In addition, it's possible to obtain freeze dry units on the Internet from various retailers. When preparing a food for freeze drying, simply cook and prep it as usual. For hamburgers, it's even possible to add desired toppings to the dish. However, it's important to understand how freeze drying times can be impacted by the amount of water in a food product. Food products with very high water content will take longer to freeze dry than food products with a low water content. After food has been freeze dried, it's important to put it into vacuum-sealed bags. Some freeze drying machines can do this automatically for a person. This can make it very convenient to prepare food for freeze drying. It's also important to use dark colored freeze dry bags if possible. Since light can have a negative impact on food quality, it's usually a good idea to use bags that will mask light. To eat freeze dried food, simply add water and heat. In most cases, food will lose a lot of its texture during the freeze drying process. However, foods will usually retain their original taste and nutritional profile.

Who invented freeze dried foods?
Freeze dried food was actually invented by the Incas. As I understand it, they would harvest potatoes and take them to the mountaintops (as the colder temperatures and drier winds prevailed) and as each layer of the potato froze, they would peel off that thin layer as the moisture sublimated from that thin layer, that part of the potato was dry and thus preserved. Don't believe me, though.
Where do you keep freeze dried food?
Personally, I keep freeze dried food on a wire shelving unit in my air-conditioned basement. The area is clean and dry, free of moisture and pests. The freeze dried meals are in sealed #10 cans and should have a shelf life of at least 25 years while unopened. Once I have opened a container of freeze dried food, I seal it in the can with a plastic lid or in another food storage container and keep it in a kitchen cabinet or a pantry shelf to be used within a few months to a year. Always keep freeze dried food in a clean, dry, cool location and check regularly for signs of moisture or pests in your food storage area.
