Freeze dried fruit vs dehydrated8/30/2023 ![]() Even healthy young men and women were getting side-lined by debilitating cases of constipation while eating a steady diet of c-rations and MREs while fighting fire. When eating a steady diet of dehydrated and freeze-dried food, eat a handful of dehydrated fruit each day and drink lots of fluid with it in order to prevent constipation. Learn from my mistake and rodent-proof your stash. I did not do this one time to a personal cache of leftover freeze-dried food and it was raided by mice within a month. In the Park Service and Forest Service, we used to store sealed food caches within galvanized steel garbage cans with tight-sealed lids tied or bungied into place. Place your freeze-dried foods and dehydrated goods within a mouse/rodent proof container. Read our current articles on Modern Survival Blog But now I’m getting side tracked and off topic…Īppreciate topics of survival, emergency preparedness – or planning for disaster? It’s hard to transport, requires sturdy containment, and it takes up space. It gets more difficult though when you consider long term. It’s not hard to store enough for a month. The thing is, if you don’t live near a source of fresh water (other than municipal sources), you MUST factor in the amount of water you will need in a survival situation. The earth is abundant with water, although a small percentage is suitable for drinking. I suggest that if someone is looking at the differences between freeze dried and dehydrated with regards to the water that is necessary versus the availability for drinking water… then you ought to be very concerned about your drinking water situation. I personally like the taste of freeze dried food better than dehydrated food, and its reconstituted ‘shape’ is basically identical to the original. rice, beans, wheat, etc.), freeze dried packaged foods, and dehydrated foods (great for home garden processing)… just to name a few. pastas), long term foods sealed in 5-gallon buckets (e.g. ![]() Store bought canned foods, store bought jar foods, home canned foods, foods that don’t require special treatment (e.g. I’ve always believed in diversification of food storage types. On the other hand, for those same foods, your body must use some of its water content to digest and process that same food… so in the end is their actually a difference? ![]() Overall, I do not believe that there is a significant difference in water consumption between the two methods, except for those dehydrated foods that are consumed without adding water. My experience with re-hydrating foods that I have previously dehydrated, are that I tend to use less than 1 cup of water per equivalent serving of vegetables than a freeze dried food. On the other hand, some dehydrated food can be consumed without re-constituting with water (particularly fruits or meats). The average amount of water required is a bit more than 1 cup of water per serving (which you would heat up first). I randomly pulled out a few freeze dried food packets that I have on hand here, so that I could read the directions. It does take more water to reconstitute freeze dried food than dehydrated food. The more it takes to cook the less you have to drink.” I recently received a good question from someone who asked… “How much water does it take to cook one serving of dehydrated food versus one serving of freeze dried food. Times vary, but typically are in the range of 12 to 24 hours until sufficient moisture has been removed from the food.įeeze-dried foods rehydrate quicker and dehydrated foods condense further, allowing more to be stored in less space. They are typically sliced thin, about 1/8 to 1/4 inch, and then are slow ‘cooked’ at temperatures ranging from 130 to 145 degrees Fahrenheit. The food dehydration process begins with quality vegetables, fruits, or meats. Since the food remains frozen during the process, the food’s cell structures do not change. Moisture is then removed in a vacuum chamber, as a low-level heat is applied to evaporate the ice without returning it to a liquid form. In the freeze-drying process, fresh or cooked foods are first flash frozen. Freeze-drying uses cold temperatures and dehydrating uses hot temperatures. How is freeze-dried food different from dehydrating?Īnswer: The temperature used to removed water. Dehydrated foods will shrivel in size as the moisture is removed. Dehydrated foods have 95% of their water removed for vegetables and 80% for fruits.įreeze dried foods retain their original color, form, size, taste and texture. This reduces the food’s weight by about 90%. Freeze-dried foods have 98% of their water removed.
