Is it really a good idea to hive away freeze dry out intellectual nourishment for a prospicient - term survival post ? It may be an attractive proposal for the survivalist in you , but you probably did n’t bargain on what exactly the process of immobilise dry out involves — and its price .
How to Carry a Ton of Food on Your Back
The mental process of freeze drying plays with the properties of urine within nutrient . When freeze out drying , a make portion of nutrient isflash frozenunder a vacuum . At low insistency , all but2 - 5 % of the water in the nutrient sublimate , moving quickly from a hearty to gas frame . The evaporation of body of water in this process allows the intellectual nourishment to keep its shape and decrease the weight by up to90 % – a large plus for those who need to “ bug out ” in a hurry due to a disaster .

Shelf life of freeze out dry food
Freeze dry nutrient last a niggling bit longer than dehydrated ones . Most block dried foods that you buy are seal under nitrogen in resilient promotional material , allowing for anywhere from atwoto twenty - five year shelf life . Freeze dried fruits are on the miserable terminal of the shelf life-time spectrum , lasting a little over two years .
Once the cachet on a package of freeze dried food is get around , the shelf living clock is retick , with most toothsome forsix month . There ’s a speedy slack in shelf life if it ’s stored in a humid area .
Post - apocalyptical eating is expensive
Freeze dry foods are rather expensive – $ 1 to $ 2 per serving of a side ravisher likemacaroni and cheeseand $ 3 for a serving of land beef . These are bulk prices – individually tamp entrees cost$6 to $ 8a piece .
One is easy looking at $ 10 to $ 15 buck a twenty-four hour period per person to sustain a dieting of freeze dry out food . Remember , this is food you might end up eating for hundreds of meals if a crack-up of companionship never comes .
Dehydrating food yourself is a slenderly tinny alternative , but ask a large amount of work and is far more susceptible to contamination .
The pee problem
In accession to cost , another problem rears its head with freeze - dry intellectual nourishment . immobilize dried food must be reconstituted to be deplete , necessitating a big ( and sportsmanlike ) water provision to dine — and that ’s on top of the light water you need for drinking .
Clean H2O will likely be in inadequate supply in a post - apocalyptic survival of the fittest scenario . Water can be boiled or hive away in advance , whilebleachand iodine are useful in killing pathogen likeGiardia lambliain fresh piddle . But that ’s a sight of body of work to decontaminate your water , and you might desire to use that water for drinking rather than restructure up your frost - dry out ice cream .
Making matters worse is the fact that eating freeze down dried food without reconstitution could hypothetically induce you to desiccate .
The verdict : The post - apocalypse will not be immobilize - dried
survive a long - term disruption in the solid food supply with freeze down dried food would take tremendous planning , a considerable amount of money , and one variable star – a in force , unwavering water system supply . So it ’s probably not a good retentive - term root after civilization falls .
If , however , you are implicated about prepare yourself for a small disruption in the food supply due to a hurricane or other natural distaster , storing some freeze dried food in the house might be a good idea . 72 - 60 minutes food kits are sold onAmazonand in some large box stores .
In the meantime , do n’t block about the canned solid food lying in your pantry . tinned goodness are hefty , but they are safe for several old age and , in the fount of vegetables like corn whiskey and immature beans , also contain a water supply supply . It might not taste good , but in a pinch , asparagus water could keep you alive .
