Average Shelf Life of Dehydrated Foods

Sadly, when I found this chart, it was during my very early days of prepping, I did not think to cite the source. My apologies to the author. Looking at some of the ingredients in the list, I suspect that some of them are commercially prepared freeze dried foods. 

Below is a chart to help you determine the shelf life of food stored in airtight containers at constant temperature of  70 degrees. **


All of the following products will store proportionally longer at cooler temperatures if kept at lower storage temperatures. Shelf life of 30+ years is perfectly feasible for many products!

Predicting actual shelf life of dehydrated foods is not an exact science, however there have been many studies done. 

  • In addition to the above average shelf life of food stored at a constant 70 degrees, you can dramatically increase your life expectancy by lowering the constant temperature. 
  • It is possible to double, triple or even quadruple the shelf life by lowering the temperature proportionally.
  • Some products, such as seeds, can even be frozen for dramatically increased shelf life. 
 


The Basic Rule Of Thumb:

Store you food storage in as low of temperature as possible to increase its shelf life and to retain nutritional value.
