How Long Does Dehydrated Food Last [List]

Last Updated:

Publish Date:

There is no one universal answer for how long the dehydrated foods lasts because it needs to take into consideration for many factors and the condition of the food itself.

So I created a list of different types of foods and their storage life here.

If you buy dehydrated food from the store, you can just see the expire date on the packaging.

For DIY or homemade dehydrated food, you could see the table below to estimate know how long these foods last.

The list here not only contains dehydrated food but other types of dried foods as well.

After the list, I will talk about the factors that affect the dehydrated food lifespan and how to store it for long term.

Factors that affect the food lifespan

As I mentioned, how long the food lasts also needs to consider a few factors.


In warm or near room temperature will help the bacteria grow, in result spoiling the food.

United States Department of Agriculture, USDA, states that for every 10.8 degrees in temperature rise, you decrease the shelf life of stored food by half. The best range for food storage is a constant temperature between 40-60 degrees.



Light is a form of energy that can degrade the food value of foods.

Store food in dark areas, and pack the food in non-transparent container/package.


Moisture Content

Same as the temperature reason, with enough moisture will help the bacteria grow faster, for long term storage, foods should have 10% or less moisture content.



Foods store best when oxygen-free. You can put the oxygen absorber inside the package and seal it.



You can use a ziplock mylar bag to store your food.

It is strong than a regular bag.

Mylar bag is good because the light does not get through, so food doesn’t degrade, protect from moisture and bug infestation, put oxygen absorber inside to extend the shelf life even longer.
