Freeze Drying

Freeze drying dehydrates food by using low temperatures to remove moisture.

And since freeze drying doesn’t use heat, your food keeps more nutrients than with canning and dehydrating with heat.

Using a freeze dryer to preserve your food is great for adding to your home food storage!

Some freeze dried food can last up to 25 years.


This method involves heat to remove enough moisture to prevent bacteria from growing.

Dried foods then need to be packaged to protect them from invading insects and moisture.

You can dry foods with an electric food dehydrator or in your oven.


Canning involves packing a food container, such as a can or jar, and applying enough heat to kill any bacteria that might be present.

The heating and cooling process forms a vacuum seal.

The seal prevents other microorganisms from contaminating the food in the jar or can.

There are two main ways of canning food.

  • Water bath canning – this uses a water bath to preserve high acid foods
  • Pressure canning – this uses a pressure canner to preserve low acid foods

Using Sugar

Sugar preserves food by removing the amount of water available for bacteria to grow.

Heat treatment is usually used as well to reduce the amount of bacteria already present.

Foods preserved this way are sealed in air-tight containers to keep them from being contaminated.

This method is commonly used to preserve jams and jellies.


This method involves packing your food in acid.

The acid reduces the food’s pH level to a low enough level that prevents bacteria from growing.

Some acids that can be used are vinegar and citric acid. 


This method uses salt to prevent bacteria from growing.

It works by drawing out the water that bacteria need to grow.

A ten percent concentration of salt will achieve that.

Some foods that can be preserved this way are meats and fish.


Storing food in cold temperatures stops bacteria from growing and slows down the action of the enzymes in the food that cause it to go bad.

Most foods can be preserved by storing them in a freezer.
