There is always a possibility that insect larvae or harmful spoilage organisms may be present on the surface of dried fruits and vegetables. It is wise to prevent potential problems by pasteurizing the food, using one of the following methods.
Freezer Package the dried product in plastic freezer bags and store in the freezer a minimum of 48 hours. Remove and package for permanent storage.
Oven Layer dried food loosely in roasting pans and heat in a 175 degree Fahrenheit oven for 15 minutes or at 160 degrees Fahrenheit for 30 minutes. Remove and cool the product. Package for permanent storage.
