Drying is the oldest method of preserving food. Throughout history, the sun, the wind and a

smoky fire were used to remove water from fruits, meats, grains and herbs. By definition,

food dehydration is the process of removing water from food by circulating hot air through it,

which prohibits the growth of enzymes and bacteria.

Dried foods are tasty, nutritious, lightweight, easy to prepare and easy to store and use.

The energy input is less than what is needed to freeze or can, and the storage space is

minimal compared with that needed for canning jars and freezer containers.

The nutritional value of food is only minimally affected by drying. Vitamin A is retained

during drying; however, because vitamin A is light sensitive, food containing it should

be stored in dark places. Yellow and dark green vegetables such as peppers, carrots,

winter squash and sweet potatoes have high vitamin A content. Vitamin C is destroyed

by exposure to heat, although pretreating foods with lemon, orange or pineapple juice

increases vitamin C content.

Dried fruits and vegetables are high in fiber and carbohydrates and low in fat, making

them healthy food choices. Dried fruit has a higher concentration of carbohydrate than

fresh fruit; therefore, serving sizes tend to be smaller
