Dehydrating
One of the oldest methods of food preservation is dehydration. It is simple, safe, and easy to do. Dehydrated foods take up less storage space and do not require refrigeration. The food is lightweight which makes it ideal for camping as well as an anytime snack.
Dehydration removes moisture from the food. This prevents bacteria, yeasts and molds from growing and causing spoilage. Dehydration also slows enzyme activity in food which can cause color, texture, and flavor changes.
