Dehydration is one of several ways to store food. The process involves removing most of the water from food by using heat. Heat, regardless of the source, kills bacteria in the food. Bacteria are what cause food to spoil, and they require water to grow. So, when you heat a food and remove its water, you create a new product that will take much longer to spoil.
Dried foods are also great for avoiding waste. When you grow your own food, you often end up with more than you can eat at once. Freezing is one way to store surplus, but your food will be ruined if you lose power for a significant amount of time. Canning is another method, and a good one. When done properly, canned foods are safe and last for years. Dehydrating foods is your third option for storage. Drying foods is less risky than canning. Although you have to take care when drying your foods, there is much less potential for contamination by botulism and other bacteria than when canning.
Dehydrated foods are tasty and make great snacks. It takes time to dry food, but most of that time is simply letting the food sit. For the effort put in, you get a really nice snack. Dried fruits, meats, and vegetables are fun to eat and make an easy and quick snack that the kids can grab whenever they are hungry.
