Dehydration techniques are methods used to remove moisture from food, helping to preserve it for longer periods. One common technique is using a dehydrator, a device that circulates warm air around food to evaporate water. This process intensifies flavors and makes snacks like dried fruit and jerky easy to store and transport. Another popular method is air drying, where food is hung in a well-ventilated area to allow moisture to escape naturally. This technique is often used for herbs and some fruits. Both methods are simple and effective, making it easy to enjoy healthy, long-lasting snacks at home.
