Food preservation methods are getting popular day by day. Especially during this pandemic period, we all are concerned about our health and food security. Food preservation is also important while going for a long road trip or hike. Many of us like to carry those with us. Whether it is freeze-dried or dehydrated foods, the main purpose is to store the foods in the right way.
Previously people dehydrated foods to store for a longer period. People use the sun rays, fire, and smoke to dry and preserve foods like fruits and vegetables. Still many people in the world rely on technology to create dried food. The freeze-drying method to store foods is a pretty modern technique which is invented in the early 1900s. But Freeze-dried foods have a longer shelf life than dehydrating food items.
Both methods tend to alter the natural taste of food. But freeze-drying is the better method for preserving your food. Because it keeps food’s natural flavor and smell. Freeze-drying removes the 98 percent water from foods while removing only about 80 percent of the water.
So, a freeze-drying method has lots of benefits compared to the dehydration method. It typically makes food lighter in weight. People can easily carry it when required. Especially when you are on the road or hiking with a backpack, you can easily carry foods that are preserved by the freeze-drying method.
