Weight Reduction. All fresh foods contain water, which is its main source of weight (fruits are more than 80 to 90% water). However, during drying about 98% of the moisture in the food substance is removed, which reduces the weight by as much as 90%, making it lighter to carry backpacking. Aside from freeze-dryingâs use in backpacking and camping, the military also freeze-dries foods to make it easier for one person to carry large amounts.
Freeze dried food is flash frozen and then placed inside a vacuum pouch or container. Unlike the long dehydrating process, water in freeze dried food vanishes quickly. The fast removal of moisture prevents the food from shriveling or looking âdeformedâ as it can often do during the dehydration process.Typically, freeze dried food rehydrates more quickly than dehydrated food. Water and time (i.e. patience) are needed for both types of long-term storage food.reeze dried food is flash frozen and then placed inside a vacuum pouch or container.
