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.
You do lose some flavor when food is frozen but freezing can be a very good way to preserve the nutritional value, texture and flavor of many foods. The initial quality of the food and the length of time between harvest and freezing are important factors. As long as the food was grown in a high-quality way (for example, organically grown) and was fairly fresh at the time of freezing, the overall nutrient retention in a frozen food can be quite high. In other words, many of the vitamins and minerals will keep fairly well in frozen foods.
