Foods that have been freeze dried, retain their taste and aroma, unlike foods that have been dehydrated. You can shop and save food that’s been freeze dried for several months on counting.
Easy to Prepare
Bringing back the flavor of food preserved through dehydration requires the use of seasoning and cooking the food for quite some time. This is not the same for freeze dried food, which only requires the addition of a little water for the food to be readily prepared.
There are No Additives Used in Freeze Dried Foods.
The additive contents in prepackaged foods may pose certain health risks. Some of these additives include food dyes, trans fats and Sodium Nitrate. The additives might end up affecting the nutritional value found in the food. Freeze drying ensures that no additives are required to preserve the Food.
