dehydration has been known since long time ago, its use is expanding by the current lifestyle. Dried vegetables and fruits can be easily produced and stored and transported at relatively low cost. In addition, the resulting products have characteristics other than those of fresh products, expanding and diversifying the existing market. To date, most of dehydrated vegetables and fruits are obtained by convective drying, normally preceded by blanching treatment or osmotic dehydration. Although products with a long shelf-life are obtained by this method, their quality, in most of the cases, is quite far from that required by today's consumer, due to the physical and chemical changes that are originated.
