The reduction of humidity in food is an effective way to prevent the development of microorganisms and therefore, increase its shelf life and availability for consumption. Indeed, this method was already used in prehistoric times to conserve figs or other fruits. Another advantage of the drying process applied in the food industry is the weight reduction obtained when food is dehydrated and consequently the reduction of the associated cost of transport.
