Synthèse des connaissances sur la déshydratation osmotique

Abstract

Synthesis of knowledge about osmotic dehydration. Among the preservation processes of vegetal products, osmotic dehydration presents an economic and a nutritional interest. This technique consumes a low quantity of energy, prolongs the period of availability of foodstuffs, and gives new and appreciated sensory properties to products. Therefore, the producers can sell their productions at better prices and the consumers are able to consume fruits and vegetables throughout the year. This technique is very easy to set up, especially in the developing countries due to its low cost. The aim of this article is to present a synthesis of the literature concerning the osmotic dehydration technique, and also to specify the new tendencies and directions of recent research.
