Abstract

Les fruits et les légumes déshydratés se caractérisent par une teneur en eau de 4 à 7 % et une activité de l'eau de 0,4. En substance, les cellules des produits déshydratés ne sont pas endommagées. Le processus de séchage à l'air est doux et comporte quatre phases, au cours desquelles la température de l'air de séchage est maintenue à 60 degrés C. Durant la première phase, l'humidité relative de l'air de séchage peut augmenter pour atteindre 50 à 55 %, et est maintenue de façon sensiblement constante à cette valeur durant la seconde phase en conservant un échange sensiblement constant entre l'air de séchage et l'air frais. Au cours d'une troisième phase, l'humidité relative du moyen de séchage peut diminuer assez rapidement jusqu'au début de la quatrième phase. € ce moment, l'humidité relative peut asymptotiquement s'approcher d'une valeur d'humidité relative prédéterminée. Au cours du processus de séchage, on évite d'avoir des différences excessives de température et d'humidité relative entre le moyen de séchage et le produit, afin d'endommager le moins possible la structure cellulaire du produit.
