Drying of fruits and vegetables is one of the oldest methods for preserving foods. Drying not only affects the moisture content of the product, but also changes other physical, chemical and biological properties of the product including enzymatic activity, microbial spoilage, viscosity, hardness, taste and aroma. In order to study the occurring changes in dried product, qualitative characterist...
