Drying is a complex process frequent in most of the food processing industries. The functional
properties of food components, highly affected by the drying processes, significantly influence the scope of their application and commercial value. Food biopolymers such as proteins, carbohydrates, and mixed flours are important due to their functional properties including water solubility, swelling index,water/oil holding capacity, porosity, emulsification, foaming, bulk density, viscosity and gel properties.
