The traditional methods of juice concentration, such as vacuum evaporation, usually employ high temperatures to remove water. However, heat can cause undesirable changes in the product's sensory and nutritional properties, such as color changes, off-flavor formation and reduction in the nutritional value. In this context, an alternative for thermal evaporation is the use of membrane concentration processes. Membrane processes are able to concentrate juices at room temperature, causing little or no damage to the product (Girard & Fukumoto, 2000).
