This chapter introduces fruit juice concentration methods by principles of evaporation; and discusses the consequent loss of volatile substances and decomposition of valuable components. The chapter also explores the method of increasing concentration with integrated membrane operations based on the principle of reversed osmosis that helps decrease waste of valuable nutritional components. Fruit drying methods are based on water removal from solid material and for controlling knowledge of moisture transport and principles of water removal are essential. Besides traditional drying technologies, vacuum drying, freeze drying, and osmotic drying are also used for fruit drying as these technologies help to keep main nutritional components of raw material.
