Citrus juice contains concentrated sources of nutrients and it can be considered as nutrient dense beverages.
Most of the soluble solids in fruit juices contain sucrose, glucose, fructose as well as organic acid such as malic and
tartaric acid (Telis, 2010). Besides that, fruit juice are low molecular weight. The physical properties of sugars in
fruit influence differently during spray drying. Sticky behavior of fruit powder is depending on the sugar content and
temperature of the product. Basically, drying and storage of powder fruit juices facing technical difficulties due to
their characteristic associated with the compositions. The important properties are solubility, melting point,
hygroscopicity and glass transition temperature, Tg (Telis, 2010; Das, 2002).
