Due to the high temperatures normally applied in conventional
evaporative concentration of fruit juices there is a decrease in the
quality of the juices during concentration, i.e. loss of color, flavors
and nutritional value (Petrotos and Lazarides, 2001). Several recent
studies show that concentration of fruit juices by membrane distillation
processes at considerable lower temperatures is a realistic
alternative to concentration of juices from oranges (Calabro et al.,
1994; Alves and Coelhoso, 2006), lime fruits
