However, the use of osmotic evaporation as a direct process to
concentrate fruit juices is difficult to implement at industrial scale,
since the large amount of water present in the initial juice promotes
a fast brine dilution, which negatively affects the water removal
from the juice. In this context, the coupling of reverse
osmosis and osmotic evaporation can be considered a promising
alternative, since it results in products with similar solid content
than those obtained by conventional methods (such as vacuum
evaporation), with less pronounced effects on the juice’s quality.
