Freeze concentration or cryoconcentration is a method for recovering
a food solute from a solution based on the separation of pure ice
crystals from a freeze-concentrated aqueous phase. As compared to
evaporation and membrane technology, freeze concentration has
some significant potential advantages for producing a concentrate
with high quality because the process occurs at low temperatures
where no vapor/liquid interface exists resulting inminimal loss of volatiles.
Thus, the flavor and quality of freeze-concentrated products are
exceptionally high, especially relative to their counterparts produced
by evaporation
