Juice is traditionally concentrated by multi-stage vacuum or refrigeration, resulting in a loss of fresh juice flavors, color degradation and a “cooked” taste due to the thermal effects, which not only makes big power consumption, but also makes high production cost.
Membrane separation technologies have many advantages of reducing power consumption, high production efficiency, simple process, continuous working at room temperature, etc. So it is specially and widely applicated in hot-sensitive food industries, pharmaceutical and bio-chemical, etc.
