Membrane technology in the vegetable and fruit processing has been applied for concentration using RO membrane and for clarification using UF or MF membrane.
Recent technological advances related to the development of new membrane system, advanced separation and recovery of valuable components, improvement quality, saving energy consumption and reduction of environmental negative impact, have expanded the range of membrane separation.
We have developed two new membrane systems. One is RO concentration system for material including the solid. Conventional RO system has been used for only juice concentration including the solid below 0.5mm particle size, by this new RO system, it is possible to concentrate liquid including 0.5mm-10mm particle size solid.
Another is electrodialysis system for reduction of nitrate in a green vegetable, the characteristic of this system is to be operated under high concentration (Brix20), low velocity and low temperature condition.
