APPLICATIONS OF MEMBRANE TECHNOLOGY TO FOOD-PROCESSING

Membrane technology is still evolving, finding more and more applicati ons in food processing. Conventional techniques such as micro- and ult rafiltration or reverse osmosis can now be regarded as more or less st andard unit operations that are being implemented in numerous processe s. Newer techniques such as pervaporation and bipolar membrane technol ogy offer new possibilities, but are still in the process of developme nt. The present trend of membrane technology in food processing is to produce more specialized membranes that are dedicated to one process, one product or even only to improving the quality of an existing produ ct.
