| Abstract: | Functional oligosaccharides have been widely used in the fields of food and biomedicine due to their appealing characters of anti-tumor, anti-inflammatory, anti-coagulation, anti-radiation, and other health functions. As an efficient separation technology, nano-filtration has attracted more and more attention in the separation and purification of functional oligosaccharides. In this paper, the separation mechanism of nano-filtration membranes for functional oligosaccharides was analyzed. Recent progress in their applications for the separation and purification of functional oligosaccharides was reviewed. The factors affecting the nano-filtration process were discussed, including the properties of feed solution, the operating parameters of membrane process, and the characters of membrane materials. The factors of feed solution mainly included its composition, concentration, viscosity, etc. The operating parameters were mainly reflected in the following: temperature, pressure, membrane surface velocity, pH, etc. The characters of membrane materials included both the microstructure and the surface properties. Finally, the challenges that the nano-filtration technology for the separation and purification of functional oligosaccharides is facing, such as the cost of equipment, the characters of membrane materials, and the membrane fouling, were presented. To promote the further application of nano-filtration, it is necessary to develop special membranes with low-cost and high performance, to focus more on the optimization of membrane system and the fouling control of membrane. |
