Optimization Process for Separation of Polysaccharides from Crassostrea gigas Using Ultrafiltration Membrane
摘要
Abstract
Objective] To optimize the methods of separating polysaccharides from Crassostrea gigas (CGPS).[Methods] Ultrafiltration membrane was used, single factor and orthogonal experiment were carried, and the molecular weight distribution and process of CGPS were studied.[Results] Results indicated that the flux of ultrafiltration membrane with molecular weight cut off of 10 kD was was better.The CGPS cut off by the membrane hasmolecular weight with 1.2 ×103 kD, and the permeate liquor has molecular weight of 4.4 kD.The orthogonal tests showed the main influencing factors are temperature of solution and operating pressure, while pH had less influence.In overall consideration of the life of membrane and production costs, the optimum technology of ultrafiltration are temperature 30 ℃, operating pressure 0.04 MPa and pH 7.0.[Conclusion] This study is expected to provide certain reference for extracting.关键词
