平板超滤膜法在分离纯化天然牛磺酸中的应用

Application of flat UF in separation and purification of natural taurine

介绍了天然牛磺酸提取工艺中存在的问题及膜分离技术,研究了4种不同规格超滤膜在章鱼下脚料中提取天然牛磺酸中的应用,从膜通量、蛋白去除率、牛磺酸收率、膜污染和膜清洗等各方面考察了不同材质、不同切割分子量的平板超滤膜分离性能.得出了1#平板超滤膜(MWCO 30 000g/mol,CA)为从章鱼下脚料中分离牛磺酸的较佳分离膜.

This article elaborates on the problems that exist in the separation and concentration of nature taurine and membrane separation technology. It analyzes how four different types of ultrafiltration membrane are applied to extract nature taurine from octopus scraps. The separation performance of flat ultrafiltration membranes which have different materials and interception is studied in terms of the membrane flux, the removal rate of protein, the yield of taurine, the repeated utilization of the membrane. The article finds out that 1# flat UF （MWCO 30000g/mol,CA）is the preferred membranes.
