摘要
为纯化红枣多糖,采用超滤技术对红枣多糖提取液进行处理,在单因素试验的基础上,以膜通量为指标,采用正交试验对纯化工艺条件进行优化。结果表明,超滤纯化红枣多糖的适宜工艺条件为操作压力0.12 MPa、温度32℃、pH 6.5,在此条件下,膜通量达到16.4 mL/(m2·s)。超滤工艺简单、有效,可用于红枣多糖的纯化。
In order to purify polysaccharides from jujube, the ultrafiltration technology was used to treat the jujube polysaccharides extracts. Based on single factor test, the technology parameters were optimized by membrane flux as index. The results showed that the optimization parameters were that operation pressure 0.12 MPa, temperature 32 ℃ and pH 6.5. Under this condition, membrane flux was arrived 16.4 mL/（m2.s）. The ultrafiltration was a simple and effective method for purifying polysaccharides from jujube.
