摘要: 研究了超滤膜从加纳籽中分离纯化5-羟基色氨酸的相关膜工艺条件及参数,并筛选出适合的聚砜超滤膜。研究结果表明,截留分子量为50 K的超滤膜分离纯化5-羟基色氨酸的效果要优于截留分子量分别为10 K和100 K的超滤膜。超滤膜分离纯化5-羟基色氨酸优化工艺条件:操作压力0.10 MPa、操作温度35 ℃、料液质量浓度1.141 mg/mL、pH值7.0,在此条件下5-羟基色氨酸转移率为83.5%,纯度可达90.5%。

Abstract: In this study,ultrafiltration technique was used for purifying 5-hydroxytryptophan(5-HTP)from Griffonia simplicifolia. The results showed that the ultrafiltration membrane with cut-off molecular mass of 50K was better than these of 10K and 100 K in separating and purifying 5-HTP.In order to improve 5-HTP purity and transfer ratio,the optimal separation and purification conditions were investigated and obtained as follows:operating pressure was 0.10 MPa,the temperature was 35 ℃,the raw concentration of 5-HTP was 1.141 mg/mL,and the pH value was 7.0.Under the optimum conditions,the 5-HTP transfer ratio was 83.5%,and the purity of 5-HTP was 90.5%.
