摘要
研究了大孔树脂吸附和解吸曲霉型豆豉类黑精的特性。实验结果表明,采用大孔树脂精制曲霉型豆豉类黑精的最佳条件为:X-5树脂对曲霉型豆豉类黑精的吸附效果最好;X-5树脂在类黑精溶液pH为6,浓度为30．12mg/ml,吸附流速为1．5ml/min时吸附能力较强;在室温(20℃)解吸流速为1．5ml/min的条件下,以60%乙醇作为解吸剂时洗脱效果最好。
The adsorption and desorption of macro-porous resin on Aspergillus-type Douchi melanoidin were studied. The results showed that the sorption of X-5 resin is optimum. The study also showed that the X-resin has greater sorption at pH6.0, concentration 30.12 mg/ml and flow speed 1.5ml/min. With concentration of alcohol 60%, the desorption is the most effective at 1.5 ml/min and normal temperature.
