本文分析了等电点—离子交换法提取谷氨酸的工艺特点,研究了弱酸性阳离子树脂优先脱铵的可行性和操作条件,提出了“弱酸性树脂脱铵—等电点结晶—强酸性树脂吸附谷氨酸”的工艺流程,并将其效果与文献资料进行了比较。
In this paper, the characteristics of glutamic acid extraction by isoelectric point-ion exchange method were analyzed. The feasibility and operating conditions for the preferential deammoniation of weakly acidic cationic resins were studied. The “weak acid resin deammoniation-isoelectric point crystallization-strong acidity Resin adsorption of glutamic acid ”process, and the results were compared with the literature.
