%X The separation of alanine by emulsion liquid membranes in laboratory scale is studied, thus explores a new way for recovery of alanine from the "secondary isoelectric point crystallization" mother liquid in the production process of gourmet powder. D2EHPA, Span 80 and Sulphonating-kerosene are used as carrier , surfactant and diluent, resppectively, to compose the liquid membrane system. The affecting factors of ELM extraction are inverstigated and some suitable separation conditions are established. The extraction of alanine in one batch stage is over 60% and alanine is concentrated over 3 times. The demulsification process in high electrostatic field with box install is researched and the functional relation between the demulsification rate and the related operating factors is obtained.
