Extraction of L-Theanine Using Chiral Supported Emulsion Liquid Membrane

Abstract:

Supported emulsion liquid membrane using copper(Ⅱ) N-dodecyl-(L)- hydroxyproline as a chiral carrier was used as a novel technique to extract L-theanine. The effects of initial concentration of L-theanine in the feed phase, chiral carrier concentration in the membrane phase and salt concentration in receiving phase on extraction performance were studied and some optimum conditions were achieved.
