Zusammenfassung:Methods and systems for separating and purifying monatin are described. In the production of monatin, a mixture is formed which includes monatin, starting materials and intermediates. The methods and systems include a membrane having a zeta potential of from about -19 to -6 such that the membrane rejects greater than about 90 % of the monatin. In some embodiments, the membrane is a nanofiltration membrane. La présente invention concerne des procédés et systèmes permettant de séparer et de purifier la monatine. Pour produire la monatine, on réalise un mélange comprenant la monatine, des substances de départ, et des intermédiaires. Les procédés et systèmes mettent en oeuvre une membrane présentant un potentiel zêta d'environ -19 à environ -6 conçue pour rejeter plus d'environ 90% de la monatine. Dans certains modes de réalisation, la membrane est une membrane de nanofiltration.
