Procedeul are la baza utilizareapertractiei facilitate.Method for fractionation of amino acids mixturesProcedeu de fractionare a amestecurilor de aminoaciziDan Cascaval, Anca-Irina Galaction, Alexandra-Cristina BlagaGheorghe Asachi Technical University, IaşiFaculty of Chemical Engineering and Environmental ProtectionPendingThe patent describes a new method for selective separation ofamino acids from protein hydrolysates or fermentation broths.Therefore, by using the reactive extraction with D2EHPA, highefficiency and selectivity can be reached with low energy andmaterials consumption.Inventia se refera la un procedeu nou de separare selectiva aaminoacizilor din hidrolizatele proteice sau din lichidele defermentatie. Procedeul, extractia reactiva cu D2EHPA, permiteatingerea unor selectivitati si eficiente ridicate, cu consumuri redusede energie si materiale989
