Separation of amino acids (a-phenylglycine and aspartic acid) and by-products (betaine), as they are biocompounds of food and pharmaceutical interest, was carried out with a new extraction technology using extractant-impregnated resins. This study demonstrates that this new technology is an alternative to the conventional separation processes. Extraction with impregnated resins (EIR) is a novel hybrid technology which combines the high capacity and selectivity of liquid-liquid extraction technique, with the advantages of separation processes with ion exchange resins, which allow to process high quantities of diluted solutions, using simple and low cost equipments, such as fixed or fluidized beds. In this work separation of amino acids was investigated by impregnation of Amberlite XAD-4 resin with tri-alkylmethylammonium chloride (TOMAC) and for betaine separation the same resin was impregnated with dinonilnaftalensulfonic acid (DNNSA).
