Method of producing compositions containing polyamines

摘要

Polyamine-containing compositions are produced by treating milk or a milk material with an ultrafiltration (UF) membrane at a pH lower than 5,5 and isolating and recovering polyamines from the resulting permeate using either one or more steps of an ion exchange process, membrane fractionation process and electrodialysis. Polyamine-containing compositions can be produced easily and at low cost.
