Abstract
Urea is readily isolated and recovered from natural products. Urea can be brought into the permeate side by treating a urea-containing fraction extracted from natural products or sewage containing urea, with a nanofiltration (NF) membrane or reverse osmotic (RO) membrane. A milk-derived composition containing urea at a level of more than 0.2% of the total solids can be obtained by treating natural products such as milk or milk materials with an NF membrane or RO membrane to bring a fraction containing urea into the permeate side.
