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.

Method of making a milk calcium composition

A composition with a high ganglioside content is manufactured by a method characterized in that milk or milk-derived material containing ganglioside is dispersed in an ethanol solution so that the concentration of ethanol becomes 60&tilde;95%; after removing the precipitate which is generated by heating the solution to a temperature higher than 50&deg; C., the obtained supernatant is cooled to a temperature lower than 0&deg; C; and the obtained precipitate is recovered. The obtained composition with a high ganglioside content is used advantageously as a material for foods and drinks, medicines, chemical products, etc.
