Abstract
Phospholipid concentration methods involve use of a dairy composition, such as buttermilk or butter serum, as a starting material. The dairy composition is subjected to a first ultrafiltration, yielding a first permeate and a first retentate. The first retentate is treated with carbon dioxide and subjected to microfiltration, yielding a second permeate and a second retentate. The second retentate is treated with carbon dioxide and subjected to a second ultrafiltration, yielding a third permeate and a third retentate. The third retentate includes at least 30 wt % phospholipids.
Claims7
A system for concentrating phospholipids, the system comprising:
- a first ultrafiltration apparatus configured to subject a dairy composition comprising butter serum or buttermilk to ultrafiltration, wherein the ultrafiltration yields a first permeate and a first retentate;
- a microfiltration apparatus configured to subject the first retentate to microfiltration, wherein the microfiltration yields a second permeate and a second retentate different from the first permeate and the first retentate;
- a second ultrafiltration apparatus configured to subject the second retentate to ultrafiltration, wherein the ultrafiltration yields a third permeate and a third retentate different from the second permeate and the second retentate;
- and
- a carbon dioxide injector configured to inject carbon dioxide into the system such that the first retentate and the second retentate are treated with carbon dioxide,
- wherein the third retentate comprises a solution comprising at least about 30 wt % phospholipids.
