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.
Claims8
A method of concentrating phospholipids, the method comprising:
- subjecting a dairy composition comprising butter serum or buttermilk to a first ultrafiltration, wherein the first ultrafiltration yields a first permeate and a first retentate;
- treating the first retentate with carbon dioxide;
- subjecting the first retentate to microfiltration, wherein the microfiltration yields a second permeate and a second retentate;
- treating the second retentate with carbon dioxide;
- subjecting the second retentate to a second ultrafiltration, wherein the second ultrafiltration yields a third permeate and a third retentate;
- and
- collecting the third retentate, wherein the third retentate comprises at least about 30 wt % phospholipids.
