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.
Claims20
A method of concentrating phospholipids, the method comprising:
- subjecting a dairy composition 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.
A system for concentrating phospholipids, the system comprising:
- a first ultrafiltration apparatus configured to subject a dairy composition to a first ultrafiltration, wherein the first 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;
- a second ultrafiltration apparatus configured to subject the second retentate to a second ultrafiltration, wherein the second ultrafiltration yields a third permeate and a third retentate, wherein the third retentate comprises a solution comprising at least about 30 wt % phospholipids;
- a treatment chamber housing the microfiltration apparatus and the second ultrafiltration apparatus;
- and
- a carbon dioxide injector coupled with the treatment chamber, the carbon dioxide injector configured to inject carbon dioxide into the treatment chamber, the microfiltration apparatus, and the second ultrafiltration apparatus.
An edible composition comprising:
- a total fat content of about 40 to about 45 wt %, wherein about 90 wt % of the total fat content comprises phospholipids;
- a total protein content of about 40 to about 75 wt %;
- and
- a lactose content of about 3 to about 5 wt %.
