A manufacturing method for a plant-based water-soluble dry powder, comprising the steps of; preparing a first mixture by mixing water with oats; comminuting solid components in the first mixture; heating the first mixture to a temperature range between 60° - 70° C.; adding α- and/or β-amylases and incubating for at least 40 min at 60° - 70° C.; filtering the first mixture; adding liquid fat or oil to the first mixture in a ratio of 65 wt. - % of the first mixture and 35 wt% liquid fat or oil; and spray drying the mixture of first mixture and fat or oil.

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.
