Abstract
The present disclosure provides an albumin enriched PPI extraction process and albumin enriched PPI produced by the process and use of albumin enriched PPI. The albumin enriched PPI extraction process comprises steps of a) protein extraction from aqueous solution comprising pea flour, b) separation of solids from the aqueous solution, producing a protein-rich liquid fraction, and c) precipitation of protein by use of Na, Ca, or Mg salt or combination thereof, thereby producing an albumin enriched PPI.

1-82. (canceled)
A method of making an albumin-enriched pea protein isolate comprising:
- a) performing a protein extraction of pea flour with an aqueous solution,
- i) at a pH of about 7 to 10,
- ii) at a temperature of about 18° C. to 60° C., and
- iii) for about 30 minutes to 60 minutes for the protein extraction;
- b) separating solids from the aqueous solution in step a) to produce a liquid fraction;
- c) precipitating protein from the liquid fraction by
- i) precipitating protein at a pH about 4 to 8, at a temperature of about 18° C. to 95° C. for about 5 to 60 minutes to produce the albumin-enriched pea protein isolate,
- wherein step a) and/or step c) comprises using 0.1%-5% sodium hexametaphosphate.
The method of claim 82, wherein the pH of step a) is 8 to 9.5.
The method of claim 82, wherein the temperature of step a) is about 50 to 60° C.
The method of claim 82, wherein step a) is performed for about 30 minutes.
The method of claim 82, wherein the pH of step c) is 4 to 7.
The method of claim 82, wherein the temperature of step c) is about 50 to 60° C.
The method of claim 82, wherein step c) is performed for about 30 minutes.
