Abstract
Pulse protein isolates, food compositions containing such isolates, and methods for preparing pulse protein isolates are disclosed. In some embodiments, the methods include extracting pulse proteins from a milled composition and applying the extracted proteins to an ultrafiltration process to produce pulse protein isolates with desirable organoleptic characteristics.
Claims37
A method for preparing a pulse protein isolate, comprising:
- obtaining a milled composition;
- extracting protein from the milled composition comprising pulse proteins in an aqueous solution at a pH of from about 1 to about 9 to produce a protein rich fraction containing extracted pulse proteins;
- applying the protein rich fraction to an ultrafiltration process comprising a semi-permeable membrane to separate a retentate fraction from a permeate fraction based on molecular size at a temperature of from 2° C. to 60° C.;
- and
- collecting the retentate fraction containing the pulse protein isolate.
