Abstract:
... The overall goal of this research was to examine differences in the composition, functionality and protein quality between Peruvian (PQ) and Northern (NQ) quinoa flours, and their isolates prepared by alkaline extraction/isoelectric precipitation. In the case of the flours, PQ and NQ were comprised of 13.6% and 12.8% protein, respectively. Water hydration (mean value = 1.65 g/g) and oil holding ca ...

Abstract:
... Protein isolates prepared from three pea cultivars by alkali extraction/isoelectric precipitation (AE-IP), salt extraction-dialysis (SE) and micellar precipitation (MP) were assessed for their surface (charge, hydrophobicity) and functional (water/oil holding capacity, solubility, foaming and emulsion capacities/stabilities) properties. Isolate yield was greatest for SE, followed by AE-IP and then ...
