Physicochemical properties and functional characteristics of ultrasound-assisted legume-protein isolates: a comparative study.

Sonicated protein isolates were recovered from and to develop a functional matrix by assessing the physicochemical and functional properties. The plant protein isolates were prepared from powdered materials followed by sonication in alkaline medium using a Box-Behnken design. pH (6-10), a buffer-to-material ratio (5:1 to 15:1) and sonication time (0-20 min) were taken as independent variables, whereas protein yield was taken as the dependent variable.
