Current aspects of soy protein fractionation and nomenclature

Significant advances have been made recently in studying the basic physico‐chemical properties of the major soy storage proteins and their subunits using such techniques as differential solubility, ion exchange chromatography, gel filtration chromatography, immunoelectrophoresis, isoelectric focusing and dissociating gel electrophoresis. This paper reviews and discusses the principal findings from this work and summarizes the current status of the nomenclature of the major soy storage proteins, e.g., 11S glycinin, 7S β‐conglycinin and γ‐conglycinin and their subunits.
