ABSTRACT
Electrophoresis separates charged molecules by using an electric eld. Thus, during the separation, charged molecules of different sizes, in an electric eld, will migrate at different velocities and thus will be separated. Electrophoresis can be divided into two types: (a) free solution electrophoresis (capillary electrophoresis) and (b) supporting medium (e.g., paper, gel, and lm) electrophoresis. This chapter will focus only on isoelectro-focusing (IEF) electrophoresis, gel electrophoresis, and Western blot analysis. The use and applications of these bioanalytical tools in food analysis and research will be discussed.
