RAPID CHARACTERIZATION OF SOY PROTEIN AND HYDROLYSATES BY CAPILLARY ELECTROPHORESIS

Rapid methods for characterizing soy proteins and their hydrolysates b y free-zone capillary electrophoresis were developed. The 7S- and 11S- rich protein fractions were separated by capillary electrophoresis (CE ). The relationships between degrees of hydrolysis and electropherogra ms were established. Protein hydrolysates were separated in less than 6 min. Data showed that the CE method can be used effectively for moni toring protein hydrolysis during processing and for fingerprinting var ious types of protein products.
