Varietal identification of rice prolamins by capillary zone electrophoresis

Summary Capillary electrophoretic methods were developed to investigate the possibility of prolamin identification of four rice varieties i.e. Thai white fragrant rice KD105, Korkhor15, Thai white rice A, and a Chinese white rice H20. Two extraction methods were compared and varietal identification of rice prolamins was successfully accomplished by capillary electrophoresis in pH 2.5, sodium phosphate buffer containing 20% acetonitrile and 0.05% hydroxypropylmethylcellulose.
