Abstract:Objective]To extablish a method to detect the benzoyl peroxide contained in wheat flour by HPLC technique. Method] With a column of Novapak C18(3.9 mm×150 mm), the Benzoyl peroxide in wheat flour was well separated with the mobile phase composing of acetonitrile-0.1% phosphoric acid solution (2∶3) and the monitoring wavelength of 230 nm.Result] The recovery varied from 98.9% to 103.9% and the relative standard deviation(RSD) was from 1.2% to 1.7% by this determining method. Conclusion] The method was simple and convenience,with excellent reproducibility, good accuracy and the satisfactory results.
