| Popis: | Methodologies for the determination of vitamin B(2) in food matrixes and a premix using simple sample conditioning steps coupled with a convenient and cheap electrochemical sensing device are presented. Electrochemical analysis based on differential pulse voltammetry (DPV) coupled to carbon electrodes gave a well-defined reduction peak at -0.42 V versus a Ag/AgCl quasi-reference electrode. Using a straightforward sample preparation step, vitamin B(2) can be measured successfully in a nutritional premix and food products. Standard additions of riboflavin were used to confirm the analyte concentrations and to provide precision data. |
