Results of this study showed similarity in precision,
accuracy and selectivity between FAAS and polarographic
methods for zinc concentration determination in infant
milk samples, especially after applying some
modifications which help canceling interferences. Despite
the high sensitivity of the polarographic method, FAAS
method was better due to the ease of its application. All
the studied infant milk samples were within the
recommended daily intake of zinc (5 mg) according to the
recommendations of the Committee on Nutrition of the
American Academy.
