[en] Zinc as a micro nutrient, has important roles in human metabolism system. It is required by the body in appropriate amount from food intake. Due to the very low concentration of Zinc in food, high selectivity and sensitivity analysis technique is required for the determination, such as Neutron Activation Analysis (NAA) and Atomic Absorption Spectrometry (AAS). In this experiment, both methods were compared in zinc analysis of food samples. The subject of this experiment is to examine of those methods conformity and improving the technique capability in zinc analysis in food sample. Those methods were validated by analyzing zinc in SRM NIST 1548a Typical Diet and were tested its accuracy and precision. The results of Zn concentration were 25.1 ± 2.14 mg/kg by NAA and 24.1 ± 1.40 mg/kg by AAS while the certificate value was 24.6 ± 1.80 mg/kg. Percentage of relative bias, %CV, μ-test score and HORRAT(Horwitz ratio) value given by NAA were 2%, 8.5%, 0.18 and 0.9 respectively, while %relative bias, %CV, μ-test score and HORRAT value given by AAS were 2%, 5.8 %, 0.20 and 0.6 respectively. The result obtained for Zn concentration in various food samples by NAA and AAS were varied from 13.7 – 29.3 mg/kg with mean value 19.8 mg/kg and 11.2 – 26.0 mg/kg with mean value 17.3 mg/kg (author)
