Abstract

Milk contains completeness of 5 main nutrients, namely carbohydrates, protein, fat, vitamins and minerals. Milk contains many minerals, one of which is zinc. This study aims to determine the concentration of zinc in bulk milk powder which is traded in the Inpres, Masomba and Lasoani markets, Palu City, Central Sulawesi. Analysis of zinc minerals using the air-acetylene flame flame method with atomic absorption spectrophotometry at a wavelength (λ) of 213.90 nm. The results showed that the analysis of zinc levels in the bulk/kiloan milk powder samples A, B and C, respectively, was 3.13 mg/kg; 3.29 mg/kg; 5.85 mg/kg. From the data it is shown that the zinc content in bulk milk powder which is traded in the Inpres, Masomba and Lasoani markets, Palu City, Central Sulawesi meets the requirements set by the quality requirements of SNI No. 01-2891-1992, namely the zinc (Zn) content in powdered milk is a maximum of 40.0 mg/kg.
