This study was conducted to investigate mineral contents of commercial powdered infant formula for obtaining basic data on infant nutrition. 11 Commercial infant formula based on cow’s milk were collected and the contents of macro minerals (calcium, phosphorous, sodium, potassium and magnesium) and trace minerals (iron, zinc and copper) were compared with Dietary Reference Intakes for Koreans (KDRIs). The overall mineral contents in 100 g and in 100 kcal of infant formula satisfied the recommended formula regulation and Codex. In infant formula during 0~5 monthly age, calcium, phosphorous, sodium, potassium, magnesium, zinc and copper could supply 233.1%, 273.5%, 156.7%, 142.0%, 150.8%, 209.3%, 171.1% of recommended daily mineral intakes, respectively. The content of iron in 0~5 monthly age formula supplied 2842.6% of recommended daily iron intakes. In infant formula during 6~11 monthly age, calcium, phosphorous, potassium, magnesium, iron, zinc and copper satisfied their recommended daily intakes. However, sodium only supplied 76.6% of its recommended daily intake. Intake ratio between Ca/P, Ca/Mg, Ca/Fe, Na/K and Zn/Cu in infant formula during 0~5 monthly age were 1.7±0.2, 11.0±2.4, 64.9±10.0, 0.3±0.1, and 9.6±1.0, respectively. Intake ratio between Ca/P, Ca/Mg, Ca/Fe, Na/K and Zn/Cu in infant formula during 6~11 monthly age were 1.7±0.2, 12.9±1.5, 80.1±13.8, 0.3, and 9.4±1.1, respectively. From this study, evaluation of mineral contents of commercial infant formula was established, which could strengthen the basic information on infant nutrition.
