A total of 101 samples of convenience baby food products were analyzed by microwave digestion and mineral nutrients (iron, zinc, calcium, magnesium) were determined by inductively coupled plasma optical emission spectroscopy (ICP-OES). By type, the samples included 44 rice porridges, 40 soft-boiled rices, 11 purees, and 6 powders. The mean values for iron (Fe) content were 0.05 to 0.45 mg/100 g (excepted powder type, mg/l0 g). This was equivalent to 22.35% for rice porridge, 10.55% for soft-boiled rice, 9.88% for puree and 2.74% for powder type compared to the KDRIs (Dietary Reference Intakes for Koreans), respectively. The mean values for zinc (Zn) was 0.06 to 0.28 mg/100 g (excepted powder type, mg/l0 g) and the KDRI ratio was the lowest at 5.94% in puree, with 27.76%, 28.95% and 10.91% in rice porridge, soft-boiled rice and powder type, respectively. Calcium (Ca) content relative to KDRIs was relatively low compared to other minerals, with 6.65% for rice porridge, 3.61% for soft-boiled rice, 6.24% for puree and 3.07% for powder type, respectively. The magnesium (Mg) content of baby food ranged from 13.4% to 39.0% compared to KDRIs, and was included in all baby food as a whole. For balanced nutritional mineral supply to infants, it is recommended that information on mineral sources and ingredients in convenience baby food be clearly provided to ensure proper growth and development.
