Abstract

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 supplied2842.6% 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${\pm}$0.2, 12.9${\pm}$1.5, 80.1${\pm}$13.8, 0.3, and 9.4${\pm}$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.

시판되고 있는 11종의 영아용 조제분유(0${\sim}$5개월용, 6${\sim}$12개월용)의 열량 및 Ca, P, Na, K, Mg, Fe, Zn, Cu의 함량을 표시된 첨가수준을 이용하여 비교분석하였다. 조제분유 100g및 100 kcal내 무기물 함량과 무기물 함량의 비율 (Ca/P, Ca/Mg, Ca/Fe, Na/K 및 Zn/cu)을 제품별로 분석하고 한국인 영양섭취기준에 의거하여 적합성을 고찰한 결과는 다음과 같다. 분말형 조제유 100 g당 각 무기질의 함량은 전반적으로 고제분유기준에 충족됨을 알 수 있었다. 100 kcal를 기준으로 영양소 적정량을 제시한 Codex 규격과 비교분석한 결과, Ca, P, K, Zn, Fe, Cu는 Codex 기준 함량을 모두 충족하였으나 Mg의 경우 국내제품 한 종류를 제외한 나머지 시료들이 전반적으로 Codex의 권장함량을 충족시켰다. 영아의 에너지 필요추정량을 기준으로 한국인 영양섭취기준과 비교, 분석한 결과, Ca, K, Mg, P, Na, Cu 및 Zn의 경우 비교적 충분섭취량에 근접하였으나, Fe의 경우 충분섭취량의 2842.8%를 함유하여 독성을 우려하였으나 상한섭취량을 벗어나지는 않았다. 6${\sim}$ll개월용 제품의 경우, Ca, P, K, 및 Cu이 각각충분섭취량을 함유하고, Fe와 Zn가 각각 권장섭취량이상을함유하고 있는 반면 Na이 충분섭취량의 약 「6.6% 정도 함유되어있음을 알 수 있었다. 무기물간의 비율을 분석한 결과, Ca/P 비율의 경우, 평균 1.7${\pm}$0.15(0${\sim}$5개 월), 1.73±0.16(6${\sim}$ll개월), Ca/Mg의 경우, 평균 10.97${\pm}$2.40(0 ${\sim}$5개월), 12.87${\pm}$1.52(6${\sim}$ll개월), Ca/Fe의 경우, 평균 64.90${\pm}$9.98(0${\sim}$5개월), 80.10${\pm}$13.79(6${\sim}$ll개월)의 비운을 나타내었다. Na/K의 경우, 평균0.3${\pm}$0.1(0${\sim}$5개월)이며 6${\sim}$ll개월용의 경우 0.3으로 일관적인비율로 함유되었다. Zn/cu의 경우, 평균 9.58${\pm}$1.04(0${\sim}$5개월), 9.44${\pm}$1.05 6${\sim}$ll개월)으로 개월에 관계없이 전반적으로 유사한 비율을 나타내었다.
