Abstract
[한글]

본 연구는 2005년 현재 우리나라 6개월 이하 영아의 불소섭취량을 알아보고 그 적절성을 평가하기 위하여 우리나라에서 시판되고 있는 분유 및 분말 이유식의 불소농도를 알아보고자 하였다. 이를 위해 현재 우리나라 제조회사에서 상품화되어 판매되고 있는 0-6개월 영아용 분유 20종과 분말 이유식 8종의 불소함량을 HMDS를 이용한 변형된 미세확산법과 불소 전극봉을 이용하여 알아보았다. 결과는 다음과 같았다.1. 3개월과 6개월 영아용 분유와 6개월 영아용 분말형 이유식에 함유된 불소농도는 각각 0.74± 0.55 ㎍·g-1, 0.76± 0.65 ㎍·g-1, 4.75± 5.71 ㎍·g-1 이었다.2. 3개월과 6개월 영아용 분유와 6개월 영아용 분말형 이유식을 제조상품별 권장 희석방법에 따라 희석하였을 때 희석분유 및 분말이유식의 불소농도는 각각 0.10± 0.09 ㎍·㎖-1, 0.10± 0.08 ㎍·㎖-1., 0.49± 0.66 ㎍·㎖-1 이었다.3. 3개월과 6개월 영아용 분유와 6개월 영아용 분말형 이유식의 일일 불소섭취량은 증류수로 희석하였을 때 0.09± 0.07 ㎎·day-1, 0.10± 0.08 ㎎·day-1, 0.45± 0.62 ㎎·day-1 로 추정되었다. 이를 0.8 ppm의 불화수로 희석하였을 때에는 각각 0.75± 0.08 ㎎·day-1, 0.79± 0.08 ㎎·day-1, 0.83± 0.70 ㎎·day-1 로 추정되었다.4. 우리나라 3개월과 6개월 영아용 분유와 6개월 영아용 분말형 이유식을 통한 체중 당 불소섭취량은 증류수로 희석하였을 때 0.02± 0.01 ㎎·㎏-1·day-1, 0.01± 0.01 ㎎·㎏-1·day-1, 0.06± 0.08 ㎎·㎏-1·day-1 로 추정된다. 이를 0.8 ppm의 불화수로 희석하였을 때 각각 0.13± 0.02 ㎎·㎏-1·day-1, 0.10± 0.01 ㎎·㎏-1·day-1, 0.11± 0.10 ㎎·㎏-1·day-1 로 추정되었다.5. 이상의 결과로 우리나라에서 제조 판매되는 6개월 이하 영아의 분유 및 분말 이유식을 제조사의 권장 방법에 따라 희석하였을 때 희석 분유 및 분말 이유식의 불소농도가 0.3 ppm이상으로 조사된 제품은 3개월 영아용 분유 12제품 중에는 없었고, 6개월 영아용 분유 12종 중 1개 제품이 0.33 ㎍·㎖-1으로 적정 범위를 초과하였다. 또, 6개월 영아용 분말 이유식 8종 중 3종에서 0.3 ppm이상의 불소농도를 갖는 것으로 조사되었는데 각각 2.13 ㎍·㎖-1, 2.02 ㎍·㎖-1, 0.61 ㎍·㎖-1 이었다.6. 체중 당 불소섭취량은 불소가 포함되지 않은 물로 희석할 경우 6개월 분말형 이유식 8종 중 2종에서 각각 0.13 ㎎·㎏-1·day-1, 0.22 ㎎·㎏-1·day-1 으로 체중 당 권장량인 0.05-0.07 ㎎·㎏-1·day-1 을 초과하는 불소를 섭취하게 될 것으로 추정되었다. 이를 0.8 ppm의 불화수로 분유를 희석하는 경우 3개월과 6개월 용 모든 분유에서 체중 당 권장량을 초과하는 불소를 섭취하게 될 것으로 추정되었으며 분말형 이유식 중 4종에서 체중 당 권장량을 초과하는 불소를 섭취하게 될 것으로 추정되었다.본 연구를 통하여 우리나라에서 제조 판매되는 6개월 이하 영아의 분유 및 분말이유식의 불소농도는 대부분 적정범위이지만 일부 이를 초과하는 제품들이 있음이 확인되었다. 따라서 분유 및 분말이유식의 불소농도가 제조과정에서 고려되어야 할 것으로 보인다. 또한 영아의 분유 및 분말 이유식을 희석할 때 불소가 함유되지 않은 물을 이용하는 것이 바람직 할 것이다.



[영문]The purpose of this study was to analyse the fluoride content of Korean infant powdered milk and powdered babyfood, to estimate daily fluoride intake calculated and to evaluate the proper intake amount of fluoride for a 6 month old or younger infant from commercialized powdered milk and babyfood in Korea in 2005. The fluoride concentrations of 20 kinds of commercialized powdered milk and 8 kinds of commercialized powdered babyfood samples were assessed by a modified microdiffusion method and fluoride ion selective electrode.The obtained results were as follow;1. The concentration of fluoride content in powdered milks for 3 month old and 6 month old infant and powdered baby foods for 6 months infant were 0.74± 0.55 ㎍·g-1, 0.76± 0.65 ㎍·g-1 and 4.75± 5.71 ㎍·g-1, respectively.2. The fluoride concentration of powdered milks for 3 month old infant was 0.10± 0.09 ㎍·g-1, fluoride concentration of powdered milks for 6 month old infant was 0.10± 0.08 ㎍·g-1 and fluoride concentration of powdered babyfoods for 6 month old infant was 0.49± 0.66 ㎍·g-1.3. When these baby foods are diluted with distilled water, the estimates of daily fluoride intake were as follows. The estimate of powdered milks for 3 month old infant was 0.09± 0.07 ㎎·day-1, that of powdered milks for 6 month old infant was 0.10± 0.08 ㎎·day-1 and that of powdered babyfood for 6 month old infant was 0.45± 0.62 ㎎·day-1. In case of reconstituting 0.8 ppm fluoride water, the estimates of daily fluoride intake were as follows The estimate of powdered milks for 3 month old infant was 0.75± 0.08 ㎎·day-1, that of powdered milks for 6 month old infant was 0.79± 0.08 ㎎·day-1 and that of powdered baby food for 6 month old infant was 0.83± 0.70 ㎎·day-1.4. In case of reconstituting distilled water, the estimates of daily fluoride intake per weight were as follows. the estimate of powdered milk for 3 month old infant was 0.02± 0.01 ㎎·㎏-1·day-1, that of powered milk for 6 month old infant was 0.01± 0.01 ㎎·㎏-1·day-1 and that of powdered babyfood for 6 month old infant was 0.06± 0.08 ㎎·㎏-1·day-1. In case of reconstituting 0.8 ppm fluoride water, the estimates of daily fluoride intake per weight were as follows. The estimate of powdered milk for 3month old infant was 0.13± 0.02 ㎎·㎏-1·day-1, that of powered milk for 6 month old infant was 0.10± 0.01 ㎎·㎏-1·day-1 and that of powdered babyfood for 6 month old infant was 0.11± 0.10 ㎎·㎏-1·day-1.5. As the results mentioned above, there was no powdered milk out of 12 kinds of powdered milk for 3 month old infant that went over 0.3 ppm fluoride concentration. However, there was one powdered milk for 6 month old infant that went over 0.3 ppm fluoride concentration. In addition, there were 3 out of 8 powdered baby foods for 6 month old infant that went over 0.3 ppm fluoride concentration; which are 2.13 ㎍·㎖-1, 2.02 ㎍·㎖-1, 0.61 ㎍·㎖-1, respectively.6. In case of reconstituting no fluoride water, there were 2 out of 8 powdered babyfoods for 6 month old infant, estimated to exceed the recommendation of daily fluoride intake per weight (0.05-0.07 ㎎·㎏-1·day-1). Their estimates of daily fluoride intake per weight were 0.13 ㎎·㎏-1·day-1 and 0.22 ㎎·㎏-1·day-1. In case of reconstituting 0.8 ppm fluoride water, all powdered milk products were estimated to exceed the recommendation of daily fluoride intake per weight and there were 4 babyfoods for 6 month infant that were estimated to exceed the recommendation of daily fluorid intake per weight.Based on this study, most of powdered milk and babyfood products in Korea contain the appropriate concentration of fluoride, but there were some products that exceeded the recommendations. For this reason, manufacturers should consider the content of fluoride in their manufacturing process. It was desirable to use no fluoride water in diluting powdered milk and baby foods.
