Abstract

The salinity of soups of institutions enrolled at the Center for Children's Foodservice Management was monitored to reduce sodium intake of children by continuously managing salinity of soups provided by children food service. Monitoring of salinity was conducted by a salinity meter (SB-1500H, HM digital) three times in 2016 by patrolling children's institutions for the instruction of public health. The average salinity of soups provided by total children's institution showed a significant decrease in salinity - $1^{st}$ 0.45%, $2^{nd}$ 0.41% and $3^{rd}$ 0.39% - as monitoring was proceeded (p<0.01). When salinity of soups was analyzed according to the type of children's institution, the salinity of national and public institutions showed no significant decrease. In contrast, the salinity of private institutions decreased significantly (p<0.05). Depending on the enrollment of the food service, there was no significant difference in average salinity of soups between large food services, which have over 50 children, and small food services, which have less than 50 children. However, all food services showed a salinity decrease from the $1^{st}$ monitoring to the $3^{rd}$ monitoring. Salinity according to the type of soup showed that salinity of clear soup, miso soup, and stew except beef soup decreased from the $1^{st}$ monitoring to $3^{rd}$ monitoring. However, there was no significant difference in salinity according to the type of soup which can be attributed to a large difference in salinity among the same type of soup. The individual soup showing the biggest difference between maximum and minimum salinity of soup was egg soup (0.62%), potato soup (0.54%), and mushroom soup (0.64%). The present average salinity of soup provided by children's institutions was less than 0.5% which is the recommended standard of the Ministry of Food and Drug Safety. However, the salinity of soups should be managed within a certain range including the minimum salinity regarding the taste education of children.

본 연구는 지속적인 염도 관리의 교육효과를 살펴보기 위하여 강동구 어린이급식관리지원센터에 등록된 21인 이상의 어린이집에서 제공되는 국물음식의 염도를 모니터링 하였으며, 그 결과는 아래와 같다. 1. 모니터링을 실시한 시설은 1차 102개소, 2차 76개소, 3차 78개소이며, 맑은 장국, 된장국, 곰국, 찌개, 기타로 구분한 국물음식의 평균 염도는 1차(0.45%), 2차(0.41%), 3차(0.39%)로 진행됨에 따라 유의적으로 감소하였다(p<0.01). 2. 어린이집 유형에 따른 염도는 국공립어린이집의 경우, 1차 0.43%, 2차 0.35%, 3차 0.38%로 유의적인 감소를 나타내지는 않았으나, 민간어린이집은 1차 0.46%, 2차 0.43%, 3차 0.39%로 모니터링을 진행할수록 유의적으로 감소하였다 (p<0.01). 3. 집단급식소 등록 여부에 따라 급식 인원 50인 이상의 대규모 급식소와 50인 미만의 소규모 급식소의 염도를 비교한 결과, 대규모 급식소의 국물음식의 평균 염도가 낮았으나 유의적인 차이를 보이지 않았으며, 모두 1차에 비해 3차의 평균 염도가 감소하는 경향을 나타냈다. 4. 3차에 걸친 모니터링 시 어린이집에서 제공한 국물음식의 횟수는 총 256회였으며, 이 중 맑은 장국이 139회로 가장 많이 제공되었고, 된장국이 76회, 기타(들깻국, 수제비 등) 24회, 찌개 9회, 곰국 8회 순서로 나타났다. 5. 국물음식의 종류별 염도는 곰국을 제외하고는 맑은 장국, 된장국, 찌개 모두 1차에서 3차로 진행될수록 염도가 감소하였으나, 국의 종류 및 모니터링 차수에 따른 염도의 유의적인 차이는 없었다. 그러나 동일한 국물음식 간에도 염도의 차이가 매우 커서 개별 국물음식의 최소치와 최대치의 차이는 1차의 경우 달걀국이 0.62%, 2차는 감잣국이 0.54%, 3차는 양송이국이 0.64%를 나타냈다. 본 연구 결과, 지속적인 염도 모니터링 진행을 통해 어린이집 국물음식의 염도가 낮아지는 것으로 나타나, 센터에서 진행하는 교육의 효과를 확인할 수 있었다. 영유아 급식시설에서의 국물음식의 염도 기준은 명확하게 제시되어 있지 않으나, 식품의약품안전처에서는 성인의 경우 0.6% 이하, 영유아 급식시설에서는 이보다 더 낮은 0.5% 이하로 관리하도록 권고하고 있다. 그러나 적정 염도는 음식의 종류에 따라 다르므로 영유아를 위한 주요 나트륨 급원 메뉴의 적정 염도범위를 설정할 필요가 있다. 또한 본 연구에서 3차에 걸쳐 조사된 국물음식의 전체 염도 평균치는 모두 0.5% 미만으로 적절한 범위에서 관리하고 있었으나, 개별 국물음식의 염도는 매우 큰 차이를 나타내었다. 영유아는 미각이 형성되는 시기이며, 염도는 음식에 대한 기호에 영향을 줄 수 있으므로 국물음식의 염도는 일정한 범위 내에서 관리되는 것이 바람직하며, 추후 최고 염도뿐만 아니라, 음식의 맛과 건강을 함께 고려하는 최저 염도에 대한 논의도 함께 이루어져야 할 필요가 있을 것으로 사료된다.
