Abstract
In this study, sorbic acids and benzoic acids frequently used in foods retailed in Korea were monitored and their estimated daily intakes were assessed for a purpose to ensure food additives safety management. The estimated daily intakes were calculated by categorizing the assessment items into the national average, by gender, by age and the high intake ($95^{th}$) groups based on concentrations of preservatives in foods as well as national health and nutrition survey data. The calculations were then compared with the ADI of the JECFA and the possibility of risk to be imposed on the people was examined. The results indicated that the estimated daily average intakes of preservatives were $221.60{\mu}g/kg{\cdot}bw/day$ of sorbic acids and $27.30{\mu}g/kg{\cdot}bw/day$ of benzoic acids. Compared to the ADI, the intake levels were 0.89 and 0.55% respectively, which were in a safe range. The estimated daily intakes of sorbic acids and benzoic acids in the high intake group ($95^{th}$) were $1140.27{\mu}g/kg{\cdot}bw/day$ and $194.95{\mu}g/kg{\cdot}bw/day$, which were 4.56% and 3.90% of the ADI (%) respectively, indicating that the intake levels of sorbic acids and benzoic acids in the high intake group were within a safe range. As for gender difference, the amount of benzoic acids intake was slightly larger in men than in women. However, gender differences were not observed in terms of the intake of sorbic acids. In terms of the levels of intake by age, the rates were found to be in the range of 0.52-2.10% for sorbic acids and 0.15-1.23% for benzoic acids. Therefore, the levels of sorbic acids and benzoic acids intakes were found not to exceed the ADI in all groups, and thus were within the safe ranges.
본 연구는 식품첨가물의 안전관리확보를 위해 국내 식품 중 사용빈도가 높은 소르빈산류 및 안식향산류를 대상으로 모니터링을 한 후 일일추정섭취량을 평가하였다. 일일추정섭취량은 식품 중 보존료의 농도와 국민건강 영양조사 자료를 이용하여 국민평균, 성별 연령별 상위섭취자($95^{th}$) 그룹으로 분류하여 산출하였고, 이를 JECFA에서 제시한 ADI와 비교하여 국민의 섭취 수준을 확인하였다. 그 결과 분석된 보존료의 국민평균 일일추정섭취량은 소르빈산류 $221.60{\mu}g/kg{\cdot}bw/day$, 안식향산류 $27.30{\mu}g/kg{\cdot}bw/day$로 산출되었으며, ADI 대비 각각 0.89, 0.55% 로 섭취수준은 안전한 것으로 확인되었다. 상위섭취자($95^{th}$)의 소르빈산류 일일추정섭취량은 $1140.27{\mu}g/kg{\cdot}bw/day$로 ADI 대비 4.56%, 안식향산류 일일추정섭취량은 $194.95{\mu}g/kg{\cdot}bw/day$로 ADI 대비 3.90% 수준으로 소르빈산류 및 안식향산류의 상위섭취자 섭취수준도 안전한 것으로 평가되었다. 성별에 따른 차이는 안식향산류의 경우 남자가 여자보다 조금 높았으나 소르빈산류는 성별에 따른 차이를 보이지 않았다. 연령별 섭취수준은 소르빈산류 0.52~2.01%, 안식향산류 0.15~1.23% 로 평가되었다. 따라서 모든 그룹에서 소르빈산류 및 안식향산류의 섭취수준은 ADI를 초과하지 않아 안전한 것으로 평가되었다.
