Abstract

This study was carried out to survey the contents of mineral and heavy metal of the commercial salt and salted-fermented shrimp. Mineral and heavy metal contents of Korean products and imported salts, and their effects on shrimps were analyzed through ICP-AES/MS. K and Mg contents of Korean salts and salted-fermented shrimp were relatively higher than those imported ones, However, no significant differences were found for mineral of commercial salted-fermented shrimps between Korean products and imported ones. Heavy metal contents of commercial salts lower than the maximum permissible limit set by KFDA. As, HB, and Ni were not detected in both commercial and lab-made salted-fermented shrimps. Cd were detected ranges of ND-0.5 ppm (average 0.1ppm) for commercial salted-fermented shrimps. Pb were detected ranges of ND-0.8ppm(average 0.28ppm) for lab-made salted-fermented shrimps.

국내산 소금과 수입산 소금의 무기질 및 중금속 함량의 차이와 이들 소금이 새우젓의 무기질 및 중금속 함량에 미치는 영향을 파악하였으며, 실제 시판되고 있는 새우젓을 산지별로 구입하여 무기질 및 중금속 함량을 분석하였다. 국산 천일염과 그것으로 제조한 새우젓은 중국산에 비해 Cu, K, Mg의 함량이 많았으며, 중국산 천일염과 그것으로 제조한 새우젓은 Mn, Na함량이 높은 것으로 나타났다. 그러나 시판새우젓에서는 산지에 따른 무기질의 차이가 나타나지 않았다. 중금속을 분석한 결과 시판 소금은 Pb, Hg 및 As는 검출되지 않았으나, Cd는 식품공전의 규정(<0.5ppm) 이하인 0.07-0.30ppm의 함량으로 검출되었다. 20 종의 시판 새우젓의 경우, Cd가 0.1 ppm(ND-0.5 ppm)의 함량으로 검출되었으며, 실험실 제조 새우젓의 경우, Pb이 0.3ppm(ND-0.8ppm)의 함량으로 검출되었으며, 다른 중금속(As, Hg, and Ni)은 검출되지 않았다.
