Abstract

This study was carried out to investigate the contents of minerals and heavy metals in the sea salts of Korean products and imported products. NaCl was major component, which ranged from $80.31{\sim}89.84%$ for Korean products and from $91.59{\sim}97.66%$ for imported products. Minerals and heavy metals of Korean products and imported products were analyzed with ICP-AES and AAS, respectively. Mineral contents of K and Mg in Korean products were relatively higher than those in imported ones, but no significant differences were found for heavy metals between them.

총 11종 소금의 식염함량은 국내산 천일염의 경우 $80.31{\sim}89.84%$, 수입산 천일염은 $91.59{\sim}97.66%$로 나타났다. 불용성분은 국내산 천일염이 $0.01{\sim}1.24%$, 수입산 천일염이 $0.06{\sim}0.89%$를 나타냈고, 황산이온함량은 $0.21{\sim}0.55%$, 수입산 천일염은 $0.18{\sim}0.31%$로 나타났다. 국내산 천일염 중 수입산에 비해 상대적으로 높게 함유된 무기질은 K 그리고 Mg이었으며 국내산과 수입산에 비슷한 수준으로 존재하는 것은 Ca이었다. Mn은 극미량 검출되었고, Cu는 수입산에서 상대적으로 높게 검출되었으며 Ge은 국내산에서 대체적으로 높게 나타났다. 국내산 및 수입산 천일염의 중금속(Pb, Cd, As 그리고 Hg)함량은 식품위생법 규정의 기준치 이하로 나타났다.
