우리나라는 산업의 발달로 산업 폐기물 및 각종 오염물질들이 해양을 오염시킴에 따라 이들 해양에서 생산된 해양식품에 중금속이 잔류하게 되어 해양식품의 안전성에 대한 사회적 관심이 높아지고 있다. 우리나라에서는 그동안 부분적으로 식품의 오염정도를 검토하고 있으나 식품이 섭취되기까지 여러 단계의 가공을 거치게 되므로 실제 섭취량은 식품 중 잔류 중금속 양과 다를 수 있다. 따라서 본 연구에서는 해양식품 중 가공 단계를 거치는 젓갈 7종을 산지에서 수거하여 동결건조 후 영양학적 면과 더불어 중금속 함량을 함께 고찰하고자 Fe, Cu, Zn, Cr, Co, Mn, Pb와 Cd 등의 미량무기질 함량을 분석하였는데, 7종(새우젓, 조개젓, 어리굴젓, 밴댕이젓, 곤쟁이젓, 황석어젓, 한치젓)의 젓갈의 수분 함량은 각각 68.3, 71.5, 81.1, 62.2, 71.3, 64.2, 66.74% 이었고, 철분함량은 각각 66.46, 309.10, 27.03, 23.01, 132.45, 35.75, 9.72ppm이었으며, 구리함량은 각각 4.60ppm, 4.36ppm, 3.75ppm, 2.21ppm, 10.36ppm, 2.71ppm, 58.15ppm이었으며, 아연함량은 각각 16.02ppm, 75.06ppm, 37.43ppm, 28.43ppm, 132.45ppm, 35.75ppm, 9.72ppm이었다. 그리고 크롬함량은 각각 0.80ppm, 1.61ppm, 0.84ppm, 0.96ppm, 1.12ppm, 0.96ppm, 0.59ppm이었고, 코발트함량은 각각 0.13ppm, 0.54ppm, 0.31ppm, 0.46ppm, 0.50ppm, 0.63ppm, 0.35ppm이었으며, 망간함량은 각각 7.30ppm, 10.69ppm, 14.87ppm, 4.12ppm, 8.03ppm, 2.94ppm, 1.54ppm이었다. 그리고 7종의 젓갈의 납함량은 각각 1.80ppm, 4.30ppm, 2.53ppm, 4.61ppm, 3.08ppm, 5.04ppm, 2.74ppm이었으며, 카드뮴함량은 각각 0.005ppm, 0.03ppm, 0.06ppm, 0.005ppm, 0.01ppm, 0.00ppm, 0.10ppm이었다.
This study was performed to assess the levels of the trace elements(Fe, Cu, Zn, Cr, Co, Mn, Pb, and Cd) in salt-fermented fish products from some areas of the west coast in Korea. Seven samples were Shrimp(Seawoo-jeot), Clam(Jogai-jeot), Oyster(Orikul-jeot), big eyed horring(Bendeng-ie jeot), Mysis(Gonjeng-ie jeot), Hwangandali(Hwangsegi-jeot), and Squid, Han Chi(Han chi-jeot). They were ashed with ternary solution. After ashing the samples, the amount of trace elements in the samples were measured by ICP. The moisture content of the 7 samples before freezing dry were 68.36, 71.52, 81.19, 62.27, 71.30, 64.27, and 66.74%, respectively. Jogai-jeot and Gonjeng-ie jeot contained the most amount of moisture among the samples. Fe contents were 66.46, 309.10, 27.03, 23.01, 132.45, 35.75, and 9.72ppm, respectively. Jogai-jeot contained the most amount of Fe among the samples. Cu contents were 4.60, 4.36, 3.75, 2.21, 10.36, 2.71, and 58.15ppm, respectively. Hanchi-jeot contained the most amount of Cu among the samples. Zn contents were 16.02, 75.06, 37.43, 28.43, 132.45, 35.75, and 9.72ppm, respectively. Gonjeng-ie jeot contained the most amount of Zn among the samples. Cr contents were 0.80, 1.61, 0.84, 0.96, 1.12, 0.96, and 0.59ppm, respectively. Jogai-jeot contained the most amount of Cr among the samples. Co contents were 0.13, 0.54, 0.31 0.46, 0.50, 0.63, and 0.35ppm, respectively. Hwangsegi-jeot contained the most amount of Co among the samples. Mn contents were 7.30, 10.69, 14.87, 4.12, 8.03, 2.94 and 1.54ppm, respectively. Origkul-jeot contained the most amount of Mn among the samples. Pb contents were 1.80, 4.30, 2.53, 4.61, 3.08, 5.04, and 2.74ppm, respectively. Hwangsegi-jeot contained the most amount of Pb among the samples. Cd contents were 0.005, 0.03, 0.06, 0.005, 0.01, 0.00, and 0.10ppm, respectively. Hanchi-jeot contained the most amount of Cd among the samples. This study is limited within 7 samples caught and producted from the some areas of the west coast in Korea. Therefore, I hope there will be broader experiments concerned with this study to make clear not only nutritional aspect(the contents of Fe, Cu, Zn, Cr, Co, and Mn) but also toxicological aspect (the contents of Pb and Cd).
