초록

본 실험은 우리나라에서 생산되고 있는 시판 햄 26종과 소시지 30종을 구입하여 NA 함량을 GC-TEA로 분석하였고, 동시에 NA 생성에 영향을 미칠 것으로 판단되는 질산염 및 아질산염도 분석하였다. 시판햄의 질산염 및 아질산염 질소는 각각 1.2~16.6 mg/kg 및 0.6~2.3 mg/kg의 범위였으며, 소시지는 각각 0.1~21.1 mg/kg 및 0.1~7.8 mg/kg으로 아질산염 질소가 질산염질소에 비해 낮게 정량되었다. 대부분의 시판햄 및 소시지에서 NDMA가 검출되었으며, 햄의 경우 단일햄 및 혼합햄이 각각 $<0.5~61.5\;\mu\textrm{g}/kg\;및\;<0.5~12.5\;\mu\textrm{g}/kg$이었고, 단일소시지 및 혼합소시지가 각각 $0.5~36.8\;\mu\textrm{g}/kg\;및\;<0.5~61.5\;\mu\textrm{g}/kg$이었다. 햄보다 소시지에서 질산염 및 아질산염 함량이 높게 정량되었고 NDMA 함량은 혼합소시지에서 가장 높게 검출되었다.

This experiment was conducted to study occurrence of N-nitrosamine (NA) and its precursors such as nitrate and nitrite. For the experimental samples, 26 kinds of commercial hams and 30 kinds of sausages produced in Korea were purchased. The nitrate and nitrite were positive in all of the collected samples; nitrate levels were by average 4.4~9.2 mg/kg and nitrite ones were by average 1.3~3.6 mg/kg. The contents of nitrate and nitrite were detected higher in sausage than in ham. Especially, nitrate contents were contained higher in lyoner sausage prepared with the mixture of meat and fish, while nitrite contents were contained higher in the meat only mixture. N-nitrosodimethylamine (NDMA) among the analyzed 7 kinds of NA was detected only in ham and sausage; its contents were outstanding in lyoner sausage which was prepared with only meat and pork sausage, and then regular ham was the next one in its order, but its contants were detected by average $<0.5\;\mu\textrm{g}/kg$ in press hams added vegetable.
