Abstract

A survey of aflatoxin $B_1$ and ochratoxin A was conducted on dried red pepper and red pepper powder. Total number of 193 samples were collected from local markets in Incheon. The presence of aflatoxin $B_1$ and ochratoxin A was determined by high performance liquid chromatography (HPLC) with fluorescence detector using immunoaffinity column clean-up. The recovery rate of aflatoxin $B_1$ and ochratoxin A were more than 80% and the limits of quantification were 0.13 ${\mu}g/kg$ for aflatoxin $B_1$ and 0.30 ${\mu}g/kg$ for ochratoxin A. Aflatoxin $B_1$ was detected in 33 samples (17.1%) with a range of 0.14~9.67 ${\mu}g/kg$ and ochratoxin A was detected in 40 samples (20.7%) with a range of 0.31~3.31 ${\mu}g/kg$. These results show that the occurrence of aflatoxin $B_1$ and ochratoxin A in dried red pepper and red pepper powder tested in this study is low compared with the standard in Korea Food Code (10 ${\mu}g/kg$ as aflatoxin $B_1$ and 7 ${\mu}g/kg$ as ochratoxin A).

2012년 2월부터 11월까지 인천 지역에서 유통된 건고추 및 고춧가루 193건을 대상으로 아플라톡신 $B_1$과 오크라톡신 A의 오염도를 조사하였다. Immunoaffinity column 및 HPLC를 이용한 시험법은 모두 80% 이상의 회수율을 보였고, 아플라톡신 $B_1$ 및 오크라톡신 A의 검출한계는 각각 0.13 ${\mu}g/kg$, $0.30{\mu}g/kg$였다. 오염도 조사를 한 결과 아플라톡신 $B_1$은 17.1%의 검출율을 보였고 오크라톡신 A는 20.7%의 검출율을 보였으며, 아플라톡신 $B_1$의 검출농도는 0.14~9.67 ${\mu}g/kg$였고, 오크라톡신 A의 검출 농도는 0.31~3.31 ${\mu}g/kg$였다. 이는 우리나라 식품공전 상의 기준인 10 ${\mu}g/kg$(아플라톡신 $B_1$), 7 ${\mu}g/kg$(오크라톡신 A)보다는 낮은 수치로 비교적 안전한 수준이었다.
