The Detection of Aflatoxin in Home-made Takju and Peanut butter

충청북도 청원군 9개면에서 수집한 자가탁주 시료와 청주지역 시장에서 수집한 국내산 땅콩버터중의 aflatoxins 검색 결과 다음의 결론을 얻었다. 1. 자가탁주 시료에서는 78% 이상의 지역 시료에서 aflatoxin B1이 검출되었으며 평균 0.36 ppb, 최고 1.2 ppb까지 검출되었다. 2. 국내산 땅콩버터 시료에서는 aflatoxin류가 검출되지 않았다. 3. Sep-Pak silica cartridge에 의한 정제법은 기존의 column chromatography 정제법보다 회수율, 시간, 시약 등에서 훨씬 더 효율적이었다.

ABSTRACT-In order to detect the aflatoxins in home-made Takju and peanut butter, the samples were collected in Chungbuk region and cleaned up Sep-pak silica cartridge. Aflatoxins were detected by thin layer chromatographic and high performance liquid chromatographic behavior. Determination was carried out by thin layer densitometer. The results were as follows; 1. Aflatoxin B, was detected in 78% of the home-made Takju, and the highest concentration was 1.2 ppb and average 0.36 ppb. 2. Aflatoxins were not detected in any peanut butter smaples. 3. Clean-up method by Sep-pak silica cartridge was more efficient and economical than column chromatography of AOAC method.method.
