Abstract
A series of experiment was undertaken to pursue the possibility of aflatoxin accumulation in stored grains which were artificially contaminated with A. flavus var. columnaris isolated from deteriorated rice in Korea. In storage of rice grain, aflatoxin formation needed relative humidity over 80%, once accumulated aflatoxin was degraded by other microbial growth maintaining 50% level and the absence of other microoganisms brought about the remarkable accumulation of aflatoxin. The formation of aflatoxin in grains was increasing in the order of soybean, peanut, corn, wheat, barley, foxtail millet, rice, polished wheat, mung bean and great millet and it appears to be affected by the size and oil content of grains.
국내(國內)의 변질미(變質米)에서 분리된 A. flavus var. columnaris가 저장곡류(貯藏穀類)에 오염(汚染)되었을 때 aflatoxin 생성(生成)에 의한 위험가능성(危險可能性)을 추구(追究)하기 위하여 일련의 실험이 수행되었다. 그 결과 쌀 저장중 aflatoxin의 생성에는 80%이상의 상대습도(相對濕度)가 요구되었고 일단 축적된 aflatoxin은 다른 미생물의 번식에 의하여 분해되어 50% 수준을 유지하였으며 다른 미생물이 공존하지 않는 경우는 aflatoxin의 대량축적이 일어났다. 곡류(穀類)에서의 aflatoxin생성량은 대두(大豆), 땅콩, 옥수수, 밀, 보리, 조, 쌀, 밀쌀, 녹두, 수수의 순서로 증가하였으며 곡립(穀粒)의 크기와 유지(油脂)의 함량에 영향되는 경향을 보여 주었다.
