【摘要】 报道了四川省部分地区玉米、小麦、大米３种主要粮食中霉菌侵染状况和伏马菌素Ｂ_１（ＦＢ_１）、杂色曲霉素（ＳＴ）、烟曲霉震颤素（ＦＴ）３种霉菌毒素的污染状况。结果显示３种粮食中霉菌侵染严重，其侵染率分别为９２．３％、８７．２％、７２．４％。菌相以曲霉菌为主，同时检出了产生ＳＴ毒素的杂色曲霉菌。ＦＢ１和ＳＴ在粮食中污染较普遍，ＦＢ_１检出率为１２．８％～１００％，含量１５．２～２７．０ｍｇ／ｎｇ；ＳＴ检出率为３４．３％～５６．９％，含量２４．０～７５．０μｇ／ｋｇ。ＦＴ在粮食中污染率和含量均较低。更多还原

【Abstract】 This article reports the invasion of fungi and contamination of Fumonisin B1 (FB1), Sterigmatocysin(ST), Fumitremorgins (FT) in maize, wheat and rice in some areas of Sichuan province. The results shawed thatfungus invasion was serious in the grains, the invasion rates are 92.3%, 87.2% and 72.4% respectively. Most fungiare aspergillin, A. which produces ST is detected. The contaminatiion of FB1 and ST in grains are relatively popular,the detective rate is 12.8%-100% with the content of 15.2-27.0mg/kg, and 34.3%-56.9% with the content of24.0-75.0μg/kg respectively. The contamination rate and content of FT in grains are low.更多还原
