The effect of gamma-irradiation on fumonisin B1 (FB1) and fumonisin B2 (FB2) occurring in maize materials has been investigated together with the stability of fumonisins in gamma-irradiated maize stored at different temperatures (-18 to +40 degrees C) for different periods (2, 4, 13 and 26 weeks). Fifteen KGy gamma-irradiation was required to sterilize efficiently maize flour. This process caused a decrease in fumonisin content of about 20%. The stability studies showed that fumonisins are stable in gamma-irradiated maize for at least 6 months at 25 degrees C or at least 4 weeks at 40 degrees C. These data indicate that gamma-irradiation is an appropriate technique for obtaining sterilized maize materials to be used for intercomparison studies on analytical procedures for the measurement of the fumonisin content.
研究了γ射线辐照对玉米材料中伏马菌素B1（FB1）和伏马菌素B2（FB2）的影响，以及在不同温度（-18至+40摄氏度）下储存不同时间（2、4、13和26周）的γ射线辐照玉米中伏马菌素的稳定性。高效灭菌玉米粉需要15千戈瑞的γ射线辐照。此过程使伏马菌素含量降低了约20%。稳定性研究表明，伏马菌素在25摄氏度下的γ射线辐照玉米中至少6个月稳定，在40摄氏度下至少4周稳定。这些数据表明，γ射线辐照是获得用于伏马菌素含量测量分析程序比对研究的灭菌玉米材料的合适技术。
