储存对小麦中DON毒素含量的变化规律研究

摘要

The objective of this research was to examine the changes of deoxynivalenol (DON) contents in wheat powder during storage in normal condition. DON contents in wheat powder during ten months storage period were detected and quantified by gas chromatography with electron capture detection. The DON contends had no significant difference during the period in this research.%本研究的目的是调查南京地区含有脱氧雪腐镰刀菌烯醇（Deoxynivaleno,DON,又称致吐毒素）的小麦中常温储存条件下DON毒素浓度的变化情况。采用耦联电子捕获器气谱色谱仪对小麦储存期内面粉中的DON含量逐月进行检测。小麦面粉储存前DON浓度是8.83±1.75 mg/kg,储存期DON毒素平均浓度分别为6.66、7.33、6.08、7.90、5.45、6.56、7.29、8.02、6.82和8.60 mg/kg,结果表明在储存期间小麦面粉中的DON毒素没有明显变化。研究结果揭示了在调查地区常温储存条件下,小麦中的致吐毒素没有发生显著的变化。
