本研究调查了储存六个月的小麦籽粒和面粉中脱氧雪腐镰刀菌烯醇（DON）及其衍生物（deoxynivalenol-3-glucoside (D3G), 15-acetyldeoxynivalenol (15-AcDON) 和3-acetyldeoxynivalenol (3-AcDON)）的情况。将受DON, D3G, 15-AcDON和3-AcDON污染的小麦籽粒与面粉包装在聚乙烯袋、牛皮纸袋和布袋中，在常温和4-6℃条件下储存，分别在储存了30、90和180天后利用UPLC-MS/MS方法分析其霉菌毒素水平。研究结果表明，在小麦籽粒和面粉储存过程中会发生DON及其衍生物转化。
外文摘要：
Fate of deoxynivalenol (DON) and its derivatives deoxynivalenol-3-glucoside (D3G), 15-acetyldeoxynivalenol (15-AcDON) and 3-acetyldeoxynivalenol (3-AcDON) during six-month storage of wheat grain and flour was investigated. Wheat grain and flour polluted by DON, D3G, 15-AcDON and 3-AcDON were packaged in polyethylene bags, kraft paper bags and cloth bags, and stored at room temperature and 4-6 degrees C, and mycotoxin levels were analyzed by UPLC-MS/MS after storing for 30, 90 and 180 days. Levels of DON, 15-AcDON and 3-AcDON in wheat grain showed a generally decrease during the storage duration, and DON concentrations averagely decreased by 40-50%. An obviously increase of DON (more than 70%) and decrease of 15-AcDON and 3-AcDON were observed after storage in wheat flour. There were no significant differences of D3G levels in most of wheat grain and wheat flour samples after storage, but some increased dramatically with retention level up to 240%. The results suggested conversion of DON and its derivatives may occur during wheat grain and flour storage.
