Barley fusarium graminearum pollution distinguishing method based on GC-IMS

The invention discloses a barley fusarium graminearum pollution distinguishing method based on GC-IMS, and belongs to the technical field of rapid analysis and detection. The method comprises the following steps: performing GC-IMS detection on a barley sample, and if a migration spectrum characteristic peak of a marker exists in a GC-IMS spectrogram of the barley sample, judging whether the barley sample is polluted by fusarium graminearum or not according to the migration spectrum characteristic peak of the marker. According to the method, the GC-IMS technology is combined with the migration spectrum characteristic peak of the marker, so that the technical defects of high equipment cost, complicated operation process and the like for detecting the stored barley polluted by fusarium graminearum are overcome, and the convenient and rapid detection effect is achieved. 本发明公开了基于GC-IMS的大麦禾谷镰刀菌污染判别方法，属于快速分析检测技术领域。所述方法包括：对大麦样品进行GC-IMS检测，若大麦样品的GC-IMS谱图中存在标记物的迁移谱特征峰，则根据所述标记物的迁移谱特征峰，判定大麦样品是否被禾谷镰刀菌污染。本发明通过GC-IMS技术结合标记物的
