Insect infestation of agricultural stored products is a significant challenge to food security across the globe. One common pest is (red flour beetle). In a new approach to addressing the threat of these beetles, Direct Analysis in Real Time-High-Resolution Mass Spectrometry was used to examine infested and uninfested flour samples. These samples were then distinguished through statistical analysis techniques, including EDR-MCR, in order to highlight the important / values contributing to the differences in the flour profiles. A subset of these values responsible for the identification of infested flour (nominal / 135, 136, 137, 163, 211, 279, 280, 283, 295, 297, and 338) were further investigated, and compounds responsible for these masses included 2-(2-ethoxyethoxy)ethanol, 2-ethyl-1,4-benzoquinone, palmitic acid, linolenic acid and oleic acid. These results have the potential to lead to a rapid technique by which flour and other grains can be tested for insect infestation.
农业储存产品的虫害是全球粮食安全的重大挑战。一种常见的害虫是（赤拟谷盗）。在一种解决这些甲虫威胁的新方法中，直接实时分析-高分辨率质谱法被用于检查受感染和未受感染的面粉样本。然后，通过包括 EDR-MCR 在内的统计分析技术对这些样本进行区分，以突出对面粉图谱差异有贡献的重要/有价值的因素。一小部分负责识别受感染面粉的数值（标称值/135、136、137、163、211、279、280、283、295、297 和 338）被进一步研究，负责这些质量的化合物包括 2-(2-乙氧基乙氧基)乙醇、2-乙基-1,4-苯醌、棕榈酸、亚麻酸和油酸。这些结果有可能导致一种快速的技术，通过该技术可以测试面粉和其他谷物是否受到虫害。
