我们应用成像质谱（IMS）来确定γ-氨基丁酸（GABA）的空间分布。我们发现GABA在种子中有一个特定的定位。我们还可视化各种生物分子以及GABA具有更高的空间分辨率比以前的报告。我们的工作表明，IMS可能是一个强大的工具，探索功能性食品的因素，调查的具体分布的营养素在未使用的自然资源，并评估功能性食品的质量。
We applied imaging mass spectrometry (IMS) to determine the spatial distribution of gamma-aminobutyric acid (GABA). We found that GABA had a specific localization in seeds. We also visualized various biomolecules as well as GABA with higher spatial resolution than in the previous report. Our work suggests that IMS might be a powerful tool for exploring functional food factors, investigating the specific distribution of nutrients in unused natural resources, and evaluating the quality of functional foods.
