For brewers, it is important to know the geographic origins of the hop plants (Humulus lupulus L.) used in their brewing processes since the contents and compositions of the bitter resins and essential oils in them depend on the environmental conditions during their growth. In this study, the multi-elemental profiles of hop plants from each of the world's main growing regions were determined by non-destructive energy dispersive X-ray fluorescence spectrometry (EDXRF). Understanding the multi-element profiles of the plants could be a useful tool in determining the geographic origins of produced hop plants.
对于啤酒酿造商来说，了解其酿造过程中使用的啤酒花（Humulus lupulus L.）的地理来源非常重要，因为它们的苦味树脂和精油的含量和组成取决于其生长过程中的环境条件。在这项研究中，采用非破坏性能量色散 X 射线荧光光谱法（EDXRF）测定了来自世界主要种植地区的每个啤酒花植物的多元素图谱。了解植物的多元素图谱可以成为确定生产的啤酒花植物地理来源的有用工具。
