The use of combination of Near-Infrared (NIR) absorption spectroscopic and k-mean multivariant statical cluster analysis as a screening tools for genuine fresh palmyrah toddy(G.F) and sugar (ATS) or rice toddy(ATS) is discussed. The quick and simple screening methods to ensure the authenticity of G.F is prime important to keep up its commercial value. Here we performed NIR spectroscopic analysis, k-mean multivariant analysis, and hierarchical cluster analysis to screen the G.F from ATR and ATS. For comparison, we performed chemical analysis and distinguished G.F from ATR and ATS. However, based on the NIR spectroscopic analysis together with the multivariant analysis G.F quickly screened from ATR and ATS. The plot of k-means cluster analysis and hierarchical cluster analysis shows three distinct clusters and it could be a useful tool to quickly screen the genuine toddy from artificial toddy.
讨论了使用近红外（NIR）吸收光谱法和k均值多变量统计聚类分析相结合作为筛选真正新鲜棕榈酒（G.F）以及糖（ATS）或米酒（ATS）的工具。确保G.F真实性的快速简单筛选方法对于维持其商业价值至关重要。在此，我们进行了近红外光谱分析、k均值多变量分析和层次聚类分析，以从ATR和ATS中筛选出G.F。为作比较，我们进行了化学分析并区分了G.F与ATR和ATS。然而，基于近红外光谱分析和多变量分析，能快速从ATR和ATS中筛选出G.F。k均值聚类分析和层次聚类分析的图显示出三个不同的聚类，它可能是从人工酒中快速筛选出真正棕榈酒的有用工具。
