The feasible screening of genuine fresh palmyrah toddy and sugar or rice toddy using near-infrared spectroscopy

Abstract

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.
