Variation Analysis of Food- Three Dimensional Fluorescence Spectra of Black Tea Leaves with Different Places of Origin -

There are concerns in the food industry about food safety and security, including contamination and foods that disguise their true place of origin. Confirming the place of origin of branded goods and imported goods is sometimes impossible based on visual analysis and simple testing alone, and with the introduction of the Trans-Pacific Partnership (TPP) the number of these goods is going to increase. Three dimensional (3D) fluorescence analysis represents the fluorescent characteristics of a substance as a spectral map. 3D fluorescence spectra and analysis of these spectra promises to be able to distinguish between different material types and places of origin. We describe using the RF-6000 spectrofluorophotometer to obtain 3D spectra for black tea leaves from different places of origin, and attempting to distinguish between different places of origin by performing multivariate analysis of these results.
