Princy K. G.

Abstract: This research paper attempts an analysis of the content and the various properties of different brands of tea powder marketed in Kerala. Quality parameters like pH, colour absorbance, bulk density, caffeine content, acid content and calcium tannate content was determined and compared for different samples. Each measurement was repeated thrice and the average value is reported. It was found that the aqueous solutions of tea powders are acidic and the caffeine content and colour absorbance is lowest in green tea. Bulk density of the samples varies from 0.258 - 0.614 g/cm3.

Keywords: pH, bulk density, caffeine content, acid content, calcium tannate content
