New gravimetric method for determination of total dissolved solids and percentage extraction for coffee-chicory mixture

Coffee-chicory mixture is consumed widely in India and few parts of USA, France. Although chicory is a coffee surrogate, its use is widespread across India, due to ease of brewing along with coffee when south Indian filter is employed. The comparison of beverage brewed from coffee-chicory mixture has hardly attracted any attention from point of view of total dissolved solids (TDS), percentage of extraction (PE)and in general the relative contribution of each to total beverage composition. As suitable methods are not reported for determination of TDS and percentage extraction for brewed beverage from coffee chicory mixture, we herein, report a new method for the determination of TDS and percentage extraction based on gravimetry.
