ABSTRACT

Five different popular marketed brands of tea produced in Bangladesh viz; Tetley-Premium, Lipton-Taaza, Finlay-Premium, HRC-Clevedon, Ispahani-Blender's choice were studied before expiry dates to evaluate their status of qualitative parameters viz; Caffeine, Total Polyphenol Content (TPC), Theaflavin (TF), Thearubigin (TR), Highly Polymerized Substances (HPS), Total Liquor Colour (TLC), Briskness Index (BI) and Colour Index (CI). All the studied parameters were found to have been varied with brands. The values of caffeine and TPC were found to be varied from 2.65% (Finlay-Premium) to 3.28% (Tetley-Premium) and 24.58% (Lipton-Taaza) to 12.76% (Tetley-Premium) respectively. Similarly, the estimated values of TF, TR and TLC were detected to be maximum in Lipton-Taaza tea but maximum HPS was in Finlay-Premium tea whereas minimum TF and TLC was in Tetley-Premium tea and minimum TR and HPS was in HRC-Clevedon tea. In contrast, BI and Cl were found to be the highest in Ispahani-Blender's choice and HRC-Clevedon tea respectively and the lowest in Tetley-Premium tea. The present study concludes that the Lipton-Taaza tea is superior over the other brands in respect to qualitative status and all the studied brands may, therefore, be ranked as: Lipton-Taaza > Finlay-Premium > Ispahani-Blender's choice > HRC-Clevedon > Tetley-premium.
