Chemical Composition and Quality Comparison of Different Branded and Non-brander Black Tea Samples Available in the Local Market of Peshawar

Four different types of branded and six non-branded samples of black tea were purchased from local market of Peshawar and analyzed for their various parameters i.e., moisture %, ash %, water extract %, caffeine %, tannin % and added color, for assessment of their quality. These parameters were then compared with Pakistan Food Standards. Two non-branded samples were found of low quality due to less caffeine and tannin contents, than the standards prescribed by West Pakistan Pure Food Laws and Regulations, 1965. These two samples were also adulterated by the addition of color and found unfit for human consumption. All other branded and non-branded samples were found fit for human consumptions according to West Pakistan Pure Food Laws and Regulations, 1965.
