Abstract
AbstractBlack teas manufactured in Darjeeling and Assam were analysed for various macrominerals such as P, K, Ca, Mg and microminerals such as Mn, Fe and Cu. A considerable amount of minerals, eg K (40‐46 mg), Mg (2.7‐3.0 mg), Ca (0.48‐0.66 mg) and traces of Mn (0.28‐0.40 mg), Fe (0.16‐0.20 mg), P (29‐41 μg) and Cu (12‐22 μg) were found in a cup of black tea brew. Black teas manufactured from the leaf coming from a pruned section and fine portion usually showed higher mineral content than tea manufactured from unpruned sections and coarse grade teas of Darjeeling. Assam CTC tea was found to be richer in mineral content compared to Darjeeling orthodox tea.
