The aim of this investigation was to determine the effect of green tea additive on the yield of obtaining the concentrated extracts of tea and on quality of tea beverages prepared on the basis of resultant concentrates and fruit powders. When used for extraction the black and green tea mixtures in proportion 2:1 the obtained yield reached 60%. Solubility of products obtained in experiments ranged from 72% to 91% while solubility of commercial products was 65% and 95%, respectively. It was found that there is a relation between solubility and pH of tea beverage (correlation coefficient – 0.632). The green tea additive had beneficial effect on the clarity of tea beverages and caused that yield of process decreased insignificantly. Moreover, the fruit powder additive masked the green tea flavour efficiently.
