The method employed was similar to the way of tea preparation a consumer might also use. The two samples used for this experiment were a black tea (Darjeeling first flush-FTGFOP1) and a green tea (Chun Mee). The content of individual and total amino acids was determined after brewing times of 0.5, 1, 1.5, 2, 3, 4 and 5 min without application of agitation and with leaf/water ratio of 10 g/L.
