The extracting conditions of lotus leaf, the optimal formula and stability of tea milk of lotus leaf was studied through orthogonal analysis. The results showed that the optimal extracting conditions of lotus leaf were as follows: ratio of solid to liquid 30, extracting temperature 80 ℃,extracting time 20 min; the optimal formula was obtained by using 4 % milk,2 % honey and 40 % solution of lotus leaf ; the optimal stabilizer was combinat...
