“…The added amount of the formulation material was set as follows: gelatin (10 g), cornstarch (20 g), sucrose (10 g), EWP (15 g), and total deionized water (250 mL). The variable parameters were as follows: gelatin (i.e., 7,9,11,13,15, and 17 g), cornstarch (i.e., 14,16,18,20,22, and 24 g), sucrose (i.e., 6,8,10,12,14, and 16 g), and EWP (i.e., 9, 11, 13, 15, 17, and 19 g). Then, the formulation parameters were optimized through RSM.…”
