An onion extract is concentrated at low temperature under reduce pressure to 18 to 22 Brix% and is mixed with maltodextrin with a polymerization degree of 8 to 10 to be 35 to 45% by weight of a solid content of the onion extract and 55 to 65% by weight of maltodextrin. The mixture is sprayed with the same amount of distilled water and dried at an intake temperature of 170 to 190deg.C, a chamber temperature of 100 to 110deg.C and an exhaust temperature of 95 to 100deg.C. Then, 87 to 93% by weight of the obtained onion powder is mixed with 0.5 to 1.5% by weight of a lubricating agent, 0.5 to 1.5% by weight of vitamin C, 3 to 5% by weight of apple juice powder and 3 to 5% by weight of orange juice powder and is tableted.
