Participants

Reaction Steps

1 g of the UHA4002 and 0.2 g of the UHA4003 obtained by the method of Example 8 were dissolved in 10 mL of ethanol, 20 g of taurine, 0.12 g of vitamin B1 nitrate, 0.6 g of sodium benzoate, 4 g of citric acid, 60 g of sugar, and 10 g of polyvinyl pyrrolidone were all dissolved in purified water, and then the solution was diluted in a measuring cylinder to 1000 ml. The pH was adjusted to 3.2 using dilute hydrochloric acid. 50 ml of 1000 ml of the obtained solution was charged into a glass bottle, and then sterilized at 80° C. for 30 minutes, thereby completing a drink agent which is a quasi drug. The drink agent can be effectively utilized as a quasi drug aiming at reducing the risk of infectious diseases in addition to the purpose of supply of nutrients.
