摘要： This invention is related to a method of manufacturing a tea drink, which comprises the steps of subjecting tea leaves to extraction to obtain an tea extract and adjusting the pH of the tea extract to the range of 5.0-6.0, mixing nitrogen into the tea extract while applying a negative pressure of 0.01 MPa or more, stabilizing the tea extract in succession to the step of applying a negative pressure by maintaining the tea extract under a pressure of not higher than atmospheric pressure for a period of 30 seconds to 20 minutes, and adjusting the pH of the tea extract to the range of 5.5-6.5 during or subsequent to the step of stabilizing the tea extract. According to this invention, it is possible to suppress the loss of aroma during the manufacturing process of tea drink and hence to manufacture a tea drink which is stable in quality and excellent in aroma.
