Abstract
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.
