Preparation method of tea water, and tea water obtained thereby

Abstract

The present invention provides a preparation method of tea water comprising the following steps of: inactivating enzymes of raw tea leaves and juicing the tea leaves to obtain a tea juice; and removing ions of the tea juice obtained from the previous step to obtain tea water. In addition, the present invention provides tea water obtained by removing ions from a tea juice of raw tea leaves of which enzymes are inactivated. Skin-stimulating components are reduced in the tea water.

1 . A method for preparing tea water, comprising:
 deactivating enzymes of raw tea leaves and extracting juice therefrom to obtain tea juice; and   removing ions from the tea juice to obtain tea water.   
     
     
         2 . The method according to  claim 1 , wherein the enzymes of the raw tea leaves are deactivated by subjecting the raw tea leaves to steaming, heating or pressurization, when the tea juice is obtained. 
     
     
         3 . The method according to  claim 1 , wherein the ions are removed from the tea juice by subjecting the tea juice to a vaporization and liquefaction process or an osmotic filtering process, when the tea water is obtained. 
     
     
         4 . The method according to  claim 1 , wherein the method further comprises aging the tea water, after the tea water is obtained. 
     
     
         5 . The method according to  claim 1 , wherein the tea water satisfies at least one of the following: a concentration of linalool of 5 μg/mL or less, a concentration of hexanol of 0.2 μg/mL or less, and a concentration of z-3-hexenol of 0.2 μg/mL or less. 
     
     
         6 . Tea water obtained by removing ions from tea juice of raw tea leaves in which enzymes are deactivated. 
     
     
         7 . The tea water according to  claim 6 , wherein the tea water satisfies at least one of the following: a concentration of linalool of 5 μg/mL or less, a concentration of hexanol of 0.2 μg/mL or less, and a concentration of z-3-hexenol of 0.2 μg/mL or less. 
     
     
         8 . The tea water according to  claim 6 , wherein the tea water is an ingredient of a cosmetic composition. 
     
     
         9 . The tea water according to  claim 6 , wherein the tea water is an ingredient of a food composition. 
     
     
         10 . The tea water according to  claim 6 , wherein the tea water is an ingredient of a pharmaceutical composition.
