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.

First claim

The invention claimed is:

1. A method for preparing aged tea water, comprising:
deactivating enzymes of raw tea leaves by subjecting the raw tea leaves to steaming, and extracting juice therefrom to obtain tea juice, wherein the raw tea leaves are non-processed tea leaves;
removing ions from the tea juice to obtain tea water; and
aging the tea water at 0-120° C. for 12-24 hours,
wherein the aged tea water comprises; linalool in an amount of 5 μg/mL or less; hexanol in an amount of 0.2 μg/mL or less; and/or z-3-hexenol an amount of 0.2 μg/mL or less.

2. 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 to provide the tea water.

3. The method according to claim 1 , wherein the step of aging the tea water occurs at 40-80° C. for 12-24 hours.

4. The method according to claim 1 , wherein the step of aging the tea water occurs at 4-40° C. for 12-24 hours.

5. The method according to claim 1 , wherein the step of aging the tea water occurs under pressure.
