In the first invention of the present application, cellulase, pectinase and phospholipase are used in combination as enzymes for decomposing tea leaves in the presence of water. Cellulase and pectinase are mainly involved in the decomposition of cell walls, and phospholipase is mainly involved in the decomposition of biological membranes, thereby increasing the extraction rate of vitamins such as vitamins C and E, and increasing the yield of green components such as chlorophyll. It is assumed that this increases the The amounts of water and enzymes used vary depending on various conditions, but are usually 100 parts by weight of tea leaves (hereinafter simply referred to as "parts").
For that, about 500 to 2000 parts of water and 0.0 parts of cellulase.
About 1 to 10 parts, about 0.01 to 10 parts of pectinase,
The amount of phospholipase is preferably about 0.01 to 1.0 parts.

It is within a range of about 20 minutes. During the treatment, stirring is not an essential requirement, but may be performed if necessary in order to shorten the treatment time, improve the extraction rate, etc. The treatment is preferably carried out anaerobically in the presence of an inert gas to prevent oxidation of the product. Inert gases include carbon dioxide gas,
Examples include nitrogen gas, and these gases are used either by being blown into the reaction system or by replacing the atmosphere in the reaction vessel.

The second invention of the present application is almost the same as the first invention of the present application except that protopectinase and protease are used together as enzymes. Protopectinase breaks down protopectin, etc. that bind tea leaf cells, isolates individual cells, and improves the extraction rate. In addition, protease decomposes proteins in tea leaves to generate amino acids, and the flavor of the amino acids serves to reduce bitterness, astringency, etc. of the extract. The amounts of water and enzymes used vary depending on various conditions, but usually for 100 parts of tea leaves,
Approximately 500 to 2000 parts of water, 0.0 parts of protopectinase
It is preferable to use about 15 to 15 parts of protease and about 0.015 to 15 parts of protease.
