Method for producing green tea drink

TL;DR: In this article, the authors proposed a method for producing green tea drink, comprising dividing a tea extraction process into two systems which comprise one process (process A) for pressurizing and extracting green tea leaves to obtain the pressurized extract and the other process(process B) for extracting and filtering the extract to obtain atmospheric pressure extract, and then (process C) mixing the obtained pressurized extract with the obtained atmospheric pressure extracts in a mixing ratio determined on basis of the weight of the tea leaves of raw material.

Abstract: PROBLEM TO BE SOLVED: To produce a green tea drink which has an excellent flavor, contains aromatic ingredients in a good balance, and does not produce unpleasant precipitates. SOLUTION: This method for producing the green tea drink, comprising dividing a tea extraction process into two systems which comprise one process (process A) for pressurizing and extracting green tea leaves to obtain the pressurized extract and the other process (process B) for extracting green tea leaves at the atmospheric pressure and then finely filtering the extract to obtain the atmospheric pressure extract, and then (process C) mixing the obtained pressurized extract with the obtained atmospheric pressure extract in a mixing ratio determined on basis of the weight of the tea leaves of raw material. The pressurized extract in the process A contains the optimal smell ingredients in large amounts but insufficiently contains an astringent taste and a flavor, while the atmospheric pressure extract in the process B has a strong astringent taste, a strong flavor, and a good color. The green tea drink obtained by mixing the pressurized extract with the atmospheric pressure extract in a ratio within a prescribed range has an excellent flavor, contains aromatic ingredients in a good balance, does visually not generate dregs, and is especially suitable as a green tea drink packed in PET bottles.
