- epigallocatechin gallate which is a bitter taste component
- epicatechin gallate Provides a method for producing fermented tea beverages, fermented tea concentrated solutions or fermented tea concentrated powders that are free of epigallocatechin and epicatechin, have little bitter taste, no cream-down, and excellent aroma sweetness The purpose is to do.
- the inventor adds a large amount of water to the fresh tea leaves before wilt treatment and crushes with a mixer, and then removes the solids and heats them, or adds a large amount of water to the fresh tea leaves and crushes, and shakes for a short time. After that, by removing the solid content and performing the heat treatment, the tea-flavored fermentation is substantially free of epigallocatechin gallate and epicatechin gallate, has little bitter taste, and has no sweetness and fragrance cream down.
- tea drinks can be manufactured. That is, the present invention is a method for producing a fermented tea beverage, in which water is added to fresh tea leaves and crushed for 1 second to 40 minutes, preferably 5 minutes to 20 minutes.
- epigallocatechin gallate and epicatechin gallate are substantially free from the total amount of epigallocatechin gallate and epicatechin gallate in the product is 0 with respect to the weight of the raw raw tea leaves. It means less than 1%.
- HPLC high performance liquid chromatography
- the culture is preferably performed by adding 5 times (weight) or more, more preferably 7 times (weight) or more of fresh tea leaves.
- theaflavin 3-O-gallate and theaflavin 3′-O-gallate containing theaflavin as the main component are efficiently added to all catechins without adding an enzyme such as tannase or tea leaf tissue disrupting enzyme from the outside. And converted to theaflavin 3,3′-di-O-gallate to obtain a fermented tea beverage.
- the four types of catechins (EC, EGC, ECG, EGCG) contained in tea leaves and causing bitter and astringent taste are all catechin polymers, theaflavin and theaflavin 3-O-gallate.
- fermented tea beverages produced according to the present invention are bright orange and sweet, have a strong aroma, and contain bitter and astringent ingredients epigallocatechin gallate, epicatechin gallate, epigallocatechin and epicatechin. There is almost no bitter astringency so it has a mild taste.

- the fresh tea leaves used in the method of the present invention refer to tea leaves after harvest and before wilt treatment, or frozen tea leaves after harvest and before wilt treatment.
- Fresh tea leaves are raw tea leaves and stems, which may be used separately or in combination.
- any tea leaves of green tea varieties and black tea varieties that are generally cultivated can be used.
- Typical tea leaves cultivated in Japan include Asatsuyu, Yabukita, Yamato Midori, Makino Hara, Kanaya Midori, Okumidori, Ookaise, Okuhikari, Meiko, Samidori, Komakage, There are Yamanami, Mine Kaori, Hatsumomiji, Beni Fuuki, Beni Homare, Benihikari, etc.
- the fresh tea leaves may be used immediately after collection or may be used after being frozen and stored immediately after collection.
- the tea leaves may be collected at any of the 1st, 2nd, 3rd and 4th teas.
- the amounts of catechin, polyphenol oxidase, peroxidase, tannase, and hydrolase are different for each leaf, it is preferable to appropriately adjust the reaction conditions depending on the tea leaf of the material used.
- the second tea is desirable as the tea leaf used in the method of the present invention. In the case of No.
- an antioxidant for example, fruit juice such as ascorbic acid, sodium ascorbate, or lemon
- fruit juice such as ascorbic acid, sodium ascorbate, or lemon
- water is added to fresh tea leaves before the wilting treatment, and the fresh tea leaves are crushed using a mixer or the like.
- the crushing can be performed at a temperature of 0 ° C to 30 ° C. After crushing, the mixture is shaken and cultured without separating tea leaves and water.
- Peroxidase is an enzyme that produces theaflavin in the presence of hydrogen peroxide. In this case, since hydrogen peroxide is produced by metabolism, it may not be added from the outside.
- polyphenol oxidase is an enzyme that generates theaflavin in the presence of oxygen. Tannase can cleave gallate groups of catechins and theaflavins. The gallate group is also cleaved by the action of hydrolase. With this reaction, gallic acid is produced.
- EGCGs are dehydrogenated and condensed with each other's pyrogallol rings to produce theasinensin A
