Definitions
- the present invention relates to a method for producing a green tea flavor having an improved taste, and a beverage to which the green tea flavor is added to enhance the green tea feeling and impart "nourishment".
- the present invention relates to a method for producing a dry green tea polyphenol, which is a polyphenol derived from green tea leaves and has reduced unpleasant odor and unpleasant taste derived from green tea after being heat-sterilized after being added to the beverage, and a beverage using the same.
- tea-based beverages in a form filled in cans, PET containers, and the like have been marketed. While these beverages have the purpose of static beverages, in terms of taste, they actually have one aspect of tasted beverages compared to beverages prepared from tea leaves by their own hands.
- Containerized beverages such as cans and PET containers are sterilized and can be stored for a long period of time, so they are easy to consume at any time. However, it is difficult to say that consumers are always satisfied with the taste.
- beverages that emphasize umami are extracted with a relatively dilute component composition in order to suppress the generation of heat-sterilized odors.
- shige is one of the general expressions of the taste of green tea, and the components that make up the taste are amino acids, catechins, purine bases, sugars, organic acids, minerals, etc. It is said that it is related to the harmony of foods, and it is said that the central role is played by amino acids and power techins (Cooking Science, Vol. 25, No. 1, p. 55, 1992).
- Japanese Patent Application Laid-Open No. 2000-50799 discloses a method for extracting tea having an umami taste and a less astringent taste by immersing tea leaves in still water in which dissolved oxygen is removed and kept at 0 to 36 ° C.

- Japanese Patent No. 3018013 Japanese Patent No. 3018013
- Two methods can be considered for blending the active ingredients, such as kytechins, in high concentrations.
- One is a method in which ground tea leaves are added (Japanese Patent Laid-Open No. Hei 10-234301).
- this method when the pulverized material is mixed at a high concentration, the powder becomes crushed, and the pungent and aftertaste is not good.
- the ground tea leaves which are the active ingredients, sink to the bottom or float on the upper surface.
- the presence of such sedimentation greatly impairs the commercial value in appearance.
- a precipitate may be formed in a beverage that has a physiological effect, but when drinking, it is necessary to perform an operation of uniformly dispersing the ground tea leaves, such as shaking or stirring the whole.
- Another method is to add a concentrated tea extract or a concentrate of a commercially available tea extract and a purified product thereof (hereinafter referred to as a catechin preparation) to increase the amount of tetekins in a dissolved state.
- a concentrated tea extract or unpurified potency techin preparation is used, the uncomfortable feeling of drinking with tea powder etc. is improved, but an unpleasant odor is generated during the heat sterilization of the beverage, and dissolved catechin Since beverages have bitter and astringent tastes, beverages containing a large amount of a force techin preparation will have an unpleasant odor, bitterness, and astringency.
- catechins need to be drinkable for long-term or daily use in order to obtain the physiological effects, beverages obtained by these means did not meet this requirement .
- Japanese Patent Application Laid-Open No. 2001-231450 discloses a method for producing a green tea can beverage using a green tea extract liquid after the second roast, from which components causing off-flavor have been removed. Since this method focuses on the extraction of catechins from the extract and the suppression of heat sterilization odor, there is a restriction on the formulation that the components of the first roast cannot be used. Also, the problem of too strong bitterness and astringency in beverages containing high concentrations of catechins is discussed. It has not been solved.
- Japanese Patent Application Laid-Open No. 1-13491 discloses a method for producing tea beverages such as sencha-ryu-cha, which extracts tea with cold water at a temperature of 20 ° C or less to remove a cold-water extract.
- a technique for suppressing the heat sterilization odor by re-extracting the residue with hot water at 3.0 to 95 ° C is disclosed.
- the problem that the first ingredient cannot be used has not been solved, and the same problem as described above remains.
- there was a problem that the generation of "small taste" in the second roast could not be suppressed because the conditions of cold water extraction in the first roast were not accurate.
- an object of the present invention is to provide a method for producing a green tea leaf-derived polyphenol, which has reduced unpleasant odor and unpleasant taste derived from green tea after being heat-sterilized after being blended into a beverage, and which is a polyphenol derived from green tea leaves, and a beverage using the same. Is to provide a law.
- an object of the present invention is to provide a high-concentration phytotechin without losing the original flavor of beverages and without losing the original aroma associated with sterilization derived from green tea extract. It is to provide a beverage without any.

- Extract 1 100 g of green tea leaves were packed in an extraction column having an inner diameter of 7 cm and a height of 40 cm, and 150 OmL of cold water at 0 ° C was circulated at 50 OmL per minute for 10 minutes by a pump for extraction. After the extraction, 130 lmL of the extract was recovered and used as extract 1. The catechin concentration in Extract 1 was 108 mgZl OmL.
- Extract 2 was recovered and rapidly cooled with ice water to obtain Extract 2.
- the catechin concentration in Extract 2 was 474 mgZlO OmL.
- Extract 1 (194 g), Extract 2 (194 g),] 3-cyclodextrin (2.88 g), and ascorbic acid (0.8 g), ion-exchanged water (350 g) were added, and the mixture was adjusted to pH 6.2 with a 5% aqueous sodium bicarbonate solution.
- Exchange water was added to make the total amount 800 g. This was filled in a can and sterilized at 121 ° C for 20 minutes to obtain a beverage of Example 12.
- the strength of techin in the beverage was 124 mg / l OmL.
- Extract 1 was obtained according to Table 5. Extract 1 was blended in the same manner as in Example 12, filled in cans and sterilized to obtain a beverage of Comparative Example 15. '

- Comparative Examples 16, 17, and 18 were milder than Comparative Example 15, but the original taste disappeared as the extraction temperature of Extract 1 was increased, and the unpleasant taste became stronger. Although the generation of heat sterilization odor was small, the bitterness was increased as the extraction temperature of Extract 1 was increased, and the aftertaste was markedly increased. In Comparative Example 19, although the generation of heat sterilization odor was small and the bitterness was moderate, generation of unpleasant taste and astringency remaining in the aftertaste were observed.
