  • Patent number: 9668495
    Abstract: Disclosed is a green tea beverage packed in a container which has a strong fire odor (savory odor), yet gives a refreshing aftertaste and can be drunk delectably even in a cold state. Specifically disclosed is a green tea beverage packed in a container characterized in that the saccharide concentration thereof, which is the sum of the monosaccharide concentration and the disaccharide concentration, is 100 to 300 ppm and the ratio of the disaccharide concentration to the monosaccharide concentration (disaccharides/monosaccharides) is 10 to 28. It is preferred that the ratio of catechins with electron localization to said saccharide concentration (catechins with electron localization/saccharides) is 1.0 to 2.5.

  • Publication number: 20160330991
    Abstract: The present invention provides new tea leaves from which it is possible to extract tea which well suits Japanese-style foods, is rich in tastiness, and has a light flowery aroma. These tea leaves are characterized by containing (A) a lipid, (B) a tannin, (C) a hydrophilic low-molecular-weight tea polyphenol, and (D) a semi-hydrophilic low-molecular-weight tea polyphenol in a mass proportion that satisfies the following relationships (1) and (2). 0.20?(A)/(B)?0.50??(1) 0.15?(D)/[(C)+(D)]?0.

  • Patent number: 8728557
    Abstract: Disclosed is a new fruit-juice-containing black tea beverage that, without performing enzyme treatment such as tannase treatment, and moreover even if a large quantity of fruit juice is added, can suppress time degradation. The fruit-juice-containing black tea beverage packed in a container containing 10-90 mass % of fruit juice is characterized by containing 10-24 ppm of theogallin, and by the ratio (theogallin/K) of contained theogallin to contained potassium being 0.015-0.100.

  • Publication number: 20130017307
    Abstract: Disclosed is a pleasantly mild new acidic black tea beverage in which bitter and astringent flavors are suppressed. The black tea beverage packed in a container contains sweeteners and fruit juice and 0.001 to 0.005 wt % caffeine, and is characterized by having acidity of 0.02 to 0.08%, and, when the acidity is within the aforementioned range, and a sweetness/dryness of 1.50 to 2.50, said sweetness/dryness being expressed using sweetness (total solids content) and acidity.

  • Publication number: 20120308712
    Abstract: Provided is a caffeine-reduced green tea beverage packed in a container which can be enjoyed either hot or cold, and which has a sense of being concentrated due to its roasted aroma, and which has an astringent richness, while at the same time being refreshing. The green tea beverage packed in a container has a caffeine concentration of less than 90 ppm, and a total sugar concentration (obtained by adding the concentration of nonreducing sugars and the concentration of reducing sugars) that falls within the range of 100 ppm to 300 ppm; a ratio of the concentration of nonreducing sugars to the concentration of reducing sugars (non-reducing sugars/reducing sugars) that falls within the range of 13.0 to 23.0, and a ratio of ester catechins to sugar concentration (ester catechins/sugars) that falls within the range of 0.4 to 1.1.

  • Publication number: 20120301594
    Abstract: Provided is a roasted green tea beverage packed in a container, which has a noticeable roasted aroma and a rich, astringent and yet light flavor and tastes good even in a cold state. The roasted green tea beverage packed in a container is characterized by: the caffeine concentration being less than 90 ppm; the concentration of saccharides, i.e., the sum of reducing saccharides and non-reducing saccharides, being 60-220 ppm; the ratio of the non-reducing saccharide concentration to the reducing saccharide concentration (non-reducing saccharides/reducing saccharides) being 5.0-15.0; the gallic acid concentration being 20-80 ppm; and the pH being 5.5-6.3.

  • Publication number: 20110311705
    Abstract: Disclosed is a roasted green tea (Hojicha) beverage packed in a container which has a strong roasted aroma, a light taste and a refreshing aftertaste and can be drunk delectably even in a cold state. Specifically disclosed is a roasted green tea beverage packed in a container, characterized by: the concentration of saccharides, i.e., the sum of monosaccharides and disaccharides, being 60-220 ppm; the concentration ratio of disaccharides to monosaccharides (disaccharides/monosaccarides) being 5.0-15.0; and the concentration ratio of the aforesaid saccharides to gallic acid (saccharides/gallic acid) being 2.0-5.0. It is preferred that the concentration ratio of catechin showing electron localization to soluble solid matters originating in tea leaves [catechin showing electron localization/(soluble solid matters originating in tea leaves×100)] is 5.0-9.0. Also, it is preferred that the ratio (catechin showing electron localization/saccharides) is 0.8-1.8.
