ITO EN Ltd. and Ito En Sangyo Ltd. | Date: 2014-05-14

The present invention provides a new invention provides a new infusion bag that is easy to hand1e even if a long hanging string is used, allows easy infusion, and prevents the hanging string from being caught in a sea1 part during individual-package sealing. Said infusion bag I is provided with the following: a bag part 2 that contains the substance to be used to produce an infusion; and a hanging string 3, the tip of which is affixed to a tag 5 for holding the infusion bag and the base end 3a of which is affixed to the surface 4 of the bag part 2. This infusion bag is characterized by a structure wherein: the hanging string 3 is coiled into a spira1 and disposed on the surface 4 of the bag part 2; and the tag 5 is detachably affixed to the surface 4 of the bag part 2 so as to cover the hanging string 3.

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.


A green tea beverage is packed in a container, which makes it possible to sense a deep aroma passing through the nasal cavity when the beverage is drunk cold, in particular even when time has passed since the container was opened and the beverage temperature has increased and become lukewarm, by adjusting the ratio (SSS/SS) of the concentration of settleable suspended solids (SSS) to the concentration of suspended solids (SS) in the green tea beverage to 0.07 to 0.48 and adjusting the ratio (sucrose/sugars) of the concentration of sucrose to the concentration of sugars, which is the sum of the concentration of monosaccharide and the concentration of disaccharide, to 0.74 to 0.94.


There has been a need to provide a green tea beverage packed in a container which exhibits a smooth feeling in the throat and a lingering taste when the beverage is drunk cold, in particular even when time has passed since the container was opened and the beverage temperature has increased and become lukewarm. The present invention provides a green tea beverage packed in a container which exhibits a smooth feeling in the throat and a lingering taste when the beverage is drunk cold, in particular even when time has passed since the container was opened and the beverage temperature has increased and become lukewarm, by adjusting a particle diameter of cumulative 90 mass % (D90) in a tea extracted liquid to 3 m to 60 m and adjusting a sugar/tartness degree ratio to 0.12 to 0.43.

Provided is a caffeine-reduced green tea beverage packed in a container which can be enjoyed either hot or cold, and which has a sweet aroma and rich full-bodied flavor. 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 150 ppm to 500 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 2.0 to 13.0; a ratio of ester catechins to sugar concentration (ester catechins/sugars) that falls within the range of 0.9 to 2.2; and a percentage of the concentration of theanine to the concentration of caffeine (theanine/caffeine100) of at least 10.0.

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)]0.35(2)

Ito En Ltd. | Date: 2010-02-25

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.


A method of manufacturing a liquid food/beverage packed in a container obtained by diluting a raw material liquid with a diluting liquid having a lower viscosity than that of the raw material liquid includes: a diluting liquid heating step of heating the diluting liquid up to a higher temperature than that of the raw material liquid before being mixed with the raw material liquid; a primary heating/diluting step of swirling the diluting liquid in the raw material liquid to generate a swirl flow thereby to dilute the raw material liquid while heating the raw material liquid through heat convection of the swirl flow; and a secondary heating/sterilizing step of, after the primary heating/diluting step, heating and sterilizing a mixed liquid of the raw material liquid and the diluting liquid by conductive heat.
