Abstract: To provide a new manufacturing method of containered green tea beverage suited for selling hot. A step of eliminating silica was introduced in the manufacturing process, wherein the silica is eliminated after adding silica to a tea extract obtained by extracting green tea leaves to adsorb the sediment component present in tea extract to the silica. By adding silica to the tea extract and bringing them into contact, the proteins and polysaccharides causing secondary sediment can be selectively adsorbed and decreased, allowing the occurrence of sediment to be prevented, even when selling the beverage hot. Furthermore, it allows a large amount of flavor component to be left. Further more, a large amount of catechins can be left in the beverage, allowing the growth of heat-resistant bacteria to be inhibited by the antibacterial action of catechins.

Abstract: The present invention provides a thermally crosslinking type curable composition having the following excellent performance and properties: it needs no poly vinyl chloride resin, and exhibits excellent adhesiveness even to aluminum alloy materials and the like. The curable composition is characterized in that a diluent and an adhesion promoter are compounded with a composition containing uncrosslinked type and/or partially crosslinked type synthetic rubber, a plasticizer, a filler and a core-shell type acrylic resin. As the diluent, there are preferably used paraffinic or naphthenic hydrocarbons obtained by distillation of crude oil, or chemically synthesized hydrocarbons which are the second or third class petroleum having a molecular weight of 200 or less.

Abstract: Providing a manufacturing process of tea beverages that the secondary sediment does not occur even during the long-term storage. In the manufacturing process, determining the strictinin content in a tea extract or formulation of before-heat-sterilization, to manage to manufacture the strictinin content to be at or below the predetermined level. Since the strictinin in the tea extract or formulation decomposed to ellagic acid which is a cause substance of the secondary sediment after heat-sterilization, the occurrence of secondary sediment can be prevented previously by managing the manufacturing process to control the strictinin content in the tea extract or formulation of before-heat-sterilization.

Abstract: In order to produce green tea beverages which have a good flavor and a good balance of the fragrant components and do not form unpleasant precipitates, such green tea beverage are produced by a method including an extracting step consisting of two extraction steps, a first step in which green tea leaves are extracted at an applied pressure to obtain a pressure extract (step 1) and a second step in which green tea leaves are extracted under atmospheric pressure, followed by microfiltration to obtain an atmospheric extract (step 2), and a mixing step in which the pressure extract and the atmospheric extract obtained in the respective step are mixed at a mixing ratio determined on the basis of the weight of the raw tea leaves (step 3).

Abstract: Tea leaves are extracted in warm or hot water, and the obtained extract is contacted with a cation exchange resin ionically bonded to potassium ion. The potassium ion is ionically bonded to the cation exchange resin in advance. Divalent ions in the tea beverage are replaced with the potassium ions from the cation exchange resin. The electrical conductivity of the extract is controlled in this whole process. The natural flavor and quality of the tea are thereby maintained more certainly, since metal ions that cause muddiness or precipitation are effectively removed.
