    • A packaged green tea beverage, wherein (A) the packaged green tea beverage contains from 0.08 to 0.5 wt % of non-polymer catechins, (B) a percentage of non-epicatechin body in the non-polymer catechins is from 5 to 25 wt %, (C) a percentage of gallate body in the non-polymer catechins is from 5 to 95 wt %, (D) pH is from 2.5 to 5.1, and (F) the packaged green tea beverage contains from 0.0001 to 20 wt % of at least one sweetener selected from fructose, glucose, sucrose, fructoglucose syrup and glucofructose syrup. A packaged green tea beverage containing non-polymer catechins in high concentration can be provided, which can not only reduce astringency but also provides for adequate sweetness and sourness without impairment of the taste and is suited for long-term storage while containing a sweetener.
    • 一种包装的绿茶饮料,其中(A)包装的绿茶饮料含有0.08至0.5重量%的非聚合物儿茶素类,(B)非聚合型儿茶素类中的非表儿茶素体的百分比为5至25重量% %,(C)非聚合型儿茶素类中没食子酸酯体的百分比为5〜95重量%,(D)pH为2.5〜5.1,(F)包装的绿茶饮料含有0.0001〜20重量% 的至少一种选自果糖,葡萄糖,蔗糖,果糖葡糖糖浆和葡萄糖果糖糖浆的甜味剂。 可以提供含有浓度高的非聚合型儿茶素类的绿茶饮料,其不仅可以减少涩味,而且可以提供充分的甜味和酸味,而不会损害味道,并且适用于含有甜味剂的长期保存。

    • A process for producing a tea extract containing non-polymer catechins, which includes immersing unfermented tea leaves in ethanol or an ethanol-water solution having an ethanol concentration of from 85 to 99.5 vol % to obtain unfermented tea leaves having a percentage catechin residue of at least 80 wt % based on a catechin content of the unfermented tea leaves before the immersion in the ethanol or ethanol-water solution, and then extracting the unfermented tea leaves with warm water or hot water. The highly-efficient extraction of non-polymer catechins makes it possible to obtain a tea extract, which has an improved taste and does not produce sediment when added to beverages.
    • 一种生产含有非聚合型儿茶素的茶提取物的方法,包括将未发酵的茶叶浸入乙醇或乙醇浓度为85-99.5体积%的乙醇 - 水溶液中,得到未发酵的茶叶,其百分数为儿茶素​​残留量 基于在浸没在乙醇或乙醇 - 水溶液中之前的未发酵茶叶的儿茶素含量,至少80重量%,然后用温水或热水提取未发酵的茶叶。 非聚合物儿茶素类的高效提取使得可以获得具有改善的味道并且当添加到饮料中时不产生沉淀物的茶提取物。
