    • Provided is a process for producing a purified green tea extract of high quality by readily and efficiently purifying a green tea extract in a simple manner. A process for producing a purified product of green tea extract, which includes subjecting an aqueous solution of green tea extract to solid-liquid separation by filtration and/or centrifugal separation to obtain another aqueous solution of green tea extract, said another aqueous solution having a turbidity of from 0.2 to 2.0 as measured with a concentration of non-polymer catechins in it adjusted to 1 wt %, and then allowing the another aqueous solution of green tea extract to pass through a polymer membrane having a membrane pore size of from 0.05 to 0.8 μm such that the turbidity of the another aqueous solution of green tea extract is reduced to lower than 0.2 as measured with a concentration of non-polymer catechins in it adjusted to 1 wt %.
    • 本发明提供一种通过以简单的方式容易且有效地净化绿茶提取物来生产高质量的纯化绿茶提取物的方法。 一种生产绿茶提取物的纯化产物的方法,其包括通过过滤和/或离心分离使绿茶提取物的水溶液进行固液分离,得到另一种绿茶提取物水溶液,所述另一种水溶液具有 将浓度为1重量%的非聚合物儿茶素类的浓度测定为0.2〜2.0的浊度,然后使另一种绿茶提取物水溶液通过膜孔径为0.05〜0.05的聚合物膜 0.8μm,使得绿茶提取物的另一个水溶液的浊度降低到低于0.2,其中非聚合型儿茶素类的浓度被调节至1重量%。
