摘要： Green tea extracts having improved clarity and color. These extracts are obtained by treating the green tea extract with an amount of a food grade cation exchange resin effective to remove metal cations present in the extract. The treated extract is then contacted nanofiltration membrane while the treated extract is at a temperature of from about 100.degree. to about 140.degree. F. (from about 37.8.degree. to about 60.degree. C.) to provide a filtered green tea extract as the permeate. These green tea extracts can be included in a variety of beverages and are especially useful in suppressing the characteristic aftertaste of aspartame in diet beverages.

摘要翻译： 绿茶提取物具有改善的清晰度和颜色。 这些提取物通过用一定量的有效除去提取物中存在的金属阳离子的食品级阳离子交换树脂处理绿茶提取物而获得。 然后处理的提取物接触纳滤膜，而处理的提取物处于约100°至约140°F（约37.8°至约60℃）的温度下，以提供过滤的绿茶提取物作为渗透物。 这些绿茶提取物可以包含在各种饮料中，并且特别可用于抑制饮食饮料中阿斯巴甜的特征回味。
