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.
