Green tea extract subjected to cation exchange treatment and nanofiltration to improve clarity and color |
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 DEG to about 140 DEG F. (from about 37.8 DEG to about 60 DEG 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.
