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 with a nanofiltration membrane while the treated extract is at a temperature of from about 100~ to about 140 ~F (from about 37.8~ to about 60 ~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. |
