DIFFERENT PREPARATIONS OF TEA EXTRACTS AND HERBAL DECOCTIONS Influence on their antioxidant capacity and reactivity

Tea is a powerful antioxidant beverage consumed in many soft drinks today. The characterization of its antioxidative properties during and especially after its preparation procedure, inclusive their long time stabilities, is an important tool for the soft drink industry. The antioxidative capacity and re- activity are two parameters which gives a compre- hensive description of the antioxidant properties. Both parameters are integrated in the antioxidative power AP, a 2D factor. The AP of the green tea bev- erage exceeds all other types of tea. Black tea has an AP which is six times lower than that of green tea.
