text: It is important to note that catechin is a relatively low abundant polyphenol within green tea infusion and that its concentration stays between 0 μg/mL and 28.1 μg/mL. Temperature and brewing time have a synergistic effect on catechin concentration since concentration increased linearly from 50° C. to 80° C., while increasing significantly at 90° C. ( FIG. 2 and Table 2).
