Figure 5

Effects of β-CD on dissolved oxygen in tea infusion. Solid line with “◆” represents conventional infusion; solid line with “■” represents infusion made with 0.05% β-CD when extraction. Dissolved oxygen levels were measured from aliquots of the same sample or from different samples over the course of 3 hours.
