Effect of culture time on the clarification and the antioxidant capacity of kombucha beverage was studied. The expermental results showed: (1)when the culture time was prolonged, the clarity of kombucha beverage gradually decreased; the kobucha beverage cultured for 5 days has a higher clarification more than 80%;but the clarity of kombucha beverage significantly decreased after culturing for 5 days. (2)kombucha beverage showed strong scavenging capacity on 1,1-diphenyl-2-pierylhydrazyl (DPPH) and ·OH radical. Expermental results aloso indicated that the scavenging capacity of kombucha beverage on DPPH and ·OH radical increased within the five days, and gradually decreased with the prolonging culturing time after 5 days.
