Abstract:A functional beverage pomegranate carrot juice were prepared from the fresh pomegranate juice mixed with carrot juice at mass ratios 1 ∶3，3 ∶1 and1 ∶1.The changes of physico-chemical properties（pH value，total soluble solids，total acidity），ascorbic acid，total phenol and antioxidant activity were studied during the storage period of 60 days at room temperature （25±1）℃.The results showed that the pH values of the three samples were 4.04，3.92 and 3.38 respectively，the soluble solids were 5.02 %，6.14 % and 8.13 %respectively，and the total acidity was 0.74，0.74 g/100 mL and 0.77 g/100 mL respectively.The pH value decreased，the soluble solids content did not change significantly，while the total acidity increased during the shelf life of 60 days at the three blending ratios.The content of ascorbic acid in the blends juice with the mass ratio of 1 ∶3 was superior，the content of total phenol and the scavenging rate of DPPH radical with the mass ratio of 3 ∶1 were superior，and the three indexes showed a general downward trend in the shelf life.The sensory evaluation score of pomegranate carrot juice with a mass ratio of 1 ∶1 was the highest.
