Abstract:Grape and carrot were used to make composite juice beverage. The optimal formula of the beverage were determined through single-factor and orthogonal tests. The results showed that the optimal formula was sugar 10%, grape-carrot mixed juice 20% and citric acid 0.1%. The optimal composition of the composite stabiizer was xanthan gum 0.4 g/L, CMC-Na 0.6 g/L and sodium alginate 0.8 g/L.
