In this study, some functional components of the beet juice were analyzed and the beet juice sports drink was developed. Through single-factor and orthogonal experiments, the optimum formula of the beverage was determined as follows : beet juice 2.8%, CMC-Na 0.1%, salt 0.1%, citric acid 0.07%, sugar 3.46% , glucose 0.87%, β-cyclodextrin 0.15% and ascorbic acid 0.07%. The product tasted moderate and had good stability. The physicochemical and microbiological indicators of the product accorded with the requirements of the sports drink.
