Abstract:According to the characteristics of the body of the athlete changes， developed a new sports drink， in which the banana and soy peptides were the main raw materials.The optimal formula and processing parameters were determined through single factor experiments，orthogonal experiment and sensory evaluation. The best ster－ ilization process conditions were 110 ℃ for 15 s.The results showed that the best formula of banana juice soy peptides sports drinks composite beverage was that banana juice 100 g， inorganic salts 2.0 g，soy peptides 1.6 g， sucrose 12 g， citric acid 0.20 g and glucose 0.5 g. The obtained beverage has characteristics of smooth taste nu－ trient rich， delicate taste， is a high value of sports drinks.
