Abstract: Stigmata maydis extract was prepared by biological enzyme technology, which contained effective components such as flavonoid and polysaccharides. Functional beverage was developed with stigmata maydis extract, balsam pear juice and whey protein solution. By mixture experiment design, optimum basic recipe of the functional beverage was stigmata maydis extract 38. 33%, whey protein solution 38. 33%, balsam pear juice 23. 33%. By the single factor experiment and sensory analysis, the concentration of β-dextrine, xylitol and citric acid was 0. 12%, 3% and 0. 01%, respectively. And as detection factor of precipitation percentage of the products, composite stabilizers were CMC 0. 15% and locust bean gum 0. 15%, respectively.
