Abstract: This study aimed to develop a new green tea and dragon fruits compound beverage with unique flavor, with green tea and dragon fruits as the main raw materials, supplemented by some citric acid and sucrose. Single factor experiment was adopted to determine the screening level range of orthogonal experiment, and then combined the orthogonal experiment analysis results and comprehensive sensory score to optimize the processing technology and formulation of the beverage. The result showed that the best technological parameters of optimum green tea-dragon fruits compound beverage were as follows: green tea to dragon fruits ratio of 2:1, the skimmed milk concentration of 9%, citric acid addition of 0.20%, sugar addition of 4%. Under these conditions, the product obtained good taste and excellent stability with the content of protein of 9.34 mg/mL, the Vc content of 438 μg/mL, the total sugar content of 2.5%, the tea polyphenol content of 11.5%, there were no toxic elements and microbial contamination, and this processing technology would provide academic and theoretic ground for fruit composite beverage production.
