"Big Ten" mulberry was the raw materials,the scientific blending and carefully processing produced a nutrient enriched instant tea.Through a series of single factor and orthogonal test,the best formula of mulberry instant tea and optimum conditions were obtained.The results showed 20% maltodextrin was the best drying agent.By spray-drying method,the optimum parameters were: nebulizer nozzle speed 30 000 r/min,the material feeded speed 40 r/min,inlet and outlet temperature 180/80℃.The mulberry instant tea formula was: original fruit juice content70%,sugar acid ratio 20∶ 1,sugar content 8.0%.
