| Abstract: | The beverage technology of purple sweet potato were investigated. And the color protection and liquefaction technology of the purple sweet potato starch were determined. The optimum color protection condition was achieved by treating purple sweet potato slices with (Vitamin C ∶Citric acid=3∶2)of 0.5%at 20 ℃ for 10 min;the liquefied best conditions: hydrolyzing with 0.4% amylase at 70 ℃ for 60 min. After optimizing, the purple potato beverages is good taste and nutrition-rich. |
