process include milk, ice cream, wet noodle, dry noodle, and flour look for quantity of total glucose, antioxidant activity, and
antosianin decreaseful colour. Method of research include analyse quantity of total glucose assay fenol method, antioxidant
activity assay Diphenyl Pycril Hydriazil(DPPH), and observation in antosianin decreaseful colour product. The result of research
show that the best food product is purple sweet potato flour. That product has quantity of total glucose 2,805 g/100 g, IC50-
49951 %, and antosianin colour product take no damage because it still look purple.
