Physico-chemical characterization of Purple flesh potato and its extract (PPE).

Sample	PP	PPE
Moisture content (%)	75.6 ± 3.7 ^a	35.0 ± 0.4 ^b
Soluble solids (°Brix at 20 °C)	5.2 ± 0.1 ^b	65.0 ± 0.5 ^a
Total Anthocyanins (mg cy-3-glu/g)	0.24 ± 0.02 ^b	2.0 ± 0.1 ^a
Antioxidant capacity (FRAP) (mg TE/g)	4.7 ± 0.3 ^b	21.1 ± 0.5 ^a

PPE: purple potato extract; cy-3-glu: cyanidin-3-glucoside; TE: Trolox equivalent. Different letters indicate statistically significant differences between systems for the Tukey multiple range test (p < 0.05). a correspond to highest values and b correspond to lowest values.
