Refine’s purple sweet potato pigment is a pigment obtained by extracting tuberous roots of Ipomoea batatas (Convolvulaceae). This purely natural and water-soluble edible haematochrome is produced after processes of sorting, cleaning, cutting, soaking, filtering, refining, concentration, sterilization (finished product of purple sweet potato pigment- liquid) and spraying drying (finished product- powder).
The principle pigment components of purple sweet potato pigment are cyanidin acyl glucoseide and peonidin acyl glucoside.
