dc.description.abstract | Aqueous extracts from seven coloured potato varieties (three red-fleshed, three-purple fleshed, and one
marble-fleshed genotype) were studied for their anthocyanin content, in vitro biological activities,
colouring properties and their potential application in the food industry. Acylated glycosides or
pelargonidin and petunidin aglycones were identified as the main anthocyanin forms in the red and purple
varieties, respectively. The total anthocyanin content among varieties ranged from 478.3 to 886.2 mg/100
g extract. All the extracts presented in vitro antioxidant, antibacterial and antifungal activities, whereas no
toxic effects were detected. Finally, two selected extracts were tested as colourants in a soft drink
formulation and presented suitable sensory profiles as well as high colour stability during a 30-day
shelf-life when compared with the commercial colourant E163. Therefore, the tested extracts could be
used as natural food colourants. | sr |
