From the data in Table 4, it appears that the antioxidant activities
of snacks obtained with flour from the Blue Congo and Valfi
potatoes and products that were not supplemented with coloured
flour were significantly lower compared to the antioxidant activity
of the dough. In contrast, a 50% increase in antioxidant capacity was
observed in snacks after the addition of flour from Salad Blue and
Herbie 26 potatoes. These differences could be due to a higher degradation
of total polyphenols in snacks supplemented with Blue
Congo and Valfi potato flour
