In this study, the effect of baking conditions and dough formulations on phenolic compounds, antioxidant
capacity and color of cookies made from anthocyanin-rich corn flour were investigated. The control
cookies were prepared from dark-red popping corn, blue popping corn and blue-standard corn flour
according AACC method 10e54 and baked at 200 C for 7 and 10 min. In control corn cookies, the content
of total flavonoids and anthocyanins, as free water-soluble phenolic compounds, was reduced by applied
baking conditions. Our results show that citric acid significantly increased the total flavonoids and anthocyanins
content in the cookies prepared from blue popping corn and blue-standard corn. Compared
with the control cookies baked at 200 C for 7 min, the cookies prepared with 0.5 g/100 g added citric
acid and baked at 150 C for 12 min had higher contents of total flavonoids and anthocyanins by 60 and
70%, respectively. However, as a result of Maillard reaction inhibition at low pH, antioxidant capacity of
anthocyanins-rich blue popping corn and blue standard corn cookies with 0.5 and 1 g/100 g citric acid
was lower by 56 and 39%, respectively, compared to antioxidant capacity of their control cookies baked at
200 C for 10 min.
