Waffles with cinnamon powder added in different proportions (0-12% of wheat flour) were baked to investigate the effects of baking on the physicochemical properties and antioxidant activity. Compared with the control without cinnamon, baking loss was lower in waffles with cinnamon, which led to a decrease in waffle hardness. This was attributable to the higher water-holding capacity of cinnamon than wheat flour. With the increase in the amount of cinnamon, the springiness, resilience, and cohesiveness of the waffle decreased, which was thought to result from the decrease in gluten formation by the proportional decrease of wheat flour. The total reducing capacity and DPPH radical scavenging activity of the waffle was significantly increased. This was substantially in agreement with the observations that cinnamon had an appreciable total reducing capacity and radical scavenging activity that were unchanged by heat treatment. This indicates that the antioxidant functionality of cinnamon could be effectively added to thermally processed food.
