Characterizing Texture, Color and Sensory Attributes of Cookies Made with Jerusalem Artichoke (Helianthus tuberosus L.) Flour Using a Mixture Design and Browning Reaction Kinetics

초록

Effect of interactions between Jerusalem artichoke flour (JF), wheat flour (WF) and sugar (S) on the texture properties of cookies was investigated. JF was the most influential component on the dough and cookies, possibly due to inulin in JF. To develop an optimum formulation using mixture design, the constraint values for the quality indices were: hardness (12 N), adhesiveness (10 mJ), and cohesiveness (0.27) of dough, and maximum force of cookie (73 N). Optimum values of WF, JF and S in the mixture were found to be 151.89 g, 55.33 g and 87.78 g, respectively, with a desirability of 0.943. Two experimental cookie formulas, similar to the optimal formula, were tested for their sensory properties and resulted in highly acceptable scores. As baking time increased, the browning and antioxidant activity of all cookies increased; however, the browning and antioxidant activity of samples containing JF was significantly higher than the others.
