Mantou (steamed bread) is a Chinese fermented wheat product that is cooked in steamer. Whole wheat flour (WWF) is healthier than regular wheat flour (WF). This study investigated the physicochemical properties of dough and mantou made from WF and/or WWF. Results showed that the substitution of WF by WWF resulted in stiffer and less extensible dough. Both Peleg-Normand and Wiechert models fitted well to the stress relaxation data of mantou. Increasing the substitution level of WWF led to the decrease of k1 and k2 in Peleg-Normand model as well as λ1 and λ2 in Wiechert model. Mantou with 100% WWF had significantly higher hardness but lower cohesiveness and specific volume than regular mantou. However, free and bound phenolics and DPPH radical scavenging capacity of mantou obviously increased with the amount of WWF. Mantou with 25% WWF had the highest overall sensory score among all mantous tested. [ABSTRACT FROM AUTHOR] |
