The effects of the addition of 0-3.0 wt% -cyclodextrin (-CD) and -cyclodextrin (-CD) on the quality of wheat flour as well as the texture and the aging of prebaked bread were evaluated. The addition of -CD and -CD increased the ability of wheat flour to absorb water and shortened the times of dough formation and stabilization. Amylase activity slightly increased after using 2.0 and 3.0 wt% of -CD and -CD, respectively. Moreover, the addition of -CD and -CD increased the fermentation height and gas retention ability of dough. Dough samples containing 2.0 wt% -CD and 3.0 wt% -CD showed the highest fermentation heights and gas retention volumes, respectively. Dough gas production increased with the addition of -CD. Gas production by dough samples containing more than 2.0 wt% -CD exceeded that by samples in the control group. The results of the texture crumb of bread and specific volume tests revealed that the addition of 2.0 wt% -CD and 3.0 wt% -CD reduced bread hardness and increased bread elasticity, resilience, and specific volume. The optimal -CD and -CD contents were identified as 2.0 wt% and 3.0 wt%, respectively. The addition of 2.0 wt% -CD and 3.0 wt% -CD delayed the aging of prebaked bread and reduced the hardness of prebaked bread during different weeks of storage, which may be due to decreasing the melting enthalpy of starch crystals. This work elucidated the mechanisms underlying the effects of CD addition on prebaked bread quality.
