Five Chinese wheat cultivars (Anhwei Bai Mai, Gao You 503, Ji Mai 20, Ji Nan 17, and Xi Nong 979, abbreviated as AHBM, GY503, JM20, JN17, and XN979, respectively) were milled after debranning at different degrees. The flour characteristics and qualities of steamed bread made from these flours were evaluated to study the effect of debranning degree. The results showed that the yields of flour of all samples were increased with the augment of debranning degree. The starch damage contents were decreased to a suitable scope for Chinese steamed bread (CSB) making, while the ash contents increased in most of the cases. The effects of debranning on the characteristics of flour were correlated with hardness of wheat cultivars and debranning degree. For AHBM and JM20, the qualities of steamed bread made from unpearled wheat were better than pearled ones. At the same time, for GY503, JN17, and XN979, 5.0% debranning degree improved the characteristics of flour and qualities of CSB.
