This study showed that small amounts of RWG led to an increase in the gluten and disulfide bond content of dough compared to the control. The DWG had similar effect on disulfide bond content, but decreased the gluten content of dough. Steamed bread containing 1–3% germ had similar elasticity, cohesiveness and resilience, but relatively higher hardness and chewiness. However, poor qualities of steamed bread such as the dark yellow color, small volume, high hardness and low elasticity developed when the germ content was higher than 11%. This result was consistent with sensory evaluation.
