The results showed that adding excessive amount of detoxified, partially defatted flaxseed meals could decrease the specific volume and expansion ratio of steamed bread, and the bread turns dark in color. The textural test showed that the hardness, gumminess, and chewiness of steamed breads increased continuously with increasing
