This study investigated the effects of different levels of buckwheat bran inclusion onto the physicochemical, pasting properties and in vitro starch digestibility of buckwheat flour gels. Total phenolic content and antioxidant activities (DPPH radical-scavenging activity and ferric reducing/antioxidant power) were also measured. Total starch content per 100 g of gel ranged from 64.45 to 75.66, and the percentage of resistant starch ranged from 1.36% to 1.75%, while protein ranged from 12.07% to 12.93%. The results showed that the amount of bran addition decreased total starch and slightly reduced protein content, but increased resistant starch content. The level of bran addition increased the total phenolic content and antioxidant activity of the gels, while it reduced the blood sugar response. As the bran levels increased, the glucose released decreased (95.17, 84.08, 69.80, 60.23 mg glucose/g sample, respectively). The results showed that the bran of buckwheat (a pseudocereal) has nutritional value and can be used in the development of buckwheat products.
