摘要：Wholegrain buckwheat flour was used to substitute 15 %, 30 % and 40 % of wheat flour to make buckwheat enriched wheat bread. Proximate composition, sensory evaluation, total phenols content and antioxidant activity of buckwheat enriched wheat breads were analysed and compared with wheat bread. Wholegrain buckwheat flour contained higher total phenols than wheat flour. The incorporation of buckwheat flour from 15 % to 40 % in bread samples increased the total phenols content from 0.25 (mg GA/g d.m. sample) to 0.65 (mg GA/g d.m. sample), and antioxidant activity from 208.45 (µmol Fe2+/L extract) to 354.45 (µmol Fe2+/L extract). Total phenols content decreased during the baking process, while the antioxidant activity increased. Bread samples with 15 %, 30 % and 40 % of wholegrain buckwheat flour showed lower lightness (L) and whiteness index (WI) values of crust and crumb colour compared to the wheat bread. Addition of buckwheat flour increased redness (a) and yellowness (b) colour values for crumb. Sensory results indicating that three breads with buckwheat flour were moderately acceptable. No differences were found in overall sensory attributes between buckwheat flour enriched bread samples with 15 % and wheat bread (control sample).
