  • Description: <jats:title>Abstract</jats:title><jats:p>Incorporation of black sorghum flour containing high levels of polyphenols and slowly digestible starch could provide opportunity to enhance nutritional functionality of noodles. Soba‐type noodles were prepared based on a typical wheat‐buckwheat (65:35) formulation by replacement of buckwheat flour with black sorghum flour at 0%, 25%, 50%, 75% and 100%. Noodle colour, texture, total phenolics, antioxidant capacity, <jats:italic>in vitro</jats:italic> starch digestibility and sensory acceptability were evaluated. Increasing the addition of black sorghum flour significantly (<jats:italic>P</jats:italic> &lt; 0.05) decreased the firmness (g) in noodles and imparted a darker colour but increased total polyphenolics and antioxidant capacity. Significantly (<jats:italic>P</jats:italic> &lt; 0.05) lower rapidly digestible starch and higher resistant starch was found in noodles with &gt;50% replacement with black sorghum flour. Overall acceptability of noodles showed preference for noodles containing 25%–75% black sorghum flour. This study demonstrates the potential of using black sorghum as a novel functional food ingredient in noodle manufacturing.</jats:p>
