Abstract
The technological properties, mineral contents, in vitro mineral bioavailability, and glycemic index (GI) values of breads made from whole wheat flours of colored wheats (red, purple, blue, and black) were evaluated. Purple wheat had the highest Farinograph stability, while black wheat showed a higher water absorption value, indicating superior rheological properties. The symmetry and crumb cell structure of whole wheat breads made from blue and black wheats were significantly (p
