The effect of replacing wheat flour with different kinds of wheat bran and spelt bran at level 5, 10 and 15 % on dough rheology, qualitative parameters of cookies as well as on sensory properties was studied. Addition of bran increased water absorption and mixing tolerance index, prolonged dough development time and decreased dough stability. It was also observed that incorporation of wheat bran modified qualitative parameters of cookies (volume, specific volume, spread ratio and porosity decreased). From the sensory evaluation resulted that higher amounts of wheat bran negatively affected taste, hardness and overall acceptability of cookies. Addition of bran up to 5 % resulted in cookies with high overall acceptability.

Improving the micronutrients in food has become an important field of the Second Green Revolution. In recent years, minor bioactive compounds such as polyphenols, pigments and carotenoids, have attracted more and more interest from both researchers and food manufactures as health-promoting and disease-preventing effects in both in vitro and in vivo studies. One of plant pigments, wheat anthocyanins as plant phenolics are increasingly attractive as natural compounds positively affecting consumer´s health and condition moreover wheat is staple food source consumed usually daily. For a purple, blue, or red colour of wheat seed are responsible glycosylated cyanidins, delphinidins, malvinidins, pelargonidins, petunidins, and peonidins located in aleurone layer or pericarp, respectively. Other than white seed colour is not natural for common hexaploid wheat but this trait can be introduced from donors by aimed breeding programs. The way of wheat anthocyanins to provide positive effects for consumer´s physiology is limited due to their specific occurrence in seed parts usually removed during grain milling practice and lower stability during processing to foods
