Abstract
During the last decade the production of white bread was trend in our place but actually recently the consumers show more interest on the quality respectively for nutritive value of food products. Dietary fibers usage is positive since they are reducers of calories, cholesterol in blood, cardiovascular disease and cancer in colon; therefore they are ranking on the top ten functional foods.
Because of the fact that bread is widely consumed in our place the bread is a good dietary fiber supporter, therefore in this study we include the mixture of rice bran in the bread production. Rice bran beside dietary fibers also is rich with essential amino acids especially with lysine, high content of antioxidants, vitamins from B group and minerals. This study provides a mixture of three fractions of the whitening of the rice bran in different proportion, by adding 10% and 15% of these mixtures in wheat flour type 500 in order to produce bread with good technological and health quality. The results have proven that all mixtures have same rheological characteristic, although mixtures with 15% rice bran have proven poor
quality. All the mixtures have optimal maximal viscosity for the actual bread production. Breads from mixtures tagged as 2 1 M and 3 2 M, have very good specific volume and good appearance which is acceptable for the consumers while as all the special (mixed) breads have lower digestibility than the bread produced using wheat flour only.
