Nowadays the nutritional specifications of wheat bread have been more considered, this purpose would have done by mixing different materials with wheat flour. The bran is one of the materials that had more been considered by researchers, due to its nutritional and technological properties. Therefore, in current research, the effects of adding different percentages of bran (10 and 20 percent) with different particle sizes (tiny and coarse) on the sangak bread was evaluated. The rheological properties of dough investigated by the farinograph and extensograph and textural properties of bread analyzed using texture analyzer. The results revealed that adding wheat bran resulted a decrease in weight loss and an increase in moisture content of sangak bread. Adding wheat bran increased the water absorption capacity up to 11.35%. The elasticity of dough in samples containing wheat bran varied from 74.87 to 112.62. Dough samples made from whole flour had the highest amount of consistency with 337.5 BE in 50mm. Hardness of bread with 20 percent of tiny bran was 4132g that was the highest comparing with other sangak bread samples. Sensory scores showed that sangak bread made from flour formulated with wheat bran have not been taken into consideration by the panelists group, although adding wheat bran due to better technological properties.

According to the growing trend of consumption of artificial colors in the food industry as well as their destructive effects on public health, information on the type and consumption of artificial colors which are allowed, as well as increasing the health and safety knowledge of producers and sellers of food. And frequent monitoring by health officials is essential. Therefore, in this study, the status and frequency of synthetic dyes (Sunset Yellow, Tartrazine, Quinoline Yellow and Carmoisine, etc.) in food supplied in Torbat-e-Heydarieh city was investigated using thin layer chromatography method. In current study, 251 samples including processed chicken, Zoolbia and okra, various types of sweets and traditional ice cream were analyzed. Among 66 processed chicken samples, 11 samples had no color, 6 samples had natural color and 50 samples had artificial color which among those that found synthetic dyes, the prevalence of tartrazine and sunset yellow were higher. Among 70 samples of zoolbia and okra, 32 were colorless, 4 and 34 samples had natural and synthetic dyes, respectively, that using of tartrazine, sunset yellow and quinoline yellow was higher than the others. Among 90 samples of sweets which were investigated, 6 samples were colorless, 2 and 82 samples had natural and artificial colors, respectively, which sunset yellow, tartrazine and carmoisine were more common. Finally, among 25 ice cream samples, 15 samples had natural dyes and 10 samples had artificial dyes, that sunset yellow, tartrazine and carmoisine were common than the others.

Bakery products that contain main part of food process industries usually made with wheat flour and establish a stable gluten network when mixed with water. Although presence of gluten proteins in wheat flour is a unique property, but substituting of wheat flour with other cereal grains up to a certain limit is possible. In current research three different millet varieties namely Proso, Pearl and Foxtail millet were used. Millet flour was used in proportions of 10, 30, 50 and 100% in replacing wheat flour in a cake recipe. Sensorial properties, textural attributes and color indices were evaluated. Results showed that increase in millet concentration in cake formulation decreased the efficiency properties of cooking of dough. Cake height decreased with increase in millet concentration in dough. Pearl millet showed a better cake volume in comparing with the two other millets. Cake cohesiveness decreased with increase in millet substitution and these variations was the same for all varieties. Millet composition in dough decreased adhesiveness of the product. Cakes with higher millet composition showed higher hardness. Totally, Pearl millet produced better cakes in comparison with Proso and Foxtail millets. Total acceptability of millet cakes obtained higher scores at sensory analysis. Considering all characteristics used in current study, 30% substitution level suggested as the best substitution level. The results of current research are valuable at bakery products containing millets.
