Abstract

n this study, the rheological properties of flours containing wheat bran or dephytinized wheat bran at different rates (0, 5, 10, 15%) and some physicochemical and microbiological properties of bread doughs produced with sourdough by using these flour mixes were investigated. Four different sourdoughs, which were spontaneous (SS), Vakfıkebir (VS), containing Lactobacillus fermentum as
a starter (LFS) and containing Lactococcus lactis as a starter (LCS), were used. The water absorption, softening degree, resistance to extension values of dough increased while the stability, energy and extensibility values decreased as the rate of bran increased for both bran types. The pH and total acidity (TA) values of the bread dough samples generally increased with the addition of bran. The
lowest moisture content, TA and LAB count, and the highest pH and yeast count were obtained in VS. The lowest pH and the highest TA values belonged to the bread dough samples containing SS. The number of LAB and yeast counts in bread dough samples increased with addition of bran compared to control sample.
