    In this study, the utilization of LAB (Lactiplantibacillus plantarum, Levilactobacillus brevis, Furfurilactobacillus rossiae, Weissella cibaria) cultures with selected flours of different immature cereal grains (wheat, barley, oat and rye) on sourdough and sourdough bread was investigated. In total, 16 different sourdough breads were produced and microbiological, pH, TTA and rheological properties of sourdoughs at 0, 8 and 24 h were determined. At the beginning of the fermentation, while sourdoughs showed elasticity, they showed viscoelastic properties after 24 h of fermentation. The sugar profile of cereal grains at the stage of milk formation and the sugar groups presented in EPSs isolated from sourdoughs were revealed by HPLC analysis. The sugar groups in sourdoughs were glucose, xylose and arabinose, while the sugars in the immature cereal grains were glucose, fructose and mannose. The highest EPS production level (1882.69 ± 8.16) was observed in immature barley flour and Lpb. plantarum containing sourdough and all sourdoughs were found to contain glucan type EPSs. It was observed that the amount of EPS produced by the related species differed significantly under different grain conditions. Besides, it was observed that the sourdough breads produced were harder than the control bread. Novelty Impact Statement: Wheat, barley, oat and rye immature grains and four distinct LAB strains were used during sourdough fermentation. Immature grain type and LAB strain used were determinants for in situ exopolysaccharide (EPS) production. Viscoelastic properties of sourdough and textural properties of sourdough bread were affected by grains and LAB strain utilized.

    The aim of this study was to determine the physicochemical properties, bioactive substance content, and microbiological quality of sixty different honey samples collected from twelve different regions of Bayburt, Turkey. The samples were analyzed for their sugar, moisture, total phenolic, total flavonoid contents, and water activity, conductivity, pH values and colour, antiradical activity, and DSC properties. As a result of physicochemical analyses, it was determined that the samples examined complied with the standard values defined in the Turkish Food Codex in terms of the parameters examined. The results of the study showed that the total phenolic content (219.43-768.82 mg GAE kg−1), total flavonoid content (31.29-118.7 mg CAE kg−1) and DPPH (12.98%-94.79%) parameters differ widely among the honey samples. A principal component analysis (PCA) was applied to correlate the characteristics of honey with honey samples collected from different regions. This is the first comprehensive and original report about the physicochemical properties of honey produced in Bayburt, a region close to the Anzer region where the most expensive honey, Anzer honey, is produced.
