Çimen, Büşra; Yilmaz, Fırat
The objective of this study was to ascertain the distinguishing characteristics of Kürtün-Araköy bread and Gümüşhane bread, two local breads produced in Gümüşhane province in the Eastern Black Sea region. Furthermore, the bread dough samples employed in bread production were subjected to microbiological analyses. It was determined that the number of microorganisms in the sourdough samples used in the production of Gümüşhane bread was high (P<0.001). In this context, breads sold in the Gümüşhane province were collected and subjected to a series of analyses. These included chemical, microbiological, colour and HMF analyses of the bread samples. As a result of microbiological analyses performed on bread samples; It was observed that there were statistical differences in terms of lactic acid bacteria on MRS agar and yeast-mold counts. However, based on the chemical analyses performed on the bread samples, it was determined that there were statistically significant differences between the bread samples. The resulting data were then subjected to statistical analyses, with the objective of determining the differences between the bread samples. This was achieved through the use of PCA analysis, which also enabled the determination of the significance levels of these differences. In addition, the relationship between the colour values of the bread samples and the amount of HMF was also investigated in this study. The findings indicated that as the L* and b* colour values decreased, the HMF content of the bread samples increased. In this study, it was determined that Kürtün-Araköy and Gümüşhane breads have distinctive characteristics.

Güzel, Melih
The short shelf life of bread can be attributed to changes in its textural and sensory properties, a process termed staling, and large amounts of bread residue and waste are generated daily. Because the main component of bread is starch, the use of bread wastes as a substrate for bacterial cellulose (BC) production can significantly contribute to valorisation and reuse of wastes. This study aimed to investigate the BC production potential of various stale breads, convert these wastes into usable forms for food and other industries, and increase their economic value. Stale breads were hydrolyzed with dilute acid, and BC-producing bacteria from Kombucha tea were isolated and identified as Gluconobacter oxydans MG2021 (GO). BCs were produced from bread hydrolysates with GO and Komagataeibacter hansenii GA2016 (KH), and their properties were examined. The results indicated that stale breads represented a good source for BC production, as high BC yields were obtained using GO (8.81%–25.02%) and all BCs had superior properties such as high crystallinity (75.96%–91.39%), thermal stability, liquid holding capacity, and fine fibers (40.16–85.39 nm). This study demonstrated that bread wastes could be used as a low-cost substrate for large-scale BC production, and the abundance of bread wastes demonstrated their potential as a resource for commercial BC producers.

Bu çalışmada Gümüşhane iline özgü Gümüşhane ekmeği ile Kürtün-Araköy ekmeği mikrobiyolojik ve kimyasal analizlere tabi tutulmuş ayrıca ekmeklerin renk analizleri de yapılmıştır. Ekmek hamurlarında yapılan mikrobiyolojik analizlerin sonucu önemli farklılıklar göstermiştir. MRS agarda gelişen LAB sayısı, Araköy ekmeği hamurunda 6.98±0.03 log kob/g, Gümüşhane ekmeği hamurunda ise 8.19±0.07 log kob/g bulunmuştur. Ekmek örneklerinin TAMB sayısı, M17 agarda gelişen LAB sayısı ve koliform grubu bakteri sayısında farklılıklar tespit edilmemiştir. MRS agarda gelişen LAB sayısı, Araköy ekmeğinde 2.45±0.11 log kob/g, Gümüşhane ekmeğinde <2 log kob/g olarak bulunmuştur. Maya-küf sayısı Araköy ekmeğinde 2.27±0.07 log kob/g, Gümüşhane ekmeğinde 2.01±0.01 log kob/g değerinde tespit edilmiştir Ekmeklerin kimyasal analizleri sonucunda Araköy ekmeğinin kül, protein ve titrasyon asitlik miktarları Gümüşhane ekmeğine göre yüksek tespit edilmiş, diğer kimyasal sonuçları (kuru madde, pH) ise daha düşük bulunmuştur. Araköy ekmeğinin titrasyon asitlik miktarı %7.81±0.84 bulunurken Gümüşhane ekmeğinin titrasyon asitlik miktarı %3.88±0.11 bulunmuştur. Protein ve kül miktarları sırasıyla Araköy ekmeğinde %10.95±0.12 ve %1.921±0.021 değerlerinde, Gümüşhane ekmeğinde ise %9.84±0.18 ve %1.734±0.043 değerlerinde bulunmuştur. Ekmek kabuklarının renk analizlerinde Araköy ekmeğinin L ve b değerleri Gümüşhane ekmeğine göre daha düşük tespit edilmiştir.

Hendek Ertop, M.; Ilter, S.M.; YilMaz, F.; BaltaCi, C.; Gündogdu, A.
The aim of this study was to evaluate the effect of the dried sourdoughs produced with two different fermentation methods [Spontaneous fermentation(SPF) and starter of lactic acid bacteria-added fermentation(STF)], and three different drying methods (Drying in oven;DO, Freeze drier;DFD, and Spray drier;DSD) on various quality properties of the wheat bread. The bread samples prepared by addition of the dried sourdoughs at the rates of 3 %, 6 % and 12 %, and control bread prepared without sourdough were compared in terms of bioactivity, shelf life, physicochemical and sensory properties. The addition of the dried sourdough affected the specifc volume, pH and acidity of the bread samples signifcantly (p < 0.05), and a slow down moisture loss occurred during shelf life.The a*value of crust, antioxidant activity, and sensory properties were improved compared to the control bread. The use of dried sourdough at the rate of 12 % gave the most effective results. When the fermentation and drying methods were evaluated together, the combinations of SPF/DO, SPF/DFD and STE/DSD gave the best results.
