Quality of Flour Types, in the Bakeries of Hamedan, Iran during 2015-2016

Background & Aims of the Study: Wheat flour makes the basic component of bread. Thus,evaluating its quality plays an important role in public health. This paper focused on thephysicochemical and microbial analysis of all bread flour types, used in the bakeries ofHamedan, Iran during 2015-2016.Materials & Methods: All bread flour types such as Barbari, Lavash, Sangak and Tafton breadflours were collected from 100 bakeries which baked various types of wheat bread in Hamedan,western Iran from May 2015 to February 2016 in this cross-sectional study. Moisture, dry matter,ash, fat and protein percent values of samples were analyzed. Total viable counts of bacteria aswell as yeasts and molds of all samples were determined. Identification and characterization ofenumerated fungi was also identified.Results: The highest moisture content percent belonged to Sangak flour (12.75±0.06),significantly (P<0.05) followed by Taftoon (12.57±0.03), Barbari (11.77±0.03) and Lavash(11.57±0.03), respectively. The order of ash percent was as follows: Lavash (1.36±0.01), Sangak(1.11±0.04), Barbari (1.03±0.03) and Taftoon (0.93±0.02). According to the results, Taftoonflour meaningfully (P<0.05) had the highest crude protein value (5.31±0.17%), followed bySangak (4.11±0.03%), Barbari (2.75±0.05%) and Lavash (2.40±0.09%), respectively. Proteinand fat deficiency were observed in all flours. Total viable counts of bacteria were in permissiblerange in all flours. Yeasts and molds of all samples exceeded recommended limits.Conclusion: It was found that the fungal growth control is essential by improving storageconditions, hygienic operations and nutrients enrichment in wheat flours of all bread types ofHamedan, Iran.
