Abstract :
Flour and bread make up a large part of the table and diet of Iranians. However, the weakness of wheat production in the country is one of the constant problems of the flour and bread industry, which has caused many problems in this industry, and flour mixing is always implemented as the main solution. In the present study, the mixing of strong flour with weak flour in different proportions and its effect on the quality indicators of flour and bread production were investigated. First, samples of 18% flour from the Sardari wheat variety, which is a weak wheat variety, were prepared and in the ratios of 20-80, 30-70, 50-50, 30-70% and 20-80 with 18% flour and strong wheat sample of variety 19. 80N-mixed and rheological and quality indicators (including wet gluten percentage, dry gluten percentage, gluten index, Zelny test, Falling number, ash percentage, moisture percentage, measurement of flour color with image processing technique) And the results showed that the treatment of mixing 70% of weak flour with 30% of strong flour due to the high level of all indicators related to flour and bread, including dry and wet gluten percentage, gluten index, Zelani and Falling number, ash percentage, moisture and protein, texture, aroma and smell, chewability, porosity, appearance and color indicators of bread, compared to other mixes, and also no significant difference compared to mixes with a higher percentage of strong flour can be suggested as the best mix.
