The aim of the present study was to prepare and evaluate breads containing various ratios of
gluten-free flours. Corn flour and starch, rice flour and soy meal, as well as a ready mix of
commercial gluten-free meal, were used for the preparation. Also, bread with gluten as
control sample, was prepared using flour for general use. In order to identify differences in
the characteristics of the breads, a qualitative assessment was conducted and maturation in
the oven, bread height, moisture loss, specific volume and yield of the dough were
measured. For the next three days the breads were stored and the course of their moisture
was monitored. In addition, organoleptic evaluation of the breads was performed by 29
unqualified testers, who were asked to evaluate the following characteristics: appearance,
crust color, crumb color, uniformity of crust coloring, uniformity of the crumb porosity,
crumb elasticity, friability, flavor, crumb consistency, crumb crispiness, hardness, chewing
difficulty and overall acceptability. The process was completed with a likeness questionnaire.
Finally, by means of statistical processing, the significance of the effects of the design
parameters on the individual properties of the bread samples was determined. The findings
showed control superiority in the specific volume of the bread, higher crumb moisture
maintenance using a higher soybean meal ratio and an external image similar to that of the
control with the addition of equal proportions of flours. Statistical difference between the
control and the gluten-free samples was observed only in flavor and crumb elasticity. The
largest amount of soy flour showed the most desirable friability and cohesiveness of crumb
and the highest proportion of corn flour, the most desirable hardness, aroma, overall
acceptability and liking.
