The aim of the study was to prove the usefulness of texture measurements within the whole
profile of breadcrumb for analyzing its heterogeneity. The breads were baked using the
straight and pre-fermented dough methods. The measurement on the central region (20 mm
thick) breadcrumb was the most suitable for differentiating the breads, but the analysis of
the whole profile (10 mm thick), was the most adequate for breadcrumb texture heterogeneity
quantification. In a majority of the cases breads baked using pre-fermented dough were characterized by better and more homogenous texture in comparison with the straight dough
method. In addition, a general diminishing tendency of breadcrumb hardness and chewiness
was observed together with an increase in flour dry gluten content.
With regard to the above-mentioned information, the assessment of breadcrumb texture
heterogeneity was proposed on the value of measurement variations in the whole
profile of the breadcrumb slice, about 10 mm thickness. The analysis of the variation
coefficients for the individual features of texture permitted us to propose the descriptive
analysis of heterogeneity. The descriptive analysis of heterogeneity was divided into three
intervals (homogeneous, middle homogeneous, and heterogeneous). Determination of the
heterogeneity of texture measurements showed that the studied baking method significantly
differentiated this quality feature of bread. In a majority of cases, the breads baked
using the pre-fermented dough method in comparison to the straight dough method were
characterized by better texture and were more homogenous.
