However, the increase in the amount of BF in tested formulations
resulted in decrease of quality of the protein structure which
was manifested as the cracked surfaces of the upper crust of glutenfree
products (Fig. 2).The cracked upper surface was also the only factor which influenced
lower scores for the product appearance, especially for productswithUBF
(Fig. 3). It can be observed that increase in theamount of
UBF in the tested mixtures led to a significant decrease (P 0.05) in
the scores for the appearance which was not the case for HBF containing
systems. In contrast to the crust appearance, the breadcrumb
softnesswas scored withmaximum points for the samples consisted
ofHBFandwithapproximatelyonepoint lower values for the samples
containing UBF. Fine breadcrumb structure which was related to
softness in sensory analysis can also be seen in Fig. 2.
