Commercial fresh spaghetti made with wheat flour (Fig. 3H)
showed cracks, unlike spaghetti formulated with DPP, EPP and AF,
which did not have this characteristic at 300 magnification. This
finding indicated that the network of experimental spaghetti had
better resistance to drying (this analysis was performed using dry
samples), suggesting the potential application of these raw materials
to the production of dry pasta. Fig. 3H shows that the wheat
flour granules were smaller than the DPP granules. High relief
starch granules were observed; however, these granules seemed to
be covered by a film most likely formed by the network of gluten,
egg proteins and/or lipids, which were added to the formulation
and listed in the commercial pasta label. Chen, Schols, and Voragen
(2003) demonstrated that the size of the starch granule has a
relationship with the processing and quality of the pasta.
