The micrographs of FS2 and FS4 reinforced the importance of AF on the quality of the pasta; when the level of AF decreased from 18 to 10 g 100 g1 and the EPP was kept constant at 17 g 100 g1 EPP, the structure was affected and there was not enough EPP to create a regular, compact, and fused surface with a network strong enough to involve the starch granules (Fig. 3B and D, respectively).
