The physical properties of the dough, stickiness and extensibility, measured for the different salt contents are reported in Table 1. The adhesive work decreases significantly as soon as a small amount of salt is added (0.35% d.b.), then it keeps on decreasing but less significantly. Therefore a salt reduction of 25% (salt content of 1.58% on a flour basis) does not affect the stickiness of the dough. Regarding the extensibility, a significant and linear increase (R2 = 0.91) of the resistance to extension Rmax is measured, from 222 mN to 518 mN, when the salt content of the dough (recipe 1 without fat) is increased from 0% to 2.1% respectively. These results consolidate previous works of Beck et al. (2012) and Casutt et al. (1984), and are in agreement with the hypothesis of a strengthening of the protein network in the presence of salt (Chiotelli et al., 2004, McCann and Day, 2013 and Tolstoguzov, 1997). However, in spite of a significant effect of the salt on the resistance to extension Rmax, no trend can be highlighted from these results on the extensibility value Emax.
