Hydrolysis indices (HI) calculated from the hydrolysis
curves, and corresponding pGI are presented in Table 4.
HI for bakery products with MDF was similar. Control
cookie showed a slightly lower HI than control bread, a
result that may be consequence of the different physical
structure of both items (Bello-Pe´rez et al., 2004; Granfeldt
et al., 1992). Interestingly, HI for control products did not
differ much from those reported for corn tortillas (77.6%),
tested with the same experimental procedure (Sa´ yago-
Ayerdi et al., 2005). HIs and derived pGIs for products
containing MDF were lower than those determined for
their respective control samples, indicating that this fibre
exerts a significant effect on the rates of digestion and
absorption (simulated by the dialysis phase) of the starch
