The hydrolysis index (HI) was calculated by dividing the area
under the hydrolysis curve (0–180 min) of the sample by the corresponding
area obtained for the reference sample (white bread)
over the same duration (Goni, Garcia-Alonso, & Saura-Calixto,
1997). The glycemic index (GI) of the sample was estimated
according to Granfeldt, Björck, Drews, and Tovar (1992) as given
in Eq. (1):
GI ¼ 8:198 þ 0:
