. The addition of 15% maltodextrin reduced the moisture uptake by 45% to samples conditioned at 44%RH. At low moisture contents, the ALS become crispy. The crispness was lost as the moisture content of samples increase, following the modified Fermi equation behavior. The transition from crispy to soft material occurred at a water activity between 0.22 and 0.44. Addition of 15% maltodextrin increased the puncture force, puncture deformation and maximum amplitude up to 143%, 35% and 140% respectively. The variation of molecular weight and moisture content of snack products creates different texture and sensations at biting and chewing.
