Due to the water-binding abilities of soy protein and the
potential for the indigestible carbohydrates to increase chyme
viscosity we hypothesized that the soy pretzel would lead to
a higher consumption of water that may contribute to increased
satiety. However, the amount of water consumed was similar
with the consumption of both pretzels.
Conclusion
The addition of 27.2% soy ingredients to a soft pretzel snack food
can significantly decrease the GI without affecting consumer
acceptability or satiety. These results show that it may be
possible to supplement a variety of snack foods with soy at high
enough quantities to achieve lower postprandial glycemia while
maintaining favorable sensory characteristics.
