NUTRIOSE FB06 fortification to sweet potato flour (SPF) and
starch (SPS) significantly reduced the starch digestibility and glycaemic
index of noodles. Guar gum at 0.5% in SPS noodles and
1.0% in SPF noodles complemented the effect of NUTRIOSE in
enhancing the resistant starch content and further reducing the
GI of noodles. High protein retention in the whey protein fortified
noodles coupled with the low cooking loss made the products well
acceptable with high sensory scores for appearance, flavor and
mouth feel. Slow and progressive starch digestibility indicates
the prospective potential of the products as low glycaemic foods.
