the effects of hydrocolloid type (guar gum, sodium alginate, xanthan gum) and addition levels (0%, 2%, 4%) onthe retardation of in vitro starch digestibility were investigated in noodles made by various cereal flours (wheat, whole wheat, buckwheat) and their cooking and textural qualities were evaluated. The predicted GI (pGI) of noodles made by wheat or whole wheat flour was significantly decreased by adding hydrocolloids. However, the pGI of buckwheat flour-based noodles with hydrocolloids was slightly increased, Nonetheless, adding hydrocolloids in all noodles positively modified cooking quality regard-less of flour type. The hydrocolloids addition in
