Therefore, the retardation of starch digestibility in noodles made by three different flours from cereals (wheat, whole wheat, and buckwheat) was investigated depending on the type and levels of hydrocolloids (guar gum, sodium, xanthan gum; 2% and 4%). In addition, the cooking and texture qualities of the noodles were evaluated as a function of the nature of flour ans the levels and type of hydrocolloids.
