Abstract The functional properties, resistant starch (RS), and glycemic index (GI) of fresh noodles substituted with banana flour (BF) were investigated. When the substitution with BF was increased from 0 to 40%, the viscoelastic properties increased, while tensile strength and elasticity decreased from 53.23 to 26.84 gf and 44.65 to 15.04 mm, respectively. GI was reduced from 77.05 to 62.62 while RS content increased from 5.56 to 23.31%. This is considered a very high RS content and the modified noodles are classified as intermediate GI food. Furthermore, the effects of xanthan gum (XG), guar gum (GG), and carboxymethyl cellulose (CMC) individually at 1.0% and 1.5% levels on quality of dried noodles substituted with 30% BF (DBF30) were investigated. DBF30 with XG had the shortest rehydration time (6.5 min), while DBF30 with CMC had the slowest rehydration (8.5 min). The added hydrocolloids increased rehydration and decreased the cooking loss of DBF30, also increasing tensile strength and elasticity of DBF30. Furthermore, the hydrocolloids increased RS content and reduced GI of DBF30. The results reveal that adding BF and hydrocolloids to noodle products provides high nutritional quality with enhanced quality characteristics.
