Sequential thermal priming, retrogradation, and fermentation were combined to transform unripe banana flour (UBF) into a resistant starch (RS) rich ingredient with reduced glycemic impact suitable for pasta manufacture. Three factors: Box- Behnken design (BBD) assessed thermal priming temperature (TPT) (70 – 90 °C), retrogradation temperature (RT) (12 – 38 °C), and fermentation time (FT) (2 – 12 h), with lactic acid bacteria (LAB) strain (Lactiplantibacillus plantarum and Levilactobacillus brevis) as a categorical factor.
