Formulations consisting of 100% durum wheat semolina (con-trol) and mixtures of semolina:banana flour of 85:15, 70:30 and 55:45 were prepared for spaghetti processing. The homogenised blend was mixed with water (50 ml of water for 100 g of flour) for5 min to allow for hydration, formed, and extruded as spaghetti(1.a-ghetti was cut as it came out of the pasta roller, and dried at 45°C for 4 h in an oven. S 5 mm diameter) using a domestic pasta maker (KitchenAid,Model KPRA, St. Joseph, MI) with a 1 kg dry mix formula. The sppaghetti batches were prepared in duplicate for each formulation. Spaghetti was cooked in boiling water, the cooking time based on the disappearance of the white colour in the pas-ta central core, as evaluated after squeezing the spaghetti between two glass slides. Cooked spaghetti was frozen in liquid nitrogen, freeze-dried,ground using a commercial grinder (Mapisa Internacional S.A. deC. V.; sieve 300 lm) and stored at room temperature in sealed plastic containers.
