The use of rice/leguminous blend may be nutritionally convenient in gluten free product manufacturing. Gluten free spaghetti was prepared with rice flour and different concentrations of bean flour (included at levels of 0%, 20% and 40%, w/w) derived from a new developed white-seeded low phytic acid and lectin free ( ws + lpa + lf ) bean cultivar. Protein, ash and dietary fibre contents increased linearly ( P < 0.05) while total starch decreased quadratically ( P < 0.05) with the inclusion of ws + lpa + lf bean flour. The colour of spaghetti was influenced ( P < 0.05) by ws + lpa + lf bean inclusion. With respect to 0% spaghetti, the inclusion of ws + lpa + lf bean increased linearly ( P < 0.05) the optimal cooking time and the water absorption capacity, without affecting cooking loss and texture properties. The ws + lpa + lf bean inclusion increases quadratically ( P < 0.05) the resistant starch content, while decreasing quadratically ( P < 0.05) the in vitro glycemic index. The partial replacement of rice flour with bean flour can favourably be used in gluten free spaghetti formulation. [ABSTRACT FROM AUTHOR]
