Noodles are strips or strands cut from a sheet of dough made from flour, water and either common salt or a mixture of alkaline salt. Noodles consumption represents about 40% of the total wheat flour which are mainly consumed by school children. The use of composite flour has been encouraged since it reduces the importation of wheat. Utilization of locally available, inexpensive materials like cocoyam that can substitute a part of wheat flour without adversely affecting the acceptability of the product will be a product development. This study therefore studied the chemical composition and organoleptic properties of instant noodles from the blend of wheat and cocoyam starch. Cocoyam starch was substituted into wheat flour at 20, 40, 60 & 80%. Analysis revealed higher carbohydrate (63.50-70.05)%, moisture (4.54-5.07)% and vitamin A (10.01-30.47) mg/100g, B1 (11.43-32.15) mg/100g but lower protein (4.56-8.79)%, phosphorus (0.34-0.52)%, calcium (1.83-0.98)%, iron (0.15-0.32) % and ash (1.19-3.20)%. The composite noodles revealed higher carbohydrate and mineral but lower protein than the commercial noodles. The sensory analysis revealed that 20% cocoyam compared favourably with the commercial noodles in terms of all the sensory attributes evaluated. This shows the possibility of producing noodles from cocoyam tubers which serves as novel food. This will further help to promote and improve utilization of cocoyam tuber.
