Borassus aethiopum (African palmyra palm (APP)) fruit is an underutilized tropical fruit but has potential food applications. In the present work, the suitability of APP fruit–wheat composite flour in the development of noodles was investigated. The fresh APP fruit pulp was separated, oven-dried at 60°C and milled into flour. The obtained flour was mixed with commercial wheat flour to obtain three composite flours with 5%, 10% and 15% of APP fruit flour. The functional properties and proximate composition of the composite flours were determined. The cooking properties and consumer preference of the noodles developed were also evaluated. The cooking yield, water uptake and gruel solid loss ranged from 259.81% to 300.97%, 159.81% to 200.97% and 11.52% to 17.11%, respectively. The water absorption capacities, swelling power and the solubility indices of the flours ranged from 197.10% to 492.66%, 621.99% to 734.91% and 4.53 to 26.48%, respectively. On the 7-point hedonic scale, the flavour, smell, colour and overall acceptability ranged between 4.2 and 5.3, 4.8 and 5.65, 4.05 and 5.3 and 4.10 and 5.03, respectively. The inclusion of APP fruit flour at 5% level yielded noodles with enhanced nutritional quality and highest overall consumer acceptability.
