The present study investigated the effects of M. domestica and M. oleifera on proximate, functional and sensory characteristics of ‘Baked-gari’ and ‘Boiled-Loi-loi’ products of seven varieties of cassava (M. esculenta). Proximate and functional properties of samples were analyzed using standard methods, while the sensory attributes were done using a nine-point hedonic scale. All fortified products recorded lower values of crude fibre but higher values of ash than their counterpart samples. The value for nitrogen-free extractive determined showed no significant difference between the products. The sensory preference for baked-gari products was according to the decreasing order Ja>Ag.R,> Ag >Ac >Ro and Yo>Og. When compared to the fortified products, the overall acceptability for the sensory tests followed the decreasing order, BAMG > BGV > BMG > BAG, (baked-apple-moringa-gari, baked-gari-varieties, baked-moringa-gari, baked-apple-gari respectively). On the other hand the sensory preference for boiled-Loiloi samples was according to the decreasing order, Og>Ro>Yo>Ja> Ac > Ag >Ag.R. Among the fortified Loi-loi samples AL (Apple-Loi-loi) scored the highest ratings whereas ML (Moringa-Loi-loi) presented the least score in all parameters measured.The functional properties of fortified Baked-gari and Boiled-Loi-loi products had higher values for bulk density and swelling index when compared to their counterpart samples. Promotion of consumption of the fortified products is recommended.
