ABSTRACT
This research work was carried out to determine the functional properties of African yam bean and plantain flour used in the production of cake and cookies using wheat as control. African yam bean and plantain were processed into flours. The flours were used to formulate blends coded S101, S102, S103, S104 and S105 for cake and S106, S107, S108, S109, S110 for cookies. Functional properties, proximate composition and sensory evaluation were carried out on the different blends. The functional properties of the composite flour such as bulk density, oil absorption capacity, water absorption capacity, swelling index and gelation concentration proved their potential use in cake and cookies production. Statistical analysis carried out on the sensory evaluation data showed that the product made from. S101 (100% plantain), S103 (40% wheat, 30% AYB and 30% plantain) and S104 (100% AYB) compare favourable with the control (wheat flour) in the production of cake. While S106 (100% plantain) and S109 (100% AYB) compare favourable with the control (wheat flour) in the production of cookies. Therefore, a little improvement need to be done on African yam bean flour in order to alter the benny flavour that some people did not like. This can be done by researching the appropriate flavour that need to be added to achieve this aim.
