Physical, chemical and sensory properties of cookies produced from sweet potato and mango mesocarp flours

Abstract

This study was a result of the need for utilization of local raw materials for food production and diversification as well as an attempt to reduce the rising cost of wheat imports. The objective of this study was to investigate the physical, chemical and sensory properties of cookies produced from sweet potato and mango mesocarp composite flours. Sweet potato tubers and partially ripe mango fruits were processed into flours. Cookies were prepared from blends of 90:10, 80:20, 70:30 and 60:40 sweet potato flour (SPF) to mango mesocarp flour (MMF), with cookies prepared from 100% sweet potato flour (SPF) and 100% wheat flour (WF) serving as control and standard respectively. Thereafter, all the cookie samples were subjected to chemical, physical and sensory analyses using standard methods. The moisture, fat, fibre, ash, energy values as well as beta carotene contents increased significantly (p
