Abstract: This study was designed to bridge gap in nutritionally skewed available biscuits and the high volume of agricultural waste generated by investigating the quality of biscuits prepared from wheat base, supplemented with waste from watermelon rinds and orange pomace as possible nutritious alternatives. Biscuit samples were respectively produced from blends of wheat, watermelon rind and orange pomace in the following ratio 100:0:0; 90:5:5; 80:10:10; 70:15:15 and 60:20:20, labelled samples A, B, C, D and E. Functional, proximate, mineral and sensory properties of the formulated biscuit samples were carried out using standard analytical procedures. The results showed that proximate composition of samples B - E significantly increased (p There were also significant increases (p < 0.05) in mineral contents of supplemented samples compared to control. The result of the sensory evaluation showed that wheat flour can be substituted with watermelon rind and orange pomace flours up to 10% without adversely affecting the overall quality attributes of the biscuits. These results indicate the robustness of food value addition as an effective means of improving nutritional quality of biscuits while contributing to waste management in the agricultural value chain.
