Roasting Time

This study used Response Surface Methodology was used to roast, identify and characterize the optimum values of functional properties of African breadfruit (Treculia africana) seed flour processed for industrial applications. The central Composition Rotable Design of treatment variables at 3 process variables (Roasting temperature RT, Roasting Time RM, and feed quantity FQ) and 5 process levels (-1.682, -1, 0, 1, 1.682) was used to optimize bulk density water and oil absorption capacities, gelation and emulsion capacity of the produced flour. Functional properties of the flour increased above the value of control and relative to process treatment. The effect of roasting temperature was significant (p < 0.05) for bulk density, gelation and emulsion capacity. Roasting time and feed quantity significantly (p˂0.05) influenced water absorption and emulsion capacities of the flour. Optimum values were bulk density 0/79 g/cm3, water absorption capacity 4.00ml/g, oil absorption capacities 2.90m/g, gelation 8.92 w/v. The unified optimum values of the functional properties occurred at process treatment combination of 126.360C, 45.85min and 505.09g, respectively for temperature, time and quantity. Processing African breadfruit seeds into flour at the optimal point will enhance its usefulness in industrial applications were functional properties of flour are of processing important.

Ogi was produced from composite flour of fermented Acha, roasted Soybean and Carrot.  The raw materials were blended in varying proportions. Proximate composition, functional properties and sensory characteristics of the formulated Ogi samples were evaluated. The results of the proximate composition showed a significant increase in moisture (5.36% to 9.94%), protein (3.94% to 16.98%), fat (1.89% to 10.23%), crude fiber (1.80% to 3.12%) and ash (0.35% to 0.99%); while a decrease was observed in carbohydrate (86.66% to 58.74%) with increase in supplementation with roasted Soybean flour and constant addition of carrot flour along with the milk flavor. The functional properties showed significant increase in foam capacity (5.99% to 7.97%), Swelling index (2.46 v/v to 3.08 v/v) and Least gelation capacity (8.10% to 14.0%); while a decrease was observed in bulk density (0.84 g/mL to 0.72 g/mL), water absorption capacity (1.40% to 1.10%) and foaming stability (3.39% to 2.79%). Sensory characteristics result revealed that there was no significant difference (p<0.05) in aroma and overall acceptability with increasing incorporation of roasted Soybean flour and constant addition of Carrot flour with milk flavor. Aside the control sample (containing 100% fermented Acha flour) there was preference for Sample C (70% fermented Acha flour: 15% roasted Soybean flour: 10% Carrot flour: 5% Milk flavor) and Sample D (60% fermented Acha flour: 25% roasted Soybean flour: 10% `Carrot flour: 5% Milk flavor) in terms of color (6.65 and 6.25), taste (6.95 and 6.35), aroma (6.45 and 6.30), mouth feel (6.10 and 6.35) and overall acceptability (6.50 and 6.50) respectively, among the blend formulations. Supplementation of fermented Acha with roasted Soybean and Carrot flour considerably increased the protein and fat contents of the blend; hence Soybean should be used for supplementation of cereal based product in order to improve their nutritional composition.
