Aim: To evaluate the proximate composition, functional and sensory properties of a complementary food from pearl millet, soy flour and baobab fruit pulp composite flours. Study Design: A complementary food was produced from Pearl millet, soy flour and baobab fruit pulp powder (BFP) of various proportions (10, 20, 25 and 30%). Proximate (protein, ash, moisture, fibre, fat, carbohydrate and energy value) composition, functional (Bulk density, gelation capacity, swelling index, water absorption capacity and oil absorption capacity) properties and sensory (appearance, flavour, texture and overall acceptability) attributes were determined. Results: The results of proximate composition showed that Moisture content ranged from 10.09 – 10.98, Protein content ranged from 9.80 – 24.25, Fat content ranged from 4.94 – 16.65, Carbohydrate content ranged from 43.11 – 71.03, Fibre content ranged from 3.37 – 15.67, Ash content ranged from 2.59 – 2.87% and Energy value ranged from 367.78 – 423.69 Kcal. The functional properties showed that Water Absorption Capacity ranged from 2.70 – 2.91, Oil Absorption Capacity ranged from 1.90 – 2.72, Bulk Density ranged from 0.69 – 0.71, Swelling Index ranged from 0.68 – 1.04 g/ml and Gelation Capacity ranged from 5 – 10% of the complementary food samples. The sensory attribute also revealed that the complementary food samples proved to be of good quality but the controlled sample (A) was most preferred by the panellist. Conclusion: It could be concluded that the Complementary food was produced from millet, baobab fruit pulp and soy flour. Though, samples were found to be low in protein, fat and energy. The carbohydrate, fibre and ash contents were found to increase with increase in baobab fruit pulp addition. Gelation capacity, swelling index and Oil absorption capacity increase with addition of baobab fruit pulp. On the other hand the bulk density and water absorption capacity decrease with increase baobab fruit pulp addition. The sensory properties indicated that sample A was the most preferred sample.
Aim: To evaluate the Quality characteristics of Bread produced from Wheat and Kidney Bean composite flour blend. Study Design: Composite bread was produced from wheat and kidney bean flour of various proportions (10, 15, 20 and 25%). Proximate (protein, ash, moisture, fibre, fat and carbohydrate) composition, functional (Bulk density, foaming capacity, swelling index, water absorption capacity and oil absorption capacity) properties and sensory (appearance, taste, flavour, texture and overall acceptability) attributes were determined. Results: Bread was produced from wheat and kidney beans composite (B, C, D and E) flour. The bread samples were subjected to physical, proximate and sensory analyses. The functional properties of the composite flour blends were also determined. The functional properties shows a significant (P<0.05) difference in water absorption capacity, oil absorption capacity and swelling index with values ranged from 1.10 – 0.60 ml/g, 1.03 – 0.76 ml/g and 5.92 – 2.89 ml/g respectively. The bulk density and foaming capacity shows significant (P<0.05) difference with its values ranging from 0.90 – 0.97 g/ml and 32.69 – 26.94 cm3 respectively as kidney beans flour increases. The result of the physical properties shows significant (P<0.05) difference in dough height, proofing rate, loaf volume, specific volume, baking loss and oven spring with values ranging from 1.169 – 3.39 cm3, 0.01 – 0.02 cm3/min, 0.79 – 1.19 cm3, 0.32 – 0.48 cm3/g, 1.59 – 2.79 and 101.58 – 102.79 respectively while the loaf weight ranged from 243.21 – 246.09 g. proximate composition of the sample were also analyzed and the result shows significant (P<0.05) difference in crude protein, moisture content, ash, crude fat, crude fibre and carbohydrate with values ranging from 8.36 – 10.47%, 22.18 – 23.28%, 0.97 – 1.38%, 11.80 – 12.94%, 0.29 – 0.59% and 51.33 – 57.10% respectively. The results of the sensory scores shows a significant (P<0.05) difference in all the samples analyzed. However, sample C with 15% kidney beans flour was most preferred. Conclusion: It could be concluded that increased in kidney beans flour addition in the production of composite bread had significant (P<0.05) impact on the proximate, physical and organoleptic properties of the bread. Hence, 85% wheat to 15% kidney bean flour should be used in bread making.
Aim: To investigate the effect of yeast addition and proofing time on the quality characteristic of bread from wheat and cassava flour. Study Design: Composite flour of wheat and cassava was prepared in a ratio 70:30% from which sample B, C, D, E, F, F, G, H, I and J were obtained. Each of the samples was treated with 3, 6 and 9 g yeast concentration at different proofing time of 60, 90 and 120 minutes respectively. The samples were further subjected to analyses of proximate composition, vitamins and sensory properties to ascertain the quality to wheat-Cassava flour. Results: The result revealed a significant (P< 0.05) increase in proximate composition as Protein content range from 13.
