Method Analysis

The good use of food is one of the fundamental points of the food security of the populations especially in the developing countries. Therefore, for convincing results, the methods of strengthening nutritional knowledge by improving the culinary practices of vulnerable populations must take into account the dietary habits of the targets. The objective of the present study was to contribute to the consumption of the project crops to develop food formulations. In practice, eight (8) cornmeal formulas using soybeans and orange-fleshed sweet potatoes have been proposed and submitted to the grantees. The different proportions of ingredient to be mixed were obtained by the Pearson's Square method. Analysis of the sensory evaluation data was possible to the Statistical Package for Social Sciences (SPSS) software version 21 and the different results were presented in the form of radar graphs. The results showed that simultaneously flours and “kabato” accepted by the populations of the study area were formulations of: - E: 72.26 percent of maize flour and 27.74 percent of sweet potato flour - F: 53.76 percent of corn flour and 46.24 percent of sweet potato flour - G: 89.3 percent of composite flour (maize and sweet potato) and 10.7 percent of soya flour - H: 78.09 percent of composite flour (maize and sweet potato) and 21.91 percent of soya flour So, it can be envisaged to implement a strategy for a better vulgarization of these methods.

Application of wheat flour in various food products has increased the import of wheat flour over years. The use of domestically grown crops like Sorghum (Sorghum bicolor L. Moench) could reduce the demand of wheat. Sorghum flour can be used in partial substitution with wheat flour for many food products, like cookies. The use of sorghum as cookies ingredient could be combined with other flours to get a composite flour. The purpose of this research was to obtain proportion of sorghum flour, sweet potato flour and soyabean flour that produce cookies with good organoleptic characteristics. The proportion of composite flour adequacy was calculated using a list of foodstuffs (DKBM).The research method was based on Experimental Method with Randomized Block Design (RBD) in twelve treatments and two repetitions. The treatments were proportion of sorghum flour (6 minutes, 8 minutes, 10 minutes of dehulling time), sweet potato flour, and soyabean flour. The results showed that cookies made with proportion of sorghum flour, sweet potato flour, and soyabean flour gave no significant difference in organoleptic characteristics (Overall, color, taste, aroma, and hardness).  The result also showed that the characteristics of the cookies were not affected by dehulling of sorghum grains but influenced by other ingredient than flour. Keywords: Sorghum, Sweet Potato Flour,  Soyabean Flour, Cookies, Sensory Properties

Consumption of fast food continuously can be detrimental to human health. An effective solution is to make innovative food that is able to meet the adequacy of nutrition, one of which is foodbar. The raw materials used in the manufacture of foodbar come from local commodities which are flourished, including sweet potatoes, green beans and Moringa and added porang to unite the three ingredients. Yellow sweet potato flour contains 77.7% carbohydrates with high digestibility (98%), while Moringa leaf flour contains 27.1 grams / 100 grams protein. Mung bean flour is used as a flavoring agent, while porang flour which is rich in glucomannan acts as a binder agent to produce foodbar products that are not easily destroyed. The treatment in this study used two factors, namely the composition of the composite flour and the composition of the addition of porang. Observations made include physical properties including water content, volume expansion, kamba density and texture of the foodbar. The best treatment on the foodbar was the combination treatment of 100 grams of yellow sweet potato flour (40 grams) green bean flour (60 grams) moringa leaf flour and (4%) porang (P3T1).

Aims: The aim was to produce of ready-to-eat breakfast cereals from blends of local rice (Oryza sativa), malted African yam-bean and orange- fleshed sweet potato [Ipomoea batatas (L) Lam.] (umusco/3 variety) flours as well as to evaluate the nutritional properties, microbiological quality and sensory attribute of the formulated breakfast cereals. Study Design: The experimental design that was used is Completely Randomized Design. Place and Duration of Study: The study took place at the Department of Food Science and Technology, University of Nigeria, Nsukka between December 2016 and September 2017. Methodology: The study investigated the application of local rice, malted African yam bean and orange-fleshed sweet potato flour to develop ready-to-eat breakfast cereals rich in proteins and pro-vitamin A. The local rice and malted African yam bean flours were blended in the ratio of 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 to produce ready-to eat breakfast cereals which was subjected to sensory evaluation to isolate the best blend (90:10). From the preliminary study, composite flour was formulated by mixing rice flour and African yam bean flour from the best blend in different percentages. Samples of ready-to-eat breakfast cereals were formulated by mixing composite flour (rice and African yam bean best flour blend) with graded levels of orange fleshed sweet potato and 100% rice flour was used as the control sample. The breakfast cereal products were subjected to proximate, pro-vitamin A, microbiological and sensory analysis using standard methods. Results: The protein, ash, fiber and moisture contents of the blends (rice/African yam bean best blend +orange-fleshed sweet potato flours) were significantly (p<0.05) higher than the control but their carbohydrate content were lower than the control. The protein content, fat, ash, crude fiber, moisture, and carbohydrate contents ranged from 6.82(100% rice flour) to 11.21%(90% rice/African yam bean best blend+ 10% orange-fleshed sweet potato flour), 0.20(50% rice/African yam bean best blend+ 50% orange-fleshed sweet potato flour) to 1.21%(90% rice/African yam bean best blend+ 10% orange-fleshed sweet potato flour), 4.03(100% rice flour) to 15.81% (50% rice/African yam bean best blend+ 50% orange-fleshed sweet potato flour), 1.31(100% rice flour) to 2.80% (50% rice/African yam bean best blend+ 50% orange-fleshed sweet potato flour), 6.61(100% rice flour) to 10.92% (50% rice/African yam bean best blend+ 50% orange-fleshed sweet potato flour) and 63.07(50% rice/African yam bean best blend+ 50% orange-fleshed sweet potato flour) to 80.22% (100% rice flour) respectively. The pro-vitamin content of the samples ranged from 0.13 (100% rice flour) to 2.55 mg/100 g (50% rice/African yam bean best blend+ 50% orange-fleshed sweet potato flour). There was an increase in the pro-vitamin A content as the ratio of orange-fleshed sweet potato increased in the blend. The total viable count ranged from 3.0 × 103 to 6.7 × 103cfu/g while mould was not detected in any of the samples. The microbial content of the samples were satisfactory and not high when assessed using the guideline for microbiological quality of cereal products. The sensory evaluation conducted showed that among the six ready-to-eat breakfast cereals, 100% adani rice breakfast cereals, samples RAYBF1+OPF1 and RAYBF5+OPF5 were highly accepted. Conclusion: The study has shown that acceptable ready-to-eat breakfast cereals could be produced from blends of Adani rice, malted African yam bean and orange flesh sweet potato flour. Among the different breakfast cereals, 100% adani rice and sample RAYBF1+OPF1 (90 % best blend + 10% orange flesh sweet potato flour) were highly accepted.
