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&#39;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 &ldquo;kabato&rdquo; 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.

Sweet potato (Ipomoea batatas) is a food crop that supplies energy, minerals and vitamins C and B. Some cultivars are very rich in carotenoids (pro-vitamin A). In this study were evaluated and compared the total carotenoids content of two cultivars and the losses on the dehydrated extruded sweet potato flour. Samples from organic and conventional crops were analyzed, in the form of fresh and dehydrated extruded samples. Total carotenoids content of the fresh product, expressed on wet basis, was of 437 µg 100 g-1 for the cream cultivar and 10,12 µg 100 g-1 for the orange cultivar. After dehydration, losses of total carotenoids were of 41% and 38%, respectively. The fresh orange cultivar presented high total carotenoids content in comparison to the cream cultivar. The extruded orange sweet potato flour showed the lowest losses in total carotenoids. Therefore, the processed flour of orange sweet potato could be used to obtain pre-gelatinized extruded flour with high total carotenoids content.
