To achieve this, we formulated four different types of pasta with varying levels of incorporation ranging from 10 to 50% cereals such as millet, fonio, and rice, tubers such as manioc and sweet potato, and legumes such as cowpea. The results showed that the incorporation of local products considerably improved the nutrient content of penne without being rejected by consumers. Sensory analysis showed that the best results were obtained with mixtures of sweet potato, cowpea, and wheat, as well as with rice, manioc, cowpea, and sample wheat. These results are of great importance to manufacturers in a world where developing nutritious and attractive food products is a crucial challenge.展开更多

The composite flours were obtained using the Philips mixer type (model HR2811). The nutritional qualities of the formulated flours were determined by the Kjeldahl, AOAC 985-29, UV-VIS spectrophotometry (DR 5000;HACH and LANGE, France) and Soxhlet gravimetric methods. The compounds obtained are respectively: Protein, carbohydrate, lipid, micronutrient and vitamin contents. Monitoring the analysis of functional properties (water and oil absorption capacity) as well as baking value.展开更多

This study aims to assess the consumption, acquisition and supply of cereals to households in the community of Djougou. A semi-directive survey with KoBoCollect was conducted among 369 households to collect individual cereal food consumption data. The survey data processed by statistical tools showed that the most consumed cereals are maize (95%, p = 0.887), millet (58%, p = 0.755), rice (55%, p = 0.753), sorghum (15%, p = 0.635), wheat (5%, p = 0.920) and fonio barely 5%. The most common mode of acquisition in Djougou is purchase (50%, p = 0.947) but donation is also observed (25%, p = 0.988) as well as production observed in 20.6% of households. Purchases are made from retailers in local markets (45%, p = 0.920) but also in streets and alleys (30%, p = 0.765). The most widely used preservation technique is drying at room temperature (70%, p = 0.995). Households most often dry in the areas provided in the field (50%, p = 0.783) and at home (40%, p = 0.643). The preferred storage location is the kitchen (60%, p = 0.790). The bedroom (20%, 0.669) and the store (15%, 0.522) are the alternative places for storing cereals. In addition, the supply costs of cereals increased between 2020 and 2021. This vertiginous rise in prices is due, among other things, to the covid19 pandemic. The various data generated not only make it possible to have fresh data but also to invest them in the assessment of health risks for the achievement of a high level of protection of the health and life of consumers.展开更多
