This study evaluated the effect of bambara groundnut supplementation on the physicochemical properties of local rice flour and baked crackers. Bulk and true density, porosity, water absorption index, oil absorption capacity, pasting properties by RVA, morphological appearance by SEM, color by calorimetry, and textural properties by TA.XT2 analysis of wheat and two formulations of rice-legume flours and crackers were studied. Moisture (10.94%) and carbohydrate (77.42%) levels were significantly greater in wheat flour than the rice-legume flours, while the reverse was true for fat and ash. Also rice-legume flours had significantly greater water and oil absorption capacity and lower water solubility compared to wheat flour. Compared to wheat crackers, rice-legume crackers had greater fat and ash, 20.51 and 3.57%, respectively, while moisture was significantly lower in the rice-legume crackers by 41 to 58%. Rice legume crackers were significantly harder and had significantly increased spread ratio. The results obtained from the development of locally grown rice and underutilized legume bambara groundnut showed great promise in physicochemical and functional properties and may be a good replacement for wheat flour to serve as a gluten-free product.

This study investigates the nutritional and anti-nutrient profiles of extrudates produced from seven formulations of pearl millet and Bambara groundnut flour in seven different ratios: 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, and 80:20, with 100% pearl millet and 100% Bambara groundnut extrudates used as controls. The extrudates were processed using a twin screw extruder and analyzed for their nutritional and anti-nutritional properties. The findings revealed a rising pattern in the content of fiber, moisture, protein, ash and fat as the substitution of Bambara groundnut increased in the extrudate.

The development of alternative proteins derived from fungi-based sources is gaining recognition due to their health benefits and lower environmental impact, compared to traditional animal-based sources. In this study, we investigated the culture conditions for mycelia, focusing on the nutritional requirements and yield optimization using solid surface culture and liquid-state culture methods. Our findings indicate that optimal culture conditions involve glucose as the primary carbon source, with an initial pH of 6.

In sub-Saharan Africa, the parasitic is seriously threatening Bambara groundnuts, farmers to suffer yield losses of up to 100 %. The objective of this study was to determine the effects of phosphorus (P) application and inoculation on Bambara groundnut genotypes for growth and reproductive phrase. The experiment was conducted in 2020 at the Henderson Research Station in Mazowe, Zimbabwe in a 2 × 2 × 26 factorial design with 26 genotypes arranged in a completely randomized design (CRD) with four replications, two P rates (0 and 20 kg ha-) and two levels of inoculation (with and without ).

Background Voandzou and cowpea are two legumes commonly used in African dishes as alternative sources of proteins. The present study aimed to evaluate the effects of steaming and frying on the nutritional and functional properties of Cameroonian cowpea () and Bambara groundnut (). Methodology The nutritional values, as well as the antioxidant, alpha-amylase, and alpha-glucosidase inhibitory activities of "koki" and "beignet koki," which are the traditional steamed dish and fritters made from cowpea and Bambara groundnut, respectively, were assessed.

Article Synopsis
- Heat treatment of Bambara groundnut seeds lowers the paste viscosities of resulting flours by causing structural changes in the protein that encapsulate starch.
- Trypsin hydrolysis of these proteins leads to the visible separation of starch granules and significantly increases paste viscosities from 733.9 mPa s to 2081.71 mPa s.
- The study also finds that combined microwave and infrared heating alters the protein's secondary structures, increasing β-sheet content while decreasing α-helix, impacting the flour's overall properties.
