“…Phytic acid was reported to chelate several elements such as Zn, Fe, Ca and Mg in its dephosphorylated form (Feil 2001) by interfering with their absorption (Ologhobo 1980). The divalent minerals were reported to move to middle lamella of cell wall after getting released from phytate-mineral complex (Phillips et al 2003), and form insoluble pectate complex by replacing monovalent minerals (Mattson 1948). This may prevent cell separation during cooking, hence contributing towards the HTC defect.…”

The present study was aimed to evaluate the differences among anti-nutritional factors in relation to mineral absorption and protein digestibility of Easy-tocook (ETC) and Hard-to-cook (HTC) grains from different kidney bean (KB) accessions.HTC grains showed lower a* (redness to yellowness) and b* (greenness to blueness) values and L* value than ETC grains. HTC grains had significantly higher Ca and Zn and lower Cu, Mn and Fe than ETC grains. ETC and HTC grains showed significant variation in mineral, total phenolic content (TPC), tannin and phytic acid content. TPC and tannin content were significantly higher for HTC grains, on the contrary phytic acid content was lower than counterpart ETC grains. Protein and in vitro protein digestibility (IVPD) also varied significantly between HTC and ETC grains and was found to be lower for HTC grains. Majority of phenolic compounds (PCs) were present in bound state in both ETC and HTC grains. Moreover, HTC grains showed higher amount of chlorogenic acid and catechin content than ETC grains in bound form. ETC and HTC grains from dark color accessions showed higher catechin content.

“…is one of the most important legume species used in human food and animal feed and is largely cultivated in semi-arid regions due to its broad adaptability and low water and nutrient requirements (Agele et al 2006;Manivannan et al 2007;Barbosa et al 2013). The grains represent the focus of this culture, with socioeconomic importance due to their high content of proteins, carbohydrates, vitamins, and minerals, such as phosphorus and potassium, compared with other legumes (Phillips et al 2003;Iqbal et al 2006;Frota et al 2008). Water deficit is considered the main abiotic stress that limits agricultural production worldwide (Inman-Bamber and Smith 2005).…”

Water deficit is considered the main abiotic stress that limits agricultural production worldwide. Brassinosteroids (BRs) are natural substances that play roles in plant tolerance against abiotic stresses, including water deficit. This research aims to determine whether BRs can mitigate the negative effects caused by water deficiency, revealing how BRs act and their possible contribution to increased tolerance of cowpea plants to water deficit. The experiment was a factorial design with the factors completely randomised, with two water conditions (control and water deficit) and three levels of brassinosteroids (0, 50 and 100 nM 24-epibrassinolide; EBR is an active BRs). Plants sprayed with 100 nM EBR under the water deficit presented significant increases in U PSII , q P and ETR compared with plants subjected to the water deficit without EBR. With respect to gas exchange, P N , E and g s exhibited significant reductions after water deficit, but application of 100 nM EBR caused increases in these variables of 96, 24 and 33%, respectively, compared to the water deficit ? 0 nM EBR treatment. To antioxidant enzymes, EBR resulted in increases in SOD, CAT, APX and POX, indicating that EBR acts on the antioxidant system, reducing cell damage. The water deficit caused significant reductions in Chl a, Chl b and total Chl, while plants sprayed with 100 nM EBR showed significant increases of 26, 58 and 33% in Chl a, Chl b and total Chl, respectively. This study revealed that EBR improves photosystem II efficiency, inducing increases in U PSII , q P and ETR. This substance also mitigated the negative effects on gas exchange and growth induced by the water deficit. Increases in SOD, CAT, APX and POX of plants treated with EBR indicate that this steroid clearly increased the tolerance to the water deficit, reducing reactive oxygen species, cell damage, and maintaining the photosynthetic pigments. Additionally, 100 nM EBR resulted in a better dose-response of cowpea plants exposed to the water deficit.

“…Cowpea grain contains about 25% protein, making it extremely valuable where many people can't afford proteins from animal sources such as meat and fish [1,2]. Cowpea flour has been used as a nutritious ingredient in fried and baked products, as well as comminuted meat products, such as chicken nuggets and meatballs [3][4][5][6]. Sweet potato (Ipomoea batatas L.) is an important sources of calories for the people of the developing nations; is the seventh most important food crop grown in around 111 countries with 80% of the world production came from China, where the roots of sweet potato are used as food or as raw material for starch and noodle manufacture [7,8].…”

Cowpea and sweet potato were used for their nutritional and functional properties; thus the objective of this study was to determine the physicofunctional and sensory properties of cowpea flour based recipes (akara) and incorporated with sweet potato. Moisture, protein, fat, ash, and carbohydrate were in the range of 7.33 to 9.75, 11.66 to 20.98, 1.51to3.49, 2.48 to 2.73, and 65.38 to 76.28% respectively. Water and oil absorption capacities ranged between 1.64 and 2.52 and, 1.67 and 2.04 g/g, respectively. Bulk density and water solubility ranged between 0.86 and 0.90 g/mL, and 1.19 to 2.01 g/100g respectively. Lowest swelling power was recorded for cowpea flour while the highest value was observed for the composite cowpea-sweet potato (50-50%) flour. The overall acceptability of the akara sensory properties was the 90-10% composite. The results indicated that the addition of sweet potato in making akara had significant effect on its properties
