“…The range of values we observed for iron (4.9–8.2 mg/100 g d.w) and zinc (2.7–4.1 mg/100 g d.w) were somewhat lower than the 5.6–10.4 mg/100 g d.w and 3.7–5.4 mg/100 g d.w respectively observed among cowpea landraces in Benin [37]. Based on iron and zinc concentrations the results suggest that zanzi zee could be promoted as the most suitable landrace with the potential to improve iron intake.…”

“…Based on iron and zinc concentrations the results suggest that zanzi zee could be promoted as the most suitable landrace with the potential to improve iron intake. However, the phytate and polyphenol concentrations of the landraces were high but within range of values reported by Madode et al [37]. Iron and zinc absorption are partly influenced by phytate and polyphenol concentration [35], [38].…”

Cowpeas in Northern Ghana and the Factors that Predict Caregivers’ Intention to Give Them to Schoolchildren

BackgroundCowpeas are important staple legumes among the rural poor in northern Ghana. Our objectives were to assess the iron and zinc content of cowpea landraces and identify factors that predict the intention of mothers/caregivers to give cowpeas to their schoolchildren.Methods and FindingsWe performed biochemical analysis on 14 landraces of cowpeas and assessed the opinion of 120 caregiver-child pairs on constructs based on the combined model of the Theory of Planned Behaviour and Health Belief Model. We used correlations and multiple regressions to measure simple associations between constructs and identify predictive constructs. Cowpea landraces contained iron and zinc in the range of 4.9–8.2 mg/100 g d.w and 2.7–4.1 mg/100 g d.w respectively. The landraces also contained high amounts of phytate (477–1110 mg/100 g d.w) and polyphenol (327–1055 mg/100 g d.w). Intention of mothers was strongly associated (rs = 0.72, P<0.001) with and predicted (β = 0.63, P<0.001) behaviour. The constructs, barriers (β = –0.42, P = 0.001) and attitudes towards behaviour (β = 0.25, P<0.028), significantly predicted intention albeit the predictive ability of the model was weak.ConclusionsWe conclude that some cowpea landraces from northern Ghana have appreciable amounts of iron and zinc but probably with poor bioavailability. Attitudes towards giving cowpeas and perception of barriers are important predictors of caregivers’ intention to give cowpeas to their schoolchildren. Finally our results suggest that increasing knowledge on nutritional benefits of cowpeas may increase health values caregivers hold for their children in support of giving cowpeas to schoolchildren.

“…Potassium content of samples varied from 17074.00 to 24078.00 mg kg -1 and significantly higher mean values were recorded in genotypes 98K-5301 and ITOOK-1060 compared to the rest of the genotypes.The mean calcium content ranged between 2236.70 and 8677.70 mg kg -1 in genotype 98K-5301 and genotype Pan311, respectively. In a study of 20 cowpea landraces in Benin, Madode et al (2012) reported calcium content variation of 700-1400 mg kg -1 , while a range of 56-104 mg kg -1 and 37-54 mg kg -1 are reported for iron and zinc respectively. Similarly, the highest mean phosphorus content was recorded in genotype 98K-5301 with the concentration amount of (5375.30 mg kg -1 ), while the lowest mean value was obtained in genotypes IT845-2246 (3834.30 mg kg -1 ).…”

“…However, the highest concentration was recorded in genotype TVU-14196 and was found to be the best source of iron among the genotypes, but far lower than the values reported by Ano and Ubonchi (2008) in Nigeria. According to Madode et al (2012), the differences between the various studies could be attributed to varietal differences, but are more likely to result from differences in soil fertility. The variation of both micronutrients and macronutrients observed in the current study might be attributed to the differential ability of the genotypes to absorb the mineral elements from the soil and transport them into the plant system (Shegro et al, 2012).…”

Information on genetic variability among genotypes is useful in crop improvement programmes. The study was carried out to determine the variability of nutritional composition in the immature pods of selected cowpea genotypes for use in breeding for nutritional qualities. ). The multivariate analysis showed wide genetic variability among the genotypes which could be exploited in selecting suitable parents when breeding for nutritional qualities. High heritability estimates were also observed in most of the traits evaluated indicating potential genetic gain when breeding for these traits. The present study revealed the genetic potential of the genotypes studied and their importance for use in the breeding programme aimed towards combating nutritional deficiencies and food insecurity in South Africa.

“…In Nigeria, they are also used in preparing other food products such as fried cowpea cakes, bean soup, and a steamed popular delicacy called moinmoin. Nutritionally, cowpea seeds contain 61%-66% carbohydrates, 24%-25% proteins, and 1.0%-2.0% lipids (Bressoni, 1985;Madode, Linnemann, Nout, Vosman, & Hounhouigan, 2012).…”

Moinmoin is a steamed cowpea seed‐based pudding native to Nigeria. This study evaluated the physicochemical, proximate, and sensory properties of moinmoin from a blend of cowpea and water yam flours. The pudding was prepared by varying the proportion of cowpea to water yam flour (CWYP). The blends were in the ratio 75:25% (CWYP1), 50:50% (CWYP2), and 100:0% cowpea flour (CPP) which served as the control. Physicochemical evaluation indicated that the products will have good keeping quality and reconstitute easily. Protein content was 26.90%, 20.10%, and 17.60% for CPP, CWYP1 and CWYP2, respectively, and the presence of water yam significantly (p < .05) increased the crude fiber, ash, and carbohydrate contents of the cowpea/water yam products relative to the control. Pasting properties revealed that regardless of the proportion of water yam in the mixture, the moinmoin samples cooked at approximately the same time; and sensory evaluation showed that CWYP1 was best preferred in terms of taste, flavor, color, and overall acceptability. These findings suggest that the cowpea/water yam pudding can meet the nutritional demands of a meal and that the 75%–25% cowpea/water yam mixture was the most acceptable. The study contributes to the knowledge nutritious products with desirable organoleptic qualities from a blend of cowpea and water yam flour, allowing for up to 50% water yam substitution. It also provides an alternative way of utilizing water yam thus preventing wastage during peak production and ensuring food and nutritional security because of the balanced products obtained.
