High-quality cassava starch (HQCS) produced from high-yielding low-cyanide improved variety, TMS 30572, was mixed with durum wheat semolina (DWS) on a replacement basis to produce flour samples containing 0, 20, 30, 50, 70, and 100% starch. They were analyzed for chemical composition (proximate, amylose, free sugars, starch, wet gluten, cyanide) functional properties (pasting, swelling power, solubility, water absorption, binding, damage, diastatic α-amylase activity, dough mixing,...
Abstract Improved varieties have agronomic advantages over local varieties,but not much attention has been given to understand the nutritional content of improved cowpea released in Swaziland. This study investigated physical and properties Five (IT-04K-321-2, IT-97K-390-2, IT-18, IT-16, IT-99K-494-6) one variety (Mtilane, as check) were analyzed for chemical properties. The results showed that there variations seed weight values ranged between 12.5 18.5 g per 100 weight. protein from 25.38%...
Cassava, a staple food in sub-Saharan Africa, does not provide adequate amounts of pro-vitamin A (VA) carotenoids and has been targeted for biofortification (i.e. selectively breeding cultivars increased nutrient density with agroeconomically acceptable characteristics). However, the accessibility pro-VA absorption different cassava remains unknown. Here, we used coupled vitro digestion/Caco-2 cell uptake model to screen relative β-carotene (βC) 10 varying concentrations βC. After cooking...
Cassava contains little zinc, iron, and beta-carotene, yet it is the primary staple crop of over 250 million Africans. This study used a 24-hour dietary recall to test hypothesis that among healthy children aged 2-5 years in Nigeria Kenya, cassava's contribution childrens' daily diets inversely related intakes vitamin A. Dietary demographic data anthropometric measurements were collected from 449 Kenyan 793 Nigerian children. Among 89% derived at least 25% their energy cassava, while 31%...
Cowpea, an indigenous crop to sub-Saharan Africa, is found mainly in the dry savanna regions along with cereals such as millets and sorghum. Cowpea grown primarily for human consumption of grains, which are rich protein, carbohydrates contain some minerals. The development deployment cowpea varieties higher nutritional value will be immense benefit consumers. As a first step enhancement mineral content several germplasm lines (1541) different origins obtained from genetic resources unit at...
Abstract Background Inadequate protein intake is known to be deleterious in animals. Using WHO consensus documents for human nutrient requirements, the protein:energy ratio (P:E) of an adequate diet > 5%. Cassava has a very low content. This study tested hypothesis that Nigerian and Kenyan children consuming cassava as their staple food are at greater risk inadequate dietary than those who consume less cassava. Methods A 24 hour recall was used determine 656 449 aged 2-5 years residing...
Summary Cassava flour has potential for multiple applications in the food industry. To develop cassava varieties targeted household and industrial uses, it is necessary to evaluate varietal environmental variations fresh root yield, cyanide physicochemical properties. A total of 303 379 were grown at International Institute Tropical Agriculture research farm, Nigeria 2000 2001, respectively, harvested 12 months after planting. The genotypic content as well genotype × year interactions on...
We previously demonstrated that the quantity of β-carotene (BC) partitioning in mixed micelles during simulated small intestinal digestion, i.e., bioaccessibility, boiled cassava is highly correlated with BC content different cultivars. However, also traditionally prepared by fermentation and roasting. These methods preparation have potential to affect both retention bioaccessibility BC. Here, we first compared cassava, gari (fermentation followed roasting), fufu sieving cooking into a...
Background As part of the HarvestPlus provitamin A-biofortified cassava program in Nigeria we conducted a survey to determine intake and prevalence vitamin A deficiency among children 6-59 months women childbearing age state Akwa Ibom. Methods cluster-randomized cross-sectional was 2011 Ibom, Nigeria. The usual food nutrient intakes were estimated using multi-pass 24-hour recall with repeated on subsample. Blood samples collected analyze for serum retinol, ferritin, acute phase proteins as...
Many people in sub-Saharan Africa suffer from protein malnutrition; this results negative health and economic impacts. Winged bean ( Psophocarpus tetragonolobus (L.) DC.) is a tropical underutilized legume with beneficial nutritional characteristics such as high content, which may help to alleviate these problems. The proximate composition (fat, moisture crude protein, ash, carbohydrate) antinutrient (tannin phytate) level of winged seeds tubers were determined using 50 accessions. In the...
Abstract Within communities in Osun and Imo States of Nigeria, farmer–processors grew processed a diverse set improved landrace cassava varieties into the locally popular foods, gari , eba fufu . Local 15 main were grown ‘mother baby trials’ design each state. Mother trials with three replications by renown their community for processing skills. Baby managed other farmer–processors. The objective was to identify food quality criteria inform demand‐led breeding benefit users, especially...
Cassava is a major staple food in many tropical regions, but certain varieties remain hard and difficult to chew even after boiling, making them less appealing consumers. Preferences generally lean toward cassava roots that cook quickly possess sweet taste. This study explored the relationship between cassava’s dry matter content optimal cooking time (CT), specifically examining how these factors relate sensory attributes like softness chewability. Twenty varieties, aged 10 12 months, were...
Deficiencies of vitamin A, iron, and zinc are widespread in sub-Saharan Africa, where the diets mainly plant-based intakes animal products low. The overall objective this investigation was to determine extent genetic variation these micronutrients 16 yellow-seeded improved maize varieties, 109 inbred lines (60 from mid-altitude 49 lowland/savannah agroecologies), 162 cassava clones resistant mosaic disease. varieties were analysed for physical chemical characteristics total carotene content;...
The rate of cassava leaf consumption in Africa was assessed by a combination informal interviews, the use questionnaires and information from literature. Countries were rated to have high, average, low, or no leaves. mode preparation studied with six housewives who are nationals Congo (3), Sierra Leone (1), Madagascar Nigeria (1). In each case, procedure observed leaf-picking field serving cooked dish. first matured up position 9 10 selected for consumption. tender petioles stem also taken....
Twenty elite early-maturing (75-90 days) tropical maize varieties grown in three diverse agroecologies West Africa were evaluated to identify with high kernel-Fe and -Zn bioavailable Fe levels. Bioavailable iron was assessed using an vitro digestion/Caco-2 cell model. Significant (P < 0.001) varietal differences observed mean The ranges 15.5-19.1 mg kg(-)(1) for 16.5-20.5 Zn. Genetic component accounted 34% of the total variation kernel-Zn 11% Mean ranged between 4% below 49% above reference...
ABSTRACT Leaves of two varieties cassava (Manihot esculenta Crantz) – TME1 (local) and TMS30572 (improved) were subjected to African household processing (heat-treated, pounded cooked crushed, ground cooked) compared for proximate composition, minerals, vitamins antinutritional factors. The methods had no effect on ash, lipids, protein, fiber, total carbohydrate, carotene, calcium, magnesium, potassium, sodium, phosphorus, copper, zinc manganese but produced diminution in free sugars (23.2%...
