Zinc (Zn) is essential for swine and poultry and native Zn concentrations in feedstuffs are too low to meet their Zn requirement. Dietary Zn bioavailability is affected by phytate, phytase and Zn supplemented in organic form is considered... more
Phytases are phosphohydrolytic enzymes that initiate stepwise removal of phosphate from phytate. Simple-stomached species such as swine, poultry, and fish require extrinsic phytase to digest phytate, the major form of phosphorus in... more
Cowpea (Vigna unguiculata (L.) Walp) is a hardy legume crop with a potential to withstand extremes of water stress and temperature. It is rich in anti-nutritional factors like Raffinose Family Oligosaccharides (RFOs) and Phytic Acid (PA)... more
Plants constitute an alternative source of proteins in the human diet, with advantages over animal proteins because of their low content of saturated fats and absence of cholesterol. Within the framework of a wider research project on the... more
Various proteins play important roles in hypertension and a number of plants have been tested for their efficacy in modulating hypertension. Angiotensin 1-converting enzyme, renin and extracellular regulated kinase 2(ERK2) proteins,... more
A community-based dietary diversification/modification intervention, employing a quasiexperimental design with a nonequivalent control group, was conducted in two intervention and two control villages in rural Southern Malawi. The aim was... more
Coca leaves (Erythroxylum coca) have been promoted as a food that could address the dietary deficiencies of the Andean population, but this is based on nutrient analyses of a small sample of leaves. We assessed the nutritional potential... more
Multigrain composite mixes were prepared from different cereals, legumes, millets, nuts along with condiments by different processes. Multigrain composite mixes had 10 to 12% moisture, 56 to 61% carbohydrate, 15 to 20% protein, 9 to 13%... more
Plant seeds that have high phytate content are used as animal feed. Phytases, enzymes that catalyze the breakdown of phytate into inorganic phosphorus and myoinositol phosphate derivatives, have been intensively studied in recent years... more
Analysis of chemical composition of 13 locally available underutilized green leafy vegetables (GLV) was the objective of this study. Moisture, ash and ether extract of the greens were in the range of 73–95 g/100 g, 0.77–3.54 g/100 g and... more
Cookie samples were prepared with 0–30% of the wheat flour substituted with fibres from apple, lemon, wheat and wheat bran. The effects of increased levels of fibres from different sources on the nutritional properties of cookie samples... more
A method is described for the determination of phytic acid in various plant materials and feeds based on isotachophoresis. The electrophoretic migration properties of phytic acid, the lower inositol phosphates, and phosphate were... more
Common beans (Phaseolus vulgaris) are the most important legume crops. They represent a major source of micronutrients and a target for essential trace mineral enhancement (i.e. biofortification). To investigate mineral accumulation... more
The World Health Organization ranked it as the seventh most important preventable risk for disease, disability, and death in 2002 [2]. Since an important factor in its causation is the poor bioavailability of iron in the cereal-based... more
Low phytic acid (lpa) crops are potentially eco-friendly alternative to conventional normal phytic acid (PA) crops, improving mineral bioavailability in monogastric animals as well as decreasing phosphate pollution. The lpa crops... more
The mineral content of legumes is generally high, but the bioavailability is poor due to the presence of phytate, which is a main inhibitor of Fe and Zn absorption. Some legumes also contain considerable amounts of Fe-binding polyphenols... more
The effects of maize-bran phytate and of a polyphenol (tannic acid) on iron absorption from a white-bread meal were tested in 199 subjects. The phytate content was varied by adding different concentrations of phytate-free and ordinary... more
Balanites aegyptiaca Del. kernels were chemically, physically and morphologically characterized. Crude oil (49.0%) and crude protein (32.4%) were the two major constituents of the kernels. Phytic acid content was relatively high compared... more
