Maize is a staple food for millions of people in sub-Saharan Africa where a significant number of people suffer from vitamin A deficiency. Yellow maize contains both pro-vitamin A and nonprovitamin A carotenoids with potential health benefits to humans. An improvement in the concentration of thes...

An analysis of the recent trend in cassava area, production and yield during 1993-96 revealed an impressive increase in Tamil Nadu, which is the predominant state where cassava is grown as an industrial crop. Its present yield of 29 t/ha is the highest in the world. Even though the overall nation...

Cassava is widely consumed in Africa where malnutrition is rampant; there is, therefore, a major effort to produce micronutrient biofortified cassava. Adoption of such cassava genotypes will largely depend on their agronomic performance, resistance to biotic stresses, and the stability of these t...

Vitamin A Deficiency (VAD) is a major public health problem in Sub-Saharan Africa affecting 33 million preschool-age children. Enrichment of maize varieties with provitamin A could provide sustainable and affordable solution to VAD. This study was conducted to understand the extent of GEI effects...

People in vast areas of the tropics suffer from vitamin A deficiency, resulting in progressive eye damage and eventually leading to blindness. Improving the content of vitamin A precursors in staple crops could alleviate or solve such a problem. The objective of this work was to study the range o...

The cassava core collection (601 genotypes) was evaluated for root and leaf contents of micronutrient minerals, ascorbic acid, and carotene. Wide genetic variability was observed for all measurements, indicating that there is good potential for exploiting and improving the nutritive value of cass...

BACKGROUND: Orange-fleshed sweetpotato (OFSP) can be used to tackle vitamin A deficiency, a major public health problem in most developing countries. In East Africa, common ways of using sweetpotato include drying and subsequent storage. The aim of the study was to investigate the impact of dryin...

Different drying treatments, cross flow, greenhouse solar, and open-air sun, were applied to an American orange-fleshed sweetpotato variety. Trans-?-carotene losses in flour made from dried chips varied between 16 and 34% in all treatments. Hot air cross flow drying retained significantly more pr...
