Introduction – Vitamin A deficiency (VAD) is a widespread health problem in Eastern Africa where banana is a staple food crop. Research has shown that certain banana cultivars grown outside Eastern Africa are rich in provitamin A carotenoids (pVACs) and could thus be utilized in addressing VAD in...

Carotenoid content in cassava roots has been increased through biofortification programs as a strategy to combat vitamin A deficiency. However, incorporation of biofortified cassava into both traditional and industrial food processing has yet to be fully assessed. The objective of this study was ...

The B-carotene content of five cassava varieties and products as well as B-carotene bioavailability in cassava grit from TMS 01/1371 were undertaken using 240 one-day old Arbor acre broiler strain randomly divided into eight groups of 30 birds each. Each group comprised a triplicate of 10 birds e...

Among the groups of naturally occurring pigments, carotenoids serve numerous purposes in plants, including antioxidant activity and protection of the photosynthetic apparatus from the excess of light. Alongside with essential mineral elements, these pigments are well known to have high impact on ...

Twenty-two genotypes of deep yellow fleshed D. dumetorum were analysed for carotenoids using High Performance Liquid Chromatography (HPLC) and for similarities in their provitamin A characteristics using Cluster Analysis (CA). The contribution of each carotenoid to provitamin A content was invest...

Cassava is currently the third most important source of calories in the tropics and consumed as a staple food. Several cassava varieties have yellow flesh color, and contain moderate amounts of carotenoid or beta-carotene which is a precursor of vitamin A. Consumption of carotene rich foods is th...
