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...

Research in Rwanda demonstrated that orangefleshed sweetpotato (OFSP) purée (steamed, mashed roots) was an economically viable, vitamin A enhancing ingredient in baked products when the purée was produced and used in the same bakery. Having a storable, packaged OFSP purée produced by a firm to su...

Bananas are important staples in tropical and sub-tropical regions and their potential as a source of provitamin A has recently attracted attention for biofortification. A collection of 189 banana genotypes (AAB-plantains, M. acuminata cultivars and bred hybrids) was screened to determine variabi...

Introduction. Chips or crisps are the most important foods usually fried; they are presented in the form of thin discs (chips) or sometimes in the form of sticks (French fries). Materials and methods. Chips were prepared starting from pulp samples resulting from five hybrids of plantain and banan...

Development of pro-vitamin A (PVA) biofortified staple crops has been promoted as an option for addressing vitamin A deficiency in humans. Recently, crtRBI, lcyE and zep1 genes of carotenoid biosynthesis pathway have been identified as contributors to PVA accumulation in maize endosperm. High phe...
